Red Shift - fascinating!
Its the evidence that the universe is expanding I think
They're all running from us
The scary bit is that it might impolde on us though
Or it could just continue expanding into nothing.. but if space is nothing, what are we expanding into?? Its really confusing.
And the idea of the redness of the sky at sunset..
Is it similar to why water is blue?
Because the density of water makes the higher frequency (light) waves through?
That and the reflection of the sky
