Reinterpreting dark matter: Could dark matter be regarded as a very cold quantum fluid?

Date:
July 2, 2014
Source:

University of the Basque Country

Summary:
Astronomers have explored cold dark matter in depth and proposes new answers about the formation of galaxies and the structure of the Universe. These predictions are being contrasted with fresh data provided by the Hubble space telescope. It is estimated that only a minute fraction of the matter in the Universe is baryonic matter, which forms stars, planets and living organisms. The rest, comprising over 80%, is dark matter and energy.

Well... Dark matters because without it light bulb sales would plummet! :eek:

But then you could put your stock into candles if it didn't matter.  :winkle:

Without dark candle sales would also plummet. You need to start a Change.org™ petition to save the dark.

Dark matter, a name given by scientists to give voice to a thing that is beyond their comprehension. In the end, what they chose to call it, is irrelevant, it simply, is.

As the Ikerbasque researcher explained, "guided by the initial simulations of the formation of galaxies in this context, we have reinterpreted cold dark matter as a Bose-Einstein condensate." So, "the ultra-light bosons forming the condensate share the same quantum wave function, so disturbance patterns are formed on astronomic scales in the form of large-scale waves."
Sounds interesting, I'd have to read up on this.  IIRC, they previous postulated that it was made up of weakly interacting massive particles (WIMPs).

At this point, Dark Matter is probably not just one thing.

It's little particles of GAWD and can see you nekid even in the dark!  Now stop touching yourself down 'there' right this moment!

Dark matter is invisible
can't be seen thats no bull
In outer space so its pretty cold
from the big bang so its really old

You wonder where that space all went
Dark matter! Like 80%!
So everything else is really scattered
stuck on this big wall of dark matter

I'd be surprised, wouldn't you?
if it turned out to be super glue.
But don't think too much, you'll be mad hatter
tryin' to figure out that shit, dark matter!  :biggrin:

The dark matter might simply be the lightest superpartner (sparticle): because it's lightness means it cannot decay into anything else. Apparently there would be a lot of them.

So basically dark matter is the same as asking if a bear shits in the woods and there's nobody there to see it does that tree next to the bear make a sound?

More like, does the bear have gravity?

Dark Matter is "dark" because it doesn't interact with the electromagnetic force - no photons, no light.

It's hypothesized because every galaxy is missing the needed mass to justify the rotation of the stars contained within it.

The real mystery is: how does every galaxy, of different sizes and masses, gets its needed Dark Matter when it forms? Where does it get from? (Hint: Goddidit)

We need another Laplace to resolve this issue and take God out of the equation.(Hint: Of course, I'm referring to what Laplace told Napoleon in regard to what Newton believe in order to keep the solar system stable).

I guess the dark matter clumps first, and then attracts the light matter. It's not really a chicken and egg thing. Or maybe it is: the egg came long before the chicken, as the DM came well before the LM.
