comment Do gravitational waves affect light?
Instead of gravity "bending light," it's more accurate to say that gravity bends spacetime, and light simply follows a geodesic path along the bends. Thinking of it that way, it makes sense that there should be a "shimmering" effect when light passes near a source of gravitational waves. The difficulty is that this effect is extremely small, and we're only now starting to develop the technology with enough resolution to detect it.

revised could you avoid spaghettification in a black hole if the object thrown in was spun around at an uncountably or countably infinite speed?
to the point.

Well sure, if something is spinning faster than light (which would be required in this case), then it could avoid being crushed by the singularity of the black hole. But this would simply be trading one physical impossibility for another.

comment How can space and time occur spontaneously?
Having read the book, I can say that Krauss explains everything fairly thoroughly. Can you provide the actual portion of the book that confuses you?

It does. It does. There doesn't.

comment Antimatter transmission
It's already possible to transmit electricity without any loss: en.wikipedia.org/wiki/Superconductivity. I suggest you focus your research efforts on room-temperature superconductors. Your antimatter won't travel very far unless it's in a vacuum.

comment If an object's motion through space-time at speed $c$ corresponds to ageing, would cooling it down to slow ageing mean it doesn't move at $c$?
A particle traveling at $c$ doesn't experience any proper time, so the idea of "aging" doesn't apply to it...
