Release this energy and you have, well, you have a nuclear explosion. Just as well there's an even stronger force than the electromagnetism holding our nuclei together. But it's not the strong force, as you might have imagined. At least not directly. Nuclei are held together by a quirk of nature, without which we would have no complex atoms, no chemistry, and certainly no labradoodles.

The Universe Itself Might Be Withholding the Gravity Particle From Us

Head to https://brilliant.org/Spacetime/ to start learning for free for 30 days. Plus, our viewers get 20% off an annual Premium subscription for unlimited daily access to everything Brilliant has to offer. To progress to the next level in understanding reality, we need to combine quantum mechanics and Einstein’s general relativity. And to do that, most physicists believe we need a theory of quantum gravity .. which means we need gravitons. But it also seems like the laws of physics make it impossible to ever detect this quantum particle of gravity. Almost like the universe is set up to keep the final answer forever out of our reach. So, can we outsmart the universe, catch a graviton, and finally solve physics?

But the only elementary particle actually flowing in the circuit is the negatively charged electron. And yet those flowing positive charges are there, in the form of a particle you may never have heard of.

Why Magnetic Monopoles SHOULD Exist

Sign Up on Patreon to get access to the Space Time Discord! https://www.patreon.com/pbsspacetime What happens if you cut a bar magnetic in half? We get two magnets, each with their own North and South poles. But what happens if you keep on cutting, into fourths and eighths and sixteenths and so on? Will we ever get to a single pole? I’ll spoil the answer for you: we don’t know! But the idea of magnetic monopoles remains one of physics’ most tantalizing maybes.

How Astrophysics Can (LITERALLY) Preserve Civilization

Remove your personal information from the web at https://joindeleteme.com/SPACETIME 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?
