  1. Re:hmmmm on Pushing 800W of Wireless Power at 5 Meters · · Score: 1

    You have your choice: energy efficiency OR omnidirectional transmission. The two are mutually exclusive.

    They aren't mutually exclusive. You could have omnidirectional transmission and build a Dyson sphere around it, thereby not letting any energy go to waste.

    (FYI: This is rather tongue-in-cheek. I am aware this would defeat the purpose of having it wireless at all.)

  2. Re:Cool, and some questions on Black Hole At Center of Milky Way Confirmed · · Score: 4, Informative

    Are we on the same plane as the accretion disk?

    Yes.

    How close are we to the event horizon? How close is the sun to the event horizon?

    Far. 40-50 thousand light years.

    Is it possible to collect and examine the radiation from black hole by approaching it from the "top"?

    Yes, hypothetically. However, the black hole is not "feeding" at the moment, meaning there is not much radiation coming from it. If it were in full quasar mode, we would have identified it a long, long time ago.

    Ewww... drinking recycled waste from a star? None for me, thanks.

    I collect particles created at Fermilab and turn them into H and O, then combine them to make water.

  4. Re:Your thinking on A Third of Mars Could Have Been Underwater · · Score: 1

    To be fair, there is some evidence for a global flood. All you have to do is look on the tops of various mountain ranges and you'll find plenty of fossils and minerals to indicate is was underwater at one point.

    Of course, you have to ignore the fact that it can all be explained by plate tectonics.

  5. Re:What is The Truth about Mars? on A Third of Mars Could Have Been Underwater · · Score: 4, Interesting

    You mean interesting as in "Hmmm, we might want to have some means of space exploration in the next century at the latest"

    A century is a very short amount of time on the solar timeline. The Earth won't fall into the Sun for 5 billion years or so, and even then, the Sun will have lost enough mass that models predict the Earth may be flung off into deep space rather than falling into the Sun.

    The more immediate concern is that over the next 1 billion years, the luminosity of the Sun will increase about 10% or so, which should be fairly devastating to life on Earth. But, thats due to the Sun getting older, not the Earth getting closer.

  6. Re:Forgive me on Fraud Threat Halts Knuth's Hexadecimal-Dollar Checks · · Score: 1

    I've always believed that "ten" means "10" in any base, and its just that some bases you skip numbers in counting and others you add them.

    Example (Base Three):
    Zero, One, Two, Ten, Eleven, Twelve, Twenty, Twenty-one, Twenty-two, One hundred...

  7. Re:Interesting repercussions on Black Holes May Not Grow Beyond Certain Limit · · Score: 5, Interesting

    Why does everyone assume that nothingness is the default? From everything we've observed of the universe, it tends towards chaos and disorder (entropy). Nothingness is the complete lack of entropy, so why would should that be considered stable?

    And, by the way, there are branches of cosmology that contend that the universe, has, in fact, always been and will always be. It comes from the idea that as you measure time further and further backwards, you find yourself measuring time forwards again. It has something to do with string theory, but the math is way beyond me.

  9. Re:Fermi paradox on Number of ET Civilizations In Our Galaxy Is 37,964 · · Score: 4, Interesting

    You're missing an entire aspect to the Fermi paradox.

    The universe is old. VERY old. About 14 billion years. Earth is fairly young, about 4.5 billion years.

    Assuming intelligent alien life take about as long as intelligent Earth life to evolve (give or take a billion years), these other civilizations would have billions and billions of years ahead of us.

  10. Re:What I want to know. on Colliding Galaxies Reveal Colossal Black Holes · · Score: 1

    There is nothing outside the universe.

    And, I don't mean emptiness. I mean nothingness.

  11. Re:Government Involvement? on Obama & McCain Conflicting On Net Neutrality · · Score: 1

    I'd be interested in knowing exactly how you'd MAKE Comcast stop downthrottling bittorrent without, you know, making them. Care to elaborate?

    By demanding they stop their anti-neutrality practices, then switching to a different provider if they don't.

    And, don't give me that "but where I live there are no other options". If that's true, start petitioning other companies to provide service in your area, and start educating your neighbors about net neutrality and get them to support your demand for competition.

  12. Re:On the fence on Obama & McCain Conflicting On Net Neutrality · · Score: 1

    Free market, to me, gives me the impression that I have a choice among many competitors. Unfortunately where I live this isn't true. DSL doesn't work and I have only one cable provider to choose from.

    You have plenty of other companies to choose from. However, they have deemed that your market isn't profitable enough for them to get in to. The market is still free and open, you just live in an area without enough people/net users to be profitable for competition.

    The free market only means companies fighting for your money when your money is enough to be worth fighting fore.

    To really get the free market to support net neutrality, you have to convince the consumer that net neutrality is something they should require in order to spend their money.

    Wow, I really feel sorry for whatever company you work for. Its been my experience that within a field, people care more what schools are good in that field than what schools are good overall.

    In engineering, for example, you'd expect a student from Purdue or Texas or MIT or UC-Berkley to be looked at in a much better light for their high engineering standards.

  15. Re:An observation and 2 question2 on Do We Live In a Giant Cosmic Bubble? · · Score: 1

    The question: if things only look farther away, does that make travel to other solar systems more likely? I mean, could that mean that, say, Alpha Centuri is less than the four light years away we think it is?

    There may be a slight effect at that short distance. However, we're talking about interglatic scale here. Its like saying "Mars may be closer than we think, so does that mean the cubical next to me may be closer as well"

    The second question may answer the first: how big is this bubble?

    BIG. Huge. Gigantic. Orders of magnitude larger than you can imagine.

  16. Re:I concur and have the following questions. on Do We Live In a Giant Cosmic Bubble? · · Score: 1

    Where are the other globules?

    Outside our light cone.

    What happens if we hit one?

    We won't. They're too far away and moving much too quickly for us to ever catch them, even if we were to travel at the speed of light.

    Where did the globules originate?

    The exact cause of this phenomena is still unclear and, in fact, may never be clear. The idea is that a rapidly expanding universe would have laws of physics unrelated to our current ones, so our understanding can only go back so far. (We're talking about the first few microseconds after the big bang)

    Is that larger void a super-large globule itself inside a still larger void? If so, see questions 1-4.

    Maybe?
