Dark Matter Observed

Dark Matter observed by KIPAC/SLAC (CA) in a galaxy cluster 3 billion light years from earth using gravitational lensing to detect DM mass (DM doesn't reflect light or give off heat but GL detects the distortion in light of background galaxies caused by DM), artificial colour applied to distinguish between dark matter (blue) and luminous matter (red). The bullet cluster consists of 2 clusters of galaxies passing through one another. As the two clusters cross at a speed of 10 million miles per hour, the luminous matter in each cluster interacts with the luminous matter in the other cluster and slows down. But the dark matter in each cluster does not interact at all, passing right through without disruption. This difference in interaction causes the dark matter to sail ahead of the luminous matter, separating each cluster into two components: dark matter in the lead and luminous matter lagging behind. Observations were made using the Hubble Space Telescope, the Magellan Telescopes and the Very Large Telescope source/more info- http://home.slac.stanford.edu/pressreleases/2006/20060821.htm

I Really Like The Video From Your in a galaxy cluster 3 billion light years from earth using gravitational lensing to detect DM mass

Your Video Is Very Useful Sharing in a galaxy cluster 3 billion light years from earth using gravitational lensing to detect DM mass

@thinkrealify The artist's rendition/animation obviously showed the galaxys passing far through each other, when if you look at the original image captured, you see that we miraculously observed it right as it separated. The animation shows what would have occurred in the past and future.

Isn't dark (missing) matter if you can see it now is it. The reason some people think galactic matter is missing is that the rotational speeds of galaxies aren't the expected speeds. They want to know what matter is creating the extra gravitational force that slows objects in galactic rotation the further out they are from center. Ditch Newtonian for this. Think general relativity and gravity stretching. Use MOND formulas. The Gravity is there but the mass is time shifted.

@thinkrealify That is true, but I think they interpolate a lot of the data, still it would more guesstimation than observation.

@dementor338 lol

[thinkrealify]

So fake. At 10million miles per hour it would take thousands if not millions of years for 2 galaxies to go through each other. Telescopes haven't been around that long.

Weird

wheres the sound?

This is clearly a computer simulation. Your title is misleading.
