Is the Hubble tension a real problem? #AskEthan Famed astronomer Wendy Freedman claims (including in an interview with me) that the Hubble tension may not be real. A large suite of evidence, rebutting many of her claims, suggests otherwise. bigthink.com/starts-with-a-…

JWST captures its most extreme gravitational lens ever Hubble previously viewed galaxy cluster Abell S1063, finding swirling, distorted lensed galaxies. With a JWST deep field of that same region, you won't believe what we saw. bigthink.com/starts-with-a-…

You can’t do your own research without doing your homework first Nearly everyone who claims to "do their own research" isn't conducting research at all. Most of them haven't even done their homework, and that's a huge part of the problem. bigthink.com/starts-with-a-…

JWST discovers how we’re able to see the Universe at all It's only because all of the neutral atoms in intergalactic space became ionized that we can see so far away through space. JWST, at last, has found who the culprit is. bigthink.com/starts-with-a-…

Busting the top 5 myths about the Big Bang There are lots of arguments against the Big Bang, and many proclamations that it's already been disproven. But those are mostly based on an incorrect depiction of what the Big Bang even is. bigthink.com/starts-with-a-…

What puzzles can the Vera Rubin Observatory help solve? #AskEthan The Vera C. Rubin Observatory has delighted the world with their first look observations. Now, here are the scientific advances this fully functional observatory should bring to us all. bigthink.com/starts-with-a-…

5 ways our naked-eye views of the night sky deceive us The night sky is a tremendous source of awe and wonder. And yet, when we look at it with our naked eyes, what we see isn't representative of what's actually out there. bigthink.com/starts-with-a-…

JWST’s early galaxies didn’t break the Universe. They revealed it. Why does JWST see so many bright, early galaxies? It's not because cosmology is broken. The answer has a lot to do with dust, or specifically, the lack of it in the early Universe. bigthink.com/starts-with-a-…

American science to soon face its largest brain drain in history The largest brain drain in history was when thousands of scientists left Nazi Germany; it became known as "Hitler's gift." America's current assault on science is set to surpass that. bigthink.com/starts-with-a-…

Do wormholes connect entangled particles, and will this lead to warp drives & subspace communication? Dr. Ethan Siegel discusses the massive implications of the ER = EPR conjecture. FULL INTERVIEW: youtu.be/l8m2IwhC1S4 #physics #quantum #StarTrek Ethan Siegel

A unique mission to both Uranus and Neptune could launch in 2034 We're seeking life on exoplanets, including on worlds much more massive than Earth. So why not actually go explore Uranus and Neptune here in our own backyard? bigthink.com/starts-with-a-…

The discovery of cosmic inflation @startswithabang

Could the CMB arise from galaxies, not the Big Bang? #AskEthan A very dubious claim has been making the rounds: that part or even all the CMB isn't of cosmic origin. Here's how that claim falls apart with even a cursory look at the science. bigthink.com/starts-with-a-…

Starts With a Bang podcast #119 – The CMB What's the big deal with the CMB? Why do we keep trying to do more science with it even after the Planck mission? What can we still learn from it? Patricio Gallardo and I answer these and many more questions! bigthink.com/starts-with-a-…

Did JWST catch the Ring Nebula forming new planets? Planet formation normally happens when new stellar systems are forming: in protoplanetary disks. But when a Sun-like star dies, it makes new dusty debris. Do new planets arise from the ashes? bigthink.com/starts-with-a-…

Humanity’s third interstellar object, 3I/ATLAS, is arriving now Interstellar object 3I/ATLAS is now being measured and characterized for the first time. Here's what we've learned about it so far, including comparisons to 'Oumuamua and Borisov. bigthink.com/starts-with-a-…

The top quark isn’t a loner after all: “toponium” is real! The top quark is the most massive, shortest lived particle of all. But it isn't always a "bare quark" that just decays; the LHC just revealed that the bound state of "toponium" is real! bigthink.com/starts-with-a-…

Jupiter endangers Earth, and may have extincted the dinosaurs Jupiter is often lauded as Earth's great cosmic shield and protector. But it's more foe than friend, and may have even triggered the great mass extinction that occurred 65 million years ago. bigthink.com/starts-with-a-…

Can we fix the worst prediction in all of science? #AskEthan The cosmological constant is the worst prediction in all of science, off by ~122 orders of magnitude from the observed value. Even worse: it's two unsolved problems in one. bigthink.com/starts-with-a-…
