NASA's Hubble Space Telescope Just Detected a Possible Roaming Black Hole Out in the Milky Way
https://www.yahoo.com/entertainment/nas … 32380.html
Black holes and neutron stars both occur after a star explosion. (Roaming black holes will appear after a huge star explosion, though.) This discovery overall is notable, particularly because of how it was uncovered. "This is the first free-floating black hole or neutron star discovered with gravitational microlensing," Lu said in the statement. "With microlensing, we're able to probe these lonely, compact objects and weigh them. I think we have opened a new window onto these dark objects, which can't be seen any other way."

The 5 types of BLACK HOLES

Types of black holes explained
https://www.youtube.com/watch?v=v4bTZR5t3CU
'In general relativity, a white hole is a theoretical region of spacetime and singularity that cannot be entered from the outside, although energy-matter, light and information can escape from it. The reverse of a black hole, which can be entered only from the outside and from which energy-matter, light and information cannot escape. White holes appear in the theory of eternal black holes.'

Most Black Holes Spin Rapidly. This one… Doesn’t
That is interesting. I do wonder how spin can have any relevance to an object that is behind an event horizon. How would we ever know if a singularity is spinning? Without any surface features, a rotating black hole cannot generate tidal effects by its spin.

Hubble Sees a Mirror Image of the Same Galaxy Thanks to Gravitational Lensing
https://www.universetoday.com/156878/hu … l-lensing/
However perhaps a poor use of language, duplicated images of the actual object "behind" the galaxy, sometimes three or more images are copied but not always from the exact same point in time?
Looking through a wine glass the image of the world behind will also be distorted but are they truly "mirrored" galaxies?

Making Muons for Scientific Discovery, National Security
https://www.spacedaily.com/reports/Maki … y_999.html
The Defense Department and other federal agencies have sought advanced sources that generate gamma rays, X-rays, neutrons, protons, and electrons to enable a variety of scientific, commercial, and defense applications - from medical diagnostics, to scans of cargo containers for dangerous materials, to non-destructive testing of aircraft and their parts to see internal defects. But none of these sources can image through concrete walls several meters thick, map the core of a volcano from the outside, or peer deep underground to locate chambers and tunnels. For such imaging capabilities, a more powerful particle is needed.
DARPA's Muons for Science and Security program (MuS2 - pronounced Mew-S-2) aims to create a compact source of deeply penetrating subatomic particles known as muons. Muons are similar to electrons but about 200 times heavier. At high energy, muons can travel easily through dozens to hundreds of meters of water, solid rock, or soil. Producing muons, however, is a challenge, because it requires a very high-energy, giga-electronvolt (GeV) particle source. Currently, two primary sources for muons exist. Cosmic ray interactions in the upper atmosphere naturally generate muons as they descend to Earth in created particle showers.
Harnessing these muons for imaging is tedious and not very practical. Cosmic muons have played a role in special projects, such as when scientists used them to image interior chambers of the great pyramids in Egypt. Given the small number of muons that reach the Earth's surface and the divergent paths they travel through the atmosphere, it can take days to months to capture enough muon data to produce meaningful results.
Muons can also be generated terrestrially. But making muons requires such high-energy particles that production is limited to large physics research facilities such as the United States' Fermilab national particle accelerator in Illinois and the European CERN accelerator in Switzerland.
"Our goal is to develop a new, terrestrial muon source that doesn't require large accelerators and allows us to create directional beams of muons at relevant energies, from 10s to 100s of GeVs - to either image or characterize materials," said Mark Wrobel, MuS2 program manager in DARPA's Defense Sciences Office.

Black hole 'superradiance' phenomenon may aid quest for dark matter
https://www.space.com/black-hole-superr … er-photons
The superradiance process is unstable. Over incredibly long timescales, enough photons can get boosted to high enough energies that the entire surroundings of the black hole turn into a giant "bomb," with the trapped photons blasting away in a single gigantic burst. But this process happens slowly enough that we haven't seen it play out in the universe yet.
Superradiance can extend beyond photons; it can happen to any kind of boson, including all the force carriers of nature and the Higgs boson — and also, maybe, dark matter.
Dark matter is the dominant form of matter in the universe, making up over 80% of all the mass of every galaxy and cluster. Astronomers have troves of circumstantial evidence for the existence of dark matter but have yet to pin down its identity.
One possibility is that dark matter is a new kind of ultralight particle that shares a lot of characteristics with bosons but does not interact with all the normal particles in the universe. These "dark photons" would be incredibly light yet absolutely flood the cosmos. But because they would not interact with normal matter, they would be exceedingly difficult to observe directly.

Evidence of 3 Never-Before-Seen Particles
https://www.sciencealert.com/large-hadr … -particles
The Large Hadron Collider smashes protons together at velocities close to the speed of light to study combinations of quarks that are known as hadrons.
"The more analyses we perform, the more kinds of exotic hadrons we find," Niels Tuning, physics coordinator for the collider's LHCb detector, said in a news release.
"We're witnessing a period of discovery similar to the 1950s, when a 'Particle Zoo' of hadrons started being discovered and ultimately led to the quark model of conventional hadrons in the 1960s. We're creating 'Particle Zoo 2.0'."
LHCb spokesperson Chris Parkes said studying new combinations of quarks "will help theorists develop a unified model of exotic hadrons, the exact nature of which is largely unknown".
Most hadrons aren't so exotic. Protons and neutrons, for instance, are made up of three quarks bound together. (In fact, the origin of the word "quark" goes back to a line from Finnegan's Wake by James Joyce: "Three quarks for Muster Mark!") Pions are two-quark combinations.
Four-quark and five-quark combinations are much rarer, and are thought to exist for only an instant before decaying into different types of particles.
Quarks come in six different "flavors": up and down, top and bottom, charm and strange.
The LHCb team analyzed the decays of negatively charged B mesons and saw evidence for the existence of a pentaquark consisting of a charm quark and a charm antiquark, plus an up, down and strange quark. It's the first pentaquark known to include a strange quark.
The two newly identified tetraquarks include a "doubly electrically charged" combination of four quarks: a charm quark, a strange antiquark, an up quark, and a down antiquark.
That tetraquark was spotted in combination with its neutral counterpart, which has a charm quark, a strange antiquark, an up antiquark, and a down quark. CERN says this is the first time a pair of tetraquarks has been observed together.
Some theoretical models visualize exotic hadrons as single units of tightly bound quarks. Others see them as pairs of standard hadrons that are loosely bound together, similar to the way that atoms are bound together to form molecules.
"Only time and more studies of exotic hadrons will tell if these particles are one, the other or both," CERN says.

The Complex Field Theory and Mass Formation—An Alternative Model to Higgs Mechanism
https://scirp.org/reference/referencesp … id=3459397
An axion a hypothetical elementary particle postulated by the Peccei–Quinn theory in 1977 to resolve the strong CP problem in quantum chromodynamics (QCD). If axions exist and have low mass within a specific range, they are of interest as a possible component of cold dark matter.
With a mass above 10−11 times the electron mass (5 µeV/c²) axions could account for dark matter, and thus be both a dark-matter candidate and a solution to the strong CP problem. If inflation occurs at a low scale and lasts sufficiently long, the axion mass can be as low as 1 peV/c².
Despite not yet having been found, axion models have been well studied for over 40 years, giving time for physicists to develop insight into axion effects that might be detected. Several experimental searches for axions are presently underway; most exploit axions' expected slight interaction with photons in strong magnetic fields. Axions are also one of the few remaining plausible candidates for dark matter particles, and might be discovered in some dark matter experiments.
Dark Energy is an unknown form of energy that affects the universe on the largest scales. The first observational evidence for its existence came from measurements of supernovas, which showed that the universe does not expand at a constant rate; rather, the universe's expansion is accelerating

Chargino the heavier chargino can decay through the neutral Z boson to the lighter chargino. Both can decay through a charged W boson to a neutralino the neutralino a hypothetical particle four states are composites of the bino and the neutral wino, gluino the hypothetical supersymmetric partner of a gluon, Squarks also quarkinosare the superpartners of quarks, Sleptons are the superpartners of leptons, leptoquarks are predicted by GUT theories to be heavier equivalents of the W and Z bossons and X17 particle is a hypothetical subatomic particle proposed by Attila Krasznahorkay and his colleagues to explain certain anomalous measurement results particle seems to be an explain all bad results new particle fix and could be the force carrier for a postulated fifth force, possibly connected with dark matter, 'Eric Weinstein' is a controversial figure he is not as smart as other theoretical physicists, he maybe went too far with language and called others out by name but perhaps he is right to call out modern physics when he accuses it of 'going in circles'.
Or maybe we will understand one day and see all these 11 Dimensions, the idea of a Higgs Boson Elementary particle or Gravity Waves was once thought ridiculous.

Eric Weinstein has clashed with Brian Greene and also called out 'Edward Witten' but has admitted he is afraid to debate him, Witten's work has significantly impacted pure mathematics. He became the first physicist to be awarded a Fields Medal by the International Mathematical Union, for his mathematical insights in physics, such as his 1981 proof of the positive energy theorem in general relativity, and his interpretation of the Jones invariants of knots as Feynman integrals. He is considered the practical founder of M-theory.

Throughout his life, Witten has been awarded with some top honors from various sources. Some of the most notable awards include the Albert Einstein Award in 1985, which is awarded to theoretical physicists and is just as prestigious as the Nobel Prize. In 2002, he won the National Medal of Science, an award that is given by the President of the United States to individuals who have made significant and important findings that contribute to the understanding of science and related subjects.
Other awards that Witten has received include the Harvey Prize in 2005 for individuals who make contributions to science and related subjects. In 2010, he won the Isaac Newton Medal and two years later, he won the Fundamental Physics Prize, which is also known as the Russian Nobel Prize because it was created by Yuri Milner, a Russian physicist.
