In this house we obey the law of general relativity and forces over c⁵/4G will not be tolerated.

But could someone please explain a little? If I have a widget that does c⁵/4G watts of work when I turn it on, what happens when I turn on a second one? Nothing? Distance between widgets doesn't matter?

If you try to produce more power than c⁵/4G at a single point, a black hole horizon appears and will make exceeding the limit impossible.

So that's a limit on power per cubic planck, and you can do it again if you shift one planck over?

[PrettyPebble]

Maybe you have to shift a bit more ...
