Do we feel forces of Dark Matter?

[peter]

Hi; Guys,

A picture of a ghostly ring (see the attached picture) attracted my curiosity, it was posted last year, claimed as the strongest evidence of the existence of dark matter, many of you saw this before.

This Hubble Space Telescope composite image shows a ghostly "ring" of dark matter in the galaxy cluster Cl 0024+17. The ring-like structure is evident in the blue map of the cluster's dark matter distribution. The map is superimposed on a Hubble image of the cluster. The ring is one of the strongest pieces of evidence to date for the existence of dark matter, an unknown substance that pervades the universe.

The ring looks like clouds and the galaxies are submerged in the such clouds. One can image that the motion of the galaxies in such dark matter should be similar to objects (airplanes, rockets, etc) moving through the clouds in our atmosphere. If our Milky Way is in such dark matter clouds (most likely yes), the dark matter should be around us everywhere, we should have some way to detect it.

I don't believe in ghosts.

 

It looks like ordinary dark matter to me, as opposed to non baryonic dark matter. It is a well-known fact that much of the mass in the universe is hardly visible to our telescopes, e.g. low mass stars that no longer burn hydrogen into helium: Other examples of dark matter include planets, comets, asteroids, rocks, dust, molecules, and atomic gas (and their constituent protons, neutrons and electrons), brown dwarfs, often called “massive astrophysical compact halo objects” (MACHOS). Theses are objects with very little surface luminosity.

 

The photo depicted above is clear evidence for the existence of baryonic dark matter. We know that dark matter exists in the form of faint objects—collectively referred to as brown dwarfs. These are low luminosity objects that are very difficult to detect because they are very weak emitters of electromagnetic radiation.

 

 

"It’s really exciting if it’s right"

said Massey.

 

 

 

It's even more exciting if it's wrong.

If it is the case, then we should observe a lot of more collisions than we observe today.

But it's even more exciting if it is wrong.

It is nice quote.;)
