Where Did We Come From? [2]

Dots on a balloon!

What did Mr Hubble mean by "everything moving apart?"

See "Where Did We Come From [1]" (click on extract, right). Take a balloon.

Balloon? A balloon to explain about creation and God?

Take a balloon and draw some dots on it with a felt tip pen.

Now blow it up and see what happens to the dots.

Hey, big inflation! Everything moving apart. But How did he work this out? Surely not from a telescope?

He spotted the "red shift"

Isn't that a sexy frock?

No comment! Pay attention and I'll explain. If you listen to a fast car going past, like on a race track, It goes "yeeeeeee...aaaaaaaaaaar!", the sound has a higher note as it approaches and a lower note after it has gone.

Please, pretty please, I know. It's called the Doppler Effect.

Named after Christian Johann Doppler (1803 - 1853). It's the same for light. If the object is moving very fast (near the speed of light) It looks red. Red is the "lower note" or longer wavelength of light. Hubble saw that the galaxies that were further away looked red.

He suggested that they were all moving away from each other and moving very very fast!

So that first start-up lump must have been very big, then?

Hmmm, not so fast. Clever cosmologists, physicists and mathematicians started doing some very tricky sums and then it started getting really interesting!

So there WAS a beginning? But could Mr Hubble PROVE it? And it doesn't seem to have much to do with God.

But we are making progress. The first three words of the Bible are 100% scientifically accurate! Not much, but it is a start.

 In the beginning , when God created the universe, the earth was formless and desolate.
