What has 0% probability? If there are an infinite number of different universes/timelines, doesn't that mean nothing has 0% probability? If there are infinite unique universes, then by the time you have every universe with all the things you say are >0 probability, you have an additional infinite number to find

Doesn't the concept of infinity mean that nothing is impossible?

The probability of me rolling a dice numbered 1-6 and getting a 7 has 0 probability.

And once again if you want to start talking universes which don't observe our laws of nature then we aren't talking science.

no

From a mathematical pov, zero multiplied by infinity is zero. So something with a zero percent probability of happening will happen zero times in a sample of infinity.

No, the question just makes no sense. Just because you realise infinity has something to do with measure and number doesn't mean we can use it in calculations.

You wouldn't think 0 * ruler = 0 you'd think I was on crack.

I have no idea, but that doesn't make any sense to me. I thought Schrodinger's cat is either dead or alive, not both; I thought that whole thought experiment was designed to show that certain interpretations of quantum mechanics is flawed.

You're talking about different things. IF I showed you an experiment and said this happens. Some people think it's because A, some B, some C (A-C are explanations). You wouldn't assume that all those explanations make sense and then try to make them coherent with each other.
