How To Build The Universe

<b>How To Build The Universe</b><br /><br />LINK<br /><br />Is causality an inherent and necessary characteristic of the Universe, or just an illusion produced by the way our brains interpret the world?<br /><br />It's real, say physicists, who believe they have worked out how the Universe is constructed from the tiniest building-blocks of space-time. The finding could also help the development of a theory of quantum gravity, which would marry the two currently estranged physical theories of the Universe: quantum theory and relativity.<br /><br />Quantum theory describes the Universe at the tiniest possible scale - about 10-³5 metres (about 10²º times smaller than the radius of a proton). It predicts that on this scale the apparently smooth fabric of space and time must degenerate into a kind of 'foam' in which connections between different points are constantly appearing and vanishing.<br /><br />Physicists have long been trying to figure out how the fuzzy nature of space-time at this tiny scale can give rise to the large four-dimensional Universe we see around us, as described by Einstein's theory of relativity.<br /><br />Scientists studying the problem assume that each tiny piece of the foam is a kind of four-dimensional triangle, with three dimensions of space and one corresponding to time. The smooth fabric of space-time can be built up by gluing these triangular tiles together, just as a smoothly curved surface can be made from flat, two-dimensional tiles.<br /><br />Because the quantum foam fluctuates through all kinds of configurations, constructing the physical Universe means adding up all the possible tiling patterns. You might think that this would inevitably generate a four-dimensional Universe - but it doesn't. Earlier researchers found that they got a space-time with either an infinite number of dimensions or just two. Neither of these looks at all like our Universe.<br /><br />Con

I bet this will turn out to be just another special case embodiement of M-Theory...<br />

zavvy- Very interesting indeed.<br /><br />BTW- you do not have to post the entire link text!<br /><br />Thank you for the link.<br /><br />So, where did that space time come from? And how was the speed of light set?<br /><br />I do agree cause and effect holds.<br /><br />I would wait for critique by other scientists before concluding this is how the universe was created.

Wow, heavy stuff, but interesting. <img src="/images/icons/smile.gif" /> Thanks for the link.
