This question is very thoughtprovoking.
I agree. I imagine it would take a while for anything to really happen because of politics and cost
Maybe not, though. I'm thinking historically Many groundbreaking technologies shocked the world before governments had a chance to regulate them. But I think that would depend upon whether the discovery was made by private individuals, or by some organization like NASA. I think it would revolutionize how we thought about space and time.
I agree with that. It would allow us to further explore the relationship between speed and time.
