B Gravitational Waves & Dark Matter: Is There a Connection?

AI Thread Summary
Gravitational waves and dark matter are connected through their interaction with gravity, as dark matter influences gravitational fields. However, dark matter does not produce detectable gravitational waves on its own, since it does not clump together like ordinary matter. Only extremely dense objects, such as black holes and neutron stars, generate detectable gravitational waves. While dark matter affects the geodesics of gravitational waves, it does not create its own waves. Overall, the relationship between gravitational waves and dark matter is limited to their shared gravitational interactions.

are gravitational waves somehow connected with dark matter??

Yes, in the way that dark matter interacts via gravity. In this case, dark matter would create gravitational waves were it to interact.
 
I wouldn't say gravitational waves are "connected" with dark matter beyond the fact that dark matter interacts via gravity. Other than that they have no connection to each other.

Yes in the sense that they interact with gravity. As for detectable wave? No. The dark matter will create geodesics that affect how we see the gravity waves, but it won't create it's own that are detectable. Only super dense objects like black holes or neutron stars produce gravitational waves that we can detect and dark matter doesn't clump together from what we can tell.

You seem to have a misconception that where gravity is concerned dark matter is different from ordinary matter. It is not.
 
https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.
Why was the Hubble constant assumed to be decreasing and slowing down (decelerating) the expansion rate of the Universe, while at the same time Dark Energy is presumably accelerating the expansion? And to thicken the plot. recent news from NASA indicates that the Hubble constant is now increasing. Can you clarify this enigma? Also., if the Hubble constant eventually decreases, why is there a lower limit to its value?
