Earthlike Planet Orbiting Nearby Star
The Bad Astronomer writes "Astronomers in Europe have announced the discovery of a planet with only 5 times the Earth's mass, orbiting a red dwarf star 20 light years away. It orbits the star so closely that it only takes 13 days to go around... but the star is so cool that the temperature of the planet is between 0 and 40 Celsius. At this temperature there could be liquid water. Models indicate the planet is either rocky like the Earth or covered in an ocean. While it's not known if there actually is liquid water on the planet, this is a really big discovery, and indicates that we are getting ever closer to finding another Earth orbiting an alien star."
This is a really big discovery...
And that, my friends, is the understatement of the millennium.

So, the temperature range indicates that it can probably be made hospitable for humans. Sure, we might have to bring a lot of our own oxygen and water to start with, but otherwise, we just need a colony ship. And, of course, the gravity is pretty strong (2.25 Gs) so we will have trouble with that. And, it being so close to the star, there might be a big radiation problem, forcing humans to go underground. But that wouldn't be too bad, because it would make gravity a bit less of a problem.
What I think is the coolest thing is that this is the smallest extrasolar planet found so far. We are getting close to being able to detect earth-sized planets. Once we do, I think the number of potentially colonizable planets will go up quite a bit.
We are currently developing technologies which allow a maximum speed of 0.6 X the speed of light.
if you create a probe with an ion drive and send it off in the next 10 years we could be looking at surveys of the planet in question by 2070.

My biggest hope is that before I die we will have proof of alien life, hopefully a spaceship will land in Times Square so there will be know question about it. This is a very exciting time, every time Scientists make a new discovery like this I feel that much closer to my dream.

Even if the planet consists of zephyr, gravity must be a bitch here
1)It has 2.25G's,
2)It's probably tidal-locked which means quakes so living underground is not easy
3)The surface is probably soaked with radiation where it faces the sun and cold where it does not.
4)If there is any atmosphere it is probably turbulent due to hot and cold sides.
Even if I could travel a light-year a minute for a buck, I'd never consider trying to live there. Next?
So should we classify a planet like this as Class "M"?
Assuming its the same density as Earth, cube root of 5 is 1.7, so 1.7x the radius. Gravity is mass/r^2, 5/1.7^2 x earth, so 1.7 or 70% more. ie surface gravity only goes up with the cube root of mass, for a constant density, so 5x isn't as bad as it sounds. But if it has more rock, and less iron core, the surface might me much nicer.
20 light years. So that would take us 20 years to get there travelling at the speed of light, or slightly longer going not quite as fast?

Indeed quite unlike our windless, quake-free, constant-temperature planet.
Sorry but no intelligent life there. Nothing that weighs more than a couple milligrams could ever have the energy to move around on its own with the gravity from that much mass. The eath has triple the mass of the moon and 6x the gravity or something like that. So 5x the earth's mass equals....like a freakin lot of gravity! I would weigh a couple thousand pounds there. Even a little alien chipmunk couldn't move around. I don't care if they would get their energy from food or the sun or magic or whatever, the amount of energy it would take to take a couple steps or even just slither around at 1 MPH would be more than the caloric energy of all the creature's matter being burned and sunlight doesn't give nearly enough either. So yeah, anything alive there is standing still and is very small which means it can't possibly be intelligent. And before you even say it, a couple feet down in a body of water, any organic cell structures would instantly be crushed from the pressure. Water magnifies gravitational pressure even more since it doesn't compress.

I haven't run any mathematical models, but given that there's a Neptune-mass (15 Earth mass) planet orbiting inside this planet's orbit (5.4 day orbit vs 13 day orbit), I'd guess that that's enough of a disruption to at least prevent a 1:1 tidal lock. There may be some kind of lock at another resonance (eg Mercury's 2:3 lock) but that would allow for rotation relative to the star and thus more-even heating.
2.25 gees is uncomfortable but tolerable (carry someone your own weight piggyback and you're almost there), and largely irrelevant to any water-dwelling critters.
However, the larger problem -- that I didn't see any of the articles explicitly raise -- it that there's likely a Venus-like greenhouse with the temperature much hotter than the 0-40C based on the equilibrium temperature of a rocky body at that distance from the primary. We can hope not, but we'd need a reason why not.
Based on our system, anything Venus-size or larger has a thick atmosphere, except Earth, and Earth is an anomaly because it got whacked by something massive (Mars mass) late in its formation, blowing most of the volatiles -- and the material that makes up the Moon -- off the planet altogether. (However, such late-stage super-impacts may be not all that unusual; it could explain some other oddities of our system, such as Uranus's tilt.)

Except we know from Star Trek: The Next Generation that the Progenitors seeded the primordial seas of thousands of worlds with fragments of their DNA -- not as a tribute to their greatness, but as a tribute to their existence. Which begs the question, what role does evolution really play in all of this?

Lovely image gallery, but you should have included some of this.
I was staring at that a while; I knew I did something wrong when I didn't get exactly 0. Of course you can't set a = c, a is an acceleration. Duh! I also lost my paragraphing because I posted as HTML.
My excuse is that I hit submit instead of preview. I've been an anonymous coward for a long time (note the UID) so I was unaware of these quirks of membership. Otherwise I wouldn't have posted this before noting that there's no way that shouldn't have come out to exactly 0.
Nevertheless, c happens to be a really really big number, so what I actually calculated in Newtonian Mechanics when setting a = c would be accelerating to light speed in one second, and then doing the same in one second on the other end. In relativity, T comes out to, survey says: less than 42 seconds, coming to a halt beside the target planet. Interestingly, even making the planet 10 times closer or 10 times farther only changes the result by a few seconds.

At 134 million mph (one-fifth the speed of light) we could get there in a quick 5 generations or so. At the current record of about 25,000 mph (achieved by Stafford, Young and Cernan on May 26, 1969, almost 38 years ago), it would take more than half a million years to make the journey. I was getting all set to pack but I think there's gonna have to be a breakthrough or two first.
We are currently developing technologies which allow a maximum speed of 0.6 X the speed of light.

Correct me if I'm wrong (IANARS), the Voyager 1's current velocity is 17.2km/s which translate to 0.000057c. This is currently earth's fastest spacecraft. Shouldn't we be thinking about breaking 0.00006c before 0.6c? And a 0.6c probe within 10 years? Are you kidding?

If this planet has 2.25 earth's gravity, then maybe we can adapt ourselves to it by traveling there in a ship with a centrifuge, and slowly increasing the speed of the centrifuge. By the time we get there (which with current technology, will take a lot longer than 20 years) we'd have adapted to handle the increased gravity. And as an added bonus, if we ever came back to earth, we'd be able to jump a lot higher.
First they found Kryptonite, now they've found a habitable planet with a red sun and stronger gravity.

The guy in this article makes the prediction that this planet is tidally locked with it's sun just as our Moon is with Earth, because...
So I'm left wondering about this planet. Does it rotate once every orbit due to the gravitational interaction with its star? This is what has happened to every moon in the solar system; they spin at the same rate they go around their parent bodies, so they always show one face to their parentThat is false. While many moons in the solar system are indeed tidally locked, they do not present a single face to their host planet at all times, with the exception of Charon.
Similarly, none of the planets in the solar system present a single face to the sun, with the exception of Uranus (which has nothing to do with tidal locking)
This effort would be better spent making sure this planet stays habitable.
No.
The best theoretical ion drive I've read about has an Isp of 10,000 seconds. That translates into an exhaust velocity of 100 kps (rounding up a bit).
Speed of light: A touch less than 300,000 kps.
Plugged into the rocket equation:
Mf+Mp / Mp = e^{300000/100) = 2.72 ^ 3000
Well, the Windows calculator tells me that's 5.0899334329769958439246007097416e+1303

Um, even if I screwed up somewhere, and I'm off by a factor of a million, that ain't good.
We are currently developing technologies which allow a maximum speed of 0.6 X the speed of light.
if you create a probe with an ion drive and send it off in the next 10 years we could be looking at surveys of the planet in question by 2070.
Again, correct me if I'm wrong but according to http://nmp.nasa.gov/ds1/tech/ionpropfaq.html, ion drives only deliver 10x the efficiency of chemical rockets. So to reach 0.6c, wouldn't an ion drive require more propellant than exists in the universe?
Do you think we could talk him into going there?
That's really close. The chances of it supporting life (what we know if it, anyway) are propbably low. The planet will be bombarded by radiation and magnetic interference. Not to mention that close it'll be tidal locked like some of the Moons in the Jovian system, which would make dough out of the crust. That planet better have one hell of a magnetic field and atmosphere if it plans to support life.
One can only wonder where we could be in terms of technological advancement if we spent 50% of what is spent on military spending worldwide on sciences.
Take me back to the cave with my spear and stones please.

If it is already inhabited then they could be twice as strong as us on average. With the higher radiation only things that could survive that extreme would remain and could better survive a radiation poisoned battlefield. The increased gravity would also mean stronger technology, airplanes would need stronger engines, spacecraft would need more thrust to break the orbit of their planet, all equipment would be better shielded against the radiation. If it is inhabited and they are on roughly the same technology level as us we had better hope they are friendly.
The star is a variable, so it may periodically hammer planets in a close orbit with massive flares. If the planet was covered in a sea that might offer enough protection from the hard radiation of the flares to let life develop. It's surprising that a planet in this new orbit wasn't disrupted by the Neptune size giant closer to the star.
Errrr, we have liquid water on earth at this temperature. More importantly, what is the air (if any) pressure. That will affect whether you have liquid water at 40C or not.

Emperor Clantos
Oh no. Not another android strike?
Chief Astronomer Zantooli
No your magnificence. Our automated tachyon telescope has locked on to a planet called Earth. It has detected our presence. Worse still, it has intelligent life and we are also detecting atom power weapons.
Emperor Clantos
Atom power weapons! My gods. They might use them against us! We must send a fleet of space troopers at once to confiscate them.
Chief Astronomer Zantooli
That's a bit risky. They might see them coming and kill a few of them. That won't do anything for your popularity.
Emperor Clantos
Hmm, you're right.
Chief Astronomer Zantooli
I suggest that we just vaporise the whole planet immediately. It's the safest way.
Emperor Clantos
Vaporise them!? Shouldn't we at least try to evacuate all their civilians first?
Chief Astronomer Zantooli
Not a good idea your magnificence. Again it puts our space troops at risk from enemy fire. Also, it would alert them and give them time to move their weapons somewhere else.
Emperor Clantos
But our people will surely complain about our killing so many civilians.
Chief Astronomer Zantooli
I'm not so sure. Who really cares about people so far away? If anyone kicks up a fuss we'll just say it's their government's fault for hiding the weapons amongst the population. Anyway, they use the same argument themselves all of the time when it comes to these people they call "terrorists". Whenever they detect them in an area, they just vaporise it without warning. If anyone complains about civilian deaths, they just blame it on the terrorists for "Hiding amongst the population".
Emperor Clantos
Hmmm. A clever transferral of blame indeed. These Earth people sound just like us. It's a shame we have to destroy them.
>4) If there is atmosphere like ours with water in it, it will hold some of the heat as it passes out of its suns rays and therefore should be just as turbulent.
A planet orbiting this close will likely be in tidal lock with one side always facing the star. This would have unplesant effects on any atmosphere.
I think it's interesting that in our extremely nascent explorations outside the solar system, we've already managed to locate practically a clone of earth. As other articles I read about this point out, this has major implications for how many other planets must exist that have conditions that would support life, i.e. if you sample .0000000000000000000000000000000000000000000000000 00000000000001% percent of the population and are already finding things, there must be a whole lotta more places out there just like it. Which is fascinating, because it essentially presents you with the following dichotomy: either you believe in creationism, or you believe in aliens. There's really no in between. Either we occupy a special, god-given place in the universe, or life as we know it began through the random agglomeration of organic compounds billions of years ago, in which case it would be practically a mathematical certainty that the same thing happened elsewhere.
I think there is a world market for maybe five personal web logs.
What about people that gain weight going from ~ 120lbs to say, 260. As its done over time, the body adapts and they are still able to walk around and live normally (although it does have adverse health effects) I think it is possible for people to adapt, but it will not be comfortable, especially for the first generation, and they will probably live a lot shorter. If this doesn't work however, It may however be possible to genetically engineer humans to live on high-G environments, increasing muscle mass, and bone density and thickness, as well as cardiovascular improvements.
I am aware of one experiment of putting someone in a high-G centerfuge and subjecting him to 1.5G's. The experiment was terminated early, due to the participant having a mild heart attack. Keep in mind, the participant wasn't given time to acclimate to the new environment gradually, and the experiment was short in duration, lasting only about a week, as it was designed more towards seeing if a high-G environment could help astronauts overcome loss of muscle mass and bone decalcification faster than normal after returning to earth, rather than colonization of a high-G environment.

I deny the existence of God, and this does not need to be un-scientific.
If the universe was created by some sentient being (I do not deny the possibility of this), then sure, some may call that God, I would just say that it is an alien life-form with great powers, not worth anything more than any other sentient being.
Now, giving you a Star Trek analogy, the being Q could easily be seen as God. But he is not God, even if he is omnipotent. He is a sentient being just like you and me.

Many if not all red dwarfs are flare stars, which may pose a serious radiation problem for nearby life. If the planet is tidally locked, that might actually help.

Would it be worth pointing a radio telescope at this thing?
In Klingon Federation sun like star orbits the planet !
The probe would have to be autonomous, anything beyond orbit of the star would have to be achievable by the probe's own logic. It might take intrasolar readings of the planet, which while remote would be far better than anything we could do from Earth.
Attempting planetary orbit would probably be too risky. Better to leave it in solar orbit sending back data.
Most of the cost would be in designing the probe, and getting it into orbit. Why send only one, which may fail en route? Send a dozen or so, and hope at least one survives. If more do, set them up as array antennas, or risk attempting planetary orbit with one.

The real issue perhaps with the gravity is the effect of living in zero gravity for the voyage to get there, and then transitioning to 2+G in a day! Perhaps using a centrifugal ship to gradually ramp up the gravity en-route. That'd give generations, wouldn't it? Then what if your signed up & three generations into the voyage & it turns out you're the weakest link, or there is a sudden realisation that your crew of super athletes should have been composed exclusively of lard asses... ...bummer dude!

Okay, so far all they know about it is its approximate mass and distance from its primary, and the length of its year (which is very much shorter than Earth's). The latter is approximately in the zone that would allow for temperatures such that water, if there is any, could be liquid, and suddenly it's Earth-like?
There are a lot of variables that go into determining whether a planet would actually be habitable at all, much less Earth-like. How much atmosphere has it got? What's the composition of the atmosphere? *Does* it have any significant amount of water (liquid or otherwise)? How long is its "day" (i.e., rotational period)? (Does it even have a day/night cycle, or is it tidally locked?) How massive is its moon, and what's its orbital period? Does it even _have_ a moon?
I'd expect suitable answers to these and many other questions before I'd be willing to call it "Earth-like".
Cut that out, or I will ship you to Norilsk in a box.
That close to a major body, even it it is "merely" a red dwarf star, and a planet is going to be tide-locked, one way or another. (Mercury's eliptical orbit is the only reason it managed to escape the same degree of tide-locking that Earth's Moon has.)
A tide-locked world, next to a star, isn't going to have a very large habitable zone. Any atmosphere could be expected to freeze solid on the dark side of the world. For starters.

Autonomous scientific observation from space (both inward and outward) has been a great success and it is a shame it was so casually tossed aside by politics.
Disclaimer: I watched Armstrong walk on the moon as a ten year old, and yes the world did stand together to watch one man. That was a different world, I don't think a game of golf on Mars would achive a similar reaction (if they were playing against martians it may be a different story).
And did you exchange a walk on part in the war for a lead role in a cage? - Pink Floyd.

Is your daily driver a formula 1 prepped vehicle? If not I seriously doubt you pull more than 1G on a dry skid pad. (when you say "my car" I'm assuming you are speaking of the vehicle you regularly drive). One of the best production cars for skidpad grip is the Ferrari Enzo and it "only" pulls about 1.05G.
Damn, I'm glad I'm not her manicurist.
Nostalgia's not what it used to be.
I would wonder how this test would work on creatures (or humans) reared from birth in a high-grav environment. I'd imagine that there may be some extra complications to being pregnant if one was initially low-grav native (although perhaps less if they started in high from a young age), but if a child were born and existed from day-1 under high-grav, he/she might very well have normal motor abilities and activities levels. It would also likely follow with the concept that many sci-fi books put forth (Niven/Weber/etc) wherein those natively frow hi-grav planets would end up with compensatory muscular/skeletal structures and possibly even other evolutionary differences over time. This would mean that on Earth, they would be damn strong - or at least rather solid - in comparison to the locals.
Yesterday we had kryptonite being found, today we learn about a large planet which is "earth like" and orbits a red sun (granted a red dwarf not a red giant)... I think we better start watching out for UFO sightings around corn fields.
>> It is [a religion]. Atheism assumes without evidence.

There is a difference between "I do not believe that god exists"
and "I believe that god does not exist".
The first is a good fit for the stamps analogy, the second is not.
I'd say it's more like calling black or white colors. In many cases, it may be more convenient to do so, but in actuality atheism is to religion as black is to color (that is to say, both tend towards being the lack of a particular value, or null-value).
Atheism is as much a religion as not collecting stamps is a hobby
Just last night as my girlfriend was hitting her crack pipe, she said "I need a new hobby!" I'm going to suggest she trade being a crack whore for not collecting stamps! I mean, even collecting stamps takes monsy so she'd still have to suck lots of cock, but NOT collecting stamps is free!
What a hobby! I might take up not collecting stamps myself! Lots cheaper than computers (which is a hobby that some people liken to being a crack whore).
Oh oh, I just found the fallacy in my statement, if she trades being a whore for not collecting stamps I'll NEVER get laid!
As Roseadanna said, "never mind".

WARNING: PEDANTIC
Do you really pull 2.25g in your car?
Let's give you the benefit of counting the Earth's gravity toward what you are feeling in your car on the skidpad. So you've got 1g straight down plus a lateral component N, and the total is 2.25.
The vectors form a right triangle, so a^2 + b^2 = c^2, right?
a = 1, b=N, c= 2.25
a^2 = 1, b^2 = N^2, c^2 = 5.0625
1 + N^2 = 5.0625
N^2 = 4.0625
N = 4.0625^.5 = ~2.01
Sports cars with special tires pull lateral around 1.0 G. Formula 1 cars and other extreme ground effects cars pull 2 g and more, but most people are never in one of those.
So, either
1) I've screwed up my physics
2) You've got a very uncommon car
3) Even adding regular gravity to what you can pull on a skidpad, you're maxing out your automotive G's closer to sqrt(2) = ~1.4
Well, that was fun. BTW, I agree with your point. 2.25G wouldn't kill us, tho I bet it would greatly reduce the lifespan of one's knees, hips and back. Certainly SOMETHING could live there tho. Probably alien warrior badasses who, should they come to Earth, could jump 50 feet and throw cars around like they were toys. That'd be cool, apart from how much it would suck. Hopefully we could get them hooked on television.

Stories like this now instantly get accepted as fact as soon as they're released. It's a long way from the old days when these stories got bashed and tested over and over. Unless you accept everything the moment it's announced, you can't be in today's science.
We now have somewhere to send the "B" ark.....all we have to do now is build it and five away all the free seats.
Undetectable Steganography? Yep, there's an app fo
It's too early for the human race to get to other planets.
We have not even learnt how to take care of Earth - why would we want to screw up an other planet?
For very large values of nearby...
Excuse me, but please get off my Pennisetum Clandestinum, eh!
The article doesn't say, but if you crank up the gravity enough, does their fur turn gold and do they start shouting something about "Freeza" or "Cell" when their training is done? :-)
Maybe archeologists will soon find the remains of the B-ark that brought our ancestors here
and we can salvage some of the necessary technology to build a new one.
On the other hand something really bothers me about settling another planet with rejects of descendents
of B-arkers. We also have to remember the fate of those that our ancestors left behind.
I believe that the original erroneous criteria for B-ark passenger selection was that the person appeared to be useless.
Because the end results were catastrophic and because we are B-ark descendants we need
to come up with different selection criteria or at least be more careful in applying the original criteria.
If this ends up qualifying everyone on the planet then we don't need to build the ark.
A more useful criterion might have something to do with a genetically based predisposition toward control of others.
But then again we might not need to build the ark because as in the previous case we all qualify.
Maybe for the sake of the other remaining life forms on this planet we should just build the stupid ark and get out
of here before we finish off the worthwhile life forms.
I, as I'm sure many geeks have, wondered what I would weigh on such a world.
I came up with gravity being 2.145x what it is on Earth on Gliese C.
So, unless I've made a mathematical error or bad assumption below (feel free to chide me for doing so), I would weigh over 400lb on Gliese C. I guess I'd better stop eatin' the junk.
d_E radial distance from center of the Earth
d_G radial distance from center of Gliese C
m_E mass of Earth
m_G mass of Gliese C
F_gE acceleration of gravity on Earth
F_gG acceleration of gravity on Gliese C
gP Gravitational proportionality of Gliese C over Earth
The size of Gliese C (per space.com) is 50% greater than earth
d_E = r_Earth = 6,372,797 m
d_G = r_Gliese = r_Earth * 1.5 = 9,559,196 m
The mass of Gliese C (per wikipedia.org) is 4.83 earth masses
m_E = 5.9736x10^24 kg
m_G = m_Gliese = m_Earth*4.83 = 28.852x10^24 kg
G = 6.6742x10^-11 N m^2/kg^2
F_g = (G*m_1*m_2)/d^2 (Newton's Law of Universal Gravitation)
Find the gravitational acceleration on Earth,
F_gE = (G*m_E)/d^2 = (6.6742x10^-11 N m^2/kg^2 * 5.9736x10^24 kg) / (6.37101x10^6 m)^2
F_gE = 9.822 m/s^2 (already known, but I calculated it for giggles as a way to check myself)
Find the gravitational acceleration on the Gliese C,
F_gG = (G*m_G)/d^2 = (6.6742 x 10^-11 N m^2/kg^2 * 28.852x10^24 kg) / (9.559196x10^6 m)^2
F_gG = 21.073 m/s^2
gP = 21.073 m/s^2 / 9.822 m/s^2 = 2.145
...if finding of this planet caused all the important instruments being pointed that way celebrating new horizons while at the same time an asteroid crept upon our backs and caused a total extinction level event.
Although it's not very probable, I wouldn't be a bit surprised. Not that we'd be able to do anything about it anyway considering our technological preparedness.
It is always better to be a first grade version of yourself than a second grade version of someone else.
Yes, something magical creating matter from nothing and violating the third law of thermodynamics makes much more sense. Scientists must have made up those GPS measurements that show it happening. Although you can evidence of prior eruptions of the hot spot that created Yellowstone National Park trailing up into Canada, it must have been something other than the plates moving as predicted. Of course the entire continent (planet?) must have been underwater, the earth must have gotten bigger but we have the same amount of water?
Actually, the earth used to be larger before a planetoid knocked the moon from it, but it does get slightly larger from asteroids and comets hitting it's surface from time to time.
You know, we wouldn't be having this problem with high-G if we had picked Bulrathi instead of Humans in the first place!
Man is the animal that laughs.
And occasionally whores for Karma.
I'm gonna make a claim without any kind of proof(just my gut feeling).
My belief is that the government knows that alien life exists, which is
part of the reason why they can already determine if a planet is
"suitable for life".
In addition, I think that revealing alien life exists would undermine all
of this "search for other life", which is raking in tons of money. So the
public is continually teased little-by-little thinking that progress is being
made when we already know the answer. Of course, this is all done in the name
of money.
Anyway, like I said, no proof, but it's just my gut feeling.
Do they even have them in Toronto? Real coffee shops are not chains. There's only one of each.
If you think Starbucks makes good coffee, you don't know what it's supposed to taste like.
Please do google for Agenda 21. I suggest you start with the documenary "Global Warming Swindle"2 478442170&q=global+warming+swindle
(which ridicules man-made global warming to be sure). You can find that on video.google.com
at http://video.google.com/videoplay?docid=449956202
I had a saturn iv and moon lander toy when I was a kid meaning I'm a little younger than you,
however I'm sure I would BUY a television to watch the Mars landing.
Starbucks is consistent. It taste the same regardless of where you go. It's not very good, as Starbucks' "trademark" is overroasted beans, but it's better than McDonald's or gas station coffee.
Are there no real coffee shops in Toronto? It's believable, I guess, Toronto is the armpit of Canada after all. Take a trip up to Montreal, I'm sure there's real coffee up there.
Don't let price fool you, good coffee isn't necessarily expensive, and a lot of expensive coffee is awful. Starbuck's pricing is mostly marketing. It relies on people assuming it must be good because it's expensive.
Don't know what you'd change exactly, but you might consider it if characteristics useful to that environment can be reliably added/induced.
I imagine there are good coffee shops in Toronto, I was just poking at you. Starbuck's isn't good coffee. If you think it is, I can only conclude that you've never had good coffee. I don't know Toronto very well, so I can't tell you where to go to find it.
You won't find it in corporate chains, at least not in North America. (Though there are places in the world where even free hotel coffee is excellent compared to North American faire.)
The point isn't that this is a place for us to live. The big deal here is that it's the closest we've found to an Earth-size planet yet, which brings us closer (we hope) in our search for extraterrestrial life. It's not that we're planning to live there--we're hoping to find life in places like that. More accurately, it's closer to the sort of place where we hope to find life. Personally, I don't find it all that exciting as a candidate for life. If I understand these things correctly, when the star expanded to a red giant it likely stripped off the planet's atmosphere. But it is exciting that we've found something so close to the Earth in size. Considering how hard it is to spot planets (by whatever method you use) from distances of light-years, that's pretty impressive.
There are objective differences in quality that aren't subject to taste. The beans that Starbuck's uses are mid range; not crap, but not excellent either. All else being equal, they'd be just fine as commuter coffee. Unfortunately, they then burn those beans for the majority of what they serve. If you order thier "mild" blend, it's sometimes still drinkable, but a long way from quality coffee. They're still handy, because as you say they're everywhere, and most of the time not garbage.
Tim Horton's uses lower quality beans, but they handle them more professionally. Unfortunately, they don't serve anything other than plain coffee, so you're out of luck if you like random crap thrown into it. *That* is a matter of taste, where as bean quality and roasting is not.
For coffee on the go, both are acceptable, because of their ubiquitousness, not their quality. I personally keep one of those Starbucks cash cards, because there's one on my way to class and it's better than the campus coffee. And the employees are much nicer than Tim Horton's.
There really is much better coffee out there. Go out and find it, when you're not in a rush, and enjoy it. Especially if you're making it at home, there's no reason to use Starbuck's beans. A quick Google tells me to suggest either Kensington Market or Roncesvalles (some sort of Ukranian district). I'd thought Toronto had a large Italian district as well, and that's probably also a good place to try.
Here's an idea I found for the power problem. Can someone translate this for the masses? IANAP, but it looks like it may be possible to use quantum entanglement for energy transfer. Ion or photon propulsion and a few GW (maybe TW) of power will get you there provided it gets funded, created, and scaled up.
Besides, in Civilization terms, that was a domination/conquest victory. If you're planning to win that way and end up taking long enough to reach the modern age, you usually end up nuking the $h17 out of the other civs.
Technological victory means that you manage to build a spaceship and send it off to Alpha Centauri before any of the other civs do. And, ironically, then wipe out mankind on Earth, as described in the "sequel" to Civilization, Sid Meier's Alpha Centauri.
Man, I can barely live with 2.5G of RAM. I wouldn't buy a cellphone with that little storage. I carry more that 2.5G in mp3 around all the time. No, no one should be forced to live with 2.5G. A 40G mandatory storage should be a basic human right.
