I Are dark matter and dark energy caused by same phenomenon?

AI Thread Summary
The discussion explores the idea that particles popping in and out of 'empty' space could account for both the gravitational forces holding galaxies together and the expansion of space. The hypothesis suggests that these particles, due to their mass, might create additional gravity and cause space to expand upon their entry. However, the conversation quickly shifts to the notion that dark energy and dark matter are unrelated phenomena. Participants emphasize that personal theories cannot be shared according to forum guidelines. The thread ultimately concludes with a reminder of the limits of speculation in scientific discussions.

TL;DR Summary
After watching a two-part program Everything/Nothing, a thought occurred to me when the discussion turned to particles popping in and out of 'empty' space.
After watching a two-part program Everything/Nothing, a thought occurred to me when the discussion turned to particles popping in and out of 'empty' space. Could these particles be numerous enough in the vast space between stars to be responsible for the gravity holding stars together in galaxies and at the same time be responsible for the expansion of space? They have mass, which would explain the extra gravity if enough of these particles are present at any given time. Particles need space to exist, but by popping into our space, do they cause an expansion of it upon entering that doesn't contract as they exit for some unknown reason? That would explain the expansion of space.

Dark energy and dark matter are completely unrelated.
 
I thought so until that popped into my head. What if I'm on the right track? There's a lot we don't know about reality.
 
You are not on the right track. Yes, there are things nobody knows. No, you are not going to solve those issues after watching a popular scientific account.

Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
