mostly likely its that the universe may continue to expand
reason: Its a theory called the Big Bang theory that basically tells us about the existence of the universe and how it has formed things in our universe such as galaxies and is still expanding today also it's a Law called Hubble Law that says the greater the distance of a galaxy from us the faster it recedes which also shows proof of universe expansion
Currently, the most supported theory about the future of the universe is that the universe may continue to expand and as it expands, it will experience a reduction in temperature until the universe becomes too cold to support life. This is known as the Big Chill theory.
