Smolin knows much more than me on this matter. If I'm honest then I've to admit that I know very little about Causal Dynamical Triangulation. I have heard a little about this theory. I also want to inform to the readers of this blog that many things that I wrote and I will write here could be wrongs, Sorry. Zephir, thanks for your wise notes. I'm going to read a lot on this matter and I will try to learn more. My intention wasn't put it lightly, sorry :-(.<br><br>I didn't want to say that LQG can't account for inflation, I just wanted to say that LQG can´t account for the rate of inflation.

The picture bellow is his own illustration of that process, so I suppose, he knows, what he's talking about.<br><br>http://superstruny.aspweb.cz/images/fyzika/lqg/lqg_simplex.gif<br>http://superstruny.aspweb.cz/images/fyzika/aether/elastic_foam.gif<br><br>This doesn't say, indeed, the LQG is quite exact description of real Aether foam behavior.Zephirhttp://www.blogger.com/profile/06010623752049244967noreply@blogger.comtag:blogger.com,1999:blog-2266478817448155510.post-24897322301235958042008-09-08T13:49:00.000-07:002008-09-08T13:49:00.000-07:00Zephir,You wrote:"The concept of Aether foam ...Zephir,<br><br>You wrote:<br><br>"The concept of Aether foam covers the quantum foam or spin network of LQG theory<br>as the correspondence principle requires"<br><br>This assertion is of paramount importance. Let's see it.<br><br>I've never been committed to the idea that LQG describes the quantum gravity in a correct way. As you know, LQG is a proposed theory for quantum gravity and it's background independent. It's formulated on a Quantum Geometry which is described mathematically by means of Spin Networks. The Spin Networks evolves over time and forms a Spin Foams, i.e. the Spin Networks can be considered the boundary of the Spin Foams.<br>Suppose the simplest case, namely, a space with a single node. Some line segments come out from this node and these line segments also finish over the same node, i.e. the line segments form loops. Well due to Heisenberg's Uncertainty Principle, the spin network must evolve and new nodes arise. If new nodes wouldn't arise then we can to fix the space and linear momentum at once and this violates the Heisenberg's Uncertainty Principle ;-).<br>Therefore the space is expanded. But, at start of time, the big bang can be modelled with this simple space (space with a single node) and the inflation can be modelled by the expansion of space (emergence of new nodes). Well, to date, why has anyone made precise calculations and has derived the rate of this expansion? Because, I think that this model doesn't work and the inflation can't be explained using LQG. The inflation is seen likely in the current cosmological models. About string theory is better don't talk. From my viewpoint, the best and most simple theory to explain QG (without taking into account AWT) is described in the Weinfurtner's paper, (namely Emergent spacetimes).<br><br>The best.curious-awtnoreply@blogger.comtag:blogger.com,1999:blog-2266478817448155510.post-50138794600197485412008-09-08T08:05:00.000-07:002008-09-08T08:05:00.000-07:00Zephir, Great Idea, We can try to found a mathemat...Zephir,<br> <br>Great Idea,<br> <br>We can try to found a mathematical background for AWT by means of Complex System Theory. Maybe there are in this theory very good tools to describe the AWT mechanics. In an equivalent manner, we can use the intuition that we have about AWT to achieve many breakthroughs in Complex System science. <br>One question, Do you think that Change Climate is a pseudoscientific field?<br><br>I have always thought that we could consider the Change Climate like a scientific field if we dealt it adequately.curious-awtnoreply@blogger.com
