Scene 3

Scene 4

Scene 5

Scene 6

The Big Bang theory is the birth of the Universe. Before the big bang theory there wasn’t space and time, the Universe expanded from a point to the infinite space today. The Universe began when the mass of the Universe was compressed into super hot balls smaller than an atom. It happens with an explosion expansion, balloting the Universe outwards faster than the speed of light. After that, the Universe expands rapidly from a very hot and dense state. The age of the Universe is about 13.8 billion years old.

Scene 7

The universe cooled and matter formed as space expanded. The universe was filled with neutrons, protons, electrons, anti-electrons, photons, and neutrinos one second after the Big Bang. The light elements were created during the first three minutes of the universe, a process known as Big Bang nucleosynthesis.

Scene 8

A Belgian priest named Georges Lemaitre first suggested the big bang theory in the 1920’s when he theorized that the universe began from a single primordial atom. In the late 1920’s another Astronomer, Edwin Hubble, made a very interesting and important discovery. Hubble made observations that he interpreted as showing that distant stars and galaxies are receding from Earth in every direction. Hubble’s hypothesis of an expanding universe leads to certain deductions, one is that the universe was more condensed at a previous time. From this deduction came the suggestion that all the currently observed matter and energy in the universe were initially condensed in a very small and infinitely hot mass. A huge explosion known as the Big Bang then sent matter and energy expanding in all directions.

Scene 9

One scientist who contributed the theory “The Big Bang” was named Georges Lemaitre, he is known to be a  belgian  cosmologist and Catholic Priest. Arno Penzias and Robert Wilson had discovered the cosmic microwave background radiation, the first and still most important observational evidence in support of the Big Bang.

Scene 10

The red-shift of light- if the object is traveling towards us, the wavelength is shifted towards the blue end of the spectrum, if the object is traveling away from us, the wavelength is shifted towards the red end. Cosmic background microwave radiation is described to be and the last one is an abundance of elements. This is to be the cosmic microwave background, in Big Bang cosmology, is electromagnetic radiation which is a remnant from an early stage of the universe, also known as a “relic radiation”.  the abundance of elements- The abundance of the chemical elements is a measure of the occurrence of the chemical elements relative to all other elements in a given environment.

Scene 11

Edwin Hubble first discovered the expansion of the Universe according to the expansion of the Universe. He observed that the Galaxy of the universe is moving away from each other at high speed. The farther the galaxy is, the faster it is moving. Yes this evidence has been proven because the Theory has remained largely consistent with the observation and is widely accepted through the cosmology community.
