"Are we Seeing Signals from Before the Big Bang?" - Professor Sir Roger Penrose OM FRS
About | Information | History | Online | Facts | Discovery
Abstract: In 2005 I proposed the unconventional scheme of conformal cyclic cosmology (CCC). This takes what is currently regarded as the entire history of the universe, from its Big-Bang origin (with no inflationary phase) to its final exponential expansion, to be but one aeon of a continual succession of such aeons. The big bang of each is taken to be an infinitely scaled down continuation of the exponentially expanding remote future of the previous one. A positive cosmological constant (dark energy) and some primordial scalar material (dark matter) are both essential to CCC's consistency. Supermassive black-hole encounters in the aeon previous to ours would have observational implications for CCC, detectable within the cosmic microwave background. Recent evidence of such signals in both the WMAP and Planck satellite data will be presented. About the Speaker: Sir Roger Penrose OM FRS, is a mathematical physicist, mathematician and philosopher of science. He is the Emeritus Rouse Ball Professor of Mathematics at the Mathematical Institute of the University of Oxford, as well as an Emeritus Fellow of Wadham College. Penrose is known for his influential work in mathematical physics, in particular for his contributions to general relativity and cosmology. He has received a number of prizes and awards, including the 1988 Wolf Prize for physics, shared with Stephen Hawking for their contribution to our understanding of the universe. Popular science works include The Emperor's New Mind, Shadows of the Mind: A Search for the Missing Science of Consciousness, and The Road To Reality.

Yes, draw nice little pictures. This theory was discussed long ago and discarded. Show evidence,extraordinary evidence for an extraordinary claim. If the universe repeats so much..when did it start and god doesn't count.
-
what about the firewall? hawkings states that its an inferno i.e hot as fuck??
-
With the recent Nobel price (2016) in physics in mind, could the trigger for the next cycle to be started be a topological change in spacetime itself? The spacetime seen as a cold quantum fluid that finally gets so cold in distant time that a phase change takes place?
Sorry if it sounds loony, but the thought just occured to me while reading about the physics nobel prize :-) -
The universe looks like a thong.
-
Entropy always increases (except for during the production of crystals and galaxies of course).
-
this is good i like the drawings its easier own the eyes and gives you a break from modern lecturers.its nice to have to use you imagination instead of a computer doing it

I honestly can't understand how can some people complain about his drawings, which are absolutely beautiful and explanatory. For Penrose drawings are fundamental tools for both understanding and teaching complex mathematical concepts, they are central to his work. Someone might want to take a look here:

Of course we would benefit from zooming on those drawings, but that's another story.
Anyway, I have the feeling that those who can't appreciate Penrose might likely enjoy deGrasse Tyson's videos -
My oh my does this man Bumble so much of the time away. His "old school" learning really shows by HAND WAVING, drawing pictures and excluding math to explain the early universe. I have never heard this man's name much and when it was rarely mentioned outside of the U.K. (reminiscent of Tim Henman) no respect was conveyed, nor are any of his ideas taken seriously and it totally shows why. His analysis, if it qualifies as one, reminds me of how a 5th grader would tackle these issues.

Yes another mad scientist so smart he can't operate a mouse or projector. Incredible.
-
Such a legend but he really needs to give up his attachment to old school teaching tools. Someone buy him a laptop and some lessons for science sake.

According to Hindu mythology, the universe was created with a sound: “Om.” It’s a syllable that contains within it everything that ever was and everything that will be. When the Arecibo telescope is pointed at the space between stars, it hears a faint hum. Astronomers call that the “cosmic microwave background.” It’s the residual radiation of the Big Bang, the explosion that created the universe fourteen billion years ago. But you can also think of it as a barely audible reverberation of that original “Om.” That syllable was so resonant that the night sky will keep vibrating for as long as the universe exists. When Arecibo is not listening to anything else, it hears the voice of creation. Ted Chiang, ‘The Great Silence’.

Penrose is groovy! His drawings remind me of Codex Seraphinianus.

Global warming every day

Please could someone indicates me some papers to read about this theory of sir Penrose? thanks
-
"The mystery is, why was it that everything was high entropy... except gravity?" Doesn't it make sense according to General Relativity where gravity is a geometric phenomenon of space/time warping due to mass and not a force per se?
-
Uses advanced mathematical analysis to part the veil of eternity, peering back through the big bang for the first time, to demonstrate the death echo of previous universes *Can't work his computer*
-
What is the date this lecture was given?
-
How can such a brilliant thinker be so CRAP with a simple thing like a computer presentation?
