Dark matter pervades the entire universe and makes up for the bulk of its mass,

If so lets send a probe and bring some of it back.

Wouldn't that be something...

Researchers Make Progress in the Hunt for Dark Matter Through Space Station Particle Detector


New research published Thursday in the journal Physical Review Letters shows researchers are making important progress in the hunt for dark matter, using the Alpha Magnetic Spectrometer (AMS) -- a state-of-the-art cosmic ray particle physics detector located on the exterior of the International Space Station. The results include new detections of anti-matter particles that could provide new clues in the search for dark matter — invisible matter that can't be directly detected but can be inferred. An overview of the latest findings can be found here.

Here is another proposed instrument in search for Dark Matter:
Axions

Anti-matter has been known to be a small part of cosmic rays for some time now. This much is not new news.

Yes, but it seems there is an excess of positrons in a given energy range.

My niece is studying dark matter at Indiana U.

My niece is studying dark matter at Indiana U.

Where did they get it ??

How much do they have.

I think that it may be plankton !!!

Didn't know that field of study existed!

It's called astrophysics.

Astrophysics is correct.

Dark matter & energy

Dark Energy, Dark Matter

In the early 1990's, one thing was fairly certain about the expansion of the Universe. It might have enough energy density to stop its expansion and recollapse, it might have so little energy density that it would never stop expanding, but gravity was certain to slow the expansion as time went on. Granted, the slowing had not been observed, but, theoretically, the Universe had to slow. The Universe is full of matter and the attractive force of gravity pulls all matter together. Then came 1998 and the Hubble Space Telescope (HST) observations of very distant supernovae that showed that, a long time ago, the Universe was actually expanding more slowly than it is today. So the expansion of the Universe has not been slowing due to gravity, as everyone thought, it has been accelerating. No one expected this, no one knew how to explain it. But something was causing it.

Eventually theorists came up with three sorts of explanations. Maybe it was a result of a long-discarded version of Einstein's theory of gravity, one that contained what was called a "cosmological constant." Maybe there was some strange kind of energy-fluid that filled space. Maybe there is something wrong with Einstein's theory of gravity and a new theory could include some kind of field that creates this cosmic acceleration. Theorists still don't know what the correct explanation is, but they have given the solution a name. It is called dark energy.

Keep guessing folks, we still don't know, and maybe never will.

As long as more than 75% of what the universe is made up of remains unidentified claims that the fate of the universe is predictable are ludicrous at best. And calling it dark matter and dark energy is not the same as identification.

My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events.

Were dark matter and dark energy here before the big bang? I wonder if anyone is investigating that possibility.

I hope someone is. (Hi Bob :)) I wonder who we can ask?

I asked the internet something the other day and it was wrong... :/

I don't think that can be investigated... Found an interesting read tho:

There's a basic and advanced explanation on the page.

WOW!

Not so dark after all! Dark matter particles may FINALLY have been found - and they are coming from the core of the SUN

There have been plenty of 'false dawns' when it comes to dark matter, with a 'discovery' seemingly announced every few months.

But this latest announcement has understandably gripped scientists with excitement - because it might just be our first ever direct detection of the elusive particles.

Researchers have spotted a type of particle believed to make up dark matter coming from the sun towards Earth - and it may indicate that dark matter is produced in the cores of stars like our own.

What was found was an X-ray signal which may come from axions entering a magnetic field. I know there is a IAXO project at CERN aiming to use a superconducting magnet to detect such a signal while looking for axions.But this result needs independent confirmation, unless we want to repeat the gravitational wave fiasco of BICEP2 and the fake superluminal neutrinos.

Scientists to use GPS constellation to find secret ‘dark matter’

It is the matter that makes up most of our universe, but is invisible to the eye — and now, scientists may have a new way to study it.

“Dark matter” is hypothesized to be cosmic “kinks” or “cracks” in the topography of space, but it doesn’t emit or absorb light, so the only way to observe its effects is to witness how it alters gravity. Scientists now intend to use Global Positioning Satellites (GPS) to detect and measure dark matter, along with networks of ground-based atomic clocks, according to IBTimes.

The matter we can see and touch explains only 5 percent of the mass and energy in the world, with dark matter and energy making up the remaining 95 percent. However, the 50,000-kilometer-network of GPS satellites could help scientists spot these rifts in space and better measure them.
