1.Some galaxies appear to be moving away from us at speeds proportional to their distance. This is called "Hubble's Law," named after Edwin Hubble (1889-1953) who discovered this phenomenon in 1929. This observation supports the expansion of the universe and suggests that the universe was once compacted.

2.The initial, very hot state that followed the Big Bang should have left some remnant of its heat. In 1965, Radioastronomers Arno Penzias and Robert Wilson discovered a 2.725 degree Kelvin (-454.765 degree Fahrenheit, -270.425 degree Celsius) Cosmic Microwave Background radiation (CMB) which pervades the observable universe. This is thought to be the remnant which scientists were looking for. Penzias and Wilson shared in the 1978 Nobel Prize for Physics for their discovery.

3. The abundance of the "light elements" hydrogen and helium found in the observable universe (which would have been the first elements formed) is thought to support the Big Bang model of origins

1.Moon is coming closer to earth : Experiments need high energy like the expriment of god particle . as we know in higgs boson particle experiment the scientists are finding a particle smaller than electron or the energy that had made the universe as explained in Big Bang Theory. & in this experiment we saw a flash of particle just nearly for .0001 seconds. But this energy which is made & the energy used for conducting these expeiments are continuously affecting the atmospher e & breaking the force b/w earth & moon . We can imagine the intensity of energy as it is breAKING such a great bond of force.
