Ever wonder why we can’t just hop in a time machine and visit the past? Turns out, physics says nope! Even though the math behind time is mostly reversible, the real world is ruled by entropy—aka, things get messier, not neater. That’s why eggs don’t unbreak and why your coffee never reheats itself. The universe is basically set up to keep us moving forward, not backward, no matter how many movies say otherwise. #Science #TimeTravel #Physics
