Hi everyone, have been busy reading " A brief history in time" (four times in fact) and researching articles on relativity on the net. I have deduced that this book is best read and understood whilst sitting on the toilet- this being a quiet place to read without being disturbed. I haven't resorted to taking drugs(other than legal ones) to understand relativity, but it certainly takes some mind elasticity. An article I found useful was "Albert Einstein's Theory of Relativity- In Words of Four Letters of Less" at the following website
www.muppetlabs.com/~breadbox/txt/al.html .
Now for some thought benders,
Einstein said that gravity is a fake pull, and that the earth doesn't veer constantly to circle the sun but that instead the earth travels in a straight line in space and that space-time is bent by the sun's mass. This means that in our three dimensional existence the earth appears to curve around the sun, but in fourth dimensional space-time it is in fact travelling in a straight line. Next he says that no true body is at rest, if I hold a ball in my hand and let it go, who can say that the ball moves towards the earth? It holds just as true that the ball stays put and that the earth moves up to the ball. I understand the theory but it doesn't pass the commensense test. Any thoughts from any intelligent beings out there?
