Andrei Derevianko, of the University of Nevada, said: "Despite solid observational evidence for the existence of dark matter, its nature remains a mystery. Some research programs in particle physics assume that dark matter is composed of heavy-particle-like matter. This assumption may not hold true, and significant interest exists for alternatives.

A signal picked up by Dutch and Swiss scientists is thought to be the first phsical evidence of Dark Matter


It was first theorised more than 70 years ago, but after decades of searching, scientists believe they have seen the first sign of elusive Dark Matter.

Researchers have picked up unexpected signals coming from a cluster of galaxies in the constellation Perseus and in the Andromeda galaxy.

All atoms emit a distinct pattern of light called a spectrum which is how astrophysicists can determine what planets and stars are made from at great distances.

In a recent ESA meeting in Ferrara the scientists managing the Planck satellite observatory said that the excess of high energy positrons in space is not due to the annihilation of dark matter, as it was proposed. When I find a link I shall post it.

Strange matter???

Forget dark matter, STRANGE matter could be lurking somewhere in the universe - and there may be entire stars made of it

Scientists at the National Institute for Space Research in Brazil say an undiscovered type of matter could be found in neutron stars
Here matter is so dense that it could be 'squashed' into strange matter
This would create an entire 'strange star' - unlike anything we have seen
However, the exact properties of strange matter are unknown
If it exists, though, it could help scientists discover ripples in space-time known as gravitational waves

New revelations show how much we still don't know about our universe and how much is still just guesswork.

Scientists at the National Institute for Space Research in Brazil say an undiscovered type of matter could be found in neutron stars. Here matter is so dense that it could be 'squashed' into strange matter. This would create an entire 'strange star' - unlike anything we have seen. The theory was proposed by Dr Pedro Moraes and Dr Oswaldo Miranda, both of the National Institute for Space Research in Brazil.

What the properties of this matter would be, though, are unknown - but it would likely be a ‘liquid’ of several types of sub-atomic particles. If it exists, though, it could help scientists discover ripples in space-time known as gravitational waves

The Mail is well known for these tyoe of sci headlines, but I'm not holding my breath here.

We'll have to abide and see how many discoveries will still be made before we can have a clear view on how the Universe is compiled.

Don't know how we got into Lead. I do know that early canning used lead as a sealer; this was about at the time of the American Civil War. Canned foods allowed an Army much more mobility. It also lead to many deaths and illnesses from this lead in early canned goods.

I'll continue the off topic discussion. Wasn't Shackleton's arctic expedition ruined by lead poisoning from the canned food they brought with them?

Now where did that dark matter and energy go?

Back on Topic:
I continue to say": If there is Dark Matter then let's send a probe and bring some of it back for analysis.

I thought it was supposed to be all around us. Or was that dark energy. I still say that if over 75% of the universe is made up of dark matter and dark energy then we don't know nuthin about nuthin regarding the universe and it's fate.

Dark Matter only interacts with matter via gravity, and weakly at that. According to Brian Greene, it could also be the weak gravitational pull of another universe through the higher dimensions of this universe, if M-theory is correct. It cannot be collected and studied like ordinary matter, in either case. Its effects only become noticeable at interstellar distances and larger.

Dark Energy is the miniscule expansion of the universe. Its effects only become noticeable at intergalactic distances and larger due to the vastness of space and how relatively small the expansion is on our scale.

Sure... Analyzing Dark Matter..., Good Luck!

On the December issue of Cern Courier there is a book reviewed on this subject. The book is "Behind the Scenes of the Universe From the Higgs to Dark Matter" by Gianfranco Bertone, Oxford University Press.

It's out there and they can't find it.

Hypothetical particle may get to the heart of universe's dark matter



A completely new type of fundamental particle may explain the mystery of “dark matter”, the missing material that makes up more than 80 per cent of the universe’s mass, British scientists believe.

Dark matter reveals itself in the way its gravity affects stars and galaxies, but has never been directly observed.

University of Southampton researchers believe one reason may be that dark matter particles are much lighter than has previously been proposed, with the mass of only 0.02 per cent of an electron. Their findings are published in the journal Scientific Reports.

Makes me think that we need to have another look at Neutrinos.

Yes, "sterile neutrinos".

And if the Universe isn't FLAT, which is proven it isn't...than the omega energy in the Universe isn't ewqual to 0...and Universe became in a Sea of some MATHER, which does not interfece with the laws within this Universe...than, we can only speculate about the Dark mather!
