Black Holes and Gravity … the Rest of the Story?

Black holes are observed to “gobble” stars, planets, etc. Once pulled into a black hole, the material objects cannot exit it owing to its immense gravitational grip.

In galaxies there is a constant flux of material (sub-light speed) particles too small to be detected by telescopes, and these particles no doubt also add to the total of absorbed matter. All absorbed matter adds to the hole’s gravitational strength, and the strength of the hole’s gravity consequently increases with time.

It is believed that a hole also captures incident radiation. (Hence its black color.) According to gravitomagnetic theory this radiation adds to the hole’s gravity. That is, according to the theory photons have gravitational fields quite as material particles do. Since the flux of radiation in the Universe exists everywhere … even in inter-galactic spaces where the flux of material particles is negligible …, the absorption of photons may result in even more rapid increases in a hole’s gravity than does the absorption of sub-light speed matter.
