According to one theory, muons may be the reason. These subatomic particles, about 200 times heavier than electrons, are produced by gamma rays. Large megafauna even half a mile (0.8 km) underwater would have been especially subject to their lethal effects. Based on iron-60 traces in seafloo...
it is called a nuclear stress test, myocardial perfusion scan, or SPECT scan. SPECT stands for single-photon emission computed tomography—“single-photon,” because the radioisotopes emit only a single type of radiation (gamma rays). A special camera ...

(In order of increasing frequency, the electromagnetic spectrum is:Radio,Microwave,Infrared,Visible,Ultraviolet,X-rays,Gamma rays.) Example #2 Question:Stalactites and stalagmites– which ones grow from the top of the cave and which ones grow from the ground? Answer: Stalactites grow from theto...
Ultraviolet Rays 10-400nm Wavelength range invisible to the human eye Blue light refers to visible light (400-800nm) with short wavelengths (around 400-500nm). The reason it has recently been the subject of attention is that there are many LCD products with LED backlights that have a high...
The resulting debris and dust would also block out the sun's rays, causing a drop in global temperatures and disrupting the Earth's ecosystem. However, the likelihood of a large asteroid impact is relatively low, and scientists are continuously monitoring and tracking any potential threats....

Apopular breed of the 1930s and 1940s, Scotties were bred as watchdogs and farm helpers, so they are used to being independent and aloof. They carry themselves with confidence and respond well to different vocal cues. You may also like:Dog breeds gaining the most popularity ...
, visible only in gamma rays and weighing the equivalent of millions of Suns, are called the Fermi Bubbles. The Fermi Bubbles and the Magellanic Stream were thought to be separate and unrelated to each other, but now it appears that the same powerful flash from our gala...
