Law of Conservation of Mass
TED-Ed explanation by Todd Ramsey
*Note* This video includes the scientific theory that the universe began as a "big bang". As Catholic scientists, we know that the "big bang" theory may or may not be correct. If it is correct, the next questions one should ask are, "What caused the big bang?" and "Who created the first matter?" Our ultimate answer to these very important questions is, "God!"
God is the creator and designer of all the universe! He loves each one of us, and made us each unique. He gave all human beings the gift of a soul and the ability to think and reason, and made us each "in His image and likeness" for a specific purpose.
It is pleasing to God when we use our intellect to try to understand the beautiful creation that He has made, and to learn more each day about how loving, powerful, and all-good God is!
