Quasars are large supermassive black holes at the centre of a galaxy that is so active that it tends to outshine the stars in the galaxy. Quasars tend to have accretion discs of gas and dust; when material from the disc falls into the Quasar, it is ejected as electromagnetic radiation. ...
The radiation of components in a fusion reactor is not much enough for the materials to be reused or recycled within centuries. Can fusion reactors explode? Can fusion cause a nuclear accident? No, because fusion energy production is not based on a chain reaction, as is fission. Plasma must ...
This is also the speed that any form of pure radiation, such as gravitational radiation, must travel at, and also the speed, under the laws of relativity, that any massless particle must travel at. ...We can never reach the speed of light. Or, more accurately, we can never reach the ...
I have been given hormonal medication to “slow the rate of tumour growth”, as further chemotherapy or radiation is considered not suitable for me. I have been exploring other avenues e.g. anti-cancer diets and use of sound frequency to “kill cancer cells in the body”. But it is so...
“Black holes are predicted to evaporate by making radiation — what’s called the Hawking Process,” he says, “but only until they get down to an equilibrium with the temperature of the cosmic microwave background.” This process, says Smolin, has to do with the properties of the horizon...
When that high-energy neutrino collides with the nucleus of an atom in the ice, it can produce charged subatomic particles also traveling faster than light. These speedy particles emit a flash of light known as Cherenkov radiation, making the neutrino indirectly detectable. And in 2016, IceCube ...
'Killer electrons' play pinball with space weather around Earth"Killer electrons" stashed in radiation belts around Earth could be dislodged by lightning to create a game of "cosmic pinball" that influences space weather around our planet.Space These Are The Most Beautiful Women In The World5min...
While there isn't an ongoing search for life currently on the surface of Mars, the Martian subsurface may be where the action is. "I'm one who thinks it might be closer to the surface than we think," Cabrol said. "We might discover that in places, life is protected from radiation. ...
‘happy hormone’ as it influences mood….. But too much sun exposure not only increases skin cancer and cataract risk but also literally overheats the brain and the radiation from the sun enters and ages the brain. In the summer those spending around 2 hours outdoors have the best ...
These materials have very low visible-light transmittance levels, but they transmit an unacceptably high level of near-infrared radiation that can burn your retinas. The fact that the sun appears dim, or that you feel no discomfort when looking at the sun through these types of filters, is ...
