I was aware that sonic booms happen when something moves faster than the speed of sound, and found out that Cherenkov radiation is emitted is when something moves faster than light, and then I found out that beings fighting at the speed of light would ignite the atmosphere, so I got curious and asked what would happen to onlookers to a fight happening at the speed of light.
Yeah we’d all die, onlookers and everyone else.
Back in my day we used to read XKCD to learn that throwing a baseball at relativistic speeds would vaporize the pitcher and batter.
I’m assuming the catcher would not have a good day either?

The stadium wouldn’t have a good day.
It’s worth pointing out that Cherenkov radiation occurs when something moves faster than light in a medium where light doesn’t travel at c. Nothing can travel faster than light in a vacuum without breaking all physics as we understand it.
Mass moving at the speed of light would mean everything we understand about physics is obsolete, so no one has any idea what would happen.
Mostly it would mean that we get half a season of shot-countershot internal monologue in midair bs for each kamehameha charge-up sequence.
Consulting with my own ass, none of that would happen, because of the Auth-Force. All fictional superheroes channel Auth-Force, which prevents consequences.
Real superheroes, of course, have to be careful.
Auth-force is another thing as well; how do they decide which laws of physics they’ll break? At certain points they’ll be like ‘radiation makes superheroes’ but then be like ‘pffft, going faster than light wouldn’t send you back in time, that’s just silly’
Kryptonians have a force field around them to prevent such things (also DC physics is different in that there are different fundamental forces.) While the saiyans can fight very fast, faster than a human can follow, they do not fight at the speed of light. And lastly viltrumites aren’t real.

I was curious about how speed can be measured (in these fictional settings) so as to explain how it’s calculated that they’re moving FTL, and the explanation was that they can travel between planets and moons faster than light travels; as for whether or not they’re FIGHTING at these speeds, admittedly there’s no way of proving this (unless there’s a principle you could see at play), additionally if they move faster than light, how can they see each other as they fight; even if they could sense one another, they can’t sense androids and they fight those guys in the main storyline

Ah, I actually didn’t know this one (I’ve never been a heavy DC reader)
(also DC physics is different in that there are different fundamental forces.)
Admittedly this is also true, as the speed force is also a thing that exists as a fundamental force in the DC-verse
To my knowledge, I do not believe anyone flies between planets without the aid of a some sort of spaceship in Dragon Ball (not counting instant transmission, because that’s not moving). So while there is FTL travel in universe, no one can achieve it without a machine and they wouldn’t be fighting at that speed.

easy fix, just fight at 0.999999 the speed of light
The fuck is a viltrumite?
Kryptonians but from Invincible (the comic/show)
Does goku clock the speed of light? I know he can teleport, and fly super sonic speeds
I’ve wondered myself how we’re supposed to know that these people can fly faster than light, and one method of showing this was showing how fast they can fly in outer space; a journey that takes light years would take these characters weeks
I guess that makes sense, you just never really see any of the cast flying in space, right? At least I don’t remember
I think they used a spaceship when they went to Namek
They did! I do remember in movie 3 at the end there’s a fight in space though.
