Could Dark Matter be Time itself?

Click For Summary

Discussion Overview

The discussion explores the hypothesis that dark matter could be conceptualized as time itself, touching on various aspects of physics, including the behavior of stars in galaxies, the acceleration of the universe's expansion, and the nature of dark matter's interaction with forces.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant suggests that the velocity of stars around galaxies could relate to a dark matter halo, potentially influenced by the mass distribution within galaxies.
  • The same participant connects the idea of dark matter to the acceleration of the universe's expansion, proposing that this acceleration may not be slowing down.
  • Another point raised is that dark matter does not interact with known forces, which could support the hypothesis.
  • The participant speculates that an increase in time could correlate with an increase in energy, suggesting a possible link between time and dark matter.
  • One participant challenges the initial hypothesis, stating that it does not make sense.
  • Another participant defends the idea by referencing the concept of spacetime introduced by Einstein, indicating a historical context for understanding time.
  • A later reply warns against relying on popular science sources for understanding complex scientific concepts and suggests seeking peer-reviewed references instead.

Areas of Agreement / Disagreement

Participants express disagreement regarding the validity of the hypothesis that dark matter could be time. While some engage with the idea, others outright reject it, leading to an unresolved discussion.

Contextual Notes

The discussion includes references to popular science materials, which some participants caution against, indicating a potential limitation in the depth of understanding presented.

As title really, just an idea I had from various videos and articles I've read as an enthusiast of all things physics.

Some supporting sentences from my somewhat ignorant but perhaps not-entirely-wrong thinking:

- The velocity of stars around the periphery of galaxies, I've heard of a theory where matter has a halo of dark matter, and perhaps due to the greater mass at the centre of the galaxy this could apply

- The acceleration of the expanding universe and the reason why expansion is increasing, and not slowing down

- It does not interact with any of the forces

- Perhaps it can still account for its theoretical share of energy in the universe because more time = more work?

That doesn't even make any sense.
 
Why not? I'm aware that since Einstein that space and time is essentially considered as spacetime, but beforehand time did indeed make some kind of sense to us mortals.

Please do not try to learn actual science from pop science videos and articles. We have a policy about acceptable references at PF for a reason.

If you want to find some good textbooks or peer-reviewed references about dark matter, please start a new thread to ask for them. This thread is closed.
