The ultimate fate of our universe may be the [[heat death of the universe]]. Before that happens, it is possible to predict that the following will happen.⏎

</ref> Before we go further, it is worth noting that our [[local group|local group of galaxies]] are bound by gravitation, and its changes and aging can be discussed separate from the rest of the universe.⏎
⏎
For example, [[astrophysics]] can say how [[planet]]s and [[star]]s form, affect each other, and die; [[particle physics]] can say how [[atom]]s and other matter act over time; [[evolutionary biology]] can allow us to see how living things change over time; and [[plate tectonics]] can say how continents shift over time.  By observing the past and present, astrophysicists, particle physicists, evolutionary biologists and geologists can make good guesses about what might happen in the future.  We call these g(contracted; show full)
