Interesting article I came across, and which I find appropriate particularly with the undeserved and mostly invalidated criticism leveled at science, by many "would be's if they could be's" out there....My question is highlighted at the end of the two articles........ In Praise of Scientific Theory Just a hunch? Hardly. Think germ theory, atomic theory and the theory of evolution. Science can make life difficult for manipulators and demagogues. Without science, it would be much easier to convince the public that an intelligent designer created the world, or that greenhouse gas warming and lead contamination are just the fantasies of “alarmists.” To physicis…

https://phys.org/news/2018-11-spacetimea-creation-well-known-actors.html Spacetime—a creation of well-known actors? November 9, 2018, The Henryk Niewodniczanski Institute of Nuclear Physics Polish Academy of Sciences: Most physicists believe that the structure of spacetime is formed in an unknown way at the Planck scale, i.e., at a scale close to one trillionth of a trillionth of a metre. However, careful considerations undermine this prediction. There are quite a few arguments in favour of the emergence of spacetime as a result of processes taking place at the level of quarks and their conglomerates.What is spacetime? The absolute, unchanging arena of even…

http://www.pnas.org/content/104/suppl_1/8567 Darwin's greatest discovery: Design without designer: Abstract: Darwin's greatest contribution to science is that he completed the Copernican Revolution by drawing out for biology the notion of nature as a system of matter in motion governed by natural laws. With Darwin's discovery of natural selection, the origin and adaptations of organisms were brought into the realm of science. The adaptive features of organisms could now be explained, like the phenomena of the inanimate world, as the result of natural processes, without recourse to an Intelligent Designer. The Copernican and the Darwinian Revolutions …

What emerges is a deeply human trip to the foundations …

The disputed article......https://phys.org/news/2016-09-oldest-fossils-life-young-earth.html Oldest fossils point to thriving life on young Earth September 1, 2016 Australian researchers have found the world's oldest fossils, revealing that diverse life forms thrived on Earth 3.7 billion years ago. Co-lead investigator Associate Professor Vickie Bennett from The Australian National University (ANU) said the research on stromatolite fossils found in Greenland provided a greater understanding of early habitats of life on Earth and could have implications for searching for life on Mars. "This discovery turns the study of planetary habitability on it…

https://phys.org/news/2018-10-milky-life-star.html For almost two centuries, scientists have theorized that life may be distributed throughout the universe by meteoroids, asteroids, planetoids, and other astronomical objects. This theory, known as Panspermia, is based on the idea that microorganisms and the chemical precursors of life are able to survive being transported from one star system to the next. Expanding on this theory, a team of researchers from the Harvard Smithsonian Center for Astrophysics (CfA) conducted a study that considered whether panspermia could be possible on a galactic scale. According to the model they created, they determined that the …

https://www.sciencedaily.com/releases/2018/10/181014142709.htm extract: Physicists send a beam of either electrons, protons, or a laser through a plasma. Free electrons in the plasma move toward the beam, but overshoot it, then come crashing back, creating a bubble structure behind the beam and intense electric fields. If you inject particles, like more electrons, into the wake, it can accelerate the injected particles in a shorter amount of time with an electric field 10 or more times stronger. In the study, proton-driven plasma wakefield acceleration has been demonstrated for the first time. The strong electric fields, generated by a series of prot…

https://phys.org/news/2018-10-massive-star-unusual-death-heralds.html Massive star's unusual death heralds the birth of compact neutron star binary October 11, 2018, Carnegie Institution for Science The three panels represent moments before, when and after the faint supernova iPTF14gqr, visible in the middle panel, appeared in the outskirts of a spiral galaxy located 920 million light years away from us. The massive star that died in the supernova left behind a neutron star in a very tight binary system. These dense stellar remnants will ultimately spiral into each other and merge in a spectacular explosion, giving off gravitational and electrom…

https://phys.org/news/2018-10-era-quest-dark.html Since the 1970s, astronomers and physicists have been gathering evidence for the presence in the universe of dark matter: a mysterious substance that manifests itself through its gravitational pull. However, despite much effort, none of the new particles proposed to explain dark matter have been discovered. In a review that was published in Nature this week, physicists Gianfranco Bertone (UvA) and Tim Tait (UvA and UC Irvine) argue that the time has come to broaden and diversify the experimental effort, and to incorporate astronomical surveys and gravitational wave observations in the quest for the nature of dark matt…

https://phys.org/news/2018-10-high-scandium-galaxy-giant-black.html High levels of scandium near the galaxy's giant black hole were illusory, astronomers find October 10, 2018, Lund University Astronomers from Lund University in Sweden have now found the explanation to a recent mystery at the centre of the Milky Way galaxy: the high levels of scandium discovered last spring near the galaxy's giant black hole were in fact an optical illusion. Last spring, researchers published a study about the apparent presence of astonishing and dramatically high levels of three different elements in red giant stars, located less than three light years away …

https://www.technology.org/2018/10/06/parker-solar-probe-changed-the-game-before-it-even-launched/ On Oct. 3, 2018, Parker Solar Probe performed the first significant celestial maneuver of its seven-year mission. As the orbits of the spacecraft and Venus converged toward the same point, Parker Solar Probe slipped in front of the planet, allowing Venus’ gravity — relatively small by celestial standards — to twist its path and change its speed. This maneuver, called a gravity assist, reduced Parker’s speed relative to the Sun by 10 percent — amounting to 7,000 miles per hour — drawing the closest point of its orbit, called perihelion, nearer to the star by 4 million mi…

No, not really........https://www.technology.org/2018/10/08/new-image-shows-the-rugged-landscape-of-comet-67p/ Comet 67P Rugged Landscape Shown on a New Image Posted Yesterday In March of 2004, the European Space Agency’s Rosetta spacecraft blasted off from French Guiana aboard an Ariane 5 rocket. After ten years, by November of 2014, the spacecraft rendezvoused with its target – Comet 67P/Churyumov-Gerasimenko (67P/C-G). Over the more than two years that followed, the spacecraft remained in orbit of this comet, gathering information on its surface, interior, and gas and dust environment. And on September 30th, 2016, Rosetta came closer than ever t…

https://phys.org/news/2018-09-astronomers-witness-birth-star-stellar.html Astronomers witness birth of new star from stellar explosion September 12, 2018, Purdue University The explosions of stars, known as supernovae, can be so bright they outshine their host galaxies. They take months or years to fade away, and sometimes, the gaseous remains of the explosion slam into hydrogen-rich gas and temporarily get bright again—but could they remain luminous without any outside interference? That's what Dan Milisavljevic, an assistant professor of physics and astronomy at Purdue University, believes he saw six years after "SN 2012au" exploded. Read more at: h…

Since publication of this story, CERN has suspended Alessandro Strumia from any activities, pending an investigation. A physicist speaking at CERN, the home of the Large Hadron Collider in Geneva, has sparked outrage after claiming that women are less capable of physics research. Alessandro Strumia at the University of Pisa, Italy, was speaking to an audience of women beginning their careers in science at a CERN workshop on gender and high energy physics. He gave a talk claiming that the reason men are so over-represented in the field of physics is because they are “over-performing”, and that physics was “invented and built by men”.

In a paper published Oct. 3 in the journal Science Advances, Alex Teachey and David Kipping report that the detection of a candidate exomoon—that is, moons orbiting planets in other star systems—is unusual because of its large size, comparable t…

A Canadian ( U of Waterloo, originally from Guelph ) woman, Donna Strickland, is only the third woman ever ( first in 1903, second was back in 1963 ) to be awarded the Nobel prize in Physics for her work in high energy lasers. The methods she helped develop while doing her PhD in the 80s, 'chirped pulse amplification', reconciles the requirements for short pulses and high power ( without blowing up the laser ). Especially significant for me; she is my age , so we probably attended ( different ) Universities at the same time. Glad that the Nobel Committee is recognizing women's accomplishments in Physics. ( but do they need to wait 60 yrs in between ? )

An expedition to the Atacama Trench has uncovered a wealth of information. They found three new fish species. They do not conform to the preconceived stereotypical image of what a deep-sea fish should look like. Instead of giant teeth and a menacing frame, the fishes that roam in the deepest parts of the ocean are small, translucent, bereft of scales—and highly adept at living where few other organisms can. https://phys.org/news/2018-09-species-fish-extreme-depths-pacific.html#jCp

It is an Atheist Forum, where arrogance and condescension rule. Opinions and facts presented which are contrary to the diktats of Swansont are summarily deleted, with malice. He has a faint orgasm every time he bans someone who doesn't speak and write in accordance with his own views. This is my final post. I am self-banning, denying Mister Petty Atheist the chance to meaningfully ban me.
