Is it true that the universe expands faster than the speed of light? I read this in a book but it seems to violate Einstein who said that NOTHING moves faster than light, including space itself I guess.

    No. Because the speed of the expansion of the universe can't really be quantified. It's not as if the universe is a balloon being inflated and expanding into the space nearby. The space in the universe itself is expanding. As in the space between atoms etc is getting larger all the time. I suggest you google universe hyper expansion, it's a really interesting topic

    I do think that Universe expands, but I Don't think that it expands faster than the speed of light, i believe that it can't be quantified

    No, you're right, I don't think anything can move faster than light that is naturally occurring. That being said, I think that the universe's expansion definitely can be qualified if we did tests and trials, but that would take a lot of resources, time, and money.

    Currently, I do not know how fast the universe is expanding. However, at one time in the past (right after the Big Bang), the universe was expanding much faster than the speed of light. The reason why this could happen is because Einstein only said that information and things can only move through space at a limited speed. However, space itself can expand and shrink at whatever speed it wants (although usually it predictably expands at a rate which I think was estimated by Hubble).

    yes really its expanding..but i advice u to read stephen hawking grand theory book or u can see the documentry show of it..you 'll get answer of all yr questions.

    in general theory of relativity einsteins has accept that glaxies speed is morethan the light's speed which is 299792458m/s

    This is a question that i have asked science teachers and physics teachers in colleges and also high schools and what i have gotten is this. The matter is not moving faster than the speed of light, but it is the boundries around the universe. the amount of room that is avaiable in the universe is expanding faster thanthe speed of light. You can actually look at it like a balloon with the outsides of it being the outside edge of the universe. that is expanding faster than the speed of light but yet the air inside the balloon does not travel nearly as fast. jsut as the galazxies are not going away from eachother that fast.

    in response to what hidfsfsdfsfsd said, the unvierse is thought to be expanding faster today than what it was right after the big bang because of something called dark matter and dark energy. not much is known abnout them but there is evidence that they are there and are having a major influence and actually speeding up the univrese faster than it ever has been going before.

    A yardstick (meter stick) is a little longer today than it was 5 billion years ago

    Space expands, and that expansion can be faster than the speed of light. Special and General relativity place constraints on the speed of objects - both massive and massless - but not on the speed at which space can expand.

    I'd read a while back about an experiment ran at Princeton that passed a laser pulse through a Cesium vapor which exceeded the speed of light, by a fairly substantial amount. IIRC the pulse supposedly exited the vapor before it had finished entering it., or something to that effect.

    Well the universe is approx. 13.7 billion years old but has an approximate radius of 77 billion light years. You do the math. Space has most certainly traveled faster than the speed of light and MUCH faster at that.
