I have alot of scientific knowledge. He took for ever going through general relativity and quantum mechanics. He didn't tell me anything that I already didn't know. He also said that string theory at the moment is not provable and the same is true for loop quantum gravity. The thing with string theory is that you in science can sometimes use mathematics to prove something that is not possible with the current technology at the time. The atom was coined by some of The Greek Philosopher's 2 and a half thousand years before it was discovered. There is more mathematical evidence for String Theory then there is Loop Quantum Gravity. That being said a TOE, there will probably be a valid scientific esoteric theory in the future in which the TOE will be discovered with regards to gravity, relativity and quantum mechanics will be something else entirely.

No whatsoever - dynamics without "Space". Never a question what keeps it together, rather what keeps it apart.
The highest potential is 0, vibrating with only one physical property, resonance. No explosion at the beginning
and no drama at the end. It all happens here and now, with all those "dark" forces involved - Shiva is dancing destroying
and creating space in the smallest possible place. A Photon and a "Black Hole" having the same nature, they are
Plasmoids - Matter is electro - cymatics, synchronised, harmonic, beautiful and Sound/Resonance the most neglected
force. .......OM

"South pointing Chariot example". First this is nonsense. As he moves from the pole to the equator the vector would be pointing straight up. But let's say he has a compass. He gets to the equator and then moves to the east. The compass still points to the South. He gets almost to the pole and the compass still points to the South... but 90° from where he pointed initially. now at that point he moves around the circle to the West...maybe one step. The compass still points to the South. But when in line with his initial path it points in the same direction as initially. From there he can take the one step to the pole and he's back where he came from...and the Chariot pointer points exactly the same way. Actually when he's at the pole, even from the beginning, the South pointing vector could be going in any direction. All directions are South.

@FlatFact i meant quantum mechanics which is the basis for modern electronics and indeed the internet as a whole, most of which does not use the radio spectrum but are optical lasers.
FlatFact - 26 dias atrás
@Sudazima No I don't think you are right. Electricity and the communications by radio waves [which is how the internet works. All electronic communication uses a frequency in the radio spectrum, including GPS] Were invented some 150 years ago. By creative humans and has been developed ever since, and is supposed to be for the benefit of us. Space is only the final frontier of one's imagination.

I've watched RI lectures since I can't remember (I'm 64). Jim carefully talked his presentation through in such a way that I heard and could digest every word. Perhaps the sound effects weren't necessary, but otherwise he managed to avoid any other dramatic concessions. For an interested layman, I've never seen a better lecture on this or any other subject. Thank you.

Surely interesting, yet time as a human construct with set instruments like moon sun and earth are never able to be constant - UNLESS - you keep it constant. Sure space can be seen or made visible...on earth add smoke...than see this smoke dissolve in oxygen and fuse with it. Sure light speed is a constant when you keep it constant. Question is more can we, and can we manipulate it to serve us.
All can be made to. We are generally seen... nonlogical beings looking for logics and systems within our environment in order to find a general use with it,, but measures can be made constant or made dependable upon and vary with. It is how you wish to measure it. Time is non existing. While space and matter are. So why add a human fantasy, within these theories? I cannot find any logic for doing so. Feel free to start counting YOUR way! My question is time existing or did we create an understanding about time and how to calculate it.
Second question is if light can be waves or particles as in photons, than is light in waves and photons in particles taken as the same, or are they the same, or do we observe them as being light. Sure light waves differ, do photons differ in the same way,...? I dare to say that we observe them possibly as being the same result - being light. Yet they are two complete different ways to a same outcome therefor it is impractically and impossible for them to be the same. When bound by general acceptations on all these, we will never find the answer, when it sit's outside our box. So I dare everyone to think differently, and stop politically and insanely put science up for debate, yet taking the proven facts outof it as a generality to calculate on. Feel free to take your time, since it does not exist to begin with.
Than the silly though of holes in space we call black holes. I can imagine tunnels or formation of gaps in space or masses, yet holes. To me black holes are no holes at all but spherical masses that form such strong gravitation outof which light in every of it's existence cannot escape. In other words combining it all into saying it is engines of gravitational origin. The magnet magnetizing metal...the binding force of matter drawing in or pushing out mass. Now for it's calculation. Preserved for a next moment. If some black holes dissolve anything around them, than where does all the matter go...into a hole or into a tunnel? Or does it form a spherical formation and when swallowing matter etc...grow larger or in cases of push and pull circumstances where does this matter stay, does it become part and grow the gravitational strenght of the sphere or form a larger hole? This is why I state, black holes or no holes. I am sure there is tunnels of non gravity between the forces we shortly called black matter.
There is already evidences of black holes having gravitational fields and some spit out matter, or gasses or even new suns,...in which it is taken as the birthplace and origins of suns. I would not take them up for generalising them. Generality does not exist to me either. Succes factors and commonality do. I guess it is time to find this all out soon, since our succes factors here on earth are rapidly decreasing. Ever the more becoming dependant on our combined luck to survive, I think it is about time we stop using money, we stop using fantasies, but suit them to a right place in existence or non existence. Time is ever changing and exists different anywhere we would calculate it with an ever changing index we find in Earth, time is of no value to these calculations. Can only be interpreted within these calculations when needing to find out for instance if we aged. Since we know we do, there will be never a moment when we become babies instead of old humans.
Luck wise this is non of my concern it is only a concern to me as part of a species that need to survive. As long as we claim individuality and hierarchy we will not seriously evolve into a species that maintains it's survivability. Needing to put our personal names under findings instead of our species, is the issue at stake. We need to learn to think as species, not as individuals. I am quite sure, than when we do, we will evolve beyond what we now take as time or end of time. Nothing on that stake matters, when non existing.

I'm not expert on this and don't know how the super computer works mathematically but didn't we quantize the space ourselves when we put the gluons and quarks on a lattice for lattice quantum chromodynamics which could give the appearance of quantified space?

One final problem to think about, he states that there is no such thing as infinity in nature. How would we prove or disprove infinity exists? It seems to show up in equations as singularities, which we dismiss as quirks of the science. Well, if we accept infinity in the equations then we must accept it exists in nature. What does this imply for things like the nature of space (infinite?), the nature of time (either zero or infinite in length?). I think these are hard problems often shrugged off as minor details.

Two more things that are highly troubling, the problem of frozen time (the implication that time is basically not flowing in the universe, but locally fluctuating) and that entropy is proportional to area of black hole (that all the information is contained in 2 dimensions). We are just getting started.

Philosophy not physics. Compare and contrast the early history of quantum theory to quantum gravity: first Planck in 1900 and then Einstein in 1905, then Bohr in 1913, then a flood of explanations of hitherto unexplained phenomena. Then, some 60-70 years after Planck the first observations of quanta.  
Quantum gravity research is driven solely by the mathematical desire to unite two disparate theories with no empirical evidence. There are no phenomena that quantum gravity research is trying to explain save the structure of the universe. With multiverse theory they've bailed on even that. It is unknown even if the universe contains enough energy to observe a solitary graviton. It might be reasonable for a few people [Witten, Polchinski (RIP), Susskind, Smolin, a few others] , to be working in this area, but IMHO the thousands working in quantum gravity are wasting their intellect.
I read a quotation from University of Texas @ Austin physicist Len Klein the other day that seems appropriate to close with: "when theoretical physicists have no data they hallucinate."

Because we live in a gravity well, our time is slower than time outside of a gravity well, deep in space, nearly devoid of gravity. So it is tricky to understand how old the universe is.

He says "there are no infinities in nature." Then he says "maybe the universe began with a bounce rather than a bang."
Pardon me if I am missing something, but the bouncing universe cosmology implies an infinity of Time... right?
sinephase - 14 dias atrás
if time is a consequence of inflation, then the start of the "bounce" is without time, and time starts again in the next cycle. It could be an infinite cycle but I don't think that's the kind of infinity he's talking about.

It implies that time isnt even in the equation. "Frozen time issues" basically space with out mass outside of quantum would be so small in distance time is irrelevant. And its sort of an oxymoron like the quotes at the end implies.

Gee whizz, we Hindus worked this out many millennia ago. Of course, we being heathens (and im soooooo glad for this) the super intelligent part of homo sapien sapiens loosely termed "western civilization", find it best to treat us with derision & contempt. Unless they are forced to assign any of our accomplishments to their fellow barbarians, the arabs. Go forth, however, but it is unlikely that you will discover a charming little fable I learnt at my grand mother's knee as a 7-8 year old that tells of what you speak.

Quantum- a word used by scientists to describe non-scientific guesswork.
There is such a thing as absolute time, it's calculations solve for movement. Just because you perceived it different doesn't mean it's correct.

The time particle is infinitely smaller than a planck length. But then again the singularity would be. It is naked. It is in effect and affect everywhere at once. And is faster than anything else including the speed of light as it has no mass. There is only one. Time is not linear. Linear time is a learned concept extremely important for increasing our survival optimum.
