Albert Einsteins Theory of Relativity
He propeses that mass warps time and space, therefore large masses can bend light. -
Hubble's and Hooker's telescope
This telescope was the first major telescope to observe space in great detail. It was able to mesaure the distance and velocity of galaxies. Crucial in developement of the theory. -
Alexander Freidman Solves Einstein's Theory
He found that einstein only made sence if the universe was moving, not static as einstein had thought. -
Hubble's Law
Named after Edwin Hubble, which describes the galaxies as moving away proportional to the distance away they are. Further adds to the idea that the universe atrted in one spot. -
Georges Lemaitre's Theory
A belgium astronomer had an idea that at some point all pices of matter were concentrated in one atom a sort of cosmic egg. Eventually blowing up starting the universe. -
George Gamow's Paper
With his student Ralph Alpher they published "The Orgin of the chemical elements" in which they measured levels of hydrogen and helium in the universe largely explained by reactions that occured in the big bang. -
Fred Hoyle's Opposition
He disagreed with the "Big Bang Theory" which he named it. he believed the universe is expanding, but thought the universe was eternal. -
Bell Labs Radoation
A radio tower was recieving excess noise seeming to come from radiation. They decided the noise was our universe exploding. -
Brookhaven Lab
Made a device designed to recreate something that would have been there for a short period of time during the big bang. -
2Micron All Sky Survey
An infrared ballon spectrometer was used for three flights. To increase its sensitivity it was cooled ot one degree above absolute zero using helium. The observatiopns provide the most widely accepted suppport for the big bang theory until the launch of the cobe satalite. -
Hubble Approved
Congress approves the funding for the hubble telescope, allowing construction to start. -
COBE Satalite Launched
This satalite was launched to investigate the comic microwave backround radiation and provide measurements to help our understanding of the cosmos. -
The Expansion Is Accelerating
Two independent projects, the Supernova Cosmology Project and the High-Z Supernova Search Team, both measured the speed of the expansion using a far away super nova. They found that the expansion was accelerating -
Hubble Launched
The hubble telescope is finally launched after decades of imagining and construction. It is able to observe the galaxy in great detail. -
Universe Age is Discovered
WMAP scientists discover the universe is 13.7 billion years old.
