Does probability actually exist in the physical universe or is it a function of our ignorance?

If I'm rolling a dice, I don't know which way it's going to land.

So therefore, I put in a probability.

But does that mean that there's an actual probabilistic,

unknowable thing in the universe?

Is the universe flipping a coin somewhere or is it always deterministic?

All probability is actually subjective.

Uncertainty and randomness are subjective.

If you don't know what the outcome's going to be, so you roll a dice,

that's because you individually do not know.

It's not because there is uncertainty there deeply in the universe.

What we know about quantum theory is that all physically possible things occur.

This leads to the concept of the multiverse.

And rather than refute all of the failed ways of trying to understand quantum theory,

we're just going to take seriously what the equations of quantum theory say.

What we are compelled to think about quantum theory given the experiment is that

every single possible thing that can happen does happen.

This means that there is no inherent uncertainty in the universe,

because everything that can happen actually will happen.

It's not like some things will happen and won't happen.

Everything happens.

Now you occupy a single universe.
