Ω Today, with no end in sight for cosmic expansion, the “Big Crunch” is out of fashion. For example, the typical cyclical models of the universe that the universe is like an accordion expanding and contracting from eternity actually implied the beginning of the universe because entropy is conserved from cycle to cycle and so each cycle was bigger than the one before it and took longer than the one before it.
Unexpected hot spots in the cosmic microwave background (CMB) could have been produced by black holes evaporating before the Big Bang. Re: Sir Roger Penrose's Cyclic Conformal Cosmology.
It is talking about what the model implies rather than what the model asserts. Just because this particular signal is there doesn’t mean the underlying model — Penrose’s Conformal Cyclic Cosmology (CCC) — isn’t right. As Penrose points out, proton decay is a possibility contemplated in various speculative extensions of the Standard Model, but it has never been observed. .” In that scenario, the universe’s sheer heft would eventually cause it to stop expanding, switch gears and shift into reverse.
This is the very similar point that Sinclair is making about the Penrose model.
That it has the evidence of contemporary cosmogony in its favor as opposed to models involving a beginning. So says a trio of scientists led by mathematical physicist Roger Penrose in a paper presenting new evidence that our universe is just one stage in a potentially infinite cycle of cosmic extinction and rebirth. KEVIN HARRIS: People are coming to your defense. —there was hope that the universe might bounce back from a “ Nevertheless, here is a delightful interview with Sir Roger on a picturesque river bank, some one year ago when he was 88 years old. The top of the hourglass is a sort of mirror image of the lower half of the hourglass. In the Beginning The Weyl Curvature Hypothesis is time-asymmetrical and it applies only to the past type singularities and not to the future singularities. Penrose popularized this theory in his 2010 book … That is just one video related to this. Within conformal cyclic cosmology, the cosmic microwave background provides the possibility of information transfer from one aeon to another, including of intelligent signals within information panspermia concept. Then the 5-dimensional spacetime of Kaluza-Klein-Maldacena in de Sitter space forms a boundary for the 4D-Minkowski-Riemann-Einstein metrics of the classical cosmology.
The interviewer quotes from the Reasonable Faith podcast “Truth, Free Will, and Cosmology” found here: http://www.reasonablefaith.org/truth-free-will-and-cosmology (links accessed December 20, 2016). , after the ancient Greek name for the fiery interludes between cycles) first proposed by astrophysicists Paul Steinhardt and Neil Turok and string theorist Burt Ovrut, later joined by Steinhardt’s student Justin Khoury. Take advantage of this. The pre-Big Bang 'bounce' of many models in cosmology can be found in a direct link to the Planck-Stoney scale of the 'Grand-Unification-Theories'. On his model spacetime is sort of like an hourglass that, as you go back in time, the universe shrinks down to this narrow neck and then it re-expands out again. Extendability by this understanding would be a technical artifact rather than an indication of past eternity.” He is saying that even though you could trace an extendible line through these different sequences or universes, they don’t really stand in temporal order to each other. Eventually everything will evaporate into light-energy (photons) and the very concept of space and time cease to exist - there is simply no scale anymore. James Zibin of the University of British Columbia in Canada points out that scientists have been scrutinising the CMB for years and have found no evidence for particularly hot spots (although they have identified one anomalous cold patch). The Holographic Universe of Susskind, Hawking, Bekenstein and Maldacena plays a crucial part in this, especially as M-Theory has shown the entropic equivalence of the thermodynamics of Black Holes in the quantum eigenstates of the classical Boltzmann-Shannon entropy mathematically. This is the very similar point that Sinclair is making about the Penrose model. I think this topic just boggles the mind. “Obviously, if someone could show that some specific pattern on the microwave sky was a proof that the universe underwent a series of cycles then that would be spectacularly exciting,” he says.
repeated Big Bounces I’m glad because when you read headlines like one blogger – “William Lane Craig is either lying or getting things very wrong” – it is inflammatory. Then the 'phase spaced' de Broglie inflation is in moduar quantum entanglement with the Weyl-Wormhole of the Zero Curvature of Roger Penrose's hypothesis. Sinclair thinks that this same problem attends the conformal cyclic cosmology.
The Hawking points would then have stretched during the early universe, forming circular patches with a diameter on the sky about five times that of the Moon.

It is a model of a sort of branching universe that has an origin in the neck and then you have two universes emerging each with its independent arrow of time from that common origin point. The Hubble-Universe consists of 'adjacent' Weyl-wormholes, discretisizing all physical parameters in holofractal selfsimilarity. These times within each universe are incommensurable.
