Discussion Overview

The discussion revolves around the nature of the center of the Milky Way Galaxy, specifically addressing the presence of a supermassive black hole (SMBH) and the visual representation of the galaxy's center. Participants explore the reasons behind the bright appearance of the center despite the presence of a black hole, touching on both observational aspects and theoretical concepts.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant notes that the center of the galaxy is depicted as a bright light due to the combined light of millions of stars, despite the presence of a supermassive black hole.
  • Another participant agrees and elaborates that the SMBH is extremely small compared to the surrounding stars, contributing to the brightness of the center.
  • A further contribution mentions that black holes are often surrounded by an accretion disk of superheated gas and dust, which also emits intense radiation, adding to the brightness observed.

Areas of Agreement / Disagreement

Participants generally agree on the reasons for the bright appearance of the galaxy's center, but the discussion remains open regarding the implications of these observations and the visual representations of black holes.

Contextual Notes

Some assumptions about visual perception and the scale of astronomical objects are present, but these are not fully explored or resolved in the discussion.

THE CENTER of The Milky Way Galaxy!

Supposedly, in the center of our galaxy (and in most galaxies, if I'm not mistaken) there is a super massive black hole.

In my mind I've always had the picture of a galaxy where there is a bright light in the center and lots of starts orbiting it... so if it's actually a black hole why is the center usually depicted as a bright light?

I guess it's because that's just the way they want to "draw" it, but I would like to know if there's another reason or perhaps if there's information I'm missing about this matter.

Compared to what you can see with the naked eye, the black hole is EXTREMELY small. When we see the center of the galaxy as a bright object, it's because of the combined light of millions and millions of stars. The SMBH (supermassive black hole) is only one point among millions, so the center still appears very bright.
 


Indeed, that makes a lot of sense, I'm surprised ( or rather, disappointed ) by the fact that I didn't think of it earlier.
Thank you for your help.
I'll send you a picture of my private toilet paper collection as a reward.

In addition to what Nabeshin said, black holes are often surrounded by an accretion disk of super heated gas and dust that is being swept up by the BH and radiates intensely, so even if we could zoom in on the black hole it's self it would still appear incredibly bright.
