Ok, I'd be interested in the math on that one. Any chance you would know where you saw that?

I'm just curious on the calculations (if they are sharing).

True.

But at least this is a problem we can address with current technology and scientific understanding.

I don't have to generate matter with a negative mass to make food last longer...

Sadly, agreed...

The Alc. tensor is the solution to a formulation that doesn't exist (currently). And the implication of it would be rather...problemsome.

It would act a bit like a DF from starfire. In that objects that entered or existed in the area of 'altered spacetime' would be subjected to accelerations greater than c, they would by (ok, most theoretical) definition be converted from 'matter' to 'energy'. Of simply become naked singularities (which would be the same thing, just contained within an event horizon...).

Alc metrics are fun thought experiments. But the actual 'execution' of one would (probably) be impossible. At least until someone can isolate substantial quantities of matter with a negative mass.
