Are atoms on earth the same across the universe?

Question

Do the dynamics of atoms and their properties hold true across the universe?

In: Chemistry

Answer 1

I mean, we can only study things on Earth… But everything that has crashed here has been what we expect, and everything we can see looks like what we expect, so probiably.

The entire point of science is to extrapolate conclusions about things you can study to the things you cant, and worry about being wrong only when someone discoverers something inconsistent.
