Discussion Overview

The discussion revolves around the hypothesis that black holes could be responsible for the creation of galaxies, questioning the traditional understanding of the Big Bang and proposing that each galaxy may have originated from its own "mini" Big Bang associated with its central black hole. The conversation touches on theoretical implications, the nature of black holes, and their gravitational effects on surrounding matter.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant suggests that if black holes can distort known laws of physics, they might have the potential to create matter, leading to the idea of multiple smaller Big Bangs occurring within individual galaxies.
  • Another participant notes the incompatibility of general relativity and quantum theory in describing black holes but argues that this does not imply that black holes can create matter.
  • Some participants assert that black holes are formed from supernovae and are born out of stars, indicating that they do not create galaxies but rather influence the orbits of surrounding stars and gas.
  • One participant challenges the claim that black holes from supernovae can pull stars and gas from the surrounding universe to form galaxies, stating that their gravitational effects are limited to the central parts of galaxies.
  • There is mention of the possibility that stellar mass black holes can accrete matter to form supermassive black holes, suggesting a different mechanism of growth rather than creation.

Areas of Agreement / Disagreement

Participants express differing views on the role of black holes in galaxy formation, with some supporting the idea that black holes could create galaxies and others firmly stating that black holes are formed from stars and do not create galaxies in the proposed manner. The discussion remains unresolved with multiple competing views present.

Contextual Notes

Participants highlight limitations in current understanding, particularly regarding the interaction of general relativity and quantum mechanics in black hole physics, and the specific mechanisms by which black holes influence their galactic environments.

I had a thought the other night when I heard that there is a super massive black hole at the center of every galaxy. My thought was is it possible that the big bang did not happen once trillions of years ago? Is it possible that every galaxy was created by its individual big bang from the black hole that holds it together? If you consider that the core of the black hole seemingly defys all known laws of physics or distorts them all then is it not reasonable to assume it has the potential to create matter. If the beginning of the black hole were to spin at what can only be described as astronomical speeds and were the single strongest magnet mankind could possibly envision and also if the black hole were emitting matter then wouldn't it magnetise all matter and send it into an orbit. If this is so then the universe was not created with one single big bang but trillions or possibly more smaller big bangs which would still be happening to this day.

General relativity and quantum theory are incompatible in trying to describe what happens inside a black hole. However creating matter doesn't come out of the existence of this problem.
 
Sure its possible, but its pretty well established that black holes are formed from certain types of Supernova, which means they are born out of stars. These black holes in turn, have such strong gravity that they pull surrounding stars and gas into orbits around them, thus they create their own galaxy.

This is absolutely untrue. In fact the supermassive BHs gravity has only a measurable effect on the very central parts of a galaxy. It is certainly untrue that a black hole from a supernovae pulls stars and gas from the surrounding universe to form a galaxy. See http://www.universetoday.com/am/publish/early_black_holes_grew_quickly.html" for a brief explanation on the formation of supermassive black holes.

However, it may be true that stellar mass black holes accrete matter and form a super massive black hole.
