INSIDE SCIENCE

 In 1960, Freeman Dyson, a British American Mathematical Physics and Astrophysics, mentioned a Dyson Sphere in a science paper, search for the artificial stellar source of infrared radiation. According to him, if there is an advanced Civilization in our Galaxy, how will we know about it?  So we can see them from their main star . There will have a spherical structure that is around their star .  All the energy from that star would be used by that civilization.  Freeman Dyson named it a Dyson sphere.  It will be a giant structure that will be built around that star. This will accumulate a large amount of energy of that star.  Image source-google | Image by- Kevin Gill In that case the star will in infrared. The need for energy on our planet is increasing day by day.  For which we're meeting the demand for energy from chemical fuels, electricity and today through nuclear fusion reactors. But all this energy resources are limited. This will surely end on...

Until five centuries ago, it was believed that there is only on earth in the entire universe and that this is the centre of the entire universe. All the stars in the night sky revolve around the earth. But in the year of 1558, Giordano Bruno was born. Giordano Bruno appeared in 1600 AD and stated that the earth is not the centre of the universe but a small part of it. The light visible in the night sky is actually the stars like the sun, which have planets and moons of the planets and have life on them just like on our earth. The universe is infinite in every direction; it has no centre and no boundaries. Earth like planets is innumerable in the universe. But the clergy refused to believe him. They were not at all prepared to believe that there could be life beyond the earth. Giordano Bruno was prosecuted and forced to change his mind. But he did not change his mind at all. He had realized the depth of this universe. So there was no fear in him. He was tried and given very severe puni...
