In the beginning in the universe, there was nothing, no space, no matter, no light, no time and no sound. Then there was a sudden explosion of energy which we now call the Big Bang. But there was no BANG as there was no sound and no matter thrown out, as matter had not been formed yet. At 10-43 seconds, there was only a single point called a singularity that was very dense and contained a large amount of energy which was at an extremely high temperature. …show more content…
There you could never have enough energy to reach the speed of light. In 1905, Einstein, using his special theory of relativity showed that mass is actually just another form of energy and that in fact, they are equivalent. Equation E=mc2, (E=the energy released by an object in joules, m= the change in mass of an object in kg, c= the speed of light which is 3x108m.s-1.
Outline the discovery of the expansion of the Universe by Hubble, & its earlier prediction by Friedmann
Friedmann proved mathematically that the universe is expanding. However, he made some assumptions in order to prove it. Hubble showed that the Universe is expanding by showing that almost all the galaxies are red shifted, meaning that they are moving away from us.
Describe the probable origins of the Universe including the transformation of radiation into matter which follow the Big Bang
The Universe started with a Big Bang. At the beginning of the Big bang, there was only radiation. However over time ranging from 300 seconds to 1 million years, the particles combined to form atoms
