Is it possible for a galaxy too fall back into its self?(even if they don't) What would happen?
Are you sure about that? In http://math.ucr.edu/home/baez/end.html I read:LURCH said:So, the same force that caused the galaxy to "clump together" into a galaxy in first place is still pulling that galaxy ever tighter together.
And you can show in the really long run, any isolated system consisting of sufficiently many point particles interacting gravitationally - even an apparently "gravitationally bound" system - will "boil off" as individual particles randomly happen to acquire enough kinetic energy to reach escape velocity.
A galaxy collapsing is a hypothetical scenario in which a galaxy, typically a spiral or elliptical galaxy, begins to collapse in on itself due to gravitational forces. This can happen when a galaxy's internal structures, such as stars and gas clouds, are no longer able to resist the pull of gravity.
The potential implications of a galaxy collapsing can vary depending on the specific circumstances. However, some possible consequences could include the destruction of stars and planetary systems, the formation of a supermassive black hole, and the disruption of galactic structures and dynamics.
While there are no confirmed instances of a galaxy collapsing in our observable universe, there are some ongoing observations of galaxies that appear to be in the early stages of collapse. However, it is important to note that the timescale for a galaxy collapse is incredibly long, and it is difficult to observe this process in real-time.
If a galaxy were to collapse near our own Milky Way, it could potentially have a significant impact on our solar system and planet. The changes in gravitational forces and the potential formation of a supermassive black hole could disrupt planetary orbits and cause catastrophic events on Earth.
Yes, there are ongoing studies and simulations being conducted by scientists to better understand the factors that contribute to a galaxy collapsing and the potential consequences. This research can help us gain a better understanding of the universe and potentially prepare for any future events that may occur.
