My local TV station has been showing World Science Festival, TED, and some other science shows. It’s fascinating to hear the accepted theories on how the universe was created, stars, black holes etc. From what I understand our universe is thought to be a little under 14 billion years old, which is a staggering length of time …
Some of the other quantities like the number of stars (10-200 sextillion) and number of planets they think are in our universe are even more vast, so vast in fact it’s pretty challenging to comprehend things like – there are (perhaps) more stars in our universe than grains of sand on all the beaches on earth.
From what I understand, our universe is expanding, has been since the beginning. It’s what scientists call “inflation”. Liking to think beyond what I’m told, I do puzzle about what exactly the universe is expanding into.
