"Before the Big Bang?" (2005), the original lecture by Roger Penrose (part 4 of 9)

"Before the Big Bang? A new perspective on the Weyl curvature hypothesis"

This is the original lecture by Roger Penrose on his fascinating new model of the universe, its origin and future, and of the "Big Bang"; held at the Isaac Newton Institute for Mathematical Sciences (November 7th 2005).

SUMMARY:

There is now a great deal of evidence confirming the existence of a very hot and dense early stage of the universe. Much of this data comes from a detailed study of the cosmic microwave background (CMB)—radiation from the early universe that was most recently measured by NASA's WMAP satellite. But the information presents new puzzles for scientists. One of the most blatant examples is an apparent paradox related to the second law of thermodynamics. Although some have argued that the hypothesis of inflationary cosmology solves some of the puzzles, profound issues remain. In this talk, Professor Penrose will describe a very different proposal, one that suggests a succession of universes prior to our own.

Sir Roger Penrose is a highly distinguished mathematician and theoretical physicist. He is currently emeritus Rouse Ball Professor of Mathematics at Oxford University. His research interests span many aspects of geometry, having made contributions to the theory of non-periodic tilings (Penrose tilings), to general relativity theory and quantum foundations. He has also had remarkable insights in the science of consciousness. His main research programme is to develop the theory of twistors, which he originated over 30 years ago as an attempt to unite Einstein's theory of general relativity with quantum mechanics.

In 1994 Professor Penrose was knighted by Queen Elizabeth II for his service to science. He has received numerous prizes and awards, including the 1988 Wolf Prize, which he shared with Stephen Hawking for their understanding of the universe, the Dannie Heinemann Prize, the Royal Society Royal Medal, the Dirac Medal and the Albert Einstein prize to name a few.

Penrose is a prominent lecturer and author. His 1989 book The Emperor's New Mind became a best seller and won the 1990 (now Rhone-Poulenc) Science Book Prize. His latest books are Shadows of the Mind (1994), The Nature of Space and Time (1996) with Stephen Hawking, The Large, the Small and the Human Mind (1997) and Road to Reality (2004).

Who is it that suggested that singularities ie black hole is actually converting matter,light etc. to dark matter and dark energy

[zanaelf]

There is more than universe and it is a quantum universe, and a section of the tesseractic fractal of infinity... it can not be created or destroyed only transferred.

And yet, we can see, we can visualize the ethereal matter. The scheme to one device for to visualize the ethereal matter: EXIST! And this device it can realize!

You Tube: sandustanBrasov’s Channel Dark energy is the ethereal energy and this can be harness it!

The matter of the our terrestrial globe has four states of aggregation: solid, liquid, gseous and ethereal and not three after official science. The matter on which we see it, proceed from the ethereal matter, which from cancentration in concentration it had constituted in the electrons, in protons respectivel;y in the atoms of the chemical elements which had overtaken at the gaseous, liquid and solid state. All the matter on which we see it, is condensed ether.

The GRAVITY’s PARTICLES as aproximately the smallest ethereal particles, constitute the most general ethereal aggregation state from nature, with the largest temperature interval, from zero Kelvin degrees to millions of degrees in stars. That is an aggregation state which coexist with all others aggregation states(solid, liquid, gaseous, ethereal) and on which it influenced them. The actual official science is mistaken in great proportion because this has not in sight the Ether.

The ACTUAL ELECTRICAL GENERATORS : galvanic elements and electrical accumulators; dynamos and alternators; thermoelements and photoelectric cell - transform nothing, but they only gather the electrical energy= the particles of the electrical ether which exist in metals, in the environing medium, in the thermic radiation or in the ray of light!

The ELECTRICAL CURRENT consist in circulation in the round and in lengthways to one electrical conductor to the particles of electrical ether guided on the magnetic field from the round the conductor; magnetic field formed all from particles of electrical ether coupled head at head and expelled in concentric circles in the round the conductor.If it interrupt the electrical current, then it decompose and this magnetic field in particles of electrical ether and it drain in circuit

The ELECTRICAL FIELD is a field of particles of electrical ether, free and it move approximate in right line.The MAGNETIC FIELD from the round of one conductor is constituted forever from particles of the electrical ether, but magnetic coupled head at head and it move on a curve forming concentric circles in round to one conductor.The ELECTROMAGNETIC FIELD is a combination of particles of electrical field anf of curls of magnetic field, having property of the evolve in space.
