by quantizing the basic equation of cosmology

and developing a quantum cosmology

Bojowald already in 2001 showed that there is no singularity

at the big bang.

the model extends back further in time

 

it quickly converges soon after the ex-singularity to

resemble classical spacetime

 

Bojo model is called LQC, loop quantum cosmology.

 

It even naturally generates an inflationary episode

immediately after the crossover from contraction to expansion

and a graceful exit from inflation, which is generic

in the model---i.e. requires no elaborate extra assumptions or fine tuning.

 

Bojo is 31. He has revolutionized cosmology by constructing the first

quantum model that really works (and matches the semiclassical and

classical pictures as soon as you get far enough away from singularity)

 

It is about time that Nature journal had a page on Bojowald

 

His current work investigates the quantum regime that replaces the

classical Black Hole singularity

I have a question about LQC. Is there inflaton (a scalar field) in this theory?

Yes.

 

since I am merely someone watching the field (not an expert) I will

refer you to some papers by various people

I will have to look up the arxiv numbers and edit them in here
