Discussion Overview

The discussion explores the relationship between atoms and the universe, questioning whether the universe can be viewed as an enlarged model of an atom. Participants examine similarities and dissimilarities between the two, as well as the existence of multiverse or meta-verse concepts.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions if the universe is an enlarged model of an atom and asks for similarities and dissimilarities between them.
  • Another participant notes that while large objects in the universe attract, some particles in an atom attract while others repel.
  • A different participant raises a question about the expansion of the universe in the absence of repulsive forces.
  • One participant suggests that an initial force or the expansion of space itself could explain the universe's expansion.
  • Another participant expresses uncertainty about cosmologists' understanding of the reasons behind the universe's expansion.
  • One participant firmly states that there are no similarities or dissimilarities between an atom and the universe, and claims there is no evidence for multiverse or meta-verse concepts.
  • Another participant agrees that there is significant debate regarding the universe's expansion, mentioning dark energy and dark matter as factors, while suggesting a potential connection to general relativity.
  • Some participants challenge the assertion that there are no similarities or dissimilarities, arguing that there are indeed many, although not in the context of the universe being a scaled-up atom.
  • A later reply discusses the complexities of dark matter and its implications for understanding the universe's structure and expansion.

Areas of Agreement / Disagreement

Participants express disagreement regarding the existence of similarities and dissimilarities between atoms and the universe. Some assert there are none, while others argue that there are indeed many. The discussion on the universe's expansion and the role of dark energy and dark matter remains unresolved, with multiple competing views presented.

Contextual Notes

Participants highlight the uncertainty surrounding cosmological concepts, particularly regarding the reasons for the universe's expansion and the nature of dark energy and dark matter. There are also differing interpretations of the relationship between atomic and cosmic structures.

Dear all, ma questions is what is the relation between atom and the universe? Is universe an enlarge model of an atom? What are the similarities and dissimilarities between an atom and the universe? Is there any evidence of the existence of multiverse or meta-verse?
 
Physics news on Phys.org
Planets, stars, asteroids, gas clouds, and all large objects within the universe attract. In an atom some particles attract while others repel.
 
But if there is no repulsive force in the universe then how universe is expanding?
 
Good question. I assume an initial force, or space itself is expanding.
 
Don't know about this thing. But i think cosmologist are not sure about the exact reason behind it.

No.

What are the similarities and dissimilarities between an atom and the universe?
None.

Is there any evidence of the existence of multiverse or meta-verse?
Evidence? None. Some rough ideas, but no real data.
 
Correct. There is much debate about how the universe is expanding faster than it should, there is also debate about how it is slowing in expansion faster than it should. So they call it dark energy and dark matter respectively.

I think it is neither and will be found to be a more elegant form of general relativity.

None.

How can there be no similarities or dissimilarities? There are plenty of similarities and dissimilarities.

Not along the lines the OP was contemplating, like the universe being a scaled up atom. I meant "no similarities", not "neither similar nor dissimilar" :smile: On the other hand, the latter is the kind of thing you run into when discussing atoms.

Perhaps this should be moved to another forum. But, while the accelerating expansion is still mostly a mystery and furthermore lends itself to a global over-all effect, the catalog of unseen attractive things contains a large part of "cold" dark matter which exists as clouds of unseen gravitational source. Irregular clouds don't lend themselves to some change in the rules of what holds a galaxy together.
