They would see that they got a reply immediately, and would always remember that they had a reply.

> I’ve heard that used as an explanation for why we don’t see time travelers. Every time someone comes back they split off a new alternate universe; so if a million time travelers show up at an important historical event like the Crucifixion there’s not a mob of a million time travelers, there’s a million new universes with one time traveler each. Most of whom may well try to blend in, making it even harder to find evidence.

Eh, my theory is that the angels beat any time travelers back with sticks and/or smote them. Thus, they never got close enough (save perhaps 3 wise ones ;)), to make it into the history books…
