Positrons don't move backwards in time in any physical sense. Their mathematical representation is like an electron with a negative time coordinate but this is physically dubious because it fails in curved spacetimes. Electron-positron pairs are entangled because they are correlated by the process that created the pair. Entanglement is just a correlation, not some magical link.

"Smarter than you think" and "Similar to tiktok trends"...These are contradictory. Unless you thought our ancestors had undergone total lobotomies
