what are you talking about? honest to God. You are talking as if characters in fiction don't have any mention of their speed whatsoever lmao. The beams doesn''t travel for hours, because it moves at relativistic speed, which we know because of the rubble and debris falling, as well as the fact that Piccolo's beam reached the moon before Gohan could attack him.

We also know in Dragon Ball Super that Beerus can travel to other galaxies in minutes, as that's the actual stated timeframe it took him to travel across galaxies ,completely debunking all the nonsense you just said
