Galactic Redshifts
Vesto Slipher and Carl Wirtz spy galactic redshifts in the sky -
Theory of Relativity

Alexander Friedman
Alexander Friedman was a Russian Mathmatition and was the first to predict the expansion of the universe. -
Expanding universe model
Belgian Catholic Priest Georges Lemaitre proposes an expanding model for the universe. -
Hubble Demonstrates Expanding Universe
Edwin Hubble demonstrates that the universe is indeed expanding. -
Radio Waves from Milky Way
Bell Labs researcher Karl Jansky discovers radio waves coming from the Milky Way. -
New info on Radio Waves
We now know that cosmic-ray electrons spiraling about interstellar magnetic field lines produce the bulk of the so-called radio continuum emission from the Milky Way. -
Fritz Zwicky
Fritz Zwicky was a Swiss engineer who was the first to hypothesize about Dark Matter. -
Steady State theory
According to the Steady State theory; Fred Hoyle, Thomas Gold, and Hermann Bondi state that new matter is created as the universe expands. -
Holmdel Antenna Built
The Holmdel antenna is built to support NASA's Project Echo, and later Telstar. -
Cosmic Background Radiation Theory
Princeton astrophysicist Robert Dicke theorizes that cosmic background radiation is emanating from the universe due to a "Big Bang." -
"Hum" coming through the Antenna
Bell Labs researchers Arno Penzias and Robert Wilson find a low, steady "hum" coming through the Holmdel Horn antenna. -
Hum noise comes from outside galaxy
Penzias and Wilson conclude that the noise is coming from outside the galaxy, providing solid evidence for the Big Bang. -
Hubble Telescope is launched
The Hubble telescope was launched on April 24, 1990. Since the telescope is outside the Earth's atmosphere, it gets rid of the problem of distorted pictures form the atmosphere. This allows it to see deeper into space than any telescope before it. -
Dark Energy
As scientist grasped a better understanding of the Big Bang Theory and the creation of the universe, their observations changed with the discovery of dark energy. This is energy they can not understand that instead of pulling galaxies together, it is pushing them appart and accelerating the separation instead of slowing it. -
