I wanted to meet the theoretical physicist Lisa Randall because of a novel I’m trying to write. My editor thought the problem was the main character, who was supposed to be a writer and a mother. To the editor, she didn’t seem like a very good writer, and she screamed at her children all the time; she was certainly a terrible mother. “You mean the first-person narrator, called ‘N’?” “I obviously don’t think you’re a bad mother or a bad writer,” my editor said. “Just the character.” I gave the manuscript to a friend, who said that the problem was clear. “You’ve put everything negative about yourself into the character, and none of the good stuff. You have to find a way to admire her more.” The
A new theory claims to have solved five of the biggest problems in physics all at once. The theory was developed by a group of French physicists at the University of Paris-Saclay, and it introduces a few new particles in an attempt to unify multiple different theories to solve five of the biggest problems in physics: dark matter, cosmic inflation, the strong CP problem, neutrino oscillations, and baryogenesis. All of these problems in our current physics model are in some way related to the mysteries of quantum mechanics. The theory, dubbed SMASH, expands the Standard Model of physics. The Standard Model is the catalog of every type particle that physicists know about. Included in the model are
Dark matter is the most abundant form of mass in our Universe. If you were to add up all the stars, planets, lifeforms, gas, dust, plasma and more - all the known, “normal” matter in our Universe - it would only account for about 15-to-17% of the total gravitation that we see. The remaining mass, outclassing the normal matter by a 5:1 ratio, must be completely invisible, meaning it doesn’t absorb or emit light at all. Yet it must interact gravitationally, enabling it to form large-scale structure in the Universe and to hold galaxies together. So why, then, can’t it form black holes? Black holes aren’t the only thing dark matter can’t form; it also can’t create dark matter stars, planets or dark
