Finally. Thank you. Someone thinking past the punch bowl.
Forget paradoxes, pathogens are the real problem. You don’t need to step on a butterfly to wreck the timeline; you just need a 21st-century rhinovirus and a handshake. Entire villages, gone. History rewritten by a sneeze.
Any responsible time traveler would be sealed head to toe. No exposed skin, no shared air, no hors d’oeuvres. Certainly no cake. You don’t know what yeast does to medieval Europe when it’s had a few centuries of upgrades.






That ‘everything’s moving’ argument is a convenient shutdown, not a dead end. We already track motion precisely, GPS corrects for relativity every second. That means relative positioning isn’t unsolved; it’s restricted.
You wouldn’t target a spot in space. You’d target a worldline, like Earth’s continuous path through spacetime. Same path, different point.
Saying you’d end up in empty space assumes a cartoon machine that only changes the date. A real device moves you along spacetime itself.
So when people say time travel is impossible because there’s no reference frame, what they really mean is: you don’t have access to the frame that works. Not impossible. Classified.
