RE: A dark side brighter than expected - a reappraisal of composite dark matter
You are viewing a single comment's thread:
I've still got a lot of work to do to understand physics at this level.
I'm reading an Einstein biography. He rejected the concept of the ether, but later thought that space had to have properties. Would dark matter be related to these postulated properties?

Hi!
Dark matter is part of what is coined the Standard Model of cosmology. Therefore, it impacts the properties of the universe. But this is not the only unknown ingredient. There is also dark energy that is itself responsible for the expansion of the universe. And the two can be fully unrelated, or related (there are some constructions where they are). In short: we don't know (which is the reason why it is interesting)
I hope my answer clarified a bit. Otherwise, feel free to come back to me.
Cheers!
Thanks, your clarification helped a lot!
