it made plants survive and it gave us sunburns, there for they thought it gave off energy and it DOES
Early scientists thought that the sun produced its energy through gravitational contraction, but this theory was later disproven by the discovery of nuclear fusion. Nuclear fusion, a process where hydrogen atoms combine to form helium with the release of energy, is now known to be the main source of the sun's energy.
Later scientists, particularly in the 20th century, discovered that the Sun produces energy through nuclear fusion reactions in its core. This process involves the fusion of hydrogen atoms to form helium, releasing massive amounts of energy in the form of light and heat.
Scientists centuries ago believed that a nuclear reaction which was very large would be capable of producing the energy of the sun, they thought this because when they experimented with nuclear reactions and measuring the energy produced the reaction of coal not burning long without being consumed.
Scientists can learn a large amount of information about light from rainbows.

I suppose that you think to physicists.
I think it is ability to make tools
no it is not. i think...
scientists are concerned about conserving energy because one day our non renewable energy might get extinct and they need to think of another energy that might work.
Fossil fuels, our primary source of power, will someday run out. As a result, we need to develop other, possibly safer alternatives.
false
As far was we know the development requires water in its liquid for to be present and a source of energy to supply/drive chemical reactions. We know that deep down Europa has a liquid layer (of water) and the geysers of this water into space proves that there is energy in Europa's core.
hydrogen
first of all I think a battery is a main source of energy :P
TRY READING THE BOOK AND PAYING ATTENTION IN CLASS FOR ONCE! I THINK THAT MAY HELP, just a little bit!
