Big Bang is something like a “Bang” which means to explode which is true. Big Bang concept was first given by Fred Hoyle English Astronomer. He gave the concept of “steady State” model to represent the Big Bang model. Big Bang can be measured with the structure of the universe and some observations. Vesto Splipher in 1912 from the Doppler Shift (Note: Doppler Shift is given by Austrian Physicist Christian Doppler, in his effect he said universe is expanding as galaxies are receding from us by his two shifts red shift and blue shift. In red shift, an observer looking at galaxies are moving away from us and has longer wavelength, where as in blue shift an observer looking at galaxies are reaching towards this and hence has shorter wavelength. He gave the Doppler Effect concept in 1842) noticed a case of spiral nebulas (which is the obsolete from of spiral galaxy). He also notices that spiral nebulas are receding from us.
