Bang – or NOT to Bang
Anyone in the mood for some really DEEP stuff? If so, read on. I’ve always been pretty keen on the big bang theory, though I never could get my head around how you could get something out of nothing – as it goes against all the laws of physics which have worked so well for us in practice. The expansion I can handle – it’s the stuff popping out of no-where I’ve never really been comfortable with – of course if you’re happy with the notion of multiple dimensions it’s all very simple – our universe appearing as a constantly expanding bubble to us – is merely a manifestation of a universe with more dimensions.
Ok, where does that come from – the usual way to picture this is – picture a flat, 2 dimensional man on a flat, 2 dimentional universe – ie a piece of paper – he can see across in any direction but not up or down – so – if a large ball smashes through his piece of paper and managed to do that cleanly – what will he see? He’ll see nothing turn into a point and then into a line that gets wider and wider…. and then gets narrower and narrower – and disappears.
That’s kind of how I pictured the big bang – assuming we’ve always been here – and that we’re part of a larger picture we can’t see as we’re only capable of operating in 3 dimensions (4 if you include time).
Ok, kiddies version I know but with limited time to think about these things – that’s where I was heading until now.
My OTHER problem has always been the sun – how come it’s hotter above the surface than it is on the surface – and how come sun spots are cool!! If the sun is a huge nuclear reactor – surely when it spurts bits out they should be hotter and brighter than the surface and above??
Sadly as one gets older there seem to be less and less people to talk to about this stuff – but there is always the web.
Ok, so then recently I was sitting playing with STUMBLEOPON and I hit a theory of the universe from an electrical perspective… and BOY do things change.
If you’re interested in this stuff you REALLY should take a look at this video.
