New Kind of Dark Matter Could Form 'Dark Atoms'

New Kind of Dark Matter Could Form 'Dark Atoms' | The Atoms Life | Scoop.it

Most of the matter in the universe may be made out of particles that possess an unusual, donut-shaped electromagnetic field called an anapole. This proposal, which endows dark matter particles with a rare form of electromagnetism, has been strengthened by a detailed analysis performed by a pair of theoretical physicists at Vanderbilt University: Professor Robert Scherrer and post-doctoral fellow Chiu Man Ho. An article about the research was published online last month by the journal Physics Letters B.

 

“There are a great many different theories about the nature of dark matter. What I like about this theory is its simplicity, uniqueness and the fact that it can be tested,” said Scherrer.

 

e existence of dark matter via its gravitational effects on the movements of stars and galaxies. Most researchers think dark matter is composed of a new type of particle, one that interacts very weakly at best with all the known forces of the universe save gravity. As such, dark matter can almost never be seen or touched, and rarely even collides with itself. This might not hold true for all forms of dark matter, though. Now, some researchers suggest a new kind of dark matter could exist, representing about one-fifth of all dark matter in the universe, making it potentially as plentiful as conventional matter.

 

These new dark matter particles would essentially consist of heavy "dark protons" and light "dark electrons." They would interact with each other far more than other dark matter particles to form "dark atoms" that use "dark photons" to interact through a sort of "dark electromagnetism," much as regular protons and electrons interact through photons in conventional electromagnetism to build the atoms making up the stuff of everyday life. If dark atoms are possible, they could react with each other for dark chemistry, much as regular atoms interact chemically.

Camila Gomez Duclos's insight:

   Researchers say that the dark matter that makes up most of the universe could be part of the invisible and intangible counterparts.

   Dark matter is nonluminous material that is postulated to exist in space and that could take any of several forms including weakly interacting particles or high-energy randomly moving particles.

   Most scientists think that dark matter is made up of a new particle, one particle that interacts weakly with all the known forces in the universe.

   This theory might not hold true for every form of dark matter. Some researchers are saying that there is a new kind of matter that could exist, representing about one-fifth of all dark matter of the universe.

"But boss, they already can't see us," said tertiary atom C.

 

"Shaddup and put the face paint on," replied primary atom A. "More and more of those fancy-ass scientists aren't just seeing us, they're fucking with us, stickin' us in chambers and makin' us run into each other because they want to gawk at the wreckage."

 

And it was true, modern-day atoms were feeling positively hunted. They felt they needed a plan to slip back into the peaceful shadows...

Camila Gomez Duclos's insight:

   A team of astronomers have recently discovered evidence that the black hole high-speed jets are filled with power from heavy atoms.

   Astronomers have always known that black holes are filled with low mass particles. In a new discovery using the Compact Array Radio Telescope and the European Space Agency’s XMM-Newton Space Telescope astronomers found the first evidence of heavy atoms in black holes.

   CSIRO researcher Tasso Tziomis said, “Jets from supermassive black holes help determine a galaxy's fate — how it evolves.”

   Jets are beams of matter emitted at high speeds from a central object. In this case they are emitting form the black hole.

'Diamond Planets' Crappy For Life (As We Know It)
Discovery News
Of course, the key substance for life on Earth is water, a.k.a. H2O — two hydrogen atoms combined with one oxygen atom.
Camila Gomez Duclos's insight:

   Scientists have carbon-rich alien worlds that may turn into exotic planets with diamonds coming out of the surface, or layers of diamond gravel. However, models conclude that the so called “diamond planets” aren’t life’s best friend.

   “The building blocks that went into making our oceans are the icy asteroids and comets,” Torrence Johnson of NASA’s Jet Propulsion Lab said. “If we keep track of these building blocks, we find that planets around carbon-rich stars come up dry.”

   There is, however, a problem according to Johnson and his colleagues, the extra carbon found in the “diamond planets” would lock with oxygen. It would prevent the oxygen from bonding with hydrogen. The key substance to life is H2O. In this scenario, life would and could not exist.

The largest star ever discovered is tearing itself apart

The largest star ever discovered is tearing itself apart | The Atoms Life | Scoop.it
At 1,500-times wider than our sun, red supergiant W26 is the biggest known star in the Universe. But new observations reveal W26 is dying.
Camila Gomez Duclos's insight:

   Scientists have discovered that the biggest known star in the Universe is tearing its self apart. The red supergiant W26 is 1,500- times wider than our sun! Watching the star while it dies could help researchers figure out how dying supergiants could supply ingredients to make planetary formation and maybe even life.

   The W26 is among hundreds of thousands stars making a superstar cluster known as Westerlund 1. Westerlund 1 is the largest congregation of stars known in the Milky Way. It’s 16 light-years from Earth, in cosmic terms it’s just a stone’s throw away.

   While investigating Westerlund 1 Royal Astronomical Society researcher Nick Wright made an unexpected discovery…

A new microscope invented at Michigan State University allows scientists to zoom in on the movements of atoms and molecules.
Camila Gomez Duclos's insight:

   Michigan State University invented a new microscope that can zoom in on the movement of the molecules and atoms.

   The electron microscopes let scientists see the structure of the microorganisms, cells, metals, crystals, and other structures that aren’t visible using light microscopes. These images have helped scientists make many new discoveries, but the relationship of structure and function could only be estimated.

   MSU associate professor of physics and astronomy, Chong-Yu Ruan, has made these “molecular movies”.  You can watch the properties of the materials change.

   Ruan’s team is one of the few in the world actively making electron based images on the femtosecond timescale.

A Single-Atom Light Switch. The Quantum Light Switch: It can occupy both possible states at the same time. by Florian Aigner Vienna, Austria (SPX) Nov 09, 2013.
Camila Gomez Duclos's insight:

   At the Vienna University of Technology just a single atom can be used help switch light between two fibre optic cables. This kind of switch enables quantum phenomena, which can be used for information and technology.

   Scientists are trying to build optical switches at the smallest scale to manipulate light. This can now be accomplished by using a single atom. Conventional glass fibre can be connected by quantum systems.

   Vienna University of Technology’s Professor Arno Rauschenbeutel and his team caught light in “bottle resonators”. Light runs in circles at the surface of the bulgy glass objects.

   Arno Rauschenbeutel explained, “When the circumference of the resonator matches the wavelength of the light, we can make one hundred percent of the light from the glass fibre go into the bottle resonator - and from there it can move on into a second glass fibre."

Physicists have taken another step forward in exploiting light's vast unused potential as an information carrier.
Camila Gomez Duclos's insight:

   Germany researchers have calculated how “twisted” light beams can influence electrons inside hydrogen atoms; beam’s angular momentum. The theory has not been confirmed yet, but the team states that their work could lead to retrieving and storing quantum information.

   Spin angular momentum is a property of electromagnetic waves. But electromagnetic waves can also possess orbital angular momentum (OAM). OAM means a beam’s wavefront spirals around its propagation axis. This kind of beam has zero intensity at its center and has an undefined beam.

   OAM-carrying beams are known as twisted beams. This type of beam is used in research frequently.  OAM-carrying beams can be transmitted through glass fiber.

Bending World's Thinnest Glass Shows Atoms' Dance - Science Daily (press release)

Bending World's Thinnest Glass Shows Atoms' Dance - Science Daily (press release) | The Atoms Life | Scoop.it

Watch what happens when you bend and break the world's thinnest glass. This glass was recently featured in the Guinness Book of World

Camila Gomez Duclos's insight:

   Cornell researchers and their international team of collaborators were recently featured in the Guinness Book of World Records for bending and breaking the world’s thinnest glass. This glass is made of the same compound as windowpanes.

   A team of researchers led by David A. Muller started to use an electron microscope to bend, break, and melt one-molecule- thick glass. For the first time researchers were able to get images of the deformation which caused the atoms to “dance”.

   Glass is difficult to study even though it’s a common material. The atoms are rigid like a crystal but disordered like a liquid in glass because it’s an amorphous solid.
