Hey,
Nice pictures, btw have you seen GPP mentioned in her paper? or any of Rovelli's ones besides that one with Mike?
Interesting they were discussing in May04 isn't it?
There has been another paper recently I'm not sure you have seen by Dolby and the Page-Wotters approach. That papers...
Hey,
This is probably my last post for a while but I want to say something before checking what is going on at home (I just took a looooong nap :) ). I'd like to recommend anybody to take a deep breath and read the papers carefully. I am not saying that you, marcus and selfadjoint, didnt...
Today is election day in my native country (Uruguay) and I am quite excited about the possibility that for the first time in 174 years the left party will win the election. I am nowadays in US and its been quite dissapointing not to listen a single word from either Kerry or Bush about south...
Hey,
The meaning of time by itself is a rather subtle issue it would take lot time to discuss. What I can say is that think of $n$ as coordinates in GR since actually they are just a discrete counterpart. In classical GR, as Einstein pointed out, coordinates are just labels and physics is...
Hey,
Just a remark, Gambini and Pullin have each more than 110 papers. They have contributed to classical GR as much as QG.
Gambini indeed was amongst the first to introduce loop space in gauge theories in the early 80's and he has done important contributions to lattice YM theories as...
Hey,
Yes Marcus I'm aware of those papers too. With respect to the differences between consistent discrete quantum gravity (Gambini-Pullin approach) and LQG I would say that the main difference is the disappearance of the space-time constraints (Internal constraints, like Gauss law, is...
hi guys, I just wanted to say that relational time not just works, is the "only" way to construct a consistent, realistic physical theory! You may want to take a look to these papers (I am sure Marcus will like them :))
