    The expansion of the universe is accelerating! Yay!!!

    Meh dark matter and energy are still hiding.

    Actually, the answer is simple. The universe isn't being "pushed apart" by the Dark Force. TIME itself is slowing down. You saw it here first.

    YAY !! Give out Nobel prizes for the people with the best guess. :shadedshu
    The Nobel prizes have become a joke. Especially the peace prize.

    The Nobel Peace Prize is such a laughable farce is has discredited the whole Nobel thing. I remember as a young lad, "Nobel" was it. The ultimate. The most revered. The smartest. The people that gave their professional best and dedicated their lives in the pursuit of what they are being credited for.

    But now, particularly after a nonsense of peace prizes, the term Nobel has lost brand and credibility.

    In a Galaxy Far Far...you know the rest.
    Could it just still be the initial acceleration form the big bang?

    Finding dark matter wasn't the goal of their work. Observing supernovae gave them clue that universe is expanding faster. They didn't guess anything.

    Interesting point. But that initial acceleration would rather decrease by time. But on the contrary it's only increasing. So there's something else than Inflation which lasted no more than 10^−32 seconds after the Big Bang. But if Inflation was faster than light (which it really was) then maybe you're right and in this case the decrease of the expansion will appear .. someday ... who knows when.

    Thanks to the link on cosmological inflation. OK, I have a new theory that solves both apparent acceleration and also the "flat universe": TIME is not consistent in the x, y and z. In fact, even along x, y, and z themselves, time might not be consistent and might asymptotically decline.

    This might be proven if universe flatness and universe acceleration are correlated, and the observed supernova shifts are in one cosmological plane, and if the colour shift is greater the further away the event is from the reference point.

    There might be some other interesting corollaries, such as the universe might be more-infinite, but due to the time itself changing towards our "observed boundary"we think the universe is more-bounded when it might not be.

    You could argue that if time does slow down from our reference point the further away you are then we are actually unable to ever know or measure with any certainty anything close to or beyond this boundary.

    Enough brainbending already! Back to internet pr0n. ;)

    Is the universe being pushed apart by dark energy? Or are there other universes out there PULLING it apart with gravity? RIDDLE ME THIS

    Yes that can be the case. We can't receive any information faster than the speed of light and this limitation creates a "horizon". What happens beyond that horizon is out of our reach. If we imagine that there are some galaxies that got pushed further away with the speed greater than light we can't observe that. That's why we can't see big bang which happened 14 billion years ago. But if it was only possible to travel really really far where the Big Bang's information didn't get yet then we could watch the Big Bang from there. In this case by moving really really far in space we could see the past. It only makes me think that maybe time doesn't even exist maybe it's just some kind of byproduct of space. Because events at the atomic and subatomic level seem to depend on the future as well as the past which is really strange.

    But yeah let's go back to pron :)

    Interesting. If there are other universes, then do they lie in our space-time? And if they not then can their gravity still affect our world

    Mm.. The reason we cant see the big bang is because of the massive cosmic microwave radiation. It's like a huge wall to our telescopes. Otherwise the light has had sufficient time to travel to us.
    As for other universes sharing space time with us, they probably dont or else they would be apart of our universe.

    In this image, some of the blue spots are thought to be "bruises" from other universes-IE their gravity or somesuch force. Look up Kashlinksy's Dark Flow theory

    Interesting thread, I am some what of a space buff and subscribe to many space related podcasts to keep upto date and find space totally amazing, the advancements in telescopes in the last 20 years has been incredible, I dont know if we will ever know what "dark energy" is though.

    The fact that we can only see about 4% of the known universe tells you it is full of stuff we cant see, ie dark energy/matter.

    When the JWST gets launched we will find out more, the next few decades will be very interesting :)

    Relic radiation hm... I thought it was too faint. I just remember Hawking said that slight variations in the temperature of CMBR lead to formation of galaxies. Will read more about. Here's a nice link:

    http://skyserver.sdss.org/dr1/en/astro/universe/universe.asp



    String theory says that Big Bang (aka creation of our universe) was caused by other Universe. So there was some kind of "tunnel" or what? Maybe after inflation it got shut?


    And thanks for links. I also found a couple of links

    Yeah and the funny thing is back in the day (14 billion years ago) there wasn't dark energy but lots of dark matter. The universe was more shiny.

    SK-1 is right
    It will come a day when space and time will be unified. It means that time is still the same since the first bing bang and einstein was wrong about his constant if you all know. In fact that formula is right(at least we take it) When space and time will unify that formula is going to be the unification.
    Although einstein was wrong about the "logic" in physics about time. That way, he could never unify time and space.
    @SK-1
    happy nobel price man :)

    Also, scientists at CERN found neutrino to be faster than light....
    The bigger the universe, the less "part" it takes the same mass from time.
    (I will win nobel for this :) )

    I lost respect for the Nobel when Castro was a candidate one year.

    I was under the impression that space/time is already unified. That is why they are always referred to together. Do you mean one day we will have a "Theory of everything?" Like String theory?

    And the neutrino that was recorded faster than light hasnt been verified yet.

    mailman can be so short sighted. Peace prizes are judged from a "grand scheme of things" point of view.

    Castro was nominated by his own press via an online petition for the peace prize. I assure you he was never in any kind of contention LOL.

    Actually what spacetime is, this formula: x+y+z+T
    I don't mean this kind of unification though :p
    Also, you cannot verify something faster than light, with the speed of light....

    No. It's called M-theory.

    As noted in a recent issue of new scientist, the expansion of the universe causes a lot of problems for quantum mechanics since qm sees every unit of space as encoding information. So either each unit gets bigger, which distorts the information it stores or information is not being conserved. It's a real problem.

    An by the way, most physicists are coming to the belief that neither space nor time are real but are just constructs that happen to arise from more basic principles.

    Please try to collect all the little chunks of what was once your mind before you leave. Thanks. :D :toast:

    If space-time is built of "bricks" then where are those "bricks" located? Inside some other space-time? That's scary.

    Any man with a drop of common sense never put much weight into quantum mechanics. A dead cat in a box doesnt bring on fits of logic IMO. Quantum mechanics seemed more like "We have no clue. Therefore it MUST BE quantum mechanics at work."
