sry mikeymike,
Got to pull you up there...
In fact matter can be created from `nothing`, er as in virtual particles (which are as real a `normal` particles), but the trick is to do it in as small amount of time possible...
The electricity in all the wires that have ever `flowed`, for example, were/are all virtual particles. (Each electron, is created and destroyed to form the illusion that a particle is moving along the wire.)
[I won’t go into the details of how black holes radiated energy with the creation/use of virtual particles here...]
[Er, nor quantum tunneling]
