I am not quite sure there is anything officially called "Eternal Universe" by astronomers.
If you mean that it continues expanding eternally, this currently seems to be the most likely scenario, since the Universe is not only expanding, but the expansion is speeding up (it expands faster now than in the past), and there is no particular reason to believe that the expansion will slow down.
There are possibilities on all subjects. It doesn't matter how large the possibility is, but there are on every subject. As there is a possibility that we all go insane, and commit suicide on this hour... Even though the possibility of this is close to none, there still is a possibility, in any way you can look at it. There is a possibility that there is life in the universe other than ours. We didn't find out yet, and space agencies like NASA are busy researching this subject. The Kepler Space Telescope is busy looking out for planets bigger than ours. By the time we know if there is other life in the universe, it will be at leas some years in the future, most likely tens, or maybe even hundreds of years. But you never know, maybe there isn't...
If the amount of dark matter and dark energy exceeds the critical density of the universe, it could lead to a scenario where the universe undergoes a "Big Crunch," collapsing back in on itself. However, current observations suggest that dark energy, which drives the universe's accelerated expansion, dominates over dark matter. As a result, the universe is more likely to continue expanding indefinitely rather than collapsing, leading to a cold, dark, and dilute state known as the "Big Freeze."
The most widely accepted explanation for the start of the universe is the Big Bang theory. This theory suggests that the universe began as a singularity that rapidly expanded about 13.8 billion years ago, creating everything we see today.
No, that doesn't seem likely.
Very likely, their are thousands maybe even millions of planets in the galaxy that are habitable, than their are trillions of galaxies.
The collapse of the universe inward is called "the Big Crunch" hypothesis. It suggests that the expansion of the universe will eventually halt and reverse, leading to a collapse of all matter back into a hot, dense state. However, current observations suggest that the universe is actually expanding at an accelerating rate, which makes a Big Crunch less likely.
The theory that suggests the universe may eventually shrink is often referred to as the "Big Crunch" hypothesis. This concept posits that after expanding, the universe could reverse its expansion due to gravitational forces, ultimately leading to a collapse. While this idea is one of several scenarios regarding the universe's fate, current observations indicate that the universe's expansion is accelerating, making the Big Crunch less likely.
Many scientists consider the possibility life exists elsewhere in our universe (and more particularly even within our own galaxy) quite likely. A few do not think it is likely.
That's a possibility; but the observational evidence shows that the Universe is expanding faster and faster - and it seems likely that this tendency will continue in the future. It seems likely that the Universe will continue expanding exponentially, doubling in size every 10 billion years or so. Thus, it doesn't seem as if it will collapse again.
Answer: I don't believe that any consensus has been reached, although it seems that more people are arguing that a "big crunch" is more likely that an endless expansion into increasing entropy. But this is definitely a question that you should ask again in about 15 years. Answer number 2: The ever-expanding Universe. The main reason this seems likely is that it has been observed that the expansion of the Universe is actually accelerating - i.e., it is expanding faster now than in the past. Answer number 3 : I agree with answer 2. The discovery of "dark energy" and the increasing rate of expansion of space favors the ever expanding Universe.
Although all the hydrogen in the sun and the stars will eventually be converted to helium or heavier elements, there is likely to be plenty of hydrogen atoms in outer space. This answer assumes, in line with current cosmological theories, that the universe does not end in a big crunch.

very likely to happen
The Oscillating Universe Theory is a cosmological model that combines both the Big Bang and the Big Crunch as part of a cyclical event. That is, if this theory holds true, then the Universe in which we live in exists between a Big Bang and a Big Crunch. In other words, our universe can be the first of a possible series of universes or it can be the nth universe in the series.

It wasn't "discovered". It was proposed, but according to the current astronomical knowledge, it isn't likely to happen.
The universe likely contains millions upon millions of black holes.
