Can an expanding universe be infinite?

The universe encompasses everything in existence, from the smallest atom to the largest galaxy; since forming some 13.7 billion years ago in the Big Bang, it has been expanding and may be infinite in its scope.

Will the universe continue to expand or will it eventually contract?

The Universe will expand forever: If the mean density is less than the critical density, then there is insufficient mass within the universe to stop the expansion – the universe will expand forever. Ultimately, the galaxies will move increasingly further apart.

What will happen if the expansion of the universe continues forever?

There are two main ways for an expanding universe to die: The cosmos could eventually collapse back in on itself, or it could continue inflating forever. If gravity overpowers expansion, the cosmos will collapse in a Big Crunch. If the universe continues to expand indefinitely, as expected, we’ll face a Big Freeze.

What universe is one that continually goes through cycles of expansion and contraction?

oscillating Universe theory Variant of the ‘Big Bang’ theory in which it is suggested that the universe passes through successive cycles of expansion and contraction (or collapse).

Is there infinite matter in the universe?

The simple answer is that the Universe is not INFINITE. There is no infinite anything in this Finite Universe.

Will the universe expand forever or re collapse?

The fate of the universe is determined by its density. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will continue to expand indefinitely, resulting in the “Big Freeze” scenario below.

Is the universe expanding for kids?

The Universe is Expanding It’s growing larger and larger all the time. Not only is it growing larger, but the edge of the universe is expanding at a faster and faster rate. Scientists think that the edge of the universe is expanding faster than the speed of light. Timeline of the Universe over 13.77 billion years.

Is the universe expanding or collapsing?

There’s also the fact that not only is the universe as we know it expanding, but it’s accelerating in its expansion, with no sign whatsoever of it slowing down (let alone collapsing) anytime soon.
