Why Does Everything Decay Into Lead
If you look at a copy of the periodic table, you might notice that basically every element after lead is labelled as radioactive. And the vast majority of those elements wind up decaying into some version of lead eventually. But why is...

Does Antimatter Explain Why There's Something Rather Than Nothing?
The most precious substance in our universe is not gold, nor oil. It’s not even printer ink. It’s antimatter. But it’s worth every penny of it’s very high cost, because it may hold the answer to the question of why anything exists in our...

Why Is 1/137 One of the Greatest Unsolved Problems In Physics?
The Fine Structure Constant is one the strangest numbers in all of physics. It’s the job of physicists to worry about numbers, but there’s one number that physicists have stressed about more than any other. That number is 0.00729735256 -...

No, Your Dog Doesn't Think You're the "Alpha"
The toughest, most dominant canine gets the resources and respect - or at least that's the idea that caught on culturally. Turns out, that's not necessarily how it works.

Are the Fundamental Constants Changing?
The laws of physics are the same everywhere in the universe. At least we astrophysicists hope so. After all, it's hard to unravel the complexities of distant parts of the universe if we don't know the basic rules. But what if this is...

Conservation of Nucleon Number
In this video Paul Andersen explains how the nucleon number and charge is conserved in all nuclear reactions and radioactive decay. Fission, fusion, alpha decay, beta decay, and gamma decay all conserve the number of neutrons and...
