  • Can Matter Be Eternal and Created at the Same Time?

    04/13/2015 2:37:54 PM PDT · by NYer · 53 replies
    Aleteia ^ | April 13, 2015 | WILLIAM E. CARROLL
    Does it matter whether or not matter is eternal? Peter J. Leithart, who writes a regular blog on the web site of First Things, definitely thinks it does. According to Leithart , who is a Protestant theologian in the Reformed Presbyterian tradition in the United States, if matter is eternal, "creation can only be control, limitation, ordering." Then God could only be a master craftsman, working with already existing material to form the universe. If matter is eternal, "creation cannot be a gift; . . . cannot be the bestowal of existence, a grant of being." Finally, if matter is...

    Based on the latest evidence and theories our galaxy could be a huge wormhole (or space-time tunnel, have you seen the movie "Interstellar?") and, if that were true, it would be "stable and navigable." This is the hypothesis put forward in a study published in Annals of Physics and conducted with the participation of SISSA in Trieste. The paper, the result of a collaboration between Indian, Italian and North American researchers, prompts scientists to re-think dark matter. "If we combine the map of the dark matter in the Milky Way with the most recent Big Bang model to explain the...

    Physicists Resurrect an Old, ‘Strange’ Dark Matter Theory Written by Michael Byrne Editor November 5, 2014 // 09:15 AM EST Dark matter might not be nearly as exotic as most theories about the stuff suggest. Instead, it could be macroscopic clumps of material formed from common particles already found within the Standard Model of particle physics. This argument comes courtesy of physicists at Case Western University, as presented in a new paper posted to the arXiv pre-print server. Dark matter is usually thought of in terms of exotic, so-far undiscovered particles. The leading candidates are known as weakly interacting massive particles,...

    The new Majorana particle showed up inside a superconductor, a material in which the free movement of electrons allows electricity to flow without resistance. The research team, led by Ali Yazdani of Princeton University, placed a long chain of iron atoms, which are magnetic, on top of a superconductor made of lead. Normally, magnetism disrupts superconductors, which depend on a lack of magnetic fields for their electrons to flow unimpeded. But in this case the magnetic chain turned into a special type of superconductor in which electrons next to one another in the chain coordinated their spins to simultaneously satisfy...

Concerned citizens lobbied Southern Utah University president Scott Wyatt months ago for the change, but he has only now decided to remove the name out of respect for the Senate majority leader, Utah’s The Spectrum reports. “I didn’t want to offend him in any way,” he explained. Cedar City Councilman Paul Cozzens told The Specter he received $40,000 in pledges to remove the Nevada senator’s name in just five days. “These people...

    Imperial College London physicists have discovered how to create matter from light - a feat thought impossible when the idea was first theorised 80 years ago. In just one day over several cups of coffee in a tiny office in Imperial's Blackett Physics Laboratory, three physicists worked out a relatively simple way to physically prove a theory first devised by scientists Breit and Wheeler in 1934.Breit and Wheeler suggested that it should be possible to turn light into matter by smashing together only two particles of light (photons), to create an electron and a positron – the simplest method of...

Harvard and MIT scientists are challenging the conventional wisdom about light, and they didn't need to go to a galaxy far, far away to do it. Working with colleagues at the Harvard-MIT Center for Ultracold Atoms, a group led by Harvard Professor of Physics Mikhail Lukin and MIT Professor of Physics Vladan Vuletic have managed to coax photons into binding together to form molecules – a state of matter that, until recently, had been purely theoretical.

    One physicist says he likes this theory because of “its simplicity, uniqueness and the fact that it can be tested.”Theoretical physicists at Vanderbilt University contend that a simply theory may explain mysterious dark matter. They propose that most of the matter in the universe may be constructed of particles that have an abnormal, donut-shaped electromagnetic field known as an anapole. According to a news release from Vanderbilt University, Professor Robert Scherrer and post-doctoral fellow Chiu Man Ho carried out an in-depth analysis to determine the validity of this theory. Scherrer points out that he likes this theory because of “its...

    Two years ago several of my Sci Am colleagues and I had an intense email exchange over a period of weeks, trying to figure out what to make of a new paper by string theorist Erik Verlinde. I don’t think I’ve ever been so flummoxed by physicists’ reactions to a paper. Mathematically it could hardly have been simpler—the level of middle-school algebra for the most part. Logically and physically, it was a head-hurter. I couldn’t decide whether it was profound or trite. The theorists we consulted said they couldn’t follow it, which we took as a polite way of saying...

    In a paper published in the March 29 issue of the journal Nature, the scientists describe the emergence of “spontaneous coherence,” “spin textures” and “phase singularities” when excitons—the bound pairs of electrons and holes that determine the optical properties of semiconductors and enable them to function as novel optoelectronic devices—are cooled to near absolute zero. This cooling leads to the spontaneous production of a new coherent state of matter which the physicists were finally able to measure in great detail in their basement laboratory at UC San Diego at a temperature of only one-tenth of a degree above absolute zero....

    A new study has shown why the lights are going out in the Universe. The Universe forms fewer stars than it used to, and a CSIRO study has now shown why - the galaxies are running out of gas. Dr Robert Braun (CSIRO Astronomy and Space Science) and his colleagues used CSIRO’s Mopra radio telescope near Coonabarabran, NSW, to study far-off galaxies and compare them with nearby ones. Light (and radio waves) from the distant galaxies has taken time to travel to us, so we see the galaxies as they were between three and five billion years ago. Galaxies at...
  • Could "Mirror Matter" Be the Hidden Mass that Holds the Universe Together?

    08/03/2011 5:15:38 AM PDT · by LibWhacker · 15 replies
    If dark matter exists it may take the form of mirror planets, mirror stars and mirror galaxies. Now one physicist says the most recent evidence seems to confirm this idea. When astronomers study distant galaxies, they see only a small fraction of the mass needed to hold these clumps of stars together. Without some kind of extra hidden mass, galaxies ought to fly apart. Astronomers call this hidden mass 'dark matter' and physicists around the world are engaged in an increasingly desperate race to find evidence of it here on Earth. The main possible candidates include MACHOS and WIMPS, but...

Only now, for example, are we seeing the devastation caused by the last Oval Office infestation. Like Barack Obama, Bill Clinton also campaigned as a moderate. Once elected, however, he surrounded himself with some of the most radical leftists ever appointed to the Cabinet. (Many of them have re-enlisted with this administration.) Behind the scenes, they worked furiously to undermine the system. And now, decades later, we're seeing the results. Clinton's policies — not just his unethical conduct — were recipes for disaster.

    Astronomers have found a piece of the universe's puzzle that's been missing for awhile: a type of extremely hot, dense matter that is all but invisible to us. Engaging in something like cosmic accounting, astronomers have tried to balance the scant amount of matter that has been directly observed with the vast amount that remains unobserved directly. The latter constitutes about 90 percent of the universe's matter. Galaxies, the stars within them, the planet we live on and the chairs we sit on are made up of normal matter — the protons, electrons and neutrons that are collectively called baryons....

    The first stars to appear in the Universe may have been powered by dark matter, according to US scientists. Normal stars are powered by nuclear fusion reactions, where hydrogen atoms meld to form heavier helium. But when the Universe was still young, there would have been abundant dark matter, made of particles called Wimps: Weakly Interacting Massive Particles. These would have fused together and obliterated each other long before nuclear fusion had the chance to start. As a result, the first stars would have looked quite different from the ones we see today, and they may have changed the course...

    Beamish and Day are the only researchers in Canada conducting experimental research in this area of fundamental physics. At very low temperatures, helium gas turns into a liquid. Put under extreme pressure the liquid turns into a solid. Physicists have been manipulating solid helium so they can study its unusual behaviour. In 2004, a research team at Penn State university in the United States, led by Dr. Moses Chan, electrified the physics world when it announced that it may have discovered an entirely new state of matter - supersolidity. The team made the discovery by cooling solid helium to an...
  • Out Among the Dark Stars

    You would think that a star anywhere from 400 to 200,000 times wider than the Sun would be fairly easy to detect. But not if it’s a ‘dark star,’ the name for a new, theoretical entity about to make its appearance in Physical Review Letters. Astrophysicist Paolo Gondolo (University of Utah) makes the case that dark matter would have affected the temperature and density of the gases that formed the first stars. Dark stars would mostly contain normal matter — hydrogen and helium — but they would have been much larger than the Sun, glowing largely in the infrared. Hypothetical...

    Astronomers have discovered a chaotic scene unlike any witnessed before in a cosmic "train wrecK" between giant galaxy clusters. NASA's Chandra X-ray Observatory and optical telescopes revealed a dark matter core that was mostly devoid of galaxies, which may pose problems for current theories of dark matter behavior.

    We exist, therefore we question. Or at least, that paraphrases (poorly) an old quote from an old scholar... We know the masses and general composition of the four inner (rocky) planets in our solar system, and from basic chemistry, we know the number of atoms in a gram of any material. Multiplying Avogadro's number x the mass of these four planets, dividing by a weighted average atomic weight for the materials in each planet, we get about 3 x 10^ 50 heavy nuclei produced since creation/the big bang. Take your pick, that's the number of atomic nuclei we have to...

    Caption: Fig. 1: Image of the mass distribution over a patch of sky about one quarter of the area of the Full Moon. These images were made by PhD student Stefan Hilbert using the Millennium Simulation, the largest computer simulation of cosmic structure formation ever carried out. The left panel represents the kind of image which could be made by a low-frequency radio telescope with a diameter of 100 kilometres, using the gravitational distortion of images of pregalactic structure in the neutral hydrogen distribution. The right panel represents the kind of image which could be made for the same region...

    This thread is a continuation of the first thread "Questions For Atheists & Non-Atheists" Some points were brought up that I wish to address here. I look forward to the responses. Taken from one of my dictionaries in my personal library: "Occam's Razor. A principle devised by the English philospher William of Occam, which states that entities must not be multiplied beyond what is necessary. In a scientific context, Occam's Razor is the choice of the simplest theory from among the theories which fit what we know. In logic, Occam's Razor is the statement of an argument in its essential...

    Antimatter and matter combine in chemical reaction 19:47 13 October 2006 NewScientist.com news service Stephen Battersby Mixing antimatter and matter usually has predictably violent consequences – the two annihilate one another in a fierce burst of energy. But physicists in Geneva have found a new way to make the two combine, at least briefly, into a single substance. This exceptionally unstable stuff, made of protons and antiprotons, is called protonium. The feat of "antichemistry" actually took place back in 2002, but nobody had realised it until now. It happened in an experiment at the CERN particle physics lab, when both...
  • A Stunning Demonstration of Why Good Science Needs Good Math

    Everyone is scientific circles is abuzz with the big news: there's proof that dark matter exists! The paper from the scientists who made the discovered is here; and a Sean Carroll (no relation) has a very good explanation on his blog, Cosmic Variance. This discovery happens to work as a great example of just why good science needs good math. As I always say, one of the ways to recognize a crackpot theory in physics is by the lack of math. For an example, you can look at the electric universe folks. They have a theory, and they make predictions:...

    JOKES about Jews and the Holocaust have become increasingly common at the Edinburgh Fringe as comedians tackle one of the last taboos. Some think that controversy over Israeli attacks on Lebanon have made Jewish history and beliefs worthy topics for stand-up routines. But one comedian has apologised after his outburst offended Jewish comedians and audience members. Steve Hughes, an Australian stand-up, told The Times that he regretted describing Richard Perle, an advisor to President George Bush, as “that f***ing Jew Richard Perle”. The comment, in his show The Storm, offended audience members including Jamie Glassman, a Jewish comedy writer. Glassman...

    Homeland Security: The war in Lebanon is an object lesson in border protection. Hezbollah secretly beefed up its forces there as Israel lowered its northern guard. Then Hezbollah attacked. We should take note. Lest Americans think this is "Israel's war," it's worth repeating that it was Hezbollah that bombed the U.S. Embassy and Marine barracks in Lebanon, killing some 250 Americans. Hezbollah also kidnapped Americans Terry Anderson and Beirut CIA Station Chief William Buckley. Buckley died in captivity with nine others. Some of the masterminds are still at large. --snip-- So now we have a Shiite enemy living among us,...
