How fast is near light speed?

[Fastestthingalive50]

I’ve been doing a kinetic energy calc for someone moving at speeds “near light”, and stuff like that, and it got me thinking: what percentage of lightspeed do we use for statements like that?

Relativistic+, or more specifically, I'm pretty sure it's best to use 90 percent Lighstpeed

Yeah I think we assume it is 90% or something, or maybe the limit of like 93%

I'm not a big fan of using "Near light speed" as a justification for Relativistic+ and feel like it's prone to hyperbole unless there's more in depth context. But some verses said baseline Relativistic while others said Relativistic+ and the like.

I mean, I guess it's a case by case basis. It's better if you send where it's from so we can whether or not it's valid in this case

Near is super vague imo, I think 51% should be the bare minimum since you are closer to it than to 0%

 

[Hasty12345]

To me, "near" would imply closer to light speed than not, so 0.5c would be a safe minimum if you take the statement as literal. But ofc, it would have to be consistent with prior feats etc etc

I've seen 75% being used but It could also be 90%
