Extremely Dense Atom-sized Primordial Black Holes Could Weigh Millions of Tons, Experts RAtom-sized Primordial Black Holes Are Extremely Dense Objects That Could Weigh Millions of Tons, Experts Reveal

Posted by in categories: cosmology, particle physics

One of Albert Einstein’s theory of general relativity’s most fascinating predictions is the possibility of black holes, which are created after a massive star reaches the end of its life and collapses. Supermassive black holes as big as 100,000 or ten billion times the Sun are commonly found at the center of most galaxies.

Those are the biggest form of black holes, but it is also thought that primordial black holes (PBHs) also exist. Unlike the big ones, these tiny black holes emerged in the early cosmos through the gravitational collapse of extraordinarily dense areas.

Can You Trust Your Quantum Simulator? MIT Physicists Report a New Quantum Phenomenon

Posted by in categories: computing, particle physics, quantum physics

Physics gets strange at the atomic scale. Scientists are utilizing quantum analog simulators – laboratory experiments that involve cooling numerous atoms to low temperatures and examining them using precisely calibrated lasers and magnets – to uncover, harness, and control these unusual quantum effects.

Scientists hope that any new understanding gained from quantum simulators will provide blueprints for designing new exotic materials, smarter and more efficient electronics, and practical quantum computers. But in order to reap the insights from quantum simulators, scientists first have to trust them.

That is, they have to be sure that their quantum device has “high fidelity” and accurately reflects quantum behavior. For instance, if a system of atoms is easily influenced by external noise, researchers could assume a quantum effect where there is none. But there has been no reliable way to characterize the fidelity of quantum analog simulators, until now.

Tiny black holes can compress Mount Everest into an atom size

Posted by in categories: cosmology, particle physics

These tiny black holes lose mass faster than their massive counterparts, emitting Hawking radiation until they finally evaporate.

One of the most intriguing predictions of Einstein’s general theory of relativity.

When a sufficiently massive star runs out of fuel, it explodes, and the remaining core collapses, leading to the formation of a stellar black hole (ranging from 3 to 100 solar masses).

A Blast Chiller for the Quantum World

Posted by in categories: particle physics, quantum physics

Through optomechanical experiments, scientists aim to delve into the boundaries of the quantum realm and lay the groundwork for the creation of highly sensitive quantum sensors. In these experiments, everyday visible objects are coupled to superconducting circuits through electromagnetic fields.

To produce functional superconductors, these experiments are conducted inside cryostats at a temperature of around 100 millikelvins. However, this is still far from low enough to truly enter the quantum world. In order to observe quantum effects on large-scale objects, they must be cooled to nearly absolute zero.

Absolute zero is the theoretical lowest temperature on the thermodynamic temperature scale. At this temperature, all atoms of an object are at rest and the object does not emit or absorb energy. The internationally agreed-upon value for this temperature is −273.15 °C (−459.67 °F; 0.00 K).

The only things that travel at the speed of light are photons. Nothing with any mass at all can travel at the speed of light because as it gets closer and closer to the speed of light, its mass increases. And if it were actually traveling at the speed of light, it would have an infinite mass. Light does not experience space or time. It’s not just a speed going through something. All of the universe shifts around this constant, the speed of light. Time and space itself stop when you go that speed.

How to make a black hole.

There’s more than one way to make a black hole, says NASA’s Michelle Thaller. They’re not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.

Scientists Successfully Sent A Particle Back in Time Using A Quantum Computer

Posted by in categories: computing, information science, particle physics, quantum physics, time travel

As fantastic as this may seem this is not an impossible occurrence.


Before Einstein, time travel was just a story, but his calculations led us into the quantum world and gave us a more complicated picture of time. Kurt Godel found that Einstein’s equations made it possible to go back in time. What’s up? None of the ideas about how to go back in time were ever physically possible.

Before sending a particle back in time, scientists from ETH Zurich, Argonne National Laboratory, and Moscow Institute of Physics and Technology asked, Why stick to physical grounds?
