A Quantum Constraint for the Physical Viability of Classical Traversable Lorentzian Wormholes

Authors: Kamal K. Nandi, Yuan-Zhong Zhang, Nail G. Migranov

The physical viability of classical wormholes can be ascertained by computing if the total volume of exotic matter needed to maintain the wormhole is finite. Using this value as the lower bound to the quantum ANEC integral, we confirm that only Planck size wormholes can be supported by the massless quantum Klein-Gordon field. Some known wormholes seem to be physically unrealistic.

The Planck length is the scale at which classical ideas about gravity and space-time cease to be valid, and quantum effects dominate. This is the ‘quantum of length’, the smallest measurement of length with any meaning.

And roughly equal to 1.6 x 10 to the -35 meters or about 10 to the minus 20 times the size of a proton.

Pretty useless, and that's all this paper wants us to have.
This is more like it!

Can't we please have our wormholes?
