Nothing stuck on our brane can exceed light’s limit as we see it. Change the temporal coordinates and it is a completely different reality, and I’m wondering how we are going to discern when/if we’ve tapped something over into those different temporal coordinates. THAT is what I wanted to write and ask Lisa, but I haven’t an address.

Now you've lost me completely. Relativity is complicated enough without adding branes and hyper dimensions. Hypothetical physics that exceeds our ability to test is just that.
