First question...
Where did all of the matter to form the universe come from?
The law of conservation of energy states that energy cannot be created or destroyed. While it can be transformed from one form to another, the total amount of energy in the universe remains constant. Scientists in all fields, including astronomy, biology, chemistry, physics, and Earth science use this idea every day: The total amount of energy remains constant no matter what changes happen in any physical system.
