The best theory for time-travel, closed timelike loops, actually exist in the real cosmos, so time-travel should be possible. Right? Yet Paul Sutter's scratching his noggin over why the universe seemingly permits such journeys, he did the math, yet nobody's popped back to kill infant despots or game the lottery. That we know of... Far more breathless is Tristan Greene's admission, "This Amazing New Physics Theory Made Me Believe Time Travel Is Possible." Better yet, Tristan didn't hear about it from TikTok.
