Transcript of The "Universe"

The "Universe"
Scientific Revolution
The scientific revolution is the period after the black plague ( bubonic plague ), It is when Copernicus said that the Earth was in the center not the sun and made the heliocentric model of the solar system. Galileo was supporting Copernicus's theory with the lots of research and the help of his simple telescope which he renovated.
astrophysics contribution
Astrophysics is a branch of astronomy that deals with the physical nature of celestial bodies. It applies the theories and laws of physics to the interpretation of astronomical observations.
Astrophysicists such as Ptolemy, Copernicus and Galileo have contributed to how the world looks and where each of the planet is. Ptolemy thought that the Earth was in the center and made the geocentric model of our solar system. Later after the black plague came the scientific revolution where Copernicus made the heliocentric model of our solar system in which the earth is not in the center and the sun is (this is also over modern world model) and Galileo supported Copernicus's theory and the heliocentric model which he had made to show us our solar system.
Edwin Hubble is a famous astrophysicist who had discovered that the universe goes beyond our galaxy milky way he had given proof for this theory with the worlds largest telescope which is hooker telescope. He observed nebulae for some time and then realized that there is universe even beyond the milky way. One more is that the Redshift increases with distance. He also discovered the asteroid 1373 Cincinnati and He gave efficient proof for the big bang and also wrote two books which are:
The Observational Approach to Cosmology
The Realm of the Nebulae
Black Holes
A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. The strong gravity occurs because matter has been pressed into a tiny space. This compression can take place at the end of a star's life. Some black holes are a result of dying stars.
Because no light can escape, black holes are invisible. However, space telescopes with special instruments can help find black holes. They can observe the behavior of material and stars that are very close to black holes.
Astrophysics has contributed a lot to the ideas and theories of the universe. Few of them were included during the scientific revolution period. and a few of them before that. This helps us to give us a very detailed idea on the universe of how it was formed and so on. Few famous astrophysicists are:
Einstein
Galileo
Copernicus
Ptolemy
Hubble
ETC.
Everyone knows Einstein for his most famous equation which is E=MC2. But this is not his only contribution he has done many other stuff, one famous contribution to the field of astrophysics is that of the space time. He also spoke about the general relativity General relativity is also about space and time and also Sir Isaac newton's universal law of gravity. One more famous contribution to astrophysics is about anti gravity.
Sequential order of Events
The Big Bang
