No of course I don't have proof, I have a reasonable explanation for what we observe around us (life seems to have originated from one original alive thing). The event you're proposing may very well happen (or could have happened already but noone noticed), but I don't think it would be very likely due to reasons stated above. And bacteria surviving is a completely different thing, they are far more complex and efficient than anything thats going to form spontaneously, even the new life forms ancestors 1 million generations later will probably not be as adapted to whatever environment it is. Like I said though, who knows, I'm not saying it can't happen, just that it makes sense that life would form once and then the headstart would make for a situation in which its hard for other lifeforms to develop.
I agree, I mean I haven't really come across any evidence that people like that (on the phone or texting all the time, headphones on as they walk down the block, etc) are worse off in any way, but theres just this knee-jerk disgust reaction that I have to it. Maybe its rude, maybe its the sight of someone who is just constantly consuming, or maybe I'm just old-fashioned (I'm 22). I don't know..discuss.
That ones easy, "life" (ie collections of reproducing molecules) developed once somehow and then out competed all later/other types of life for resources. I mean some little molecule thats something near alive can form in this room right now but its not gunna get enough "food" because me and my bacteria friends are going to be far better at getting, keeping, and utilizing those resources. Thats the nontechnical answer.
To the body, a transplanted organ is a big giant mass of cells that don't match the DNA of its own.
These cells that don't match the rest of your bodies DNA reproduce themselves.
Explain to me how that ISN'T the same thing as a cancer.
Noun
cancer (plural cancers)
(medicine, oncology, pathology) A disease in which the cells of a tissue undergo uncontrolled (and often rapid) proliferation.
transplant (plural transplants)
(medicine) An operation in which tissue or an organ is transplanted.
So there's the definitions, now what does that mean cancer is? It's what happens when a cell in your body starts dividing when it shouldn't due to a whole series of specific mutations (theres quite a few different things that could happen, if you want to get into it we can but honestly for out purposes you can just look it up)
What you must be thinking of is the person's body rejecting the organs which is an immune response. This is not due to "different DNA" as many of your cells at this point include altered DNA (assuming you're not 1 week old) because environmental stuff (radiation, chemicals you ingest, etc)have altered it and there is competition leading to natural selection taking place amongst your own cells all the time. Your body (i.e. immune system) doesn't normally attack these cells because they don't express anything that antigens (chemicals that have one end that stick to known bad things and the other that sticks to cells that eat them up) will stick to. This is because you were born with your cells having certain things sticking out of them and your body knows they should be there.
If you "get cancer" that means that cells your body sees as ok start dividing when they shouldn't and keep doing that but your body doesn't know how to stop it because they've mutated and stopped responding to the signals that tell them to stop growing/dividing. An organ transplant causes an immune response because the other persons organ is made up of cells that have foreign molecules at the ends that antigens will stick to because they haven't been trained not to during the course of your life (they see it as an infection). Two completely different things.
I'd say you dont get drunk for yourself, you get drunk with other people and watch them be drunk as you're drunk and hilarity ensues leaving everyone a winner. At least thats one reason being drunk. Theres also people who just turn into assholes but its possible to just stay away from them.
That doesn't solve any problems at all, the only thing you changed is that any law enforcement person who gets caught breaking with protocol can go to jail for it. 1)The average person is not going to be able to prove that because itd probably take them years to even figure out what the protocol is 2) Now the people getting paid to enforce laws would be spending way more time doing paper work than what their actual job is, what a waste of time.
ha.. scifi books (if you pick the right ones) plus physics books. Check out timeline by Michael Crichton, thats probably the best armchair time travel theory I've ever read, the second idea i had was based on that.
Well first of all I think if anyone is planning on time traveling using the second approach it would be prudent to destroy the original immediately (have vaporization be part of the process) to avoid the issues of copies. The second issue you brought up could be sidestepped with alternate (but often very similar) universes resulting (i.e. the multiverse interpretation of quantum mechanics), or some as yet undiscovered causality conservation law that would say that any action you take to change the future would be countered by some other change (i.e. you kill your grandfather, but then soon after someone figures out how to grow a clone of him and he is recreated, but then the original scientist and his lab are destroyed and the secret is lost)
Ok... so theres a couple of ways to get around such things while still staying scientifically consistent.
1) Traveling backwards in time by going faster than the speed of light you know [(1-v^2/c^2)^.5] (will take infinite energy, but were talking time travel so lets hand-wave that away... maybe you get it back on the return trip or something). So first youve got your machine that can speed you up that fast, also for the sake of argument lets say the force you can generate is so large that you get to the speed of light in less than planck time (the first trick), thereby not interacting with anyone or traveling anywhere before you lose all mass and travel at light speed. From there, if you think about it (to avoid the root of a negative), the direction that light travels must switch, so once again youd be traveling through time at the same speed as now relative to earth and at the same location, only everything would be running opposite. So what you wanna do is once agian use your ultimate acceleration device but turn it on for a fraction of a second less, and this amount of time your accelerating is related to how far back in time you end up when you then decelerate to zero V relative to the earth, now youre at a point backwards in time relative to where you started, but if you try to interact with anything you'll have to do it all backwards, and plus you're not in the right spot which just isnt going to be fun. So heres the second trick, now you once again accelerate to lightspeed and a little bit beyond really quickly. Now youre in the past traveling in the direction of causality as we know it, but in the wrong spot( probably the middle of nowhere, you can check this by sending some smaller time machines ahead of you programemd to come back that can sense the surroundings) so you just travel through space until you get to where you want, and now you do whatever it is you wanted to do back there.
2)You don't actually go back in time, but a copy of you does. If the state of every subatomic particle in your body could be detected very near to the time before youre sent back, you wouldnt know the difference. So we take that information, compress it in some way (your DNA is basically a compressed human being, think about that), then send that signal through a microscopic wormhole moving at relativistic speeds relative to its nearby partner who you keep in a safe location, with some way for it to decompress itself. When you exited the slow moving partner you would end up in the same location but in the past.
I knew a guy who did that. What you gotta do is find someone who will say they would hire you if only you had a CDL, you get a lawyer and go to court asking for permission to get the CDL (or they recommend you to the secretary of states office, something like that... you gotta deal with both) then youll probably need to pay some money (could be alot it sorta depends on the judge) for a bunch of random shit they basically make up amounts for and go to substance abuse counseling. Then you're good to go.
I'm 22 and my cars got all those wacky problems older cars get eventually (97 lumina, about 140k miles). I acutally kind of like it because I wouldn't have been bothered to learn anything about how that thing works if it wasn't for problems that needed to be fixed. I've heard the argument (they're making cars different now anyway so it's pointless to learn that) but funny enough thats always from people who pay 40 dollars to get their oil changed and fluids checked.
Well speaking for myself as a "scientist" (probably somewhat related to whatever you meant by that) I don't "accept" that a supreme being created the universe because it makes no difference. Theres no way for me to tell if he/she/it wants something in particular from me in return or whether I even have free will in choosing what I do/think to begin with, so I'll tuck that away with all the other possible explanations for things that are useless.
A metaphor: I ask myself why my car's brakes stick sometimes? Maybe it was gremlins jacking off onto the piston. Well no way to stop that if thats what it was so may as well act as if it was a problem I could do something about and if all else fails just get another caliper and hope the gremlins have moved on to somewhere else. Which is the same thing I'd do if I just couldn't figure it out to begin with for whatever reason(time, knowledge, etc). Thats the reason "scientists" put no stock in this supreme being idea, ie it's useless for anything besides social manipulation (which isn't necessarily a bad thing since groups of people who think the same about something will usually be more likely to work together for the bettering of the group despite other differences) and helping people through tough times. Add to that the whole God of the gaps thing (looks at history, even just whats occurred during your own lifetime so you don't have to worry about biases, and this is a blatantly obvious phenomenon)and a very reasonable explanation for peoples belief in a supreme being and the way that is/has been implemented into their lives will occur to you as well.
They need to calibrate it first to the individuals brain (oh so when they see a dog it looks like that) then compare the scans due to later stimuli to that. Theres no way an MRI is sensitive enough to anything common to all people when they process the image of a specific thing the signal to noise ratio would jsut be too small.
I could only get through about half this thread before I just got disgusted. Theres really that many people on slashdot falling prey to the horserace mentality? really? You guys don't see what you're playing into. Any discussion of these peoples actual platforms is completely missing from the discussion, its all about who's winning and what they did during the course of their campaign. Completely retarded, I can't believe that this shit really works. Don't you see that you're being pawns in the game between the two parties (and maybe if you're really cynical the mysterious overlords that really run things). Come on get a clue all these people are all assholes in ways you can never hope to be (do you think you run for president and win? Probably not, because theres a whole system in place stopping it), there will never be a politician you really agree with... the best that can happen is that their platform is clearly stated and once elected they are held accountable to it (and thats all right it arises out of the fact that there's a diversity of views in this country so theres no way around it). Whats not alright is that they get to never actually say anything about what their goals are and instead deflect the conversation towards this kind of he said she said crap that doesn't really matter.
Ok, I think everyone's replies to this have been wrong. What has happened isn't primarily the result of people being paid for specializing, or amount of free time, or the complexity of the field. The difference between the 1700's and today is that its necessary to use ever more complex (and expensive) machines to do it right. Any bio/chem lab worth its salt has millions of dollars in equipment, physics/astronomy/engineering is no better. To really make an impact across these fields would basically mean your a billionaire and even then it would be a giant undertaking just to set up and maintain the lab. This is why noone does it unless the government gives them money or they have a business plan allowing them to recoup costs.

They should be mercifully dragged out into the street and beaten mercilessly.
So are you suggesting that it be pitch black unless theres a car coming by so everyone without one stays inside all night?
Ha, didn't think of that
