Quasars are ‘cosmic signposts’ pointing to rare supermassive black hole pairs

Posted by in categories: cosmology, physics

The findings could aid the hunt for these monstrous duos using gravitational waves, tiny ripples in space and time (united as a 4-dimensional entity called space-time), which were first predicted in Einstein’s theory of general relativity in 1915.

“These findings are useful for targeted searches for supermassive black hole binaries, in which we search specific galaxies and quasars for continuous gravitational waves from individual supermassive black hole binaries,” research lead author Andrew Casey-Clyde, a doctoral candidate at the University of Connecticut and visiting researcher at Yale University, told Space.com.

“Our results mean that these targeted searches will be up to seven times more likely to find gravitational waves from a supermassive black hole binary in a quasar than in a random massive galaxy,” Casey-Clyde said.

One of the greatest mysteries of science could be one step closer to being solved

Posted by in categories: cosmology, particle physics, quantum physics, science

Around 80% of the universe’s matter is dark, meaning it is invisible. Despite being imperceptible, dark matter constantly streams through us at a rate of trillions of particles per second. We know it exists due to its gravitational effects, yet direct detection has remained elusive.

Researchers from Lancaster University, the University of Oxford, and Royal Holloway, University of London, are leveraging cutting-edge quantum technologies to build the most sensitive dark matter detectors to date. Their project, titled “A Quantum View of the Invisible Universe,” is featured at the Royal Society’s Summer Science Exhibition. Related research is also published in the Journal of Low Temperature Physics

The team includes Dr. Michael Thompson, Professor Edward Laird, Dr. Dmitry Zmeev, and Dr. Samuli Autti from Lancaster, Professor Jocelyn Monroe from Oxford, and Professor Andrew Casey from RHUL.

How to explain our inner awareness that is at once most common and most mysterious? Traditional explanations focus at the level of neuron and neuronal circuits in the brain. But little real progress has motivated some to look much deeper, into the laws of physics — information theory, quantum mechanics, even postulating new laws of physics.

Huge neutrino detector sees first hints of particles from exploding stars

Posted by in categories: cosmology, particle physics

Kamiokande-II saw the first supernova neutrinos from the famous SN 1987A.


Every few seconds, somewhere in the observable Universe, a massive star collapses and unleashes a supernova explosion. Japan’s Super-Kamiokande observatory might now be collecting a steady trickle of neutrinos from those cataclysms, physicists say — amounting to a few detections a year.

These tiny subatomic particles are central to understanding what goes on inside a supernova: because they zip out of the star’s collapsing core and across space, they can provide information about any potentially new physics that occur under extreme conditions.

Putting Black Holes Inside Stuff | Dead Planets Society Podcast

Posted by in categories: asteroid/comet impacts, cosmology, existential risks, physics

Primordial black holes are tiny versions of the big beasts you typically think of. They’re so small, they could easily fit inside stuff, like a planet, or a star… or a person. So, needless to say, this has piqued the curiosity of our Dead Planeteers.

Leah and Chelsea want to know, can you put primordial black holes inside things and what happens if you do?

Using Black Holes to Traverse the Universe with Dr. David Kipping

Posted by in category: cosmology

The Halo Drive, using a laser to gain fuel free relativistic propulsion from a black hole. By shooting a laser close to the event horizon of a black hole, Dr. David Kipping’s conceptual star drive could lead to traveling across the milky way from one black hole to another as well as techno signatures from advanced civilizations that might already be using this intergalactic relay system.

The halo drive: • the halo drive.

New Paper Claims Dark Matter May Be Made Up Of Tachyons Traveling Faster Than Light

Posted by in category: cosmology

A lot of additional research will need to be done on this subject, but it is always good to see new ideas being presented, especially when they challenge the accepted theories.

Very interesting theory, but…

I thought nothing could travel faster than light.
