One of the biggest unsolved problems in physics has to do with combining quantum mechanics and general relativity – two theories that are equally successful. And the latest attempt to close the bridge brings into the equation the explosion that started everything: the Big Bang. In a recent paper in Physical Review Letters, physicists at … Read more
researchers may have found the first direct evidence of ancient black holes, which could revolutionize our understanding of dark matter. A gravitational wave, captured by LIGO in November 2025proposed a revolutionary hypothesis: the collision that produced the signal may not have involved ordinary black holes in stars, but rather black holes formed in the early … Read more
When our powerful infrared telescopes allowed astronomers to look further into the future, they made some amazing discoveries. One of them involves supermassive black holes (SMBH), the physics-defying behemoths at the center of massive galaxies such as the Milky Way. In fact, the SMBH grew much faster in the jewelry world than it does in … Read more
A photon from a star billions of light-years away takes no time to reach a telescope. It’s not too little time. There is nothing. That result is not a measured or poetic way of speaking. It comes directly from the mathematics of special relativity, and it points to another strange thing about the nature of … Read more
Elliot McGucken These photos of 70-foot-tall cones of light shining in the California desert may look pretty, but they have a surface and actually represent some interesting ideas about the evolution of space-time. Dr. Elliot McGucken is a nationally recognized photographer and Ph.D. a physicist. He likes to combine his two passions, which he believes … Read more
When Ryland Grace arrived at Tau Ceti in Ahe Mary projectalmost four years have passed for his human body and weak mind. But, due to the effects of time dilation, about 12 to 14 years have passed on Earth. And that’s just the beginning of the story. At the end of the Ahe Mary projectdecades … Read more
Astronomers have long argued that dark matter is the invisible scaffolding that holds galaxies together. Without its immense gravitational pull, the galaxies’ rotating necks would force them to fly sideways. But now, scientists have found a series of galaxies that do not seem to have their dark matter completely. The latest in this string, known … Read more
Six Timepix chips developed at CERN will measure the radiation environment in the spacecraft that will orbit the Moon during NASA’s Artemis II mission. At 00:35 CEST today, the mission of Artemis II successfully began, marking the first manned trip to the Moon since 1972. During their ten-day journey in the Orion spacecraft, the four … Read more
Scientists have struggled for years to explain the mysterious mechanism inside tokamaks, donut-shaped machines designed to one day generate electricity by fusing atoms together. Inside these devices, superheated plasma is held in place by gravity. Some of those particles eventually escape from the back and head towards the smoke chamber, called the divertor. When the … Read more
By mid-2025, the group of physicists to Massachusetts Institute of Technology achieved something that had eluded researchers for nearly a century: the direct visualization of an obscure “second sound.” This is a rare regime there temperature it is no longer different but moves like the wavehumming like sound in a quantum liquid. The findings, published … Read more
