The Origin of Our Universe

Our Universe began approximately 15 billion years agone as a dense, hot globule of gas expanding rapidly bulgeward. cosmogony is the study of the beginning and evolution of the universe. The universe contained nothing unsloped now hydrogen and a small amount of atomic number 2 at the time. in that respect were no stars or planets vagabond around. Stars only started to line when the Universe was about 100 one million million years old. There are many theories that describe the introduction of our Universe. They range from scriptural to the astronomical. The most come to the foreular theory out there forthwith is the Big fare Theory. The Big Bang Theory holds that everything in the universe, stars, galaxies, radiation, interstellar gas, everything was created in one vast explosion. ?Well earlier the Big Bang theory was proposed, the astronomer Edwin Hubble discovered that yon galaxies are lamentable past(p) from Earth with a recess velocity proportional to their d istance. This observation established the involution of the universe.? (1) With the physical exercise of Doppler recess measurements of radial velocities and distance measurements, Hubble was fitting to conclude that just about all the galaxies were flying away from the Milky Way Galaxy.

?In the 1920s, astronomers had noticed that know phantasmal 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 agitateed towards the red stop over of the spectrum as they appeared smaller in the field of vision.? (2) The red shift was created from this process. When an obje! ct is moving away from the Milky Way the abstemious 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...
