which hypothesis is most supported by astronomers?\no the universe is currently expanding and will continue to expand.\no stars could burn out, causing the universe to become dark and cold.\no gravity could pull galaxies back together, causing a reverse of the big bang.\no dark energy will pull the universe together to form a massive black hole.
Answer
Brief Explanations:
Astronomers have evidence from cosmic microwave background radiation, redshift of distant galaxies, etc. that the universe is expanding and this expansion is accelerating due to dark energy. The idea of the universe expanding continuously is well - supported. Stars burning out would be a long - term process but not the most prominent current view. The reverse of the Big Bang due to gravity is not in line with current understanding as the expansion is accelerating. Dark energy is causing expansion, not pulling the universe together to form a black hole.
Answer:
The universe is currently expanding and will continue to expand.
