How space might emerge from a purely quantum picture of the world -- a new paper.
http://www.preposterousuniverse.com/blog/2016/07/18/space-emerging-from-quantum-mechanics/
The other day I was amused to find a quote from Einstein, in 1936, about how hard it would be to quantize gravity: “like an attempt to breathe in empty space.” Eight decades later, I th…

What was one of the first things Christians did after suffering 300 years
of persecution at the hands of the Romans? When Emperor Constantine
created the Holy Roman Church, they persecuted non Christians. A group of
good Christians chased down and flensed the skin off of a woman until she
died right out in public for everyone to see.
Most everyone is looking for someone to victimize. They're just waiting
for someone else to tell them it's OK to do so.
You don't call me dumbass in the name of Jesus. He would be sickened by
such vulgarity. Plus there is the whole Vengeance is mine sayeth the
Lord, and Judge not lest ye be judged and found wanting etc.
You call me dumbass because you want to be better than me or whomever else
you can. It is the poorer side of human nature.
Well, I don't care really. If I burn as you say in hell so be it. I
really doubt that will be but so be it.
And you can be Christian and ridicule me for not being. Doesn't change
anything in my life.
Have a good one.

Gerard 't Hooft @gthooft on Nature's bookkeeping system: where the degrees of freedom are. (h/t +Sabine Hossenfelder)
http://arxiv.org/abs/1605.00027
Abstract: Establishing how one should describe and study natures fundamental degrees of freedom is a notoriously difficult problem. It is tempting to assume that the number of bits (or qubits) needed in a given Planckian 3-volume, or perhaps 2-volume, is a fixed finite number, but this ansatz ...

I checked a bit and found this discussion with 't Hooft regarding quantum mechanics. I don't know string theory but and only had a quick look but this approach seems to be about hidden variables and classical determinism?

Another good article from Quanta Magazine. I like their approach of not oversimplifying compared to some other sources for the general public.

The always-interesting Scott Aaronson on quantum mechanics, computers, gravity, utopia, and hard problems.
http://blogs.scientificamerican.com/cross-check/scott-aaronson-answers-every-ridiculously-big-question-i-throw-at-him/ …
Quantum-computer whiz riffs on simulated universes, the Singularity, unified theories, P/NP, the mind-body problem, free will, why there’s something rather than nothing, and more.

Space emerges from quantum mechanics! Here's the paper, I'll try to explain more comprehensibly later.

To be more honest, he was the father of Big Bang Creationism. The idea that our universe is expanding from a very small single source is his idea. Others, later, postulated that the beginning could have started from an area much smaller than an atom, some even postulating from "nothing." Now if that isn't creationism of a new sort I don't know what is.

The cosmological redshift should be thought of as a distance only effect, just as Edwin Hubble believed as the best explanation of the data.

Buckets of raw data (well, 300 terabytes) from particle collisions have been released to the public by CERN.

Yesterday, the European Organization for Nuclear Research (CERN) dropped a staggering amount of raw data from the Large Hadron Collider on the internet for anyone to use: 300 terabytes worth.

I would like to ask a question for, which I couldn't find a reasonable answer...I hope you could you could give me a genuine reply. E=mc2 or E=mn, according to this theory ;energy cannot be created nor destroyed but can be transformed from one State to another then how did energy come into existence without its creation.
