The Indian astrophysicists used a technique called singular value decomposition method, as against the standard spectral estimation approach that was used in discovering the uniform red shift that supports Big Bang theory. “The superiority of the singular value decomposition method in analysing red shift periodicity, especially from the point of view of robustness, is demonstrated through the simulations. We took very large data samples and used a statistical method, which is more robust than the method usually dealt with by astronomers,” Prof Roy said.

Interestingly, although this is not the first time that the Big Bang theory has been challenged, the previous challenges were based on much smaller sample sizes. The Steady State Theory, Gravitational Lending Model, Tired Photon Hypothesis, Variable Mass Hypothesis have all challenged the Big Bang theory in the past.“But the problem with each of them was the sample size. The renowned physicist, late Stephen Hawking, and his collaborators had stated that the criticism levelled against the theories challenging the Big Bang is because the samples of red shifts that were analysed were rather small and selected in a heterogeneous manner, which made it hard to assess their significance,” Prof Roy said.
 
This also explains why businesses turn people against unions, politicians divide constituents, and one should generally avoid large crowds of people.

I'm a nature nerd. One of my favorite sayings is beware of the herbivores. The Hippo kills more people in Africa than any carnivore.

Mama said that herbivores are so ornery because they have all of those teeth but no toothbrush.
 
 
....Hagfish produce slime the way humans produce opinions—readily, swiftly, defensively, and prodigiously. They slime when attacked or simply when stressed. On July 14, 2017, a truck full of hagfish overturned on an Oregon highway. The animals were destined for South Korea, where they are eaten as a delicacy, but instead, they were strewn across a stretch of Highway 101, covering the road (and at least one unfortunate car) in slime.

Typically, a hagfish will release less than a teaspoon of gunk from the 100 or so slime glands that line its flanks. And in less than half a second, that little amount will expand by 10,000 times—enough to fill a sizable bucket. Reach in, and every move of your hand will drag the water with it. “It doesn’t feel like much at first, as if a spider has built a web underwater,” says Douglas Fudge of Chapman University. But try to lift your hand out, and it’s as if the bucket’s contents are now attached to you.........




 

"Computers have been made with silicon for over 40 years," Gang adds. "It took four decades to push the fabrication down to about 10 nm for planar structures and devices. Now we can make and assemble nanoobjects in a test tube in a couple of hours without expensive tools. Eight billion connections on a single lattice can now be orchestrated to self-assemble through nanoscale processes that we can engineer.

IDK if this is more exciting or terrifying.
 
As much as half of the water in Earth’s oceans could be older than the Sun, a study has found.

By reconstructing conditions in the disk of gas and dust in which the Solar System formed, scientists have concluded that the Earth and other planets must have inherited much of their water from the cloud of gas from which the Sun was born 4.6 billion years ago, instead of forming later. The authors say that such interstellar water would also be included in the formation of most other stellar systems, and perhaps of other Earth-like planets.

The dense interstellar clouds of gas and dust where stars form contain abundant water, in the form of ice. When a star first lights up, it heats up the cloud around it and floods it with radiation, vaporizing the ice and breaking up some of the water molecules into oxygen and hydrogen.......

 
as Carl Sagan said, we are all made of star stuff

and the sugar cube thing is mind blowing
===========================

.......About 99 percent of your body is made up of atoms of hydrogen, carbon, nitrogen and oxygen. You also contain much smaller amounts of the other elements that are essential for life.

While most of the cells in your body regenerate every seven to 15 years, many of the particles that make up those cells have actually existed for millions of millennia. The hydrogen atoms in you were produced in the big bang, and the carbon, nitrogen and oxygen atoms were made in burning stars. The very heavy elements in you were made in exploding stars.

The size of an atom is governed by the average location of its electrons. Nuclei are around 100,000 times smaller than the atoms they’re housed in. If the nucleus were the size of a peanut, the atom would be about the size of a baseball stadium. If we lost all the dead space inside our atoms, we would each be able to fit into a particle of lead dust, and the entire human race would fit into the volume of a sugar cube...........

CAPE CANAVERAL, Fla. (AP) — A piece of the Wright brothers’ first airplane is on Mars.

NASA’s experimental Martian helicopter holds a small swatch of fabric from the 1903 Wright Flyer, the space agency revealed Tuesday. The helicopter, named Ingenuity, hitched a ride to the red planet with the Perseverance rover, arriving last month.

Ingenuity will attempt the first powered, controlled flight on another planet no sooner than April 8. It will mark a “Wright brothers’ moment,” noted Bobby Braun, director for planetary science at NASA’s Jet Propulsion Laboratory.

The Carillon Historical Park in Dayton, Ohio, the Wrights’ hometown, donated the postage-size piece of muslin from the plane’s bottom left wing, at NASA’s request.........
