For more than a century, physicists have hunted for superconductivity in warmer materials.... In 1986, researchers uncovered ceramics that were superconductive at temperatures as high as 30 degrees above absolute zero, or minus 406 degrees Fahrenheit (minus 243 degrees Celsius). Later, in the 1990s, researchers first looked in earnest at very high pressures, to see if they might reveal new kinds of superconductors. The next big breakthrough came in 2001, when researchers showed that magnesium diboride (MgB2) was superconductive at 39 degrees above absolute zero, or minus 389 F (minus 234 C). Since then, the hunt for warm superconductors has...

Physicists who have been roaming the “landscape” of string theory—the space of zillions and zillions of mathematical solutions of the theory, where each solution provides the kinds of equations physicists need to describe reality—have stumbled upon a subset of such equations that have the same set of matter particles as exists in our universe. But this is no small subset: there are at least a quadrillion such solutions, making it the largest such set ever found in string theory.

To investigate Faraday waves, the team confined BECs to a linear one-dimensional waveguide, resulting in a cigar-shaped BEC. The researchers then shook the BECs using a weak, slowly oscillating magnetic field to modulate the strength of interactions between atoms in the 1D waveguide. The Faraday pattern emerged when the frequency of modulation was tuned near a collective mode resonance. But the team also noticed something unexpected: When the modulation was strong and the frequency was far below a Faraday resonance, the BEC broke into "grains" of varying size. Rice research scientist Jason Nguyen, lead co-author of the study, found the...

Atheism Is Inconsistent with the Scientific Method, Prizewinning Physicist Says In conversation, the 2019 Templeton Prize winner does not pull punches on the limits of science, the value of humility and the irrationality of nonbeliefLee Billings Marcelo Gleiser, a 60-year-old Brazil-born theoretical physicist at Dartmouth College and prolific science popularizer, has won this year’s Templeton Prize. Valued at just under $1.5 million, the award from the John Templeton Foundation annually recognizes an individual “who has made an exceptional contribution to affirming life’s spiritual dimension.” Its past recipients include scientific luminaries such as Sir Martin Rees and Freeman Dyson, as well...

Researchers there have developed a way to levitate and propel objects using only light, by adding specific nanoscale patterning to their surface. Scientists have the ability to move and manipulate tiny objects with the use of ‘optical tweezers.’ The tweezers move objects via the radiative pressure from a sharply focused beam of laser light. However, this impressive tool can only move small very small objects a very limited distance. The trick is to create very specific patterns on the object's surface. These nanoscale patterns interact with the light so that the object keeps ‘righting’ itself if disturbed so that it...

California scientists think they’ve found a way to make objects levitate using concentrated light — a theory that could even propel spacecraft farther than they’ve ever traveled before, according to a report. Researchers at the California Institute of Technology believe that by covering the surfaces of objects with microscopic nanoscale patterns specially designed to interact with beams of light, they could be propelled without fuel — and potentially by light sources millions of miles away, according to Phys.org.The findings, first detailed in the online science journal Nature Photonics, already have scientists salivating over the potentially out-of-this-world applications. One could be the...

Spacecraft already navigate our solar system using gravity wells as slingshots. The same basic principles operate in the intense gravity wells around black holes, which bend not only the paths of solid objects, but light itself. If a photon, or a light particle, enters a particular region in the vicinity of a black hole, it will do one partial circuit around the black hole and get flung back in exactly the same direction. Physicists call those regions "gravitational mirrors" and the photons they fling back "boomerang photons." Boomerang photons already move at the speed of light, so they don't pick...

At temperatures of 120 kelvin, or -240 degrees Fahrenheit, they saw clear signs that heat can travel through graphite in a wavelike motion. Points that were originally warm are left instantly cold, as the heat moves across the material at close to the speed of sound. The behavior resembles the wavelike way in which sound travels through air, so scientists have dubbed this exotic mode of heat transport "second sound."

Albert Einstein was born in Germany on March 14, 1879. He began teaching himself calculus at age 14. With a doctorate from the University of Zurich, Einstein wrote papers on electromagnetic energy, relativity, and statistical mechanics. Einstein predicted a ray of light from a distant star would appear to bend as it passed near the sun. When an eclipse confirmed this, the London Times ran the headline, Nov. 7, 1919, “Revolution in science – New theory of the Universe – Newtonian ideas overthrown.” In 1921, Albert Einstein won the Nobel Prize in physics. Describing the theory of relativity, Albert Einstein...

Researchers from the Moscow Institute of Physics and Technology teamed up with colleagues from the U.S. and Switzerland and returned the state of a quantum computer a fraction of a second into the past. "This is one in a series of papers on the possibility of violating the second law of thermodynamics. That law is closely related to the notion of the arrow of time that posits the one-way direction of time from the past to the future,"

FULL TITLE: QUANTUM TIME Scientists have built world’s first ‘time machine’ in experiment which defies the laws of physics ============================================================ Lead researcher Dr Gordey Lesovik said by putting scattered electrons back into their original shape they had effectively created a state which went against the 'direction of time' ============================================================ SCIENTISTS have built the world’s first time machine — sort of. Working with electrons in the bizarre realm of quantum mechanics, they first created the equivalent of a break for a game of pool. The “balls” scattered and, according to the laws of physics, should have appeared to split in a...

There’s a crisis brewing in the cosmos. Measurements over the past few years of the distances and velocities of faraway galaxies don’t agree with the increasingly controversial “standard model” of the cosmos that has prevailed for the past two decades. Astronomers think that a 9 percent discrepancy in the value of a long-sought number called the Hubble Constant, which describes how fast the universe is expanding, might be revealing something new and astounding about the universe. The cosmos has been expanding for 13.8 billion years and its present rate of expansion, known as the Hubble constant, gives the time elapsed...

Scientists have finally been able to accurately calculate the weight of the Milky Way, overcoming the difficult hurdle of measuring dark matter, the European Space Agency (ESA) announced Thursday. After years of struggling to estimate the size of our galaxy, astronomers with NASA and the ESA used data from the Hubble Space Telescope and the ESA’s Gaia mission to determine the Milky Way weighs about 1.5 trillion solar masses within a radius of 129,000 light years from the center. Because dark matter makes up about 90 percent of the galaxy, estimates of the Milky Way’s weight have differed widely in...

February 22, 2019 |   Salvatore Cezar Pais is a US Navy researcher. Salvatore has three amazing patents that would be incredible breakthroughs in physics if they are true. The least extreme is a patent for Piezoelectricity-Induced Room Temperature Superconductor. The other two patents are gravity wave generator and inertial mass reduction.If these could be realized as technologies then we are talking Star Trek level spaceships. The gravitational wave generator could be used for propellentless propulsion to near the speed of light. Being able to reduce inertia would also mean capabilities which currently seem beyond known physics.The more likely situation...

Located in the constellation of Hercules, about 230 million light-years away, NGC 6052 is a pair of colliding galaxies. They were first discovered in 1784 by William Herschel and were originally classified as a single irregular galaxy because of their odd shape. However, we now know that NGC 6052 actually consists of two galaxies that are in the process of colliding. This particular image of NGC 6052 was taken using the Wide Field Camera 3 on the NASA/ESA Hubble Space Telescope. A long time ago gravity drew the two galaxies together into the chaotic state we now observe. Stars from...

Dozens of manuscripts belonging to Albert Einstein, many of them unseen in public before, have been unveiled by the Hebrew University of Jerusalem. More than 110 new documents are now on display at the university, marking the 140th anniversary of Einstein's birth. It was donated by the Crown-Goodman Family Foundation and purchased from a private collector in North Carolina. The manuscripts contain an appendix to Einstein's article on Unified Theory ... The collection includes scientific work by the Nobel Prize winner that has never been published or researched.

nitiated by physicists at the University of California, Irvine, the five-year FASER project is funded by grants of $1 million each from the Heising-Simons Foundation and the Simons Foundation – with additional support from CERN, the European Organization for Nuclear Research. ASER's focus is to find light, extremely weakly interacting particles that have so far eluded scientists, even in the high-energy experiments conducted at the CERN-operated LHC, the largest particle accelerator in the world. Feng, a theoretical physicist, will be joined by CERN collaborators as well as other scientists from research institutions in Europe, China, Japan and the United States....

Qubits, the units used to encode information in quantum computing, are not all created equal. Some researchers believe that topological qubits, which are tougher and less susceptible to environmental noise than other kinds, may be the best medium for pushing quantum computing forward. Quantum physics deals with how fundamental particles interact and sometimes come together to form new particles called quasiparticles. Quasiparticles appear in fancy theoretical models, but observing and measuring them experimentally has been a challenge. With the creation of a new device that allows researchers to probe interference of quasiparticles, we may be one giant leap closer. The...

Co-founder of string field theory and physicist Michio Kaku made waves last year — or at least seemed to — when it was reported that he’d proven the existence of God. The Geophilosophical Association of Anthropological and Cultural Studies quoted Kaku as saying, "I have concluded that we are in a world made by rules created by an intelligence. To me, it is clear that we exist in a plan which is governed by rules that were created, shaped by a universal intelligence and not by chance." Reacting to that public comment, Kaku said: "That’s one of the drawbacks...

An emerging consensus suggests the crash can explain distant gamma-ray bursts GREAT ESCAPE A bright jet of fast-moving particles fled the scene after two neutron stars collided, spewing material and potentially forming a black hole (shown in this artist’s illustration). When a pair of ultradense cores of dead stars smashed into one another, the collision shot a bright jet of charged subatomic particles through space. Astronomers thought no such jet had made it out of the wreckage of the neutron star crash, first detected in August 2017. But new observations of the crash site using a network of radio telescopes...
