Seeing Through the Big Bang into Another World - Professor Sir Roger Penrose
About | Information | History | Online | Facts | Discovery
The Annual Lewis Elton Lecture - 2012 According to currently standard cosmology, the universe started with a Big Bang, immediately followed by a fleeting moment of exponential expansion, called "inflation". Following this it settled down to a more sedate expansion, but due to what is called "dark energy", it is currently commencing a second period of exponential expansion that is expected to continue indefinitely. In this talk I describe an alternative idea, which argues that this picture provides merely one aeon of a continual succession of such aeons. The Universe never collapses in this model, but the remote future of each aeon becomes, when infinitely scaled down, the big bang of the next. Collisions between supermassive black holes in the aeon previous to ours would, according to my model, provide disturbances that should be just about observable in the cosmic microwave background of our own aeon. In this talk I shall describe evidence indicating that these disturbances may actually be present, and possibly providing us with some hint of what the aeon prior to ours may actually have been like. The talk will be largely free of equations, depending mostly on pictures, but a brief summary of the equations needed for the theory will be provided at the end. Brief biography: Sir Roger Penrose OM FRS is an English mathematical physicist and Emeritus Rouse Ball Professor of Mathematics at the Mathematical Institute, University of Oxford. He has received a number of prizes and awards, including the 1988 Wolf Prize for physics which he shared with Stephen Hawking for their contribution to our understanding of the universe. He is renowned for his contributions to general relativity and cosmology. He is also a recreational mathematician and philosopher.

Good choice of pen, Professor.

Einstein once said that if you can't explain your ideas to a sixth grader, then you yourself don't understand it. I so agree. Penrose, unlike so many scientists today, presumes nothing and has sacrificed his ego for the pursuit of truth which, BTW, he can explain to a sixth grader. Good job Roger!

Time is the answer . What we believe is the passage of time might not exist
-
I'd like to see what happened to this work.

Penrose is such a gifted lecturer.

Very nice presentation, especially for the layman's point of view, fairly easy to follow. No arrogance whatsoever as shown by many astrophysicists, cosmologists and theoretical physicists; on the contrary, modesty and sometimes hesitation characterizes his style that is justifiable for the subject with so much unknown phenomena .
What I get from his talks is that the Universe is not only infinite but has always existed and will never end and that must be true based on the laws of conservation of matter and energy. Matter cannot be created from nothing and cannot be destroyed, so the Universe could not have started out of nothing.
Also, apart from this talk, common sense tells me that space is self evident and infinite regardless of the amount of matter in it. So how can space and time be created supposedly at the "Big Bang"? Is it not a crazy idea?
I hope more scientists will join Professor Penrose to create a theory that explains the universe based on real physics and less speculation, without crazy ideas and more common sense. And if we cannot come up with what banged, why it banged and where it banged we should accept that we have finite knowledge and understanding. -
what if the universe perceives time differently than we do
-
Those arrows are really sexy.
-
The sequence of events since the big bang or even before has a sense of simultaneity, that says, nothing is happening-!!!
-
Why did you put so much distortion on the voice?
-
Photons have zero-rest-mass only in the model, but in reality photons also have the 'hooks' for forming particles (such as electron-positron pairs) and so there is in essence a statistically-nonzero-probability of photons meeting and 'hooking'-up, at least temporarily, in some pseudo-particle sense...maybe there are ultra-low-energy-particles we'd never notice compared to 'ours'....

WOW! this guy really believes in teaching through pictures not by deriving bundles of large equations. i like this. derivations can be found in any good book,but why we need a physics teacher is to explain the significance of these equations ,and how they are helping us to justify the physical picture. the way dr. penrose lectures is profound, liberates brain to think beyond boundaries. feeding just equations don't do that.

There never was a big bang. The big bang is just one more belief of those who believe in the god of aeons of time.

Nuclear Force Energy Theory Matter is held together by Nuclear Force Energy: Atoms by Nuclear Force Energy of 2 Electrons/protons by N.F.E. of 4 Bosons/mesons by N.F.E. of 8 Quarks/anti quarks by N.F.E. of 16 X particles (the force of gravity) by N.F.E. of 32 At the moment of the Big Bang, All the Nuclear Force Energies were released from matter at once! And interspersed into space as the early Universe Expanded! They All remained Separate Energies in the Hot Broth of the early Universe!

Why are we here and where did we come from, Stephen Hawking asks? This subject, Nuclear Force Energy theory, may be a good one for Undergraduate Students!

Nuclear Force Energy Theory continued After the Big Bang as the Nuclear Force Energies cooled the Nuclear Force Energies began to coalesce into Matter! Starting with the highest: N.F.E. of 32 into X particles (the force of gravity). Then N.F.E. of 16 into quarks/anti quarks. Then N.F.E. of 8 into bosons/mesons. Then N.F.E. of 4 into electrons/protons. Then N.F.E. of 2 into atoms. Then into all the Matter we see today! 118 or so Elements!

He's a great teacher, in my opinion. His method and style are very accessible for a student.
