A Naturalistic Fairy Tale-Part XX

And then did we, Most High Scientists, run a computer simulation of the universe back many billions of years in time.  We do know you are impressed by computer simulations (praise Science).  We hope you will forget we cannot predict the weather of this planet very well more than a few days ahead.  We shall, however, present our most recent simulation and we know you will be convinced, because facts are facts.

Thus, as we did run the simulation back in time, the universe did bounce.  We did not find the singularity that we previously said was true, in favor of the now, possibly, real truth.   Because of Loop Quantum Cosmology, did we discover that there was no singularity “before” the big bang (before time existed).  So, we do now assert an infinite recycling of the universe that colapses only to a certain point, expands and then collapses again.  We hope you’ll ignore that silly research that suggests that the current incarnation of the universe will never collapse, because we don’t have to worry about those silly issues that the ID proponents do bandy about.

Bojowald’s major realisation was that unlike general relativity, the physics of LQC did not break down at the big bang. Cosmologists dread the singularity because at this point gravity becomes infinite, along with the temperature and density of the universe. As its equations cannot cope with such infinities, general relativity fails to describe what happens at the big bang. Bojowald’s work showed how to avoid the hated singularity, albeit mathematically. “I was very impressed by it,” says Ashtekar, “and still am.” (1)

Do please ignore that we have not expressed our hatred for the singularity publicly.  We do not like to dissent from known facts in that way.  We do like to dissent from our own views only when we have a better naturalistic explanation (praise Science).

Through our cunning combination of Einstein’s (very very smart fellow) theory of gravity with quantum mechanics our computers were able to discern the nature of the “beginning.”  Please do not look up the dictionary definition of tangible (2).

We did hope that the singularity would disappear, and, praise Science it has.  But don’t look for it to disappear any time soon.  We like the sound of the words Big Bang, and will continue liking it (praise Science).
