starts when two atoms slam together to form one, heavier atom
The correct response is: starts when two atoms slam together to form one, heavier atom.
Nuclear fusion is a process in which two atoms slam together to form one, heavier atom. So the correct response is "starts when two atoms slam together to form one, heavier atom". This process releases a large amount of energy and is the principle behind how the sun and other stars produce energy. It occurs at incredibly high temperatures and pressures, forcing the atomic nuclei to overcome the electrostatic repulsion and come close enough for the strong nuclear force to bind them together. To confirm this information, you can also search for "nuclear fusion" in reliable scientific sources.

What does the evidence supporting the Big Bang theory assume about the universe when it began? Select the two correct answers.(1 point) Responses It was contracting It was contracting It was extremely hot. It was extremely hot. It was composed of ice. It was composed of ice. It was very tiny.
The correct responses are:
- It was extremely hot.
- It was very tiny.
The evidence supporting the Big Bang theory assumes that the universe began as an extremely hot and compact state, often referred to as a singularity or a small point.
