Ethan SiegelinStarts With A Bang!Ask Ethan: Could reinterpreting our data eliminate dark energy?Dark energy is one of the biggest mysteries in all the Universe. Is there some way to avoid “having to live with it?”Mar 3, 20237
Ethan SiegelinStarts With A Bang!Ask Ethan: Will physics ever see another Einstein or Newton?In all of science, no figures have changed the world more than Einstein and Newton. Will anyone ever be as revolutionary again?Jun 17, 202221
Ethan SiegelinStarts With A Bang!Ask Ethan: What if the Universe lives in a false vacuum state?There’s a big difference between the notions of ‘false vacuum’ and ‘true vacuum’ states. Here’s why we don’t want to live in the former.Nov 11, 20212Nov 11, 20212
Ethan SiegelinStarts With A Bang!Ask Ethan: What would happen if you traveled in a straight line forever?Is the Universe finite or infinite? Does it go on forever or loop back on itself? Here’s what would happen if you traveled forever.Feb 4, 20225Feb 4, 20225
Ethan SiegelinStarts With A Bang!Ask Ethan: How Can We See 46.1 Billion Light-Years Away In A 13.8 Billion Year Old Universe?In General Relativity, the fabric of space doesn’t remain static over time. Everything else depends on the details we measure.Feb 1, 20205Feb 1, 20205

Ethan SiegelinStarts With A Bang!Ask Ethan: How do we know the Universe’s temperature?We frequently say it’s 2.725 K: from the light left over all the way from the Big Bang. But that’s not all that’s in the Universe.Jan 21, 20222
Ethan SiegelinStarts With A Bang!Ask Ethan: Are galaxies without dark matter actually real?A few years ago, the first dark matter-free galaxies were announced, and then immediately disputed. Now, there are too many to ignore.Dec 17, 20214
