What does scientific theory mean?
user
An open-ended conjecture about the natural world.  Scientists work towards testing their theories and modifying them, in a process called the scientific method, until a theory is confirmed as correct.

So they try to prove it?

Most scientists would say that the process of testing theories is more like a long game of tennis, which can go on for decades or centuries.  Every theory must be tested against all of the data that has been collected.  And every theory is part of an ongoing research program, and as new data comes in, a theory may need to be modified.  Sometimes a theory is modified many times, but it is still a part of an ongoing research program.

That is really interesting and cool.
