Anyone who knows anything about the cosmos will know that it is vast – I hope I don’t need to tell my readers this still however the vastness of the whole thing, but I found a really good video that I think will make you think – it’s only 6-7 minuets and best viewed on full screen.
I think videos like this are great because they put you back inside your box. As humans we have a tendency to think that we are in some way important, and that our country is very important and that our world is very important. But you really don’t need to zoom our far before you cannot see it at all. As you will see from the video, there is a huge amount of zooming that you need to do after you can no longer see the sun in order to get to the scale of what we know. The words what we know are very important there – because there are very few physicists worth their salt who think the known universe = the universe. We have made huge progress in science in the history of humanity – but we are but a fraction of our way through.
I remember something Tyson de Grasse said once, that if we were to condense the entire history of the universe into a calendar, a year long calendar, that Jesus was born a few seconds before midnight (sorry if that offends, but if it does you’re in the wrong place). The entire human history in a few seconds. When you start to play around with the scale of the things we are talking about I challenge you to look at the world in the same way again. We are part of something very very big.
