Astroboffins map GIANT MASS of dark matter Astrophysicists have mapped the first 3D image of a gigantic dark matter filament for the first time. Hubble image with dark matter mass overlay Dark matter can't really be "seen" as such, it can only be detected by looking at the gravitational effects it has on the space around it. But by collating images from the Hubble …

"Why doesn't dark matter clump ?"
Dark matter has a sort of repulsive trade, at least towards regular matter, but it seems to dark matter itself too.
It doesn't clump: it wants to distribute itself as evenly as possible in the available space and would have done so if it wasn't affected by gravity.
A sort of an energy field for which we have no means of detection rather that the gravity with which it interacts.
Very strange stuff indeed...

@HolyFreakinGhost "The point of dark matter is that is *does* clump."
I'm not mathematically involved, but I beg to differ... :) If it really did clump, it would concentrate right in the core of stars, galaxy's etc. or in itself for that matter. It does not. It just floats in the vicinity of great lumps of matter (halo's of galaxies/clusters), "trying to get away" but grabbed by gravity. Gravity seems to win upto a point where the repulsion gets the upper hand, so it ends up in an awkward equilibrium.
This is for me the only way I can explain it for myself as far as I understand it, but, IANAM(athgeek)...

TYVM for the food for thought.
I only just recently started taking more interest in the DM/DE physics and don't know all these facts yet, so your story helps. An amateur with a keen mind, no more. It needs a bit of time to sink all in though.. :) I am thinking about an astronomy study after my retirement: a.t.m., I'm just an IT guy and need another 15 years or so before I really get the time to do that.

> What imparts mass to the Higgs boson ?
That question doesn't actually make massive sense. The Higgs has energy, hence mass. The fact that it "imparts mass" to other particles is something else entirely (it is also wrongly formulated as the Higgs boson is just a side-effect of the mass-imparting mechanism in the first place).
The gist of the matter: Learn Group Theory and Quantum Field Theory first, then start discussing. Not that I know anything about second quantization and whatnot.
That's not what they're saying, they're saying that theories that explain the universe by having it start with a Big Bang, Big Bang theories as opposed to say Steady State theories or religion, predict that dark matter will exist.
If they find dark matter where the theory says it should be then their theory isn't proved wrong.
Contrary to what science still believes, at the time of the Big Bang there were no atoms but only waves carrying energy through the infinite Void.
If we could view the Universe from outside, It would look like an egg-shaped cloud with winds running in perpetual motion inside of It.
The energy is like those winds running at maximum speed and pushing out the borders of the Universe.
The Universe continues to expand as the waves that travel at the border of the Universe have never encountered, nor will ever encounter, any interference from the Void. These waves will forever expand the Space of the Universe they create and leave behind.
Wave-behavior relates to the medium in which the waves travel.
Thus, wave-behavior at the border of the Universe is different than wave-behavior within the Universe.
Inside the Universe, waves change their frequencies by colliding with other energy during their travel. These waves, because of the encountered interference, continue to transform part of their original energy in other forms. Waves travel gradually releasing heat, or amounts of energy, and their original short wavelengths, in time become longer and longer as they carry less and less energy than they did when they first started to travel. These waves lose energy releasing it in form of other waves with wavelengths longer than their own.
For example, the gamma rays, over time, diminish their energy level (and their frequency) to become X rays, from X rays they will become ultraviolet and so on. The original quantum is not lost but distributed into other forms of energy through "spontaneous symmetry breaking".
Once reached an almost flat longitude (and lower critical energy level) these waves solidify into hydrogen atoms breaking up their energy in opposite elements, like the split ends of a broken hair.
When the hydrogen atoms are reached by the heat of other incoming waves they fuse together to create more complex forms of energy.

I’m looking at a pretty, blonde girl in the office right now. From my current perspective she appears to be 2 dimensional, however if I accidentally happen to change my perspective over to the kettle in a minute, or she does something similar, I’m sure I’ll find there are aspects of her I haven’t seen up to now..
