Earthbound Antimatter Mystery Deepens After Scientists Rule Out Pulsar Source

The recent finding, detailed in the journal Science today (Nov. 17), concerns positrons, the antimatter complements of electrons. High-energy particles, usually protons, traveling across the galaxy can create pairs of positrons and electrons when they interact with dust and gas in space, study co-author Hao Zhou, at Los Alamos National Lab, told Space.com. In 2008, the space-based PAMELA detector measured unexpectedly high numbers of earthbound positrons. This was about 10 times what they were expecting to see, according to Zhou.

...

Zhou's team made detailed measurements of the gamma-rays coming from the direction of two nearby pulsars — Geminga and its companion PSR B0656+14 — that are the right age and distance from Earth to account for the excess positrons. To do this, the scientists used the High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory, located about 4 hours east of Mexico City. HAWC comprises more than 300 tanks of extra-pure water. When gamma-rays plow into the atmosphere, they create a cascade of high-energy particles. As this shower of particles passes through HAWC's tanks, it emits flashes of blue light, which scientists can use to determine the energy and origin of the original cosmic ray.

The data from HAWC revealed that particles are streaming away from the pulsars too slowly to account for the excess positrons, according to a statement by the University of Maryland, whose researchers also contributed to the work. In order to have arrived here by now, the particles would have needed to leave before the pulsars had formed...

Zhou's colleagues are quick to point out an important caveat. "Our measurement doesn't decide the question in favor of dark matter, but any new theory that attempts to explain the excess using pulsars will need to match the new data," University of Maryland physicist Jordan Goodman...said...

The gods are sick and tired of all the Democrap lies. The gods are bombarding us out of existence with anti- matter ( it’s not another flood so it’s ok).

The only defense is Anti-Anti Matter.

The layman calls this peanut butter.

Geminga and its companion PSR B0656+14

Not that there's anything wrong with that.

Is it positively negative?

Or is it negatively positive?

These crazy mixed up particles have me all charged up.

‘Dark matter’ is a newly dead theory.
Several recent studies have killed it.

“unexpectedly high numbers” Sorry, scientist, but your expectations don’t tell the Universe what to do. You need to revise your expectations.
Is this “dark matter” or antimatter? Is there any such thing as antimatter dark matter? would that be light matter? Or does any of this matter?

I thought antimatter didn't play well with regular matter - looks like they're trying out some new theories because it sounds good and insures continued funding.

I’ve always thought DM was a fudge factor. But where is the theory refuted?
