Time Travel by the Numbers
So, you’ve got one of those time travel boxes from Primer, you go back in time, and now there’s two of you. But wait, what about mass conservation? The universe is now like 75kg more massive! We may be time-traveling, but we can’t go violating the rules willy-nilly.
My Caltech physicist buddy Chris figured out how much power those boxes would take to make a new 75kg person in 8 hours.
In units of Nagasaki explosions: 2.4 Hz.
