Ethan SiegelinStarts With A Bang!Ask Ethan: Why are inertial and gravitational mass equivalent?The mass that gravitates and the mass that resists motion are, somehow, the same mass. But even Einstein didn’t know why this is so.Sep 64Sep 64
Ethan SiegelinStarts With A Bang!What do unexpected experimental results actually tell us?Scientific surprises, driven by experiment, are often how science advances. But more often than not, they’re just bad science.Sep 55Sep 55
Ethan SiegelinStarts With A Bang!Official verdict: JWST’s early galaxies didn’t break cosmologyThe “little red dots” were touted as being too massive, too early, for cosmology to explain. With new knowledge, everything adds up.Sep 46Sep 46
Ethan SiegelinStarts With A Bang!It’s important that weight and mass are not the sameHere on Earth, we commonly use terms like weight (in pounds) and mass (in kilograms) as though they’re interchangeable. They’re not.Sep 36Sep 36
