I'm less comfortable with time travel than I am with the other hypotheses because you've got to throw...

time travel into the mix, which is a whole other thing, right?

So using Occam's razor, I try to focus on the simpler hypotheses and hypotheses not involving time travel is probably simpler.

It doesn't mean you can rule them out.

If you've got Occam's razor, you need to find the simplest explanation that

that satisfies all of the evidence.

So you need to take into account the evidence.

Interdimensional, let's hit that one.

There are three spatial dimensions and one time dimension, and we have all of the evidence, all of the experimental evidence, we have points to this.

We have theoretical derivations as to why this is.

There are no other dimensions.

I don't believe in interdimensional in that sense.

But I would ask somebody who is using the word interdimensional, I would ask them, what is a dimension?

And I think you'll very quickly find out that they don't really know what a dimension is.

So that term is, again, this catch-all term that is being used to describe something that can be here and then not here somehow and then be over there.

So there are other ways you can have something that looks interdimensional but wouldn't be interdimensional.

So there are other physics ways to do this.

One of them is...

So you can think of dark matter as one possibility.

So dark matter, about 85% of the mass of the universe is made of this material that we don't even know what it is.
