So,now the question is how we came to know about it..?
Actually,in 1921 a Physicist name Edwin Hubble observed that the lights from distant galaxies are stretched. so from where he assumed that the Universe is expanding and then we started to think that there might be a start from where it all began.
Just after the second of Big bang every Fundamental forces of nature come into play and those are became most important phenomena in Universe like the Gravitational force which for which we can stand on the earth and moon doesn't fall on earth,the Electromagnetic force which lights up the city and for which we can communicate finally the two nuclear force which holds an atom for which the human body remain stable and gives power to sun.
