Ethan SiegelinStarts With A Bang!Ask Ethan: Are we expanding along with the Universe?The mutual distance between well-separated galaxies increases with time as the Universe expands. What else expands, and what doesn’t?2d ago72d ago7
Ethan SiegelinStarts With A Bang!4 pervasive myths that cause us to abandon scienceIt’s not a gambit. It’s not fraud. It’s not driven by opinion, prejudice or bias. It’s not unchallengeable. And it’s more than facts alone.3d ago163d ago16
Ethan SiegelinStarts With A Bang!New LHC results refute Fermilab’s “hole” in the Standard ModelWith new W-boson, top quark, and Higgs boson measurements, the LHC contradicts earlier Fermilab results. The Standard Model still holds.4d ago14d ago1

Ethan SiegelinStarts With A Bang!Ask Ethan: Can you explain wide binaries and modified gravity?There are many theories of gravity out there, and many interpretations of wide binary star data. What have we really learned from it all?May 172May 172
Ethan SiegelinStarts With A Bang!Does the Universe expand by stretching or creating space?The evidence that the Universe is expanding is overwhelming. But how? By stretching the existing space, or by creating new space itself?May 1618May 1618
Ethan SiegelinStarts With A Bang!Our best idea for the “origin of gold” doesn’t add upIn 2017, we detected gold being forged in a neutron star-neutron star merger. Now, in 2024, the amounts created simply don’t add up.May 1511May 1511
Ethan SiegelinStarts With A Bang!New particle at last! Physicists detect the first “glueball”Glueballs are an unusual, unconfirmed Standard Model prediction, suggesting bound states of gluons alone exist. We just found our first…May 146May 146
