The following is from Interesting Engineering and written by Chris Young. Before we jump into this lets describe what is a gravitational wave. A gravitational wave is an invisible (yet incredibly fast) ripple in space. A Gravitational wave travels at the speed of light (186,000 miles per second). These gravitational waves will squeeze and stretch anything in their path as they pass by. This theory was based on Albert Einstein idea about gravity and space.
Now the above was a theory until scientists using the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) helped to a very loud chorus of gravitational waves emanating throughout the universe. The scientists were studying stars called pulsars that essentially act as cosmic metronomes.
Gravitational waves has been theorized from the first detection of gravitational waves confirming Albert Einstein's theory that they are generated when two massive objects, such as black holes or neutron stars collide.
However with this resent discovery the newly-detected gravitational wave, or ripples in space-time, are the most powerful ever measured. These waves carry roughly a million times the energy of a one-off burst of gravitational waves from a typical black hole or neutron star merger.
In the paper, published in The Astrophysical Journal Letters, the researchers explain that the gravitational waves were likely produced by pairs of supermassive black holes spiraling toward massive collision events.
"It's like a choir, with all these supermassive black hole pairs chiming in at different frequencies," NANOGrav scientist and Yale University professor Chiara Mingarelli, explained in the statement. "This is the first-ever evidence for the gravitational wave background. We've opened a new window of observation on the universe."
"The gravitational wave background is about twice as loud as what I expected," Mingarelli continued. "It's really at the upper end of what our models can create from just supermassive black holes."
The volume may be the result of experimental limitations, though it could also be down to louder and more abundant supermassive black holes than the ones accounted for in the researchers' models. Alternatively, something else that we do not yet understand is generating gravitational waves.
"What's next is everything," Mingarelli said. "This is just the beginning."
How scientists measured the gravitational wave background
The scientists reached their findings using a completely new method. Unlike the Earth-based LIGO and Virgo gravitational wave observatories, which detect high-frequency waves, NANOGrav was designed to measure ultra-low-frequency waves. Some of these waves are so low frequency that a wavelength could be tens of light-years long.
An experiment on Earth wouldn't be able to detect such enormous waves, as these could take decades to pass through a detection facility. Instead, the NANOGrav team closely observed pulsars for many years, which are ultra-dense remnants of large stars that died and went supernova.
Pulsars shoot out beams of radio waves so regularly that they're sometimes referred to as cosmic clocks. For their experiment, the researchers measured the way in which these regular pulses of radio waves were warped by gravitational waves over the course of 15 years.
In total, they analyzed 67 pulsars using the Arecibo Observatory in Puerto Rico, the Green Bank Telescope in West Virginia, and the Very Large Array in New Mexico.
"Pulsars are actually very faint radio sources, so we require thousands of hours a year on the world’s largest telescopes to carry out this experiment," Maura McLaughlin of West Virginia University, co-director of the NANOGrav Physics Frontiers Center explained.
The next step for the NANOGrav scientists will be to pinpoint and analyze sources of the cosmic background noise. By doing so, they may reveal mechanisms of the universe that were previously unknown to humanity.
I have lost a lot of faith with the Medical Community and the Governments over the last several years, but there are a few good things that can raise above the corruption and the pushing of drugs a new approach to heal people. The following is from www.gaia.com and written by Hunter Parsons that does not involve any drug or pushing an ineffective so called vaccine that the drug company is not held accountable in any way but they use sound! The use of sound can regrow bone tissue! Here is the story:
"The future of regenerative medicine could be found within sound healing by regrowing bone cells with sound waves.
The use of sound as a healing modality has an ancient tradition all over the world. The ancient Greeks used sound to cure mental disorders; Australian Aborigines reportedly use the didgeridoo to heal; and Tibetan or Himalayan singing bowls were, and still are, used for spiritual healing ceremonies.
Recently, a study showed an hour-long sound bowl meditation reduced anger, fatigue, anxiety, and ...
Not a fan of a Defense Agency studying Anti-Gravity and other Exotic Tech, but if the commercial world and make this technology cheap that will change our world yet again. The following is about three minute read and from www.gaia.com. The below was written by Hunter Parsons:
"Wormholes, invisibility cloaks, and anti-gravity — it’s not science fiction, it’s just some of the exotic things the U.S. government has been researching.
A massive document dump by the Defense Intelligence Agency shows some of the wild research projects the United States government was, at least, funding through the Advanced Aerospace Threat Identification Program known as AATIP.
And another lesser-known entity called the Advanced Aerospace Weapons System Application Program or AAWSAP
The Defense Intelligence Agency has recently released a large number of documents to different news outlets and individuals who have filed Freedom of Information Act requests.
Of particular interest are some 1,600 pages released to Vice News, which ...
As our technology gets better we are discovering more about the history of mankind and pushing the timeline back further and further. The following article is from www.gaia.com and written by Michael Chary that discusses this new find that changes the historical timeline:
"Over the past decade, there have been a number of archeological revelations pushing back the timeline of human evolution and our ancient ancestors’ various diasporas. Initially, these discoveries elicit some resistance as archeologists bemoan the daunting prospect of rewriting the history books, though once enough evidence is presented to established institutions, a new chronology becomes accepted.
But this really only pertains to the era of human development that predates civilization — the epochs of our past in which we were merely hunter-gatherers and nomads roaming the savannahs. Try challenging the consensus timeline of human civilization and it’s likely you’ll be met with derision and rigidity.
Conversely, someone of an alternative...
Not sure if you have heard of a show on YouTube called "The Why Files". If not you should check it out it is interesting and has some humor with it on different subjects. Last weeks was on a different theory how the Universe works and how main stream Science is attempting to shut it down like is always seems to do if it goes aguest some special interest. Today it is akin to what happened to those who questioned the Earth was the Center of the Universe that main stream so called Science all believed during the Renaissance period, They called any theory that the Earth was not the Center of the Universe misinformation. Does this sound familiar today? People laughed and mocked people like Leonardo da Vinci, Nicolaus Copernicus, Georg Purbach as crack-pots, conspiracy theorists, nut-jobs and they were suppressed and even imprisoned for their radical thoughts and observations. Again it sounds like today in so many ways. In any event this is a good one to ponder and see even if a bad idea ...
Seemingly chaotic systems like the weather and the financial markets are governed by the laws of chaos theory.
We all have heard about chaos theory, but if you have not or have forgotten what chaos theory is well here you go from interestingengineering.com:
"Chaos theory deals with dynamic systems, which are highly sensitive to initial conditions, making it almost impossible to track the resulting unpredictable behavior. Chaos theory seeks to find patterns in systems that appear random, such as weather, fluid turbulence, and the stock market.
Since the smallest of changes can lead to vastly different outcomes, the long-term behavior of chaotic systems is difficult to predict despite their inherently deterministic nature.
As Edward Lorenz, who first proposed what became commonly known as the Butterfly Effect, eloquently said, "Chaos: When the present determines the future, but the approximate present does not approximately determine the future.""
You may have heard the term about chaos theory as a butterfly flaps its wings in Brazil,...
I for one have lost trust in Medical Doctors due to COVID and reflection that they seem to push pills for everything and untested so called vaccines that is using a unproven technology because the Government and the Medical Boards of the State told them to. There are a very few exceptions. Thus they do not address the key problem just prescribe more and more pills to keep you alive an sick longer for them and Big Phama to profit from you. Will AI do any better? Well that depends on what was used for the training of AI. If it also pushes pills and vaccines without question then you have the same problems noted above. However, if the AI Training includes all possible forms of treatment and they zero in on the right issues for the true problem then there is possibilities they would be way better than most of the current Medical Doctors today.
The following is from an article from interestingengineering.com and written by Paul Ratner:
