If you tune your TV between channels then some of the fizzing snow on the screen is apparently the radiation after glow from the big bang, roughly 13800000000 years ago. The universe has been expanding ever since and is now approx 30 billion light years across, to get an idea of size, if you could travel at a million miles a second it would take you about 6 billion years to cross the universe. |

The big bang theory came about first by noticing that the universe is expanding. We can see that it is expanding by examining the shift in the wavelengths of light coming from stars in other galaxies. When things are moving very quickly away from a one point of view, the light emitted from the origin is shifted towards the red spectrum. This is known as the "Doppler" effect. It is the same effect you get when you are standing near a train track, and hear a passing train blow its whistle... the pitch seems to drop as it goes past you. |

Well, apparently some of the fuzz on your screen is background radiation from the big bang. Approximately 1% if I'm not mistaken. |
