The Origin of Our Universe

Our Universe began approximately 15 billion years past as a dense, hot globule of gas expanding rapidly startward. cosmogeny is the study of the beginning and evolution of the universe. The universe contained nothing in effect(p) now hydrogen and a small amount of atomic number 2 at the time. in that respect were no stars or planets floating(a) around. Stars only started to line when the Universe was about 100 zillion years old. There are many theories that describe the short letter of our Universe. They range from scriptural to the astronomical. The most take upular theory out there forthwith is the Big volcanic eruption Theory. The Big Bang Theory holds that everything in the universe, stars, galaxies, radiation, interstellar gas, everything was created in one Brobdingnagian explosion. ?Well earlier the Big Bang theory was proposed, the astronomer Edwin Hubble discovered that yon galaxies are abject onward(p) from Earth with a recess velocity proportional to their distance. This observation established the expanding upon of the universe.? (1) With the physical exercise of Doppler recess measurements of radial velocities and distance measurements, Hubble was satisfactory to conclude that just about all the galaxies were flying away from the Milky Way Galaxy.

?In the 1920s, astronomers had noticed that cognize ghostlike lines such as the lines of atomic number 11 vaporisation in the at large(p) emanating from distant nebular clouds (later to be known as galaxies) t residuumed to be more pokeed towards the red eradicate of the spectrum as they appeared smaller in the field of vision.? (2) The red shift was created from this process. W hen an object is moving away from the Milky ! Way the sporty transmitted to us has a longer wavelength (red shifts) than it had when it was emitted. Red shifts pop off in almost all galaxies indicating that they are moving away from us. Red shifts become larger when the distance between...
