Do you remember what I wrote about Dark matter could be heating the core of the Earth causing global warming.

sometime you need to listen, now ask yourself how we knew that. things you are not told.

Since for the most part, it doesn't interact with matter except gravitationally, do you have any proposed mechanism for it to heat the core of the Earth?

And, it appears that only you are making this suggestion - no where in that article is any such thing mentioned.

It is the gravitational field that is reacting with the dark matter particals that is reacting with the cores of all the planets including moons and the sun, yes this happens throughout all galaxy's. it would not be the first time a book on the cosmos has had to have been rewritten. the gravitational field loops back to the core of the said planet or sun. time will tell.

[DrPizza]

The gravitational field isn't a loop. You must be thinking of magnetic fields.

holy crap... I believe this is the first thread in highly technical I feel much stupider for having read...

Someone got brain bleach? Maybe I can wash it out...

[shaynoa]

Yes sorry did mean magnetic field not gravitational, sorry if you can't keep up {jaqie}

[jaqie]

You can't keep up...really.

I'm feeling a little underwhelmed.

Some of the International Space Station’s most anticipated science results are in, but their interpretation — which hints at a dark-matter detection — is likely to be debated by physicists for years to come.

Principle investigator Samuel Ting presented the first data today from the Alpha Magnetic Spectrometer (AMS), a US$1.5-billion cosmic-ray detector fixed to the outside of the station. In a talk at CERN, the particle-physics facility near Geneva, Switzerland, Ting told physicists that the mission has confirmed data from the European satellite Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics (PAMELA) and NASA’s Fermi Gamma-ray Space Telescope showing that something in the Galaxy is spewing out many more positrons — the antimatter counterparts of electrons — than can be accounted for from known astrophysical sources.

Yet the spectrum of this antimatter excess is far from a smoking gun for models in which the extra positrons are generated through the annihilation of dark-matter particles colliding with each other. “The detailed interpretation of our data probably will have many theories,” says Ting.

Comprising a giant magnet and eight particle trackers, the AMS was launched in 2011 after a 17-year campaign by Ting, a physicist and Nobel laureate at the Massachusetts Institute of Technology (MIT) in Cambridge, to place an antimatter detector in space. Now, in a paper to be published in Physical Review Letters, Ting and his team say that over the mission's first 18 months of operations, they observed some 6.8 million positrons and electrons, at energies up to 350 gigaelectronvolts (GeV). These are higher-energy events than PAMELA and Fermi were able to see, but still less than half the energy that AMS will be sensitive to over its 15-year lifetime. The detection accuracy of the AMS falls with increasing energy, and Ting and his team have chosen not to release data at energies above 350 GeV because the results do not yet have enough statistical significance to give a definitive picture.

Still, the spectrum looks promising. It shows a rise of positrons with energy that begins to flatten off at energies above 250 GeV. If the signal is caused by dark matter, the number of positrons should rise and then drop again around the mass of the dark-matter particle, which cannot produce positrons more energetic than itself. The data provide “a tantalizing hint of something exciting”, says Michael Turner, a theoretical cosmologist at the University of Chicago in Illinois.

An alternative theory is that the antimatter could be emanating from pulsars, rotating superdense stars in the Galaxy whose properties are not perfectly understood. “I personally think the pulsar explanation is more viable now,” says Dan Hooper, a theorist at Fermilab in Batavia, Illinois. He is struck by the absence, so far, of a sharp decrease in antimatter at higher energies.

But Ting says that the AMS collects antimatter uniformly from all over the sky, which does not seem to indicate that specific astrophysical point sources, such as pulsars, are the cause.

One problem, raised by Peter Fisher, an AMS collaborator at MIT, is that there is still no consensus about what the expected background rate of antimatter in the Galaxy should be — and, therefore, about how much of an excess the AMS is seeing. “It’s like playing blind-man’s bluff,” he says. Despite the anticipation that has built around this announcement, he and Ting now say that physicists will have to wait another couple of years for the AMS to release its higher-energy data to know whether the excess is due to dark matter, pulsars or something else.

cool. this just in! we hardly know what were doing

Thanks, Gibsons, for saving the thread with some intelligent information!

They just don't have enough of a sample yet.

~300 GeV will be easily detectable for LHC when it comes back online after the upgrade.

Sorry, I was just having a bit of fun. I'll refrain from such in this forum going forward (if I ever even post here again).

So you're Shaynoa? Aren't alternate accounts prohibited?

I have no idea who or what you are talking about.

Then you haven't read the thread. I'm pretty sure jaqie wasn't talking about you.

[jaqie]

irishScott, correct.

I was hoping for a 'breakthrough.' Maybe I shouldn't pay so much attention to newsy headlines.

Could you imagine what the religous world would do if they found out that there was human life on Mars or even a life form equall or greater than human.
That would blow there level of understanding and there beliefs right out the window simply because they have lived in a box all there life and never looked outside of that box.
Very soon things are going to be made known about the creator or what ever any one wishes to call him, and it is that simple it has be over looked, a child could understand it, and it's all because we are so small on the scale of things.
Most religous people are to busy listening to the man that stands up the front in there so called church, right within the word church is a total misunderstanding within it's self.
So what is a church, many people have been lead to believe that a church is a building, [ WRONG ] a church is a gathering of people 2 or more in a park, pretty much where ever but for a building, and always remember the creator states he does not dwell in a house or temple built by the hands of man, and also remember the scriptures state you shale only worship to the throne of the creator and to him to whom sits apon it, [ IT DOES NOT STATE AT ALL TO WORSHIP THE VIRGIN Mary, it only states that she will be remembered nothing more.
So here are a few simple facts on why you have not been told that much at all

Hello, how are you? Thank you for sharing your thoughts.

What is the Sorry on Dark matter?

I think if it consists of nothing it would be like explaining that life doesn't really exist and we are imagining being alive.?????

Lets face it there doesn't need to be life on mars to prove there is life else where in this universe, its completely rational to realize we aren't the only special living entities in this or the next cosmoses.

So life on mars to me is like saying a man landed on the moon... its done and its only when we find something that all hell wil probably break loose.

I would predict the first scientifically proven evidence of aliens will create bomb scares in already paranoid house holds.
