What Would You Do With A Time Machine?

While most people would use time machines to meet their ancestors or bet on sports, physicists have... different priorities. Imagine traveling through spacetime just to win scientific arguments. "Sorry Einstein, but quantum particles really can influence each other instantaneously across vast distances. Here's the Bell test results to prove it." Or saving Archimedes mid-eureka moment because his contributions to calculus were cut tragically short by a Roman soldier. And poor Aristotle getting schooled with Galileo's gravity experiments centuries before they happened. The ultimate "well, actually" move across the space-time continuum.
