“Is spacetime a fluid?” Leading physicists query

Summary of the spacetime issues discussed in this article. One can use photons and astronomical objects as test particles to measure spacetime over 22 orders of magnitude in scale, ranging from the cosmic horizon (probing the global topology of and curvature of space - top) to distant supernovae (giving evidence of dark energy) down to galaxies (giving evidence for dark matter), galactic nuclei and binary stellar systems (giving evidence for black holes)
