With the new observations we are seeing a mixture of particle physics being the new physics governing even long standing laws like gravity. Also that string theory is still alive and well. I think we may never know everything unless we essentially get to a type 5 civilization or beyond.

Finding cannot be explained by classical assumptions.

An international team of astrophysicists has made a puzzling discovery while analyzing certain star clusters. The finding challenges Newton’s laws of gravity, the researchers write in their publication. Instead, the observations are consistent with the predictions of an alternative theory of gravity. However, this is controversial among experts. The results have now been published in the Monthly Notices of the Royal Astronomical Society. The University of Bonn played a major role in the study.

Black holes have properties characteristic of quantum particles, a new study reveals, suggesting that the puzzling cosmic objects can be at the same time small and big, heavy and light, or dead and alive, just like the legendary Schrödinger’s cat.

The new study, based on computer modeling, aimed to find the elusive connection between the mind-boggling time-warping physics of supermassive objects such as black holes and the principles guiding the behavior of the tiniest subatomic particles.

Using the IceCube Neutrino Observatory in Antarctica, researchers have found significant evidence of a cosmic source of high-energy neutrinos.

Does the Earth make a sound? Yes! and it’s very eerie!
The European Space Agency (ESA) recently released 5 minutes of haunting, crackling audio. Revealing what Earth’s magnetic field sounds like. Called the Magnetosphere, it is generated deep within the Earth’s interior, at its core. It extends out into space, creating a strong protective shield against things such as charged particles zipping out of the Sun, called the solar wind. And Without this powerful magnetic field, Earth would likely be a barren, cold, dry world. The audio clip you are about to experience might sound like the stuff of nightmares, but sit back, relax and listen to the strange creaking, crackling and rumbling of our planet’s protective shield. This is the sound of the Earth’s magnetic field.

Research from a team of physicists at the University of New Hampshire is advancing the understanding of how protons, which comprise 95% of the mass of the visible universe, interact with each other. The results provide a benchmark for testing the strong force, one of the four fundamental forces in nature.

“There’s a lot still unanswered about both of those things, the proton and the strong force,” said David Ruth, Ph.D. candidate in physics and lead author. “This brings us a little bit closer to that understanding. It’s a necessary piece of two very fundamental things in the universe.”

The strong force governs how what’s internal to the atom’s nucleus—neutrons, protons and the quarks and gluons that make them up—bind together. It is the least understood of the four fundamental forces of nature, which include gravity, electromagnetism and the weak force.

A proposed study of dwarf galaxies could give insight into whether dark matter particles interact with each other.

Thermodynamic phases governed by the strong nuclear force have been linked together using multiple theoretical tools.

Quantum chromodynamics (QCD) is the theory of the strong nuclear force. On a fundamental level, it describes the dynamics of quarks and gluons. Like more familiar systems, such as water, a many-body system of quarks and gluons can exist in very different thermodynamic phases depending on the external conditions. Researchers have long sought to map the different corners of the corresponding phase diagram. New experimental probes of QCD—first and foremost the detection of gravitational waves from neutron-star mergers—allow for a more comprehensive view of this phase structure than was previously possible. Now Tuna Demircik at the Asia Pacific Center for Theoretical Physics, South Korea, and colleagues have put together models originally used in very different contexts to push forward a global understanding of the phases of QCD [1].

Phase transitions governed by the strong force require extreme conditions such as high temperatures and high baryon densities (baryons are three-quark particles such as protons and neutrons). The region of the QCD phase diagram corresponding to high temperatures and relatively low baryon densities can be probed by colliding heavy ions. By contrast, the region associated with high baryon densities and relatively low temperatures can be studied by observing single neutron stars. For a long time, researchers lacked experimental data for the phase space between these two regions, not least because it is very difficult to create matter under neutron-star conditions in the laboratory. This difficulty still exists, although collider facilities are being constructed that are intended to produce matter at higher baryon densities than is currently possible.

The particles inside a proton move around when exposed to electric and magnetic fields, causing it to deform, but this behaviour isn’t well understood.
