Gamma-ray astronomy has become a rich field of research and matured significantly since the launch of NASA's Compton Gamma Ray Observatory in April 1991. Studies of the diffuse gamma-ray emission of the Galaxy
Gamma rays are a form of electromagnetic radiation. They can be used to treat cancer, and gamma-ray bursts are studied by astronomers.
What are the harmful effects of gamma rays?What Are Gamma Rays:Gamma rays are high energy light rays. They come from nuclear reactions here on Earth or through cosmic interactions in space. Gamma rays can be incredibly damaging to humans due to the high energy contained in their waves....
Gamma Rays Gamma rays, or γ-rays, represent the most dangerous result of radioactivity to humans. They are massless because they are not particles at all. "Rays" is actually short for the general term electromagnetic radiation (EM radiation), which travels at the speed of light (denoted c,...
What speed do gamma rays travel at?Speed of Gamma Rays:Gamma rays are electromagnetic waves and are part of the electromagnetic spectrum. They occupy a position near one extreme of the spectrum and have very short wavelengths (in the picometer or smaller range) and very high frequencies (in ...
It absorbs and, in many cases, emits electromagnetic radiation in the form of gamma rays, visible light, infrared, and more. It can generate magnetic fields of various sorts and strengths. Matter has mass, creating the force of gravity, the effects of which can be readily observed. All ...

In humans, the propor- tion of mutations induced by long interspersed elements represents about 0.17% (Kidwell and Lish, 2002). This proportion is surprisingly low given the high abundance of these sequences in human genome (45%) and reveals that the amount of TEs is not related to the ...
In the 1960s,according to the American Physical Society, physicists Robert Pound and Glen Rebka shot gamma-rays first down, then up the side of a tower at Harvard University. Pound and Rebka found that the gamma-rays slightly changed frequency due to distortions caused by gravity. ...
As individuals, though, we rarely have the time or skills to justify our own beliefs. So what do we really mean when we say we know something? Hardwig posed a dilemma: Either much of our knowledge can be held only by a collective, not an individual, or individuals can “know” things...
