As far as we know, the universe is made up of fundamental particles like electrons and quarks. Everything we see in the universe, including ourselves, is the result of interactions between these particles. Fundamental forces mean interactions of elementary particles. Four fundamental forces have been identified. They are gravitational force, electromagnetic force, weak nuclear force…
Infrared radiation from a black body is analyzed and used to determine its temperature. The object is seen in the color of brass. Activity. First, the pressure is reduced by means of a vacuum pump. The temperature is then reduced with liquid nitrogen. The black body is then placed in front of the source. The…
Plasma with high brightness is a giant sphere held together by gravity. The Sun is the closest star to the Earth, and is the source of most of the Earth’s energy. The stars appear when other atmospheric phenomena are uninterrupted during the night when the sun is absent. Historically, some of the major stars in…

How did water come to earth? Certainly not after the earth came into being. Water is older than earth. The water we use contains the hydrogen produced by the Big Bang. And the explosion of oxygen stars in it. So there is more water available in space than we think. It only tells the most…
