A black hole is the ultimate manifestation of a region of strong gravity. The pull of gravity in a black hole is so strong that even light cannot escape from it and time stands still.

The one aspect of the star-studded night sky which impresses the casual observer most is its tranquility...

It was around dusk when my companion and I noticed the position of sun closer to the west horizon, and the sun was going up.

The Gran Sasso results could be seen as tentatively offering support for the big bang theory – if we could find a way to test that they are indeed travelling backwards in time.

I have not been able to relate the idea to the 'faster than light' neutrinos since there are no causality checks to decide if they are travelling in the past.

Space-time in an expanding universe changes over time, so the full quantum description of a neutrino. in that type of universe is different in the past and the future. Neutrinos would behave in both expanding and unchanging "steady state" universes.

Found that in a universe that is expanding after a big bang event, neutrinos would turn up at a detector before they were emitted. Only future-going neutrinos were possible in the Steady state cosmology while the ever-expanding big bang models gave neutrinos travelling into Steady State theory to the past.
