Timeline of the far future
For example, astrophysics can say how planets and stars form, affect each other, and die; particle physics can say how atoms 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 guesses about what might happen in the future.
