Probing spacetime foam with extragalactic sources
W. A. Christiansen, Y. Jack Ng, H. van Dam
Due to quantum fluctuations, spacetime is probably ``foamy'' on very small scales. We propose to detect this texture of spacetime foam by looking for core-halo structures in the im…

Probing Planck-scale Physics with Extragalactic Sources?
Y. Jack Ng, W. A. Christiansen, H. van Dam
At Planck-scale, spacetime is "foamy" due to quantum fluctuations predicted by quantum gravity. Here we consider the possibility of using spacetime foam-induced phase incoherence o…
