Russia: U.S. exit from nuclear treaty would be a dangerous step - TASS

Russia: U.S. exit from nuclear treaty would be a dangerous step - TASS Washington's planned withdrawal from the international Intermediate-Range Nuclear Forces Treaty would be a very dangerous step, Russian Deputy Foreign Minister Sergei Ryabkov was quoted as saying by TASS news agency on Sunday. President Donald Trump said on Saturday the United States would exit the Cold-War era treaty that eliminated a class of nuclear weapons. He cited Russian violations of the agreement as the reason behind the withdrawal. Ryabkov said the step would draw criticism by the global community, TASS reported.

Dark matter hitting black holes could be the source of some fast radio bursts – mysterious blasts of radio waves that come from billions of light years The stuff we see in space – stars , planets and gas – only makes up about 18 percent of the mass of the universe. The rest is dubbed dark matter , which

The Russian scientists say Bose stars may be behind the mysterious ‘ fast radio bursts ’ being detected by radio astronomers. Currently, these have no known source.

The elusive material - which makes up 80 per cent of our universe but has never been observed - could be clumping together into 'cold stars', a study suggests.

These stars may be behind the mysterious 'fast radio bursts' detected by radio astronomers across the globe.

Bose Stars ( dark matter in origin). Fast radio bursts may be firing off every second. September 21, 2017. The search for mysterious " fast radio bursts " – very brief but intense pulses of radio waves from outer space – is heating up. Mysterious straight bright stripes have been discovered on Saturn's moon Dione, says research by Planetary Science Institute Associate Research Scientist Alex

Of mystery . The Russian scientists say Bose stars may be behind the mysterious ‘ fast radio bursts ’ being detected by radio astronomers.

Currently, these strange signals have no known source, and some had suggested they were messages sent by extraterrestrials.

The research comes from a team of scientists at the Institute for Nuclear Research of the Russian Academy of Sciences in Moscow.

Their computer models simulated how dark matter may interact around the edges of dwarf galaxies - the smallest galaxies in the known universe.

'In our work, we simulated the motion of a quantum gas of light, gravitationally interacting dark matter particles,' said study lead author Dmitry Levkov.

The simulations showed that dark matter may clump together into cold, unseen 'Bose stars' within a galaxy's halo - the ring of gas and dust around its outer edge.

Cold case disappearances in outback mining town could be linked

Cold case disappearances in outback mining town could be linked The cold case disappearances of a teenage girl and a woman from the outback mining town of Coober Pedy in the early 1990s could be linked, police have revealed. For decades, detectives have treated the suspected murders of Karen Williams, 16, and Anna Rosa Liva, 30, as unrelated cases but they're no longer so sure. "We cannot rule out that they're connected," Detective Sergeant Paul Ward said. "The location where Anna Rosa Liva disappeared from is certainly interesting.

The mystery of dark matter may have been solved. Dark matter was first conceptualised in 1977 which is thought to make up 85 per cent of the universe, is responsible for all of the unseen When the theory was first established, experts said that dark matter consisted of hypothetical Ringwald, of the DESY research centre in Germany, said : “ Dark matter is an invisible form of matter which until

Dark matter is a hypothetical substance said to make up roughly 27 per cent of the universe.

The enigmatic material is invisible because it does not reflect light, and has never been directly observed by scientists.

It is thought the material can clump together into something called a Bose-Einstein condensate.

Pictured left is a simulation of the initial moment of this process, when the gas is mixed. Right shows the moment shortly after the formation of a Bose star.

When temperatures sit just above absolute zero, quantum particles lose the energy to mix and wobble, leaving behind a uniform dark 'slush'.

Individual quantum particles become uniform and clouds of them are drawn together by gravity to form superfluids.

This image has exactly 12 dots, but it’s impossible to see them all at once Our entire visual field is not made the same. You can never see it all at once. Twelve black dots dance about this grid. T hey never actually move or vanish, but no matter how fast you twitch your eyes back and forth, you can’t seem to trap them all in your gaze at once. Ninio’s extinction illusion is a riff on the Hermann grid, a classic piece of visual trickery in which your eyes see illusory gray blobs at the intersections of a black-and-white lattice. We don’t know exactly why the Hermann grid happens, says Susana ­Martinez-​Conde, a neuroscientist at the State University of New York’s Downstate Medical Center.

radio bursts might be — in blunt terms — stars made of dark matter slamming into black holes. believes, subscribes to the theory that dark matter — the mysterious stuff that makes up about 85 which may be what scientists on Earth have observed as FRBs — low energy radio wavelengths.

Even though the very nature of dark matter is still a mystery to science, let alone evidence of invisible “ stars ,” a new mathematical model, proposed by a team of Russian researchers, suggests that dark The mysterious matter , making up around 80 percent of the mass in the universe, is still impossible

The new study suggests Bose-Einstein condensate forms in the halos of dark galaxies, and they could form in a timespan shorter than the lifetime of the universe.

If they exist, Bose stars may be responsible for mysterious signals known as Fast Radio Bursts that have baffled scientists for decades.

According to the scientists, dark mark can interact with electromagnetic fields and decay into radiophotons.

These then travel billions of miles where they are picked up by sensitive equipment on Earth.

'This effect is vanishingly small, but inside the Bose star, it may be resonantly amplified, as in a laser, and could lead to giant radio bursts,' they said.

For now, the team is looking for a way to detect and quantify these invisible stars.

'The next obvious step is to predict the number of the Bose stars in the Universe and calculate their mass in models with light dark matter,' Dr Levkov said.
