sorry for my late reply but i haven't had the time to address the questions properly before. I know that people like Penrose and Carroll have issues regarding the apparent ability of inflation to explain the low entropy near big bang, i wrote it in the first line of my first post, my question is...

the reference to Seth Lloyd mostly regarded the interpretation of entropy as information, these links on arxiv can be relevant to that (i haven't read them yet): http://arxiv.org/abs/quant-ph/9908043 http://arxiv.org/abs/quant-ph/9612034 i read about the implications of information theory...

Regarding the problem of the low entropy state at the big bang, people like Penrose, Page, Carroll etc. do not think that inflation solves the problem. I recently read and listen to Seth Lloyd and his explanations about the beginning of the universe from the point of view of entropy as...

light interferometry as described in Thorne's "black holes and time warps"? hello, maybe someone who read the book can help me with this, but i'll give all the information so that even someone who hasn't read it can understand. At page 383 and following, and at fig. 10.6 and box 10.3, Thorne...

First i have to admit i haven't a comprehensive knowledge of Bohmian mechanics but, for what i know, i consider "dark spots" of the theory: -probably the most common critic to the theory, the strong non-locality that implies, and that seems to contradict special relativity as it implies...

It took me some time to reply, mainly because i am not well acquainted with maths and mechanics. Anyway, from what i understood of hamiltonian mechanics, in a classical world i could describe it as a way to compute the physical proprieties (dependant on the transition from/to potential/kinetic...

Thanks again Demistyfier, i would rather not mess with philosophy, but i think this is one of those cases that stands at the boundaries and can't be ignored. The way i see it, the wave-function has no actual physical counterpart and yet it has an active physical role per sé in entanglement...

thanks Demystifier for your answer. Which interpretation of QM is fully "materialistic"? I can only think of Bohm's interpretation but, just because (in my understanding) it assumes the reality of the wave-function in the physical world (maybe even inside space-time?), i don't like the strong...

Hello, i have a question regarding the Many World Interpretation of quantum mechanics and how it explains the entanglement of two particles.. From my understanding, entangling two particles so that an observable of one (es. spin of z axis) is correlated with the same observable of the...

hi everyone, i am no physicist so i only have a slight understanding of these matters. I just finished reading Greene's "elegant universe" and i understood that in "classical" string theories there are 6 compactified dimensions along with our familiar 3 extended spatial dimensions + time...

hi everyone, i am not a physicist, so please forgive me and help me to clarify some basic concepts. in the context of the inflation of the universe, as i understand it, it was the energy density of the void that expanded space-time, so that the energy density remaining (almost) constant coupled...
