Across the universe
When we look up to the black sky at night
We see the stars and planets back in time
The moonlight's only one second old light
While sunlight, that's eight minute old sunshine
Eight minutes to reach Earth despite flying
As fast as light can. Alpha Centauri
The next nearest star, is - no point lying -
4.3 years old by the time we see
It from our vantage point. It's history
Look through a telescope at distant sights
Like Andromeda, you're seeing a time
When man was still evolving, odysseys
Still to come. What we see further out might
No longer exist. The whole thing's dying...
This was inspired by 'Journey To The Edge Of The Universe' which I saw last night. I love anything which helps to explain the nature of time - or the illusion of time, as I would (controversially) qualify. For instance, they say that we 'go back in time' the further out we go into the distant universe. No, incorrect. We go back in time the further out we LOOK into the universe FROM HERE, which is what they mean, and which is what I describe in this sonnet.
Incidentally, some (very) hot news. Andromeda, according to them, will crash into the Milky Way in about 2 to 3 billion years' time. That's in addition to the sun expanding into a red giant and burning the Earth to a cinder, of course. So it's no good talking as they did on the programme about finding new habitable planets within this galaxy or the next then, is it? Since they're 'about to' collide. Nah, better get our skates on and go a few billion light years further out, I reckon.
