Ethan SiegelinStarts With A Bang!Ask Ethan: Is Earth the center of the Universe?In all directions, at great distances, the Universe looks younger, more uniform, and less evolved. Does that mean Earth must be the center?2d ago42d ago4
Ethan SiegelinStarts With A Bang!Your head lives a longer life than your feet doTime is relative, not absolute, as gravity and motion both cause time to dilate. Your head and feet, therefore, don’t age at the same rate.3d ago73d ago7
Ethan SiegelinStarts With A Bang!Why hasn’t JWST broken the cosmic distance record by more?Despite many ultra-distant galaxy candidates found with JWST, we still haven’t seen anything from the Universe’s first 250 million years.4d ago24d ago2
Ethan SiegelinStarts With A Bang!Shortest-lived quantum particles exhibit quantum entanglement, tooLHC scientists just showed that spooky quantum entanglement applies to the highest-energy, shortest-lived particles of all: top quarks.5d ago65d ago6
Ethan SiegelinStarts With A Bang!JWST shows a new side of planet formationJust 460 light-years away, the closest newborn protostars are forming in the Taurus molecular cloud. Here are JWST’s astonishing insights.6d ago86d ago8
Ethan SiegelinStarts With A Bang!Ask Ethan: Does space require dark energy in order to exist?It’s possible to remove all forms of matter, radiation, and curvature from space. When you do, dark energy still remains. Is this…Sep 278Sep 278
Ethan SiegelinStarts With A Bang!Hidden variable alternative to quantum spookiness failsDo we actually live in a deterministic Universe, despite quantum physics? An alternative, non-spooky interpretation has now been ruled out.Sep 2620Sep 2620
Ethan SiegelinStarts With A Bang!Longest, strongest black hole jets of all-time discoveredWith the discovery of Porphyrion, we’ve now seen black hole jets spanning 24 million light-years: the scale of the cosmic web.Sep 2511Sep 2511
Ethan SiegelinStarts With A Bang!Why we’ll never shoot Earth’s garbage into the SunIt would get rid of our hazardous, radioactive, and pollutive waste for good, but physics tells us it’s a losing strategy for elimination.Sep 2422Sep 2422
Ethan SiegelinStarts With A Bang!What JWST found in the extreme outer Milky WayAlmost all of the stars, planets, and interesting physics happens in the inner portions of galaxies. Is that conventional wisdom all wrong?Sep 236Sep 236
