Discussion Overview

The discussion revolves around the potential fate of the universe, specifically the idea that it may eventually collapse into a single point due to the gravitational effects of supermassive black holes. Participants explore concepts related to cosmic expansion, the Big Bounce theory, and the nature of black holes in relation to gravitational attraction.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants propose that the universe could eventually become dominated by supermassive black holes, leading to a collapse into a single point, potentially resulting in another big bang.
  • Others argue that black holes do not have a unique "sucky-power" and do not attract each other more than ordinary stars or galaxies, suggesting that any collapse would be a general phenomenon rather than caused specifically by black holes.
  • One participant suggests that the current acceleration of the universe's expansion could be viewed as a temporary phase, with the possibility of deceleration and eventual collapse as gravitational forces overcome the expansion.
  • Another participant references the Big Bounce theory as a legitimate scientific concept being investigated by cosmologists, indicating that similar ideas have been considered in the scientific community.
  • There is a challenge regarding the validity of a hypothetical example involving "clustered circular ice wasps," which appears to be a non-serious or random thought experiment.
  • Some participants express uncertainty about whether their ideas are novel or if they have already been explored in scientific literature.

Areas of Agreement / Disagreement

Participants express a range of views on the fate of the universe, with no clear consensus reached. There are competing models and interpretations regarding the role of black holes and the nature of cosmic expansion.

Contextual Notes

Participants acknowledge that stellar events may not follow the same patterns as smaller objects, but they speculate on the applicability of certain theories across scales. There is also mention of historical expectations in cosmology that have not aligned with current observations.

Who May Find This Useful

This discussion may be of interest to those exploring cosmological theories, the nature of black holes, and the dynamics of cosmic expansion and contraction.

Hello,

Is it possible for this to be... ?

Could it be that the whole universe will eventually become so full of super massive black holes, that they all draw in together under their combined gravity, and the universe will eventually collapse into a single point, where another big bang occurs.

And the reason for our universe expanding and accelerating at this point in time, is perhaps because the universe is still young in its life, where as like any explosion, the forces are accelerating during the early stages of the bang.


Have a good weekend!

black holes have no "sucky-power" …

they don't attract each other any more than ordinary stars or galaxies do

if there is eventually a general collapse, with everything "drawing in together under their combined gravity", then of course the black holes will also draw together with everything else, and may swallow up everything else,

but that will be a result of the general collapse, not a cause of it :smile:
 
At present it appears that the expansion of the universe is accelerating, the opposite effect of what was asked.
 
Perhaps the accelerating can be explained such that, the big bang explosion is still in its infancy, and that the acceleration will taper off in time, start decelerating, and finally stop at which point the combined mass and gravitational pull of every and all heavenly bodies has overcome the waning force of the big bang, and finally start reversing... The universe collapse...

I am in a sense treating such an epic event with the same sort of theories that apply to small things and objects, and I am aware that stellar events don't follow the same patterns, but... perhaps they do?

I guess what I am trying to find out, is that minds have already considered these options right? I didn't just have some eureka moment where as I will be in science journals the world over praised for my day dreaming?
 
AN exmaple of someone being a RANDOM thinker would be if someone posed the question:

"How do clustered circular ice wasps circumnavigate the cosmic background radiation slip stream"?

Is this random enough?
 
Ah thanks for info! No doubt in the future I will form some other idea, find out how to explain it, then come back here :p

Cheers
 
Cite an example of your 'clustered circular ice wasps' - a published paper reference would be preferred.

In fact, a cosmic decceleration was what astronomers/cosmologists thought they would observe in the 1990s when supernovae were first used at large enough distances and in high enough numbers to probe the expansion history of the Universe. What they observed was the opposite-- the expansion is accelerating.

Do you have the time?

Sure, show me how you keep moving the goalposts.

You mean you don't know how it's done?
