moving the sun at rel+ speed

[It_is_i_wyatt]

i tried to figure out what RKE youd get from the sun (i used 1 m/s less than SoL) and when trying to translate the joules into higher measurements i ended up getting galaxy level, the number was somewhere in whatever's above tenafoe, but that cant be right, right?

 

[Setsuna_tenma]

No. You can't get galaxy level. It's probably 4B

 

[KLOL506]

Nope.

Beyond 93% SoL we only accept the KE value 4 times above the Newtonian KE value unless relativity is explicitly stated to take effect.

Even then, this still wouldn't be correct, the Lorentz factor formula would still bring it down to 4-B.

 

[It_is_i_wyatt]

didnt think so

also what does any of that mean

 

[XXKINGXX69]

Beyond 93% SoL we only accept the KE value 4 times above the Newtonian KE value unless relativity is explicitly stated to take effect.

Why? If something is above 0.93c wouldn't it just be relativistic by default?

No. It wildly inflates values to crazy levels because at this point your kinetic energy would be approaching infinity itself. There's also the Lorentz factor to take into account.

The Kinetic Energy Feats page clearly states the following:

• The relativistic kinetic energy value is only accepted up to 4 times the Newtonian value: The kinetic energy value calculated using the formula for relativistic kinetic energy is only accepted to the point where it is 4 times as high as the value of Newtonian kinetic energy. 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. Reason for this rule is that the relativistic kinetic energy diverges towards infinity for speeds approaching the speed of light. So to not get inflated extremely high results setting a threshold at 4 times the kinetic energy value was decided upon. An exception to this rule would be if a specific value is explicitly stated: For example, the Flash hitting with the force of a white dwarf star.

Why 4x?

Did you not read the bolded part in the paragraph?

Why 4x? Why not 2x? Or 3x?

Oh so its arbitrary, not surprised

I don't understand the rule, can you elaborate

It's called "KE rapidly approaches infinity at speeds beyond 93% c so a 4x Newtonian KE limit was chosen so as not to wildly inflate values, unless of course, explicit confirmation of relativistic KE being used is in the story"

Thats just rephrasing it

Like, if the feat is >93%c, we divide the result by four?

No.

If the feat is 93% c, you just do this: (0.5 * mass * velocity^2) * 4.

But if relativity is explicitly stated to be in effect, then you can continue using the relativistic calculator as usual like you normally would for feats involving speeds anywhere between 1-93% c.
