Light Speed kinetic Energy

[Tankirbmon]

Looking at the kinetic energy Page it's rules don't ban kinetic energy for objects moving at exactly the speed of light. Only FTL speeds

It says to take 4 times the results of the normal kinetic energy formula for speeds above 93% sol but below ftl. So light speed would be 1.7975e+17J/Kg

Is this correct?

At lightspeed, Kinetic Energy becomes infinite due to relativity.

Yes I know this, but the rules of the page don't seem stop you from usinv the same method described for 93-99% the speed of light for 100% the speed of light.

It basically says for 93% to NOT FTL using 4 times the standard formula, which would include the normal speed of light

That method is only for speed below the speed of light. You can't use it to calc the KE of things moving at exactly lightspeed.

I would have assumed that. But the page itself says

"That is the case, if the speed of the moving object is above 93% of the speed of light. For kinetic energy values above that, which are not faster than light, 4 times the kinetic energy value should be taken"

It explicitly only bans you from using it for FTL speeds not for speed of light speeds. Is this a mistake on the pages part and need fixing?

I think it was just supposed to be intuited. I always assumed lightspeed was off the table.
