They flew atomic clocks on separate commercial airplanes that traveled around the world in opposite directions. This experimental setup allowed them to compare the elapsed time of one clock with respect to another.

The simplest answer is that time travel cannot be possible because if it was, we would already be doing it. One can argue that it is forbidden by the laws of physics, like the second …Indeed, backward time travel, while theoretically possible, is far trickier and would involve black holes and “tunable wormholes” and more energy than a kindergarten class on a sugar binge ...Jun 6, 2022 · Traveling into the future is possible, but scientists do not know if backward time travel is possible.
