“Spooky action at a distance” confirmed in heaviest particles
Physicists have delved deeper into the enigmatic world of quantum entanglement and top quarks, bringing a new level of understanding to a phenomenon that even Albert Einstein found perplexing.
This incredible feat has the potential to revolutionize our understanding of the quantum realm and its far-reaching implications.
The experiment, conducted by a team of researchers led by University of Rochester physics professor Regina Demina at the European Center for Nuclear Research (CERN), has yielded a significant result.

Physicists confirm quantum entanglement persists between top quarks, the heaviest known fundamental particles
An experiment by a group of physicists led by University of Rochester physics professor Regina Demina has produced a significant result related to quantum entanglement—an effect that Albert Einstein called “spooky action at a distance.”
What “naked” singularities are revealing about quantum space-time
Are points of infinite curvature, where general relativity breaks down, always hidden inside black holes? An audacious attempt to find out is shedding light on the mystery of quantum gravity.
Dark matter turns out to be an echo of a parallel Universe
The study is based on several intriguing coincidences. First, observations show that there is about the same amount of ordinary and dark matter, which exceeds baryonic by about five times. And secondly, neutrons and protons have almost the same mass, which allows them to form stable atoms — this is a random but stable property of the quantum world, because otherwise our universe would not be home to any of the atoms that make up stars, planets and ourselves.
In fact, the theory suggests that there may be a parallel universe like ours in which neutrons and protons do not have such convenient symmetry in mass. In this world, there is a “soup” of subatomic particles that interact little, which explains why dark matter does not seem to clump together.
It is important to note that this is just one more of many hypotheses that try to explain the mystery of dark matter – an annoying and lingering unknown in our understanding of the universe.
Conservative Black Hole Scattering at Fifth Post-Minkowskian and First Self-Force Order
Quantum field theory techniques are employed to compute the conservative scattering dynamics of a pair of black holes to the fifth order in Newton’s constant.
Fascinating behavior of “super photons” in the quantum realm
Have you ever wondered what happens when thousands of particles of light merge into a single entity? This phenomenon, known as a “super photon,” has fascinated physicists for years.
Now, researchers have made an intriguing discovery that broadens our understanding of this exotic quantum state.
Dr. Julian Schmitt and his colleagues from the Institute of Applied Physics at the University of Bonn have shown that photon Bose-Einstein condensates, also known as quantum gases, obey a fundamental theorem of physics.
A Step toward Quantum Gases of Doubly Polar Molecules
Researchers created an ultracold gas of molecules with strong magnetic dipoles, which may lead to new types of Bose-Einstein condensates.
Quantum data assimilation offers new approach to weather prediction
Data assimilation is a mathematical discipline that integrates observed data and numerical models to improve the interpretation and prediction of dynamical systems. It is a crucial component of Earth sciences, particularly in numerical weather prediction (NWP).
