Dark Matter Discovery Announced by Nasa

Q relayed some information between B and Sean, so I thought I would follow up.

One thing that is forefront of my mind here, is lensing, and how photonic expression of the event is govern by the inclinations of gravity. Held to the event. Evidence of this event is then "scattered" throughout the universe?

So how shall we look "back to a time" and then not wonder how we have been held to illusions of what the photon is doing in this "gravitational field" while the events themself unfold?

In the overview of the universe in expression, it is good to see the "new updated versions" of what is entailed in the universe in that flash. I say it is never without the complete view of the standard model and it's extensions, that all it's expressions in such a flash unfolding, would have these things inclusive?

So Gravitons as well.

So how shall we see such "condensation of results" lead from such gathering of gravitons as we look at the events unfolding in this example?

Maybe some more research for myself here, as to what dark matter is?

The hot gas in each cluster was slowed by a drag force, similar to air resistance, during the collision. In contrast, the dark matter was not slowed by the impact because it does not interact directly with itself or the gas except through gravity. Therefore, during the collision the dark matter clumps from the two clusters moved ahead of the hot gas, producing the separation of the dark and normal matter seen in the image. If hot gas was the most massive component in the clusters, as proposed by alternative theories of gravity, such an effect would not be seen. Instead, this result shows that dark matter is required.


I haven't been following the results nor the conversation from the annoucement. But now that I have, what will come from reading it?

I'll take a look.



CXC: What's your interest in dark matter? Why is it important to understand the behavior of dark matter?

MM: The nature of dark matter is one of the most important topics in astronomy, so everybody is interested. Little is known about it -- all that the numerous searches for dark matter particles have done is ruling out various hypotheses, but they never got any "positive" results. So any new piece of evidence is valuable.
