Astrophysicists often talk about gravitational lensing, one of the most interesting aspects of light’s infamous particle-wave duality. This phenomenon shows in a predictable and measurable way how the small mass within each photon of light shooting out from a distant star actually bends the light in the gravitational pull of dense objects along its path. … Read more
The arrow of time moves forward. Eggs don’t break. Milk won’t spill. But now, new research has discovered a way to reverse this arrow in quantum systems, causing events to flip-flop as if time were flowing backwards. The finding is theoretical at this point, but could be tested experimentally, said Luis Pedro García-Pintos, a physicist … Read more
Black holes have long been associated with inconsistencies and limitations in known physics, particularly regarding how black holes interact with their environment. One such interaction involves tidal forces, the gravitational effects exerted by nearby objects, and is commonly used to investigate the internal structure of celestial bodies. For decades, scientists have relied on a quantity … Read more
Muon-catalyzed fusion is one of those strange concepts that holds enough promise to intrigue researchers, but stubbornly resists practical application. The central idea underlying this process is to replace the electrons in the hydrogen with heavier particles called muons, which draw the atomic nuclei so close together that nuclear fusion (a process that occurs at … Read more
Almost a century ago, famous astronomer Edwin Hubble determined that the universe was expanding at an accelerating rate. He discovered that the farther a galaxy is from Earth, the faster it appears to be moving away from us. It was an elegant observation that underpins much of today’s cosmology. But determining the exact relationship between … Read more
Sign up now and see the future Don’t miss innovations from the cutting edge of science and technology Almost a century ago, famous astronomer Edwin Hubble determined that the universe was expanding at an accelerating rate. He discovered that the farther a galaxy is from Earth, the faster it appears to be moving away from … Read more
Researchers have detected for the first time that voids in the sky are moving faster than people. speed of light And they broke the speed limit of the universe without breaking the theory of relativity. Recent studies have shown void acceleration. The researchers used recent advances in ultrafast electron microscopy to measure the voids of … Read more
