Ingvar: By the way, Mahin and I invented the concept of traveling into the past)))
Caroline: is it okay?
Ingvar: It comes from the Big Bang Theory. Do you know about anti-matter?
Caroline: I am not sure.
Ingvar: In general, in short, the Big Bang is cyclical, like the Mobius loop. The center of space-time is its epicenter. Accordingly, like the loop, the explosion (or more accurately the universe) has 2 twists. One in the positive part of the Descartes system of coordinates (expressed figuratively), the other in the negative. The point is that the negative twist (Anti-Universe) consists entirely of anti-matter and most likely has countermotive properties. And the fact that anti-matter is possible in our version of the universe also suggests the possibility of re-existence. That is, if we understand the mechanism of the formation of antimatter (and this is possible already in the process), then we will be able to transfer our matter to the negative loop of the loop, wire it along the countermotive stream and make its reverse transition in the past of our loop. The trick is that the traveler in time will evenly scatter the universe from anti-matter. Is it really funny?))
I just wrote all this and realized that the joke will probably seem ridiculous to you.
Caroline is a joke?
