Ask a Mathematician / Ask a Physicist Your Math and Physics Questions Answered Home About Faq ← Older posts Q: How is matter created? Can we create new matter and would that be useful? Posted on March 31, 2021 by The Physicist Physicist : This was an interesting back-and-forth, so the original questions are italicized . What was the energy at the start of the universe and how did it create matter? If the question is “how much?” or “where did it come from?”, the answers are unfortunately “a hell of a lot” and “we can only guess”. These are still very open questions. There are lots of clever guesses, but there isn’t much solid, direct data to pick out which guesses are good. As for how it became matter, that’s “easy”: when you get enough energy in one place, new particles form spontaneously. If the new particle has mass m, then the energy present is reduced by mc 2 . This is Einstein’s famous energy/mass conversion rate: E=mc 2 . Kinetic energy (the energy of movement) is the easiest |
