where gamma-rays themselves are a high-energy form of light, can travel faster-than-light? That's what Dr. Jeff Landrum wants to know, asking: What gives? Is it really possible for gamma-rays to ...

If we could produce coherent gamma rays just as an ordinary laser produces coherent rays of visual light, the technology could unlock interstellar travel—as well as blow missiles out of the sky ...

No, the laws of physics aren't being violated: It's still true that nothing can travel faster than light ... light in the universe, called gamma-ray bursts. Related: 8 Ways You Can See Einstein ...

During the time it takes for its wave to go through one cycle, a gamma-ray wave traveling at the speed of light will travel only the width of a proton, a tiny particle found within the nucleus of ...

Each of these cosmic events adds to the tapestry of gamma rays that travel through space. The journey of gamma rays to Earth is a remarkable one. Despite their high energy, these rays can be ...

The Franco-Chinese space mission SVOM has just entered a new phase: after nine months of testing, the satellite is officially ready to operate at full capacity. Its main objective? Observing the ...

The greater the cosmic-ray energy, the greater its interaction cross-section, meaning it is more likely to interact with CMB photons. The constant interactions between cosmic rays and CMB photons ...

What does radiation do? Gamma rays are the highest energy rays in the electromagnetic spectrum. They are so energetic that they can travel great distances through the air or other material ...

Thunderstorms are known to generate gamma rays, the highest energy radiation on Earth. But pinning the burst to a specific bolt is new.

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film ...
