Today we are working on the idea that there was a big bang about 13 billions years ago, and the universe has been expanding from this big bang, ever since.
Recent experiments seem to show that the universe is actually expanding faster than we initially thought. In fact the universe is actually accelerating in its expansion. There are some people who doubt these results and think they may be wrong, but for now we are working on the idea that the interpretation of the results is correct and we really are in a universe which has an accelerating expansion. Cool.
This causes a bit of a problem though. In a previous post I mentioned Newton's second law. This law basically says that to accelerate something you have to be giving it a shove, thre has to be a force. So the question then arises as to what is actually giving the universe a shove? If it is accelerating then some force must be in play.
Today we are going to talk about something that still causes, not only confusion, but a fair amount of controversy.
That in itself is amazing because it is a mystery that started about 300 years ago and hasn't really been solved yet. People have been arguing about this for over 300 years!
Today's subject of interest is wave particle duality. This is also one of the few talks were I'm going to stick an equation in. I'm only doing this because I stumbled across it a while back and I don't know what it means, if anything. I'll throw it in later.
Got a few more of these but going to take a break for a month and do somehting else! atomic and some magnetism I reckon.
enjoy.
