Dear ChrisisC, Since gravity is not a "real" force, but relative to the observer, it seems to me dificult unifying it with the tree known real forces, already unifyed. Tollendal

I suppose not in book form, but in the Internet the matter is abundantly discussed. See, for instance: http://news.fnal.gov/2015/12/holometer-rules-out-first-theory-of-space-time-correlations/

Dear windy miller, You are right, of course, the Universe existed forever or had a beggining. Lawrence Krauss showed that a beggining from nothing is possible, but nothing shows that it occurred 13,8 billion years ago, as It could be cyclic. A matter very difficult to decide, if the decision...

Dear glOWyrm, It seems to me Dr. Craig Hogan's experiments in Fermilab ruled out the cherished theory of Leonard Susskind exposed in his recent book "The Universe From Nothing". Time and space are not granular. https://holometer.fnal.gov/

Dear Quantum of Solace, Why couldn't we accept the reiteratelly verification that Universe isn't local? That simple act of humility would simplify so much the discussion! Suppose I take a pair of gloves and put each of them in a box. I keep one with me and give the other to you, who then take...

Has a Hungarian physics lab found a fifth force of nature? Attila Krasznahorkay at the Hungarian Academy of Sciences’s Institute for Nuclear Research in Debrecen, Hungary, and his colleagues say they spotted an anomaly in radioactive decay that could be the signature of a previously unknown...

Dear windy miller, Sometimes it seems to me that almost all Physics students really are Mathematics lovers. They forget that Mathematics deals rather well with infinities, but in Physics they generally signify that a theory is incomplete, has reached the limit of validity. So, singularities...

Dear iDimension, Dark energy is an infortunate name, as physicists so frequently love to do. It's synonimous to the expansion of the Universe, about whose causation we know nearly nothing, but the name helps to confuse the theme with the well known concept of energy and so promotes much desne...

Dear DoubleD, The significance of the Wave Function was not understood until Max Born interpreted it as defining the probability of finding a particle in a determinate position of space. He received the Nobel Prize for it in 1932. So, if you call a probability something "physical", the choice...

Dear wannaberadiologist, As you know, in 1926 was formulated by Erwin Schroedinger a partial differencial equation that describes how the quantic state of a physical system changes with time. For it, in 1933, he received the Nobel Prize (together with Paul Dirac). It contains the factor Ψ...

Dear nasu, I thank you very much your kind observation. In my view the most relevant thing about the new research is that it seems to establish a new fundamental limit in Nature, somewhat analogous to c. Absolute zero temperature can't be reached, but can be surpassed! I'm transposing this...

Dr. Achim Rosch, a theoretical physicist at the University of Cologne in Germany, who proposed the technique used by Dr. Ulrich Schneider and his team to create in laboratory negative absolute temperature, have calculated that whereas clouds of atoms would normally be pulled downwards by...

Dear athosanian, That's in somewhat loose wording was Dr. Aephrain Steinberg (University of Toronto - Canada) has done. More rigorously, you can read it in "Observing the Average Trajectories of Single Photons in a Two-Slit Interferometer" - Science 3 June 2011: Vol. 332 no. 6034 pp. 1170-1173...
