Science: Universe created in "Big Bang"


Astronomers now virtually all agree that the universe was created in the "Big Bang".  The universe was created about 13.7 billion years ago, and is expanding from that initial small, dense, and hot state. Evidence for the big bang theory is now overwhelming.

Below are just some of the many discoveries supporting the Big Bang. For more information also see NASA Origins Web Site

The expanding Universe:
In 1929 Astronomer Edwin Hubble, proved from his measurements on 40 galaxies that they were moving away from each other in the manner that Einstein had predicted.  Since then, more accurate measurements of the velocities of galaxies establish that such a cosmic expansion has been proceeding for the past about 14 billion years.

Einstein's Theory of General Relativity:
One of the first clues the universe came about in a big bang was the implication that the universe is expanding from Einstein's theory of general relativity. First published in 1915, it is now one of the most exhaustively tested principles in all of physics.

Existence of Cosmic Background Radiation:
It was predicted that if the Big Bang were correct, that the cooling from it would yield a faint cosmic background radiation. In 1965 Bell Laboratory physicists Arno Penzias and Robert Wilson unexpectedly discovered this background radiation of about 3º while measuring radio emissions from our galaxy. They later received the Nobel Prize for their discovery.

Exact Characteristics of the Cosmic Background Radiation:
Since the launch of NASA's COBE & WMAP satellites, much more data on the cosmic background radiation has confirmed not only it's existence, but also that the characteristics of it match the Big Bang model: NASA's data center for Cosmic Microwave Background research

1. Cooling of background radiation fits Big Bang.
2. Black Body Character of the Cosmic Background Radiation fits the Big Bang.
3. Nature of irregularities of Black Body radiation.

Space Time Theorem of General Relativity
The space time theorem of general relativity, formulated by Stephen Hawking and Roger Penrose in 1970, states categorically that the universe's cause (or Causer) must have brought it into existence from outside the universe's matter, energy, and the unfolding dimensions of space and time.

In an interview Hawking stated directly "time has a beginning".1
