In order to grasp and control a body of knowledge we need to build blocks of knowledge. Adding to our trip around the universe we need to attain an understanding of how light exists and operates. Light is made of electromagnetic waves and it travels through space at 186,000 miles per minute. How does this happen? What drives this force to travel billions of light years?
ELECTRICITY:
Electricity is the flow of electrical power or charge. It is a secondary energy source which means that we get it from conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural source, which are called primary source. Our electric energy comes in 4 types: static electricity, current electricity, hydro electricity and solar electricity.
Electricity in Space:
Extremely energetic light from space is a unexplained wonder. Scientists’ don’t know where the light comes from, exactly. And now astronomers have spotted this light called gamma rays, at higher energies than ever before. You can’t see gamma rays with our eyes. They are much more energetic than the light that we can see.
The hotspots ( gamma rays) hint that our galaxy, the Milky Way, has powerful particle accelerators. But these particle accelerators aren’t made by humans. Instead, they come from violent event in the cosmos. They might be exploding stars, for example.
Such violent events make electric and magnetic fields. Those can speed up protons and electrons. Those fast particle can then produce gamma rays with a lot of energy. That can happen when protons interact with other matter in space. (Emily Conover / Science News for Students)
A gamma ray is also known as gamma radiation, and is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest proton energy. (Wikipedia)
Electromagnetic field, a property of space caused by the motion of an electric charge.
