thanks lawrence,
you seem to write many thinsg without really signifying anything. for instance, you write:
"Gravity may not quantize effectively beyond the one or two-loop limit."
do you mean to see that
a) gravity has been quantized at the one loop limit
b) gravity has been quantized at the two loop limit
c) gravity has been *effectively* quantized at the one loop limit
d) gravity has been *effectively* quantized at the two loop limit
e) gravity has been quantized at the one loop limit but it has not *Effectively* been quantized at the one loop limit.
f) gravity has been quantized at the two loop limit but it has not *Effectively* been quantized at the two loop limit.
e) gravity has been *effectively* quantized at the one loop limit but it has not been quantized at the one loop limit.
f) gravity has been *effectively* quantized at the two loop limit but it has not been quantized at the two loop limit.
Gravity on the quantum tree level, with internal graphs of order ħ is not at all hard to quantize.
So do you mean that you have quantized gravity?
"If this is done on the post-Newtonian level is not much different from quantizing Maxwell's equation."
What do you mean by post-Newtownian level? GR? How, if done on a different level, is it different from quantizing Maxwell's equations? When you say that it is " not much different from quantizing Maxwell's equation," what are the differences?
"I will say that I think fundamentally something else takes over from gravitation as the quantum field, but that is a bit of a long story."
Where can I find this long story? What takes over from gravity? Have they measures/found this yet?
"In this way quantum gravity is not some exponentially difficult nest of perturbative terms, but is a soliton dynamics. However, LQG may provide some answers for how quantum gravity should look at the O(ħ^2) level."
You say that LQG "may provide some answers for how quantum gravity should look at the O(ħ^2) level."
What percentage chances would you ascribe to your use of "may." 10%, 50%. .0001%?
That would be great if you could please provide some equations to show that LQG quantizes gravity as after researching this on the web, it appears that LQG fails to quantize gravity in any way shape or form.
I would be happy to provide you links, if you could please provide me with definitive equations of LQG.
