Discordianism is based on pantheistic idea, that chaos is all that there is, and that order and disorder are both illusions (a multiple-ego solipsism).
- More is different (Aug, 4, 1972)
P.W. Anderson suggested the fundamental principle of emergence, i.e. that ‘More is Different’, meaning that complex physical systems may exhibit behavior, that cannot be understood only in terms of the laws governing their microscopic constituents. Later this claim was strengthened by proving that many macroscopic observable properties of infinite periodic Ising lattice cannot in general be derived from a it's microscopic description.

T.A. Jacobson found equivalence Einstein field equation of general relativity and thermodynamic state equation ΔQ=TdS connecting heat, entropy, and temperature by using a Raychaudhuri equation and the proportionality relation between area and entropy for acceleration horizon. This perspective was generalized recently by Brustein and Hadad and it follows to Universe model composed of ideal Boltzmann gas, for which enthropy was defined originally.

- New Theory: Universe Was Born in a Black Hole (17 September, 2003)
Blake Temple says, the universe will emerge from all this as something like an exploded star, called a supernova, but on an enormously large scale. Einstein's equations work equally well if time runs forward or backwards. But explosive shockwaves, which include an increase in entropy, are time-irreversible. The new theory satisfies Einstein's equations reportedly, while allowing universe to expand. Compare recent podcast of Brian Greene.
- Spacetime and strings as an emergent phenomena (October 9, 2004)
Ed Witten: "One thing I can tell you, though, is that most string theorist’s suspect that spacetime is a emergent Phenomena in the language of condensed matter physics". Well, not all of them, but it doesn't change the point.

Garrett Lisi is publishing a paper on his "An Exceptionally Simple Theory of Everything", based on explanation of particle generations by rotation of E8 Lie group, describing the most dense arrangenement of particles, formed by density fluctuation of another particles, recursivelly. (a more detailed NS article, a L. Motl's comments)

Silke Weinfurtner in his thesis disputes a possibility, that perfect fluid sphere geometry of spacetime may be an emergent phenomenon, which has been motivated by the Analogue Gravity programme.
- Inhomogeneous Vacuum: An Alternative Interpretation of Curved Spacetime (14 Jan, 2008)
After one hundred years after Einstein's “refractive” approach to gravitational light-bending and seventy years of first gravitational lens observation, strong similarities between the light propagation in a curved spacetime and that in a medium with graded refractive index were re-vealed. It was pointed out, that a curved spacetime is equivalent to an inhomogeneous vacuum for light propagation.
- Fiber-Optical Analog of the Event Horizon (March 7, 2008)
This experimental work demonstrated, that physics of vacuum at the event horizon is analogy to spreading of waves in moving media and event horizons are formed where the local speed of the medium exceeds the wave velocity. By sending of ultrashort pulses into foamy structure of optical fibers was demonstrated the blue-shifting of light at a white-hole horizon and that system is capable of probing the quantum effects of horizons, in particular Hawking radiation.
- Using Causality to Solve the Puzzle of Quantum Spacetime (June 25, 2008)
If we think of empty spacetime as some immaterial substance, consisting of a very large number of minute, structureless pieces, and if we then let these microscopic building blocks interact with one another according to simple rules dictated by gravity and quantum theor, a new approach to the decades-old problem of quantum gravity goes back to basics and shows how the building blocks of space and time pull themselves together. (readers response).

Some physicists (especially those interested in LQCD) theorize, that space is highly structured by the grid, which is the primary ingredient of physical reality and the substance from which all physical matter is formed. F. Wilczek says, the grid is a conceptual descendant of ether, that mysterious substance scientists once believed filled empty space.
- Why Einstein was wrong about relativity (October 29, 2008)
Mitchell Feigenbaum insists that Einstein's theory has nothing to do with light - whatever history and the textbooks might say. "Not only is it not necessary," he says, "but there's absolutely no room in the theory for it." Compare the R. Close's derivation of Lorentz transform by using of clock, based on wave spreading. By AWT the position of light is still somewhat special, as it forms the fastest interaction, mediating the causal information spreading for us.

New Scientist's article disputes the idea, proposed three years before, the large black holes were formed before galaxies (a "dark energy star" concept is still considered in this connection, though).
- A bizarre universe may be lurking in the shadows (March 04, 2009)
By AWT antimatter never disappear from observable Universe, it was only finely divided (evaporated) into streaks of dark matter. This prediction was presented a two years before and now recent ATIC and PAMELA observations seems to support it, while interpreting the source as a result of WIMPs anihillation (compare the AWT explanation here).
- Remarks on the world-sheet saga (Jun 11, 2009)
From Schroer's general reasoning follows, only 0-dimensional particles are acceptable building blocks in physics. So string theory must be a theory of point-like particle fields with infinitely many components, too. It follows that one can never include winding modes even if the target space is not simply connected and there is no T-duality.
- Mimicking celestial mechanics in metamaterials (July 20, 2009)
In this experiments it has been proposed a link of energy spreading through GaInAsP metamaterial sponge to celesial mechanics, the spreading of light through vacuum in particular (formation of event horizon a photon sphere of black holes, etc.. - compare the AWT explanation here).
- The invariant set postulate (June 29, 2009)
Tim Palmer proposes a new geometric framework for the foundations of quantum theory and the role played by gravity based on assumption, observable reality forms a smaller fractal subset of states in more general state space (supposedly in simmilar way, like observable density fluctutuations of gas are forming subset of many uobservable states of individual molecules).

How ancient physics was reborn
Main purpose of this post is just to track rather fast re-introduction of ancient Aether model (possibly under influence of AWT concepts) into mainstream science again by using of online available sources. Therefore only links to other articles with minimal comments will be presented here and the list will be extended gradually regarding to public proposals:
