Hawkings: "cause comes before effect."
I wonder where this can be found in the Gemora?
Anyone want to give a try?
Hawking said once spaceships were built that could fly faster than the speed of light, a day on board would be equivalent to a year on Earth. That's because - according to Einstein - as objects accelerate through space, time slows down around them.
Moving backwards is impossible, Hawking says, because it "violates a fundamental rule that cause comes before effect"..
Once spaceships approached the speed of light, their crew would start skipping through Earth years on a daily basis, giving the human race a chance to start again.
“It would take six years at full power just to reach these speeds.
"After the first two years, it would reach half light speed and be far outside the solar system.
"After another two years, it would be traveling at 90 per cent of the speed of light.
“After another two years of full thrust, the ship would reach full speed, 98 per cent of the speed of light, and each day on the ship would be a year on Earth.
"At such speeds, a trip to the edge of the galaxy would take just 80 years for those on board.”
Oh, gosh, who would want to "Time Travel"?
You could never come back;
and if you could,
no one would know you,
no friends, no family,
and
just image the wrinkles on your face?

A comment on my own post.
On second thought, "cause before effect" could actually be the Creation of the World (Bereshit), when Hashem looked into the Torah and created the world.
And, Time Travel for frum Jews is the revisiting the actual Yom Tovim that we observe each year.
And what about Teshuva, when done accurately we return and turn old transgressions into future Mitzvos.
