At one-one-thousandth of a second after the Big Bang, the great annihilation event should have wiped out all matter, leaving a universe of only radiation. Why still don’t know why any matter survived. Well, a new finding from the LHC brings us one step closer to understanding why there’s something rather than nothing.

NEW EVIDENCE: Earth Had Rings (and Might Regain Them)

April 3rd, 2025

Check Out All PBS Earth Episodes: https://www.youtube.com/playlist?list=PLnNZYWyBGJ1F8ofFm4H9UTrHxqU8zngK4

Planet Earth is the jewel of the solar system—the shimmery blue oceans, the verdant green forests, the wispy whimsical cloud formations. Saturn is the only competitor for most gorgeous planet with that giant ring system. Hmm… what if we could put the jewel of the Earth in its own ring? Then no contest. Well, there’s an extremely good chance that Earth once DID have a ring system. At least, that’s the proposal by a recent study that has evidence that a mysterious burst in meteor activity nearly half a billion years ago was actually caused by that ancient ring system collapsing onto the Earth. And, you know, if we had a ring once maybe we can have one again.

How Astrophysics Can (LITERALLY) Save the World

March 13th, 2025

Giant space rocks are definitely going to hit the Earth again. We actually do know how to deflect them, but only if we find them and correctly assess their risk. But the solar system is a chaotic place. How is it even possible to tell if a space rock will one day collide with the Earth?

Your DNA’s Codes Are (Probably) From Outer Space

March 6th, 2025

Thank you to Cyber GhostVPN for Supporting PBS. Learn More About Cyber GhostVPN: https://www.cyberghostvpn.com/PBSSpaceTime

Did you know that many of us have up to 4% neanderthal DNA? And that 100% of your DNA may come from outer space? No joke. The biochemistry that defined the coding system of your DNA may have happened off-world, and perhaps even long before Earth existed.

Will The Big Bang Happen AGAIN (and Again)?

February 20th, 2025

How did the universe begin? How can something come from nothing? One way to “solve” this most difficult of philosophical conundrums is to avoid it altogether. Maybe the universe didn’t begin. Maybe the Big Bang was just one in an endless cycle.

The Final Barrier to (Nearly) Infinite Energy

February 13th, 2025

Thanks to Radiacode for sponsoring this video. Use the promo code “PBS” to get an exclusive 10% discount at: https://103.radiacode.com/PBS

They say fusion is 50 years away, no matter when you ask. Then why are billions suddenly being pumped into fusion startups? Yes to train LLMs, but there’s a reason the technobrats are bullish on fusion in particular. The fact is, the technological challenges have been chipped away and in many cases solved over the past decades, and there’s really no one deal-breaker difficulty remaining. One of the final challenges is deciding on the physical vessel to contain our mini artificial stars–and we have some pretty sci-fi options that are nearly ready to go.

The Crisis in Physics: Why the Higgs Boson Should NOT Exist!

January 30th, 2025

Learn More About Anydesk: https://anydesk.com/spacetime

According to quantum physics, the universe should have collapsed on itself in the instant after the Big Bang due to all particles being 100 million billion times heavier. Recent observations of the universe existing suggest that this may not have happened. Even more recent experiments at the Large Hardron Collider have failed to find out why. In particular, why the Higgs boson is light enough to allow the universe to exist. This is part of something known as the hierarchy problem, and some consider it to be the most important unsolved problem in physics.

Why Time Flows Differently Between Galaxies

January 23rd, 2025

Thanks to Radiacode for sponsoring this video. Use the promo code “PBS” to get an exclusive 10% discount at: https://103.radiacode.com/PBS

The universe is expanding and that expansion is accelerating under the power of dark energy and eventually all matter and energy will be dispersed over such unthinkable distances that nothing can stop space from blowing up infinitely. Unless of course cosmologists blundered and dark energy doesn’t even exist. Then it’s back to the drawing board.

How Many Black Holes Are In The Solar System?

Dark matter has eluded us for many decades. Even our most advanced particle colliders and sophisticated underground detectors have come up short. But it may be that we can finally solve this mystery with a much simpler experiment, involving a ray of light, a good clock, and the planet Mars.

Does Infinity – Infinity = an Electron?

What do you get if you take something that’s infinitely massive and combining with something else that’s negative infinitely massive? You get a single electron, at least that’s what it looks like in our most precise way of describing the quantum world.
