Stars die because they run out of fuel to maintain a balance of the star's pressure and gravity, causing the star to die through cooling or a stellar explosion.

The Big Rip Theory is where the universe matter and space-time itself is being gradually ripped apart as the Universe expands.

In the big bounce theory, the universe repeatedly expands and contracts into a new "big bang", seesawing back and forth in a massively big-picture timeline.

Mars atmosphere is 95% carbon dioxide, 3% nitrogen, 1.6% argon, with the rest being traces of oxygen, water vapor, and other gases.

The Big Crunch is a hypothetical scenario for the end of the Universe, which the expansion reverses and re-collapses.

Likely not, with current technologies, the world as we know it would incur a mass extinction of most humans due to lowering temperatures, water bodies freezing, and gravitational instability.

While there are various theories speculating how the universe will end, we currently do not have a definite answer.

While there are theories that planet nine is a black hole backed by groups of astronomers, we do not know.

Pluto was demoted to a dwarf planet because it has not cleared the neighborhood around its orbit.
