That guy Albrecht is kindof a dick, huh? Ha.

Kirsten, it's possible, it's also a cool idea, but that's about far as it goes. As mentioned in the excellent article that you quoted, there is no evidence that multiple universes exist, and there might never be a way to prove or to disprove the idea. As the article mentions, the idea is a counter-argument against the so-called "anthropic principle", that the universe has been fine-tuned so that life on Earth could thrive. If there are multiple universes, each with a different set of fundamental physical constants, then we just happen to have grown in one of the (minority of) universes that is favorable toward life.

By proof I meant possible evidence. So basically it's a cool idea, but unlikely? Or if it is possible, then probably the other universes are much different from ours?
Physics is turning out to be better than I thought.


And that's the step before string or M theory! It's M theory that leads to parallel dimensions. It's not proven; it's just our best guess so far. It seems convoluted to me, but then, there were loads of people who thought this whole "earth revolving around the sun" thing wasn't exactly intuitive. After all, I'm sitting on my couch right now.






To be honest, you need to take things involving String Theory, Super Symmetry and M-Theory with a bit of a grain of salt. These are all mathematical models predicting that things could go one way or another. None of it has really been observed yet. There are actually a number of models out there. But mathematical "proof" or prediction cannot replace experimental physics.... and this is coming from someone who strictly wants to be a Theorist haha.

Adam-I take almost everything with a grain of salt.
I've heard some good things about Matt's suggestion, Not Even Wrong: The Failure of String Theory And the Search for Unity in Physical Law, though I haven't read it myself.
I was reading on Twitter (a great source, I know, don't judge) that they are finding proof of other universes. What do you guys think? Possible or just a cool idea?
