paraphrased: "nothing == everything"

you are an idiot.

are you mad??? if light had infinite mass, then every torch would act like the Half-Life 2 gravity gun.

no... if you turned the torch on, you would be instantly destroyed.

there is no such thing as "infinite" in reality - every case where "infinity" turns up is a case where the existing maths is not quite up to describing reality.

silly me. picture in article doesn't look remotely VTOL.

but in that case, i don't really see the point - if it's not a VTOL, it would need to take off and land at airports, in which case why not just use an airplane?

are these things not VTOLs? in which case, why would they need a runway?
