When asked, "If you could have any superpower, what would it be?" my answer was "I would slow down the speed of light so we could observe the effects of relativity, and then relativity would intuitively make sense to us, just like Newtonian physics does now."
Neither Alice nor Bob will let me borrow their spaceship that travels at 0.7 times the speed of light. Image sources here and here.
If you could have any nerdy superpower, what would it be?
