Writing about infinity presents endless possibilities. Most of my scientific understanding comes from listening to BBC Radio Four while doing the housework or cooking. The Infinite Monkey Cage is a programme combining comedy and science which I can understand, then there was the serialisation of Professor Stephen Hawking’s last book Brief Answers to Big Questions; if I didn’t take that all in I blame it on domestic interruptions or a noisy washing machine.
Here is my handy guide to the universe. I think Stephen Hawking said the universe is growing, therefore at one time it must have been smaller and long ago so small it was nothing; one minute it was nothing and the next minute there was a big bang. I prefer my theory that if the universe is infinite it will go on forever, so it must have always been here forever.
But how big is infinity? The edge of the observable universe is 46.5 billion light years away, but we can’t see if there is an edge to it or work out how much more of it there is. Apparently even clever scientists, who can cope with the thought of billions of light years, still find infinity a bit creepy. They are no different to young children ( or was that just me? ) who ask ‘Who made the universe?’
‘God’ the parent replies and then they ask
‘But who made God’ or ‘What’s outside the universe?’
Another theory is that the universe could curve round on itself, making it both finite and infinite. Could that mean time goes in a circle and if we crossed the circle with a diameter or a chord we would be in a different time, thus making time travel possible? But is time merely an illusion? If so, time travel is still on the cards…
Talking of space, there is a lot of space between atoms and inside atoms; if you took all the empty space in the atoms that make up a human being, a person would be a lot smaller than a grain of salt. If you removed all the empty space from the atoms that make up all the humans on the planet, we could all fit inside an apple. If we removed the spaces between and inside all the atoms in the solar system it could fit it inside a thimble, so perhaps the universe is not so big after all.
Whatever the truth, authors who enjoy writing about time travel are never going to concede that time travel is impossible. Science fiction writers in general vary from those who are scientists to those who make it all up and who can prove them wrong if they set it in the future; unless a book reviewer travels to the future to check…
If you want to stretch your mind and go somewhere different why not dip into Someone Somewhere.

Perhaps it is indeed a mobius strip. 😀

I had to look that up – ah yes, I have knitted one, a mobius strip makes a good neck warmer and an excellent universe!
