This wasn't based on a physical theory, just empiry and material science.

People said many things, but I wonder why you keep mentioning that
"people said" thing. It bears no relevance to argumentation. People
also said witches don't float on water and the brain is an organ for
cooling of the blood, and that mice are generated spontaneously from
straw and dirty cloth, and that stones can't fall from the skies.

There is no debate. You can't signal faster than the speed of light in
vacuum. If you've read more than that into it you fell into the trap
of wishful thinking.

For example? Do you have a physical theory to go with that one?
This isn't alt.gee.whiz.wouldn't.it.be.nice.if.extropians, btw.

1) No evidence for such physics
2) No evidence for anybody using such technology

I would be foolish to assume that our current physics is accurate. In
fact we know it isn't. However, I would be doubly foolish to step
beyond the known laws, and start extrapolating. There are a lot of
these "could be's", way more than there are neurons in my brain. I
prefer to engage them for more fruitful speculations, e.g. what's for

The Singularity is a testable hypothesis about future civilisatory
development. We will know it when we get there, and not before.

Then why do you keep talking about things beyond the predictability

Yeah, the truth is out there, somewhere, along with the Moon made from
green cheese and the X files.
