Crack smoker?? I've found the SUPPLIER!!!

sounds like a stupid joke to me with an underlying meaning ......the author of the ad obviously has no understanding of astrophysical or quantum theory.

a quantum wormhole is a molecular valence shell vaccum and an astro wormhole is the chemical change in mass decomposition either way it has little to nothing to do with gravity or negative gravity.

that plus negative gravity would not work as a "prop" does he even know what negative gravity is?
