Druid, tell me which direction time is from you.

You can't, it's at 90 degrees from all three physical dimensions. And what about all the other dimensions? M-theory says that spacetime is an 11-dimensional membrane. Can you lean into those other dimensions, Druid? No? Well then don't be so sure you can't have 0 dimensions.

Personally, I think I'd have to agree that you can't go smaller than the planck length - inside the universe. Even a 'brane without any expanded dimensions would still have a size, even if that was less than 10^-33 cm, and it would be impossible to determine. But that's because you're trapped on the surface of the brane. You can't shrink the universe any smaller than that.

We can't measure anything smaller than that because of QM - but that doesn't mean a point doesn't exist. We can conceptualise it, even if we can't measure it.
