Hi everyone,

I just watched an interesting talk from string theorist Brian Greene and he said something that really captured my curiosity. He mentioned that in the universe there is a list of about 20 incredibly important numbers that we have measured extensively. He then says that if those numbers had any other values then what they do there would be a huge chance the universe wouldn't exist at all.

So my question was, and I am sorry if this is the wrong forum, what are these numbers?

Thanks for the help.
