Can Quantum Fluctuations Create a New Universe?

Sabine post Can Quantum Fluctuations Create a New Universe? from patreon

[This is a transcript.]

The future is dark, and I don’t mean the upcoming US elections, I mean that stars in the universe will eventually all burn out. They’ll clump together and form black holes. The black holes will evaporate, leaving behind nothing but a very thinly distributed, cold, and dark gas. And ...

[This is a transcript with links to references.]

There are a lot of bad arguments against nuclear power. For example, that it’d just be too simple a solution to climate change, we need to make the transition difficult and painful. That’s not a good argument because it’s not actually that simple to prevent...

This video is all about Albert Einstein, yes, that guy again. Einstein is famous for his theory of general relativity. It’s taught us that gravity is not a force. And that’s probably the most misunderstood physics fact, ever. Like, even physicists get it wrong, all the time. Gravity is not a...
