I have degrees in Physics and Mathematics and I’m here to tell you that you didn’t learn enough. Time and space can be bent (any gravity well). Worm holes are nearly a mathematical certainty. You don’t have to travel faster than the speed of light to travel light years in short time spans.
If you pursued those disciplines, math and physics, and you harbor the notion inter stellar travel by humans is possible than you are seriously deluded FRiend.
