A new thought experiment shows how we could get information from a black hole

Posted by in categories: cosmology, physics, singularity

Physicists think they’ve come up with a way to learn a bit about the interior of a black hole — an impossible procedure that shows the insanity of studying the heart of a singularity.

Confronting the Multiverse: What ‘Infinite Universes’ Would Mean

Posted by in category: cosmology

Is it possible that our universe is but one of many, with laws that mean nothing in the “pocket universes” that co-exist all around, and through, us? Robert Lawrence Kuhn explores the multiverse with the help of the world’s leading experts on these theori.

Warp drive and wormholes could be used for time travel, says physicist

Posted by in categories: cosmology, space travel, time travel

Older, but interesting idea—


Warp drive and stargate wormholes could be used for time travel to the past. That’s the surprising conclusion that controversial theoretical physicist and author Dr. Jack Sarfatti has reached from his research into dark energy and dark matter.

We Finally Know What’s Inside These Mysterious Black Hole Clouds

Posted by in category: cosmology

Awe inspiring stuff, this.


Black holes are some of the strangest objects in the universe. But, just as impenetrable a mystery? The heavy cloud cover encircling some black holes. Now, for the first time, researchers say they’ve managed to get a glimpse inside of one of those clouds. And what they found has some serious implications for our most basic understanding of black holes.

Some black holes are shielded by heavy clouds of gas and dust that are so thick that they’re impossible to see through with our telescopes. The reasons why have plagued scientists. But a brand new X-ray view taken by a joint team from NASA and the European Space Agency of galaxy NGC 1068, and the black hole that lies at its center, just changed all that.

China’s dark-matter satellite launches era of space science

Posted by in categories: cosmology, particle physics, science

“The detector could help to clear up some mysteries. In 2013, the AMS announced it had seen hints of dark matter but so far it has detected too few high-energy particles to say for sure. Though DAMPE lacks the equipment to resolve the conundrum directly, it could reveal if the signal is caused by a different astrophysical source, such as pulsars, says Capell.

Although it will collect fewer incoming photons, DAMPE is better at pinpointing their energy than are existing γ-ray telescopes, such as NASA’s Fermi-LAT, says Miguel Sanchez-Conde, a physicist at the Oskar Klein Centre for Cosmoparticle Physics in Stockholm. This capability should allow DAMPE to see sharp spikes in radiation predicted by some dark-matter models.”

World’s most sensitive dark matter detector gets better

Posted by in categories: cosmology, particle physics

LEAD, S.D. [Brown University] — The Large Underground Xenon (LUX) dark matter experiment, which operates nearly a mile underground at the Sanford Underground Research Facility (Sanford Lab) in the Black Hills of South Dakota, has already proven itself to be the most sensitive dark matter detector in the world. Now, a new set of calibration techniques employed by LUX scientists has again dramatically improved its sensitivity.

Researchers with LUX are looking for WIMPs, weakly interacting massive particles, which are among the leading candidates for dark matter. “It is vital that we continue to push the capabilities of our detector in the search for the elusive dark matter particles,” said Rick Gaitskell, professor of physics at Brown University and co-spokesperson for the LUX experiment. “We have improved the sensitivity of LUX by more than a factor of 20 for low-mass dark matter particles, significantly enhancing our ability to look for WIMPs.”

The new research is described in a paper submitted to Physical Review Letters and posted to ArXiv. The work re-examines data collected during LUX’s first three-month run in 2013, and helps to rule out the possibility of dark matter detections at low-mass ranges where other experiments had previously reported potential detections.

A multiverse hiding in the Large Hadron Collider

Posted by in categories: cosmology, particle physics

Physicists will be looking for mini black holes when the Large Hadron Collider restarts this month. It’s impossible for the LHC to generate any sort of black hole that would be remotely unsafe, but this theory suggests that microscopic black holes that vanish almost instantly could be produced from the high-power particle collisions in the LHC.

In a Sudbury mine, physicists probe secrets of dark matter

Posted by in categories: cosmology, physics

Buried two kilometres underground in an active ore mine, DEAP-3600 is the most sensitive dark matter detector of its kind. Scientists are hoping to shine a light (so to speak) on one of the deepest mysteries of physics.

Tiny dark matter stars would harbour particles that act as one

Posted by in categories: cosmology, particle physics

A certain dark matter candidate could clump into stars where it would behave like the Borg race in Star Trek – and this might make it observable.
