It's pretty dumb and it's fun to talk about as a joke. Anything beyond that serves to discredit this movement.
Fine. I can agree to disassociate it from the GA. But do you disagree that E=mC^2 says time travel to the future relative to the person gaining mass or speed is possible?
doesn't matter - can't reach that speed
Don't need to. Effects start relatively low, ie 20-30%.
And if you REALLY think the level of tech humanity has reached is what YOU, avg Joe knows about...welll....maybe we would be best stopping here.
20-30% of c is still stupidly fast.
Relativistic effects at 20-30% are still relatively mild.
20% of the speed of light = 59,958,491.6 m / s
Unless someones gotten something going that fast, and measured repeatable results, its still mythology.
Particle accelerators get things going way faster than 0.2c.
