Is the Universe infinite, meaning that from now on it will never become nothing?

Question

We don't know if it was made out of nothing but do we know that it can never become nothing?

Does nothing even exist?

Oh but Steve you eliminated yourself. Big Bang is still a thought, it's not completely proven and I don't...well it might never be proven because you can't catch up with an expanding Universe unless it collapses..

Well I was just stating that the guy who told free thinkers not to post in this forum has said that to himself. So what if the Big Bang is the most popular theory, doesn't mean it's correct and doesn't mean those who believe it are superior to other thinkers.

Answer 1

They have recently discovered huge areas, in space where there is nothing. I believe it is a symmetrical opposite interactive universe, infinity is always was, always will be...and its opposite is nothingness never. If infinity were a living being (I call "Blisskeeper" to stay generic) he would know everything except, the meaning of the words time or space. If they don't exist to him, they don't actually exist period. Like death, all are concepts of vanity. Consider to positive charge negative is death, to North of magnetics South is death...there are billions of symmetrical opposite examples, but just because its opposite of doesnt mean it becomes non existent. I dont believe in the "Big Bang" the universe is both expanding (massless black holes were it spews out) and contracting (extreme mass black holes, "crunch phase transition) at the same time, one in the same yet on symmetrical opposite sides. This is imppossible to correlate with our feeble human minds, but after all my research, is the only way it makes sense to me. I reccommend a Brian Greene, (Norton publishing) book called "The Elegant Universe" A kind of Quantum Mechanics for Dummies universe overview. As much space that there is which include planets/stars etc...there is an equal amount of empty area.

Your "additional details" indicate that you do not understand how science works. You say, "Big Bang is still a thought, it's not completely proven."

Nothing in science is "completely proven." EVER. There is always an observation that, if made, would discard a theory. What science does is *disprove* theories. Theories make predictions of the outcomes of future experiments. If you do the experiment and it contradicts the theory, the theory is thrown out or modified. If the result is confirmed, the theory isn't proven, it's just not disproven. When a theory has been tested many, many times and never failed, it becomes accepted. But there's no such thing as "proven." For instance, If everyone started floating weightlessly tomorrow, we'd have to significantly rethink our ideas of gravity.

The Big Bang theory is the only widely accepted theory of cosmology. It has been tested many many times and survived. The Theory of General Relativity (probably the most tested, most accepted theory in all of science) requires the universe to be either Big Bang or Steady-State, and Steady-State is disproven. To say that the Big Bang is "just a thought" is severely disingenuous.

To answer the question: there is not enough gravity in the universe to halt the expansion. It will continue to expand forever.

EDIT: Nowhere did I claim that BB thinkers are better than other thinkers. They are, however, more correct because they can more correctly predict the outcomes of future experiments. The correctness doesn't come from its acceptance. Its acceptance comes from its correctness.

Answer 3

1) No, it's not infinite - we can (almost) see the edge, it's about 15 billion light years away.
2) Yes, we DO know it was 'made out of nothing' (see Big Bang)
3) Yes it can - there is still some (small) debate re: 'expanding for ever' V's 'the big crunch', however smart money is on the former, so eventually (in infinite time) all the matter / energy in the Universe will indeed be spread out to 'become nothing' ..
4) No - by definition, 'Nothing' = zero matter, so Nothing does not 'exist', however see 'Vacuum Energy'

PS this is the Science forum .. would the 'free thinkers' please stick to Arts & Humanities or Mythology & Folklore ... Poetry is not a valid Scientific Theory (Science doesn't CARE what you think, feel or wish for :-) )

Answer 4

The universe is one whole cosmic system of matter and energy of which Earth is a part. In this believe, there exists one and only one universe. In that sense, I do believe the universe is finite. However, I think space is infinite and more than one universe exist. Every universe expand in the same way, and that light could never pass its borders. That would explain why we never see other universes. No, I don't think everything started from nothing.

Answer 5

I don't think it's expanding. I think it's infinite. It's clearly not bound by time. It will always be because it was once. Nothing does exist, but we don't know what it is. "In darkness there is light, you just can't see it."

Answer 6

are you talking about infinite as in size, time or possibilities?
