Like many positive terms, the phrase “big bang” originated as a pejorative. Fred Hoyle coined the term in 1949 as a way of deflating the concept of an expanding universe. It stuck, even after Edwin Hubble showed that 13.7 billion years ago, all of the matter in our massive universe was indeed compacted into “one superdense ball.” Astronomers have also figured out that the volume of the big bang was only 120 decibels, about the loudness of your average rock show (though how there might have been sound without an atmosphere escapes me). There is some irony in Hoyle’s dig: the “big bang” wasn’t particularly big, and wasn’t much of a bang, but it happened.
We learn all this and more in the video above from The Open University, and all within a minute, as the title of the series, 60 Second Adventures in Astronomy, promises. These amusing animations are very much like other OU series we’ve featured in the past: 60 Second Adventures in Economics; 60-Second Adventures in Economics: and 60 Second Adventures in Thought. (Find them all on iTunesU here.)
The university describes the new astronomy series like this:
Ever wondered where the Universe came from? Or more importantly, where it’s headed? Voiced by David Mitchell, this series of twelve 60 second animations examines different scientific concepts from the big bang to relativity, from black holes to dark matter. The series also explores the possibility of life beyond Earth and considers why David Bowie is still none the wiser about life on Mars.
Spend a few extra minutes educating yourself with some more 60 second astronomy adventures below, or visit the complete collection here on YouTube or iTunesU.

The Big Bang was the beginning of the universe about 13.8 billion years ago when everything started expanding from a tiny point.
Supernovae are huge explosions that happen when big stars die, spreading
elements like iron and oxygen into space.
Exoplanets are planets that orbit stars outside our solar system, and some might have conditions where life could exist.
Special relativity is Einstein’s idea that the speed of light is always the same and that time can change depending on how fast you’re moving.
An event horizon is the edge of a black hole where nothing, not even light, can escape.Scientists are interested in Mars because it has signs of ancient rivers and water, which means it might have once supported tiny life forms.Astronomy is the study of space, stars, planets, and everything in the universe.The Big Bang was when the universe started expanding about 13.8 billion years ago.Relativity is Einstein’s idea that time and space can change depending on how fast something is moving.
