Even though the strange behaviour we observe in the quantum realm isn’t part of our daily lives, simulations suggest it is likely our reality could be one of the many worlds in a quantum multiverse.

In a paper published in Physical Review Letters this week, physicists from Amsterdam and Copenhagen argue that close observations of merging black hole pairs may unveil information about potential new particles. The research combines several new discoveries made by UvA scientists over the past six years.
Some recent dark matter experiments have begun employing levitated optomechanical systems. Kilian et al. explored how levitated large-mass sensors and dark matter research intersect.
Levitated sensors are quantum technology platforms that use magnetic fields, electric fields, or light to levitate and manipulate particles, which become very sensitive to weak forces. These sensors are especially well suited for detecting candidates in regimes where current large-scale experiments suffer limitations, such as ultralight and certain hidden-sector candidates.
The authors discussed how these advantages make levitated sensors, including optically trapped silica nanoparticles, magnetically trapped ferromagnets, and levitated superconducting particles, ideal for detecting different dark matter candidates.

Astronomers have identified the largest and most distant water reservoir ever detected in the universe. This immense collection of water, equivalent to 140 trillion times the water in Earth’s oceans, surrounds a quasar over 12 billion light-years away.
“The environment around this quasar is very unique in that it’s producing this huge mass of water,” stated Matt Bradford from NASA’s Jet Propulsion Laborator y. “It’s another demonstration that water is pervasive throughout the universe, even at the very earliest times.” Bradford leads one of the teams behind this groundbreaking discovery. Their research, partially funded by NASA, appears in the Astrophysical Journal Letters.
Quasars are powered by enormous black holes that consume surrounding gas and dust, emitting vast amounts of energy. The quasar in question, APM 08279+5255, harbors a black hole 20 billion times more massive than the sun and produces energy equivalent to a thousand trillion suns.
An exploration of the idea of anti-dark matter and quasi stars and other objects that cannot exist in the universe right now, but may in the future and may have in the past.

Have you ever wondered if our universe is more mysterious than we could ever imagine? Some scientists believe that we might be living inside a black hole! This mind-bending idea challenges everything we know about space, time, and the very fabric of reality. Join us as we dive deep into the groundbreaking theories and explore the evidence suggesting that our universe could be the interior of a massive black hole. Learn about the fascinating connection between black holes and the Big Bang, the nature of singularities, and the surprising ways in which physics supports this extraordinary concept. Could the secret to understanding our universe lie within these cosmic giants? Watch now to find out!
And luckily for us, quantum physicists think they know how to reach that higher dimension.
Chinese astronomers have uncovered a low-mass black hole that challenges long-held astrophysical theories. This black hole, part of a binary system known as G3425, has a mass of about 3.6 solar masses, placing it in the elusive mass-gap where black holes were previously thought to be absent. The discovery was made using a combination of radial velo…
