Discussion Overview

The discussion revolves around the nature of the universe's parameters, particularly in relation to hidden variables in quantum mechanics, and the roles of dark energy, dark matter, and microscopic black holes. Participants explore theoretical implications and interpretations of these concepts.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions whether the universe's parameters are quantum mechanically optimal for hidden variables and if dark energy, dark matter, and microscopic black holes are part of non-observable systems.
  • Another participant argues that the usual hidden variables in quantum mechanics have been shown to be inconsistent with experimental observations, suggesting that hidden variables do not exist.
  • There are differing interpretations of dark energy, with some participants proposing it could be an exotic form of energy, while others suggest it may be energy that has not yet been accounted for.
  • Some participants mention the concept of virtual particles in relation to dark energy.
  • A quoted source discusses Einstein's cosmological constant and its implications for dark energy, noting the historical context and ongoing uncertainties regarding its nature and effects on the universe's expansion.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the existence and nature of hidden variables, as well as differing interpretations of dark energy and its implications. The discussion remains unresolved with no consensus reached.

Contextual Notes

Participants highlight the limitations of current understanding regarding dark energy and its relationship to the universe's expansion, as well as the dependence on various interpretations of quantum mechanics and cosmological theories.

quantum Mechanically optimal for Hidden Variables? and are Microscopic Blackholes, Dark Energy, Dark Matter Part of Hidden Variable( Non Observable) Systems?
 
Physics news on Phys.org
If by hidden variables you mean the usual hidden variables referred to in QM, then thoose hidden variables has been shown inconsistent with experimental observations. So there are no hidden variables. I don't know what all that Dark energy/matter is, I've seen different interpretation as to what "dark" energy means. Some seems to think its some exotic form of energy other seems to think its just usual energy which we haven't accounted for yet.
 
And some think of virtual particles.

What is Dark Energy?

by NASA Goddard Space Flight Center and ScienceIQ.com

Because he originally thought the Universe was static, Einstein conjectured that even the emptiest possible space, devoid of matter and radiation, might still have a dark energy, which he called a 'Cosmological Constant.' When Edwin Hubble discovered the expansion of the Universe, Einstein rejected his own idea, calling it his greatest blunder. As Richard Feynman and others developed the quantum theory of matter, they realized that 'empty space' was full of temporary ('virtual') particles continually forming and destroying themselves. Physicists began to suspect that indeed the vacuum ought to have a dark form of energy, but they could not predict its magnitude.
Through recent measurements of the expansion of the Universe, astronomers have discovered that Einstein's 'blunder' was not a blunder: some form of dark energy does indeed appear to dominate the total mass-energy content of the Universe, and its weird repulsive gravity is pulling the Universe apart. We still do not know whether or how the highly accelerated expansion in the early Universe (inflation) and the current accelerated expansion (due to dark energy) are related.

A Beyond Einstein mission will measure the expansion accurately enough to learn whether this energy is a constant property of empty space (as Einstein conjectured), or whether it shows signs of the richer structure that is possible in modern unified theories of the forces of nature.
