Imagine a commercial ariline that travels over 4,000 miles per hour, 5 times the speed of sound
Known as hypersonic flight, it requires take-off and landing with a traditional engine.
However, it also requires a specially modified engine, that only ignites after it is already in flight.
Prototypes are soon to come from an Atlanta based company, that has financing from the US government and orders from around the globe. It plans to have a running prototype aircraft by 2023,
a cargo carrying model by 2025 and a passenger model by 2029.
It would allow travel from New York to London in an hour.
It might even allow long distance relationships doable...... at least for the rich.
The plane will carry less than 20 passengers. So, you know those tickets won't be cheap.
Still though, like flights to space, it may foretell what may be common day experiences in the future.

Forget Supersonic. This Hypersonic Jet Can Fly From NYC to London in Under an Hour.

Supersonic flight is arriving—in a hurry. In the last 18 months, Boom has successfully tested its XB-1 demonstrator aircraft and pre-sold 15 of its still-in-development 30-seat Overture models to United Airlines. Virgin Galactic and Rolls Royce rolled out a partnership to develop a 19-seater. Even the Russian Federation revealed plans to build a supersonic jet for commercial use.
Then there’s the Hermeus Quarterhorse. Think supersonic or Mach 1—the speed of sound—multiply by five and you have the hypersonic Quarterhorse.
Last week, the Atlanta-based company announced a $60 million award from the US Air Force to finance testing of the aircraft. Like the Greek god Hermes, this Hermeus is designed to travel seamlessly between worlds, with a projected top speed of Mach 5.5—or 4,219 mph. That makes it the fastest reusable aircraft on the planet, so a New York-to-London flight will take less than an hour.
The speed will come from a unique engine set-up, a turbine-based combined cycle (TBCC) propulsion system. Such systems use a standard jet engine for launch and landing and to build enough speed in flight to feed air into a second turbine—known as a ramjet or scramjet—which produces more power, but requires high-speed air flow in order to ignite. The difficulty is managing the transition between the turbines and achieving the necessary aerodynamics.
Hermeus is off to a good start. In nine months, it designed, built and tested its engine, which is based on GE J85 turbo jet, and it has two advantages when it comes to testing. The Quarterhorse will fly autonomously, so the development team can get prototypes in the air and learn from them without risking pilots’ lives.
Right now, it plans to test a small-scale version in 2023, a mid-size cargo-carrying version in 2025 and a larger commercial passenger version in 2029.
The other advantage is, of course, the government money. “While this partnership with the US Air Force underscores US Department of Defense interest in hypersonic aircraft, when paired with Hermeus’s partnership with NASA announced in February 2021, it is clear that there are both commercial and defense applications for what we’re building,” said AJ Piplica, Hermeus CEO.
Yes, defense is important, but really, let us know when we can wake up in the morning and make it to a late-afternoon tee time at St. Andrews.

Why would anyone lie to gain attention?
So a video has been posted that infers the CEO of Pfizer did not get vaccinated, as usual, it's a crock of lies
I can accept having a vaccine is a personal choice, but when people lie to try and persuade others NOT to have a medically sound vaccine that can and has saved lives, that is just abhorrent to me, just how low will these people sink?
"The interview in which Bourla says he has not gotten vaccinated took place with CNBC on Dec. 14, three days after the U.S. Food and Drug Administration issued the first emergency use authorization for the Pfizer-BioNTech COVID-19 vaccine.
Since the interview, Bourla has been vaccinated, and 28.6% of the U.S. population has received at least one dose and 15.8% have completed vaccination, according to the Centers for Disease Control and Prevention.
"That report is categorically false," Pfizer spokeswoman Sharon Castillo told USA TODAY via email. "Dr. Bourla has been fully vaccinated with the Pfizer-BioNTech vaccine."

THE DULCE AIR BASE
This is the venue of probably the most classified air base on Earth. It extends for 4km underground. It is situated on the Jicarilla Apache Reservation, North Mexico. Claims are that it has a 7 storey underground facility where joint human and alien experiments take place
On 27th July 2023, three military veterans testified in Congress that the US government has operated a secret " multi-decade" reverse engineering program of recovered space vessels, and non-human biologics from crash sites.
Could DULCE be connected to area 51 which has a top secret reputation?

NUCLEAR FUSION
One of the constituents of nuclear fusion is helium-3. This material is rare on this planet, but apparently is abundant on the moon. Nuclear fusion is what makes the sun function. The challenge is to recreate this form of energy and in doing so, could produce a cleaner and environmentally friendly and constant source of power. Research is advancing on this energy, but you can understand why some countries find reaching the moon important. Mining for helium-3 is no doubt a big objective.
Oh Venus !
Named after a goddess of beauty, Venus is our closest neighbor in the solar system and thanks to reflected sunlight, one of the brightest points of light in the night sky.
Because the surface of that planet is very hot and considered inhospitable to life, it has not been the focus of our unending search for other life in the universe. Indeed, attempts to explore the planet have not been very fruitful, as even metals melt upon arrival.
However, at one ancient time, Venus may have been more teeming with life than Earth was at that time. Hundreds of millions of years ago, Venus had oceans. Perhaps it may even today have some life remaining. Astronomers recently found a lot of phosphine within the clouds around Venus. Some rule out other sources of the biomolecule and conclude, that it must be actively produced by microorganism(s) within the clouds. Indeed, since sunlight breaks down phosphine, there must be some current active source. Of course, some others believe otherwise. Nonetheless, life may be much closer, than most predicted. Venus may once again become an area of interest.

Life on Venus? Astronomers See a Signal in Its Clouds
The detection of a gas in the planet’s atmosphere could turn scientists’ gaze to a planet long overlooked in the search for extraterrestrial life.
By Shannon Stirone, Kenneth Chang and Dennis Overbye
Sept. 14, 2020 Updated 11:19 a.m. ET
High in the toxic atmosphere of the planet Venus, astronomers on Earth have discovered signs of what might be life.
If the discovery is confirmed by additional telescope observations and future space missions, it could turn the gaze of scientists toward one of the brightest objects in the night sky. Venus, named after the Roman goddess of beauty, roasts at temperatures of hundreds of degrees and is cloaked by clouds that contain droplets of corrosive sulfuric acid. Few have focused on the rocky planet as a habitat for something living.
Instead, for decades, scientists have sought signs of life elsewhere, usually peering outward to Mars and more recently at Europa, Enceladus and other icy moons of the giant planets.
The astronomers, who reported the finding on Monday in a pair of papers, have not collected specimens of Venusian microbes, nor have they snapped any pictures of them. But with powerful telescopes, they have detected a chemical — phosphine — in the thick Venus atmosphere. After much analysis, the scientists assert that something now alive is the only explanation for the chemical’s source.
Some researchers question this hypothesis, and they suggest instead that the gas could result from unexplained atmospheric or geologic processes on a planet that remains mysterious. But the finding will also encourage some planetary scientists to ask whether humanity has overlooked a planet that may have once been more Earthlike than any other world in our solar system.
“This is an astonishing and ‘out of the blue’ finding,” said Sara Seager, a planetary scientist at the Massachusetts Institute of Technology and an author of the papers (one published in Nature Astronomy and another submitted to the journal Astrobiology). “It will definitely fuel more research into the possibilities for life in Venus’s atmosphere.”
“We know that it is an extraordinary discovery,” said Clara Sousa-Silva, a molecular astrophysicist at Harvard University whose research has focused on phosphine, and another of the authors. “We may not know just how extraordinary without going back to Venus.”.....

PETER HIGGS DIED 8th APRIL 2024
HIGGS was the scientist who believed in a substance that would enable light to be converted to matter. So, in the beginning of creation of all elements there must have been something to enable matter to be formed.
The Hadron collider confirmed the existence of such a substance and Higgs name was given to it, hence the Higgs boson.
A simple explanation, I know. A boson is a sub atomic particle.

Shit happens
A Queensland camper has made a momentous scientific discovery after taking a closer look at a hairy poo.
Entomologist James Tweed was chilling out in the lush rainforest that sits behind the Gold Coast's busy beaches a while back.
As he wandered off to clean his teeth, his gaze fell upon what he thought was a blob of bird poo, turning furry with mould in the humidity.
But it turned out to be Australia's newest creepy-crawly – a longhorn beetle so distinct from its relatives that it's not just a new species, but a whole new genus.

An Ancient frog species named after Kermit the Frog by scientists
Kermit the Frog has been around since 1955 – but a new Kermit on the block was actually around much longer ago.
Scientists have uncovered a fossil of an ancient 270-million-year-old amphibian ancestor, and named it after him.

Case definition...and science...
......Real science...VERY real. I know, I know, just how tedious I can be when I put on my real Teacher/Scientist fat Runt hat, VERY real, so I'll try to be brief.
Let's say you are doing biology with animals, plants or microbes. When you try to get funding, or to publish findings, the first levels of scrutiny involve spot on valid identification of your study/experimental, VERY MENTAL, models.
Recently, some of our family reflected on this with Dad, describing how much effort is put into exact characterization of mouse stem cell lines, by these hard working Interns at an international standards genetics research outfit. Selective breeding, DNA\RNA verification of cell cultures, yep---the whole nine yards.
So it is in studying various aspects of human health and illness. Enter the topic of valid case identification. Of course, for myriad reasons in free living human populations, the exact laboratory measures mentioned above can only be approximated, which of course dilutes things when it comes to sadistical analyses. It ain't a perfect world, peebles
So we hear about about how politics, once again, can slither into science. Worse, when big bucks are involved.
Apparently, on the data charts when patients are admitted to Horsepital, there's usually a little field for checking off, labelled as "Covid-19 Case?". If someone is admitted for any cause, and proper care involves being placed on a respirator, along with other information, checking off this field on a clinical hunch, involves more reimbursement for the Hospital from government, and even private insurance. Increase in billing can range from $11,000 to $39,000. Many people WITHOUT C-19 are placed on respirators.
Remember this every time that we hear of reported numbers of Cases/Death of C-19.
