I think the issue is that seeing something from the past is not the same as time travel. If I yell, then travel faster than sound, then stop, I'll hear my previous yell, but so what? It's not like I can run back faster than sound and stop myself from yelling.
- maxerickson 4y agoYeah, if you use a false analogy it doesn't make any sense. Traveling faster than light isn't the same as (or rather, wouldn't be similar to) traveling faster than sound.
- BobbyJo 4y agoYes, and that is, specifically, the part that is not apparent. What makes it not the same other than one being light/faster and the other sound/slower?
