Activuty 3: Big Bang

Big Bang



The theory of Big Bang is an explication of the creation of the world.
In 12.000 and 15.000 millions of years approximate the matter of the Universe stood concentrated in a little zone and this matter exploded. The matter is driven with big energy in the different directions.

The clashes made the matter group and this matter was concentrated and formed the first stars and first galaxies. In three minutes, the temperature dropped below 1 billion degrees Celsius, and thanks to the temperature the protons and neutrons got together making the hydrogen and helium nuclei.

The Universe cooled to about 3.000 degrees. The Universe filled with clouds of hydrogen and helium gas after 300.000 years.

We can try to imagine the Big Bang as a balloon that inflates. The surface of the globe will be the space, and our sphere will be the force that began the expansion. We start blowing, and all at once the piece of amorphous and wrinkled rubber moves in and takes a spherical position. And it grows.

Albert Einstein

14th march 1879
Albert Einstein, his theory of special relativity, determined that the laws of physics are the same for all observers who do not accelerate, and demonstrated that the speed of light within the vacuum is the same regardless of the speed at which it travels An observer.
Isaac Newton
January 4, 1643
The theory elaborated by Isaac Newton affirms that this force of attraction, called gravity, is responsible for the fall of bodies on Earth and the large-scale movements observed in the Universe.
Nicholas Copernicus
February 19, 1473
Nicholas Copernicus was a polymath of the Renaissance era whose theory of the universe placed the Sun instead of the Earth at the center of the universe.
Edwin Hubble
20 November 1889
He also definitely demonstrated that the universe was expanding, and formulated what is now known as the Hubble Law to show that the other galaxies are moving away from the Milky Way at a speed directly proportional to their distance from it.
Carl Sagan
November 9, 1934
Carl Sagan was one of the most well-known scientists of the 1970s and 1980s. He studied extraterrestrial intelligence, advocated for nuclear disarmament and co-wrote and hosted 'Cosmos: A Personal Voyage
