Earlier quoted context omitted.

Time travel back into the past is understood to be impossible.

The math say time travel is possible, but the energy required would consume the universe, depending on what paper your read. There is no reason math wise the arrow of time only goes in one direction.

Erm, there is something fundental discovered in thermodynamics that we call entropy. Energy only flows in one direction and time as well.

If you do not work on an important problem, it's unlikely you'll do important work. It's perfectly obvious. Great scientists have thought through, in a careful way, a number of important problems in their field, and they keep an eye on wondering how to attack them. Let me warn you, `important problem' must be phrased carefully. The three outstanding problems in physics, in a certain sense, were never worked on while…

Time travel back into the past is understood to be impossible.

Yes, a more in depth analysis of this can be found at https://en.wikipedia.org/wiki/No-communication_theorem

So you know, I in general try not to pull comments out of thin air.

Etc..

The MATH allows it.

I took a look and found plenty of semi-insulators out there, but no peep about what association those materials have to do with taming the gravitational force - or am I missing the point?

To really be able to manipulate gravity, you would also need to manipulate mass, and so far nuclear is the only way I know of, in which we do that, but uhh.. I don't think we'll get anti gravity until we can control mini stars... Little nuclear engines.

Maybe it means a gravitational insulator?

Certain kinds of it. Time travel to the past in a parallel universe at least doesn't cause any logical problems ('paradoxes') to arise. https://en.wikipedia.org/wiki/Time_travel#Interacting_many-w...

And where would the information about parallel universes be contained?

i would figure in that parallel universe lol, or if you want to be more general, in some overarching metaversal container leading out to the omniverse at greeter degrees. but that's just me ¯\_(ツ)_/¯
