Theory of Relativity
Albert Einstein discovered the theory of relativity which states that General relativity shows that objects continue to move in a straight line in space-time, but we see it moving as acceleration because of the curved nature of space-time. -
The Big Bang
The Big Bang was discovered -
Alexander Friedmann solutions
Alexander Friedmann provides solutions to the field equations used for many of the theories of the Big Bang but supporting only it. This helped in future working of the theory as well. -
Hubble's Law
Edwin Hubble (1889-1953) discovers that outer galaxies are moving away from the Milky Way at a rate that is propotional to the size of the galaxy. This discovery supports the theory that the universe expanded after being completely compacted. -
George Gamow
George Gamow finds theory that fits with Friedmanns solutions concluding that the universe expanded from a hot, dense state. -
"The Big Bang"
Fred Hoyle opposes the theory but uses the term the big bang and it sticks. Magazines held contests trying to find a better name but no conclusion was ever made. -
Fred Hoyle
Fred Hoyle rejects the theory of the big bang and suggests life has a cosmic, not extraterrestrial origin. He also stated that viruses could come from certain meteors. -
CMB Radiation discovery
Radioastronomers Arno Penzias and Robert Wilson discovered a 2.725kelvin Cosmic Microwave Background. This provides evidence of the big bang's heat imprint in the earth. -
Sloan Digital Sky Survey
Sloan digital sky survey is a telescope that maps certain areas of the sky. THis makes it easier for scientists to map and find new planets and stars. -
Hubble Telescope
Telescope carried into space on a shuttle mission and used to obtain information and photographs from space. hehe:)
