How will the universe end if it keeps expanding?

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 will happen to the expanding universe once all the energy after the Big Bang has been used up?

The universe will eventually stop expanding and start collapsing in on itself, the so-called “Big Crunch.” If the density of the universe is less than this critical density, then the geometry of space is “open” and “negatively curved” like the surface of a saddle.

Is the universe going to expand forever?

Even though we don’t actually know what dark energy is, we can now answer the original question — yes, the universe will expand forever and we’ll experience a “big freeze,” not a “big crunch.”

What is the Big Freeze theory of the universe?

The Big Freeze This theory requires the Universe to be either flat or negatively curved. It maintains that the Universe will expand forever, getting colder and colder. The theory does, however, require that the acceleration of the expansion either remains constant or slows down.

What will happen to the universe after the Big Bang?

The rate of this expansion may eventually tear the Universe apart, forcing it to end in a Big Rip. Alternatively, the Universe could ‘shrink’, decrease or decay, effectively reversing the Big Bang and destroying the Universe in a Big Crunch. A third theory is described as the Big Freeze.

Does the acceleration of the expansion of the universe slow down?

The theory does, however, require that the acceleration of the expansion either remains constant or slows down. It is possible that, depending on the nature of Dark Energy, the Universe’s expansion rate could slow in the distant future; for example, if the Dark Energy was Quintessence, it could vary in its affect over time.
