The Universe May Have Started with a Dark Big Bang
https://www.universetoday.com/160285/th … -big-bang/
But a team of researchers have proposed a new idea. They argue that our inflation and Big Bang Nucleosynthesis eras were not alone. Dark matter may have evolved along a completely separate trajectory. In this scenario when inflation ended it still flooded the universe with particles and radiation. But not dark matter. Instead there was some quantum field remaining that did not decay away. As the universe expanded and cooled, that extra quantum field did eventually transform itself triggering the formation of dark matter.
The Big Bang may have not been alone. The appearance of all the particles and radiation in the universe may have been joined by another Big Bang that flooded our universe with dark matter particles. And we may be able to detect it.

I normally don't share drama topics but one guy respected in math claims others are 'smoking the ganja' I think our science tv or entertainment world is about to get more 'weird' if it has not already, one name I see pop up is 'Eric' an American hedge fund director and radio podcast host. He is a smart guy and has a PhD in mathematical physics
So here's the thing a lot of Cosmology I personally don't get, sometimes maybe I have a simple childhood understanding of stuff at times maybe I'm not smart enough to get it all and maybe I have my own prejudice I feel most things I need to touch, to bite or feel, to smell and hear or see their chemical effect, I need to look into an engine or look at a visual effect like 'Gravitational Lensing' ...my own bias is I need to see and feel something and not see a conclusion to a math debate or philosophy debate, I have a feeling which in a way is why I am happy to see a Cosmologist call out another Cosmologist but Eric is not a space cosmology guy, he does money and has PhD in mathematical physics . I understand that it can take decades for Special Relativity or Quantum Mechanics to have claims proven but my personal experience with Cosmology is sometimes it is feeling more like a Philosophy than a Real Science.
I am happy to see Cosmology guys ask other Cosmologist people the hard questions, Eric Weinstein understands science but he is not part of this 'Cosmos' fringe club which one day might be confirmed by Hubble, Cern or JWST.
Eric Weinstein even went on the controversial Joe Rogan Experience who has all kinds of fringe ideas, Eric Weinstein already clashed with Brian Greene about foam and strings, they clash over theories of 'everything' he even claims new theories have poisoned physics he wants to see real results, says science has been directionless going in circles and new theory have been leading people in wrong impractical directions for the past decades. He names 'Edward Witten' an American mathematical and theoretical physicist, Professor Emeritus in the School of Natural Sciences at the Institute for Advanced Study in Princeton, a researcher in string theory, quantum gravity, supersymmetric quantum field theories, and other areas of mathematical physics. Witten's work and ideas impacted pure mathematics. The idea of Quantum gravity (QG) field of theoretical physics seeks to describe gravity according to the principles of quantum mechanics. It deals with environments in which neither gravitational nor quantum effects can be ignored, such as in the vicinity of black holes or similar compact astrophysical objects, such as neutron stars.

Lol. Eric Weinstein. "Intellectual Dark Web" guy? Lost his mind, with the rest of them, if he even had it in the first place. Sad tale, but at least it wasn't the best minds of any generation that got destroyed by madness.
Right about physics going in circles maybe. If it's practical stuff you want, the reach is far exceeding our grasp here. There's still a lot of room for development based on what we already know, save the FTL attempts for Gagarin Station.

Is This a Black Hole or a New Type of Star?
https://www.universetoday.com/161084/is … e-of-star/
Within general relativity, black holes are easy to define. They are objects with an event horizon. This horizon is like a line in the sand, where anything crossing it is forever trapped within the black hole. Quantum theory might allow for energy to escape through Hawking radiation, but classical black holes are a one-way trip.

LISA Will Be a Remarkable Gravitational-Wave Observatory. But There’s a Way to Make it 100 Times More Powerful
https://www.universetoday.com/161066/li … -powerful/
The first-time detection of Gravitational Waves (GW) by researchers at the Laser Interferometer Gravitational-wave Observatory (LIGO) in 2015 triggered a revolution in astronomy. This phenomenon consists of ripples in spacetime caused by the merger of massive objects and was predicted a century prior by Einstein’s Theory of General Relativity. In the coming years, this burgeoning field will advance considerably thanks to the introduction of next-generation observatories, like the Laser Interferometer Space Antenna (LISA).
With greater sensitivity, astronomers will be able to trace GW events back to their source and use them to probe the interiors of exotic objects and the laws of physics. As part of their Voyage 2050 planning cycle, the European Space Agency (ESA) is considering mission themes that could be ready by 2050 – including GW astronomy. In a recent paper, researchers from the ESA’s Mission Analysis Section and the University of Glasgow presented a new concept that would build on LISA – known as LISAmax. As they report, this observatory could potentially improve GW sensitivity by two orders of magnitude.
The research was led by theoretical physics Dr. Waldemar Martens, a Mission Analyst at the ESA’s European Space Operations Center (ESOC) in Darmstadt, Germany. He was joined by aerospace engineer and astrophysicist Michael Khan, also a Missions Analyst at the ESOC, and astrophysicist Dr. Jean-Baptiste Bayle, an astronomy and astrophysics Research Fellow with the University of Glasgow. The paper that describes their findings appeared online recently and is currently being reviewed for publication by the journal Classical and Quantum Gravity.

For Mars_B4_Moon re #156
Thank you for the link to this report on a major advance under study, in space based gravitational wave observatory concepts! I was intrigued to learn (for example) that the short baseline of the existing Earth based system cannot pick up events below a certain threshold. Since this is the Physics topic, I'll add that there is at least one publication of a concept for a truly gigantic optical observatory, with detectors spread at the limits of the Solar System. Such a telescope (if every realized) could (theoretically) examine features on the ground of planets in solar systems many light years away.
If faster than light travel proves out of reach for humans, gigantic telescopes on that scale might allow humans to find life elsewhere, and ordinary radio communications would provide a slow but reliable communications pathway.

The findings open up some new possibilities for generating synthetic materials for future technology, said study co-author Prof. David Mazziotti. "A perfect ideal exciton condensate is sensitive and requires a lot of special conditions, but for realistic applications, it's exciting to see something that boosts efficiency but can happen in ambient conditions."

It Might Take Space Telescopes to Finally Resolve the Crisis in Cosmology
https://www.universetoday.com/161779/it … cosmology/
Gravitational wave (GW) observatories have been a great addition to cosmologists’ arsenal in the lack decade. With their first effective detection at the Laser Interferometric Gravitational Observatory completed in 2015, they opened up a whole new world of data collection for scientists. However, so far, they haven’t solved one of the fundamental problems at the heart of their discipline – the “Hubble tension.” Now a new paper discusses the possibility of utilizing a network of new, space-based gravitational wave observatories to get closer than ever to the real value of one of the most important numbers in the Universe.
Anton explains another potential wrinkle in the search for the true Hubble constant – it might not be constant at all.

Physicists discover an exotic material made of bosons
Offline
In following the link provided by Mars_B4_Moon in #165, I found a report on discovery of a state of matter at the quantum level ...
https://phys.org/news/2023-06-experimen … ental.html
The work studied a lattice of electrons and holes separated by an atom scale distance ...
This frustration kicks off the novel chiral edge state, which has a number of surprising characteristics. For instance, if you cool quantum matter in a chiral state down to absolute zero, the electrons freeze into a predictable pattern, and the emergent charge-neutral particles in this state will all either spin clockwise or counterclockwise. Even if you smash another particle into one of these electrons, or you introduce a magnetic field, you can't alter its spin—it's surprisingly robust and can even be used to encode digital data in a fault-tolerant way.
It's tantalizing to suppose that this newly discovered state of matter might be harnessed some day, but the work on quantum computers all over the world provides an incentive.

USTC explored gravity's effect on quantum spins
Offline
In following the link provided by Mars_B4_Moon, about study of gravity and quantum spin, I found another article that caught my eye:
https://www.spacedaily.com/reports/Phot … n_999.html
The meticulous research reported is similar to the quantum vs gravity study, in that the researchers were working with individual particles. In this case, they were working with individual photos, although a lot of them were used in the study.
Details that popped out included:
An estimate that only 1000 solar photons reach an individual chlorophyll molecule in a period of time (which I've already forgotten).
Photons that initiate the photosynthetic reaction are 800 nanometers in wavelength, and the photon emitted after energy is transferred to an electron is 850 nanometers.
I deduce that the entire web of life on Earth arises from that tiny transfer of energy.
The electron set into motion by the single photon triggers a chain of events that lead to formation of simple sugar molecules.
After all, the sun doesn't provide that many photons - only a thousand photons arrive at a single chlorophyll molecule per second on a sunny day - yet the process occurs reliably across the planet.
That was still a question that needed to be answered in detail," said co-lead author Graham Fleming, a senior faculty scientist in the Biosciences Area at Lawrence Berkeley National Laboratory (Berkeley Lab) and professor of chemistry at UC Berkeley.
In their study, Fleming, co-lead author Birgitta Whaley, a senior faculty scientist in the Energy Sciences Area at Berkeley Lab, and their research groups showed that a single photon can indeed initiate the first step of photosynthesis in photosynthetic purple bacteria.

Gravity Waves or a Graviton might not be the realm of scifi after all. From the theories of quantum gravity, the graviton is the hypothetical quantum of gravity, an elementary particle that mediates the force of gravitational interaction. If it exists, the graviton is expected to be massless because the gravitational force has a very long range. Like the force carriers of the other forces such as the photon, gluon, the wave or particle of gravitation also plays a role in general relativity, in defining the spacetime in which cosmological events take place. The gravitational wave is an invisible and incredibly fast ripple in space time. Gravitational Waves are predicted to squeeze and stretch anything in their path as they pass by.
