Haha, that's pretty funny. Still, this depends on the definition of "birthday" and what frame the birthday is defined in. Say google was traveling at near light

Haha, that's pretty funny. Still, this depends on the definition of "birthday" and what frame the birthday is defined in. Say google was traveling at near lightspeed and time dilated 2x, so it's around Einstein's half birthday in their frame. If I had a wormhole that connects both frames, what is the correct solution?
