A wonderful aspect of using math to describe physics is the things admitted as possibly by the math might describe things possible in the physical reality but are very hard to observe given our frame of reference. The fact we’ve really found absolutely nothing observable that contradicts going backwards in time hints that it might in fact be possible under the right conditions. Our sense from our frame of reference that it isn’t doesn’t prove anything, just that we have only observed an asymmetry so far. Sabine made a great episode on this recently, fwiw, and it’s worth watching if the subject interests you. https://youtu.be/4ICIObFtWjM?si=XJ2t0P_I6XCWTl1Q |
