@@tyreza79 blasphemy? you are still living in mediaeval era. There is no place for such Stone age thinking and mentality in 21st century. God is not what you think or what you bealive. By saying things like "veil on true light of God" you are reducing god to just a weak entity who gets affected by deeds of humans. No it won't get affected. If it is all knowing all powerful,and present everywhere how can you call it as weak entity? Isn't this is sacrilege and blasphemy rolled into one? Acording to standard of mediaeval era thinking? Iam not saying god is not real. Iam saying you are misunderstanding the definition of God. There is no such thing as "personal god" god is not what you think or like to bealive. Can someone living in light or fire differentiate between dark and moonlight? Light is shadow of God. Darkness is just absence of this shadow.

As i understand it, the graphs are built on the principle of conservation of spin. Size of lump here just correspond to the section of the lightcone 14:00 The boundary qft can be replaced by the deterministic de Broglie double solution theory (DST). I speculate, that DST=GR (ADM formulation) I'm very much convinced, that boundary correlations can propagate as fast as you wish(several light cones in parallel). See papers by Gonzalez-Mestres. There's some fractal structure down there, beyond the uncertainty principle, in deterministic theory. Probably, self-similarity, even. As much as I like the bootstrap program, i understand it still gives the approximate description of nature. It is unable to explain the speed of light. However, we know it is perfectly possible to calculate the speed of sound in a medium.

Such symmetry is sufficient to describe location all the points in the space. Symmetry of time is one dimensional- defining one time parameter is sufficient to locate the event in time. What is the physical purpose and sense to combine boths entities, with different symmetry? 2- Just on the begining during Big Bang all the energy and mass was collected together and it had not collapsed into one big black hole - only expanded violently and turbulently . Can we assume , that in this time the mass and gravitation was not present yet there and that the massive particles were condensed later on? 3- Has the physical Space any cohesion, which would bring the Space together to Big Collapse after all particulate matter will be swallowed by the black holes? 4-If so, it is possible, that our Space is oscillating in time interval 33 billions of years per cycle - in the space of diameter 0-120 billions of light years.

I guess my question is that I don't seem to understand if 'particles' are real entities in themselves or 'emergent' parts of something deeper.

@@nmarbletoe8210 Yeah, we're in a highly speculative area when we're talking about that final stage of the evaporation. Increasingly higher energy/ momentum particles will be emitted and the whole process will be , presumably , chaotic: The tiny evaporating black hole will bump like in Brownian motion and we cannot be sure that it will be still a " black hole" with a smooth trapping horizon ( there are obvious issues with spherical symmetry/ the " hoop conjecture"). Nobody knows if Penrose's " Cosmic censorship " will still hold in such extreme situation. The question is about the uncertainty principle ( or some modified version of it): Is a relation between "momentum and position uncertainty" really a fundamental obstacle ( *) for probing very small distances at the end, if nothing remains but smooth empty spacetime? I don't think that our current knowledge permits us to have some definitive opinion about this, but others may know more..

It seems like that would make it even more difficult and abstract. How much is lost in translation? The transcript may help, and it could be translated into various languages. Even so, like a permutation or something, when you take the word butterfly and you say it in various languages, even though you may understand the various ways of saying butterfly and what insect it identifies, each language label is unique and elicits a different response. For example, I may know butterfly is also mariposa in Spanish or forashay in Arabic, etc. the word that FEELS the best in that case (for me) is forashay. You may never get the feeling even if you get the word or translation. Some words are just better in certain languages. Nuances can also be lost in translation. Maybe the international language should be an international sign language. We could hand jive our way through it, maybe add a little shimmy for extra pluck, or Planck, or juxtpa, or whatever that is...square that energy and do a square dance and you get the idea. In the above video the physicist started theorizing about the end of Space-Time and spoke of all of the action being along the walls. I think of the wall as taking up space as well, and it does, leaving us back with space and anything happening on the wall is happening in time, so we are back to the Space-Time continuum, even if you are just a wallflower. If you want to get beyond the Space-Time continuum meet me at my house at 11:00.

@ Siva Kawachine Why would anyone want to eliminate ANY language - I am flabbergasted by the NOTION of your comment "less is better for for 'efficiency reasons' as you were alluding rightly so before to the fact that each expression has its own "beauty". I would call it resonance based on my understanding of THE BIG SHOW humans are part of.

Flawed logic. Everyone will imagine the very same word differently unless you define it in a very precise way, you do not need a different language for that. Say rabbit, now our two rabbits are different and the Spanish one is different to the same degree as our two English ones . . unless we define the rabbit in a way that there exists only a single way that it can be imagined. It is like saying that a loaf of bread will be the same as long as we use the same oven, but the question of oven is just a superficial layer that can be solved easily as long as you solve the deeper issue.

@@ACuriousChild I don't want to eliminate language at all, I was merely offering an international sign language as a more universal way for people of all nations to communicate. I like languages. If I said less is better, then proceeded to write what I wrote I wasn't following my own advice. It wasn't concise at all. I think your comment is well written and I am having no problem wrapping my head around it. It's nice to see the level of intelligence I'm noticing on this thread, I am humbled.

@@slingshotchicken4695 Don't remember my exact words but deducing from your frank and honest response I assume my wording was harsh nevertheless honest and based on "pure heart". Implying intentions based on fellow HUMAN MINDS expressions is mainly a way of pointing out the blind spots - one's own and everyone's else's . No-one (apart from HUMAN MINDS with a dark agenda, usually hidden from their consciousness) would ask to eliminate plurality or diversity (not the politically motivated one - which is a BIG LIE anyway) of any expression. HUMAN MINDS like yours are surely the future - notwithstanding any differences of perception.

@@emilnemyl448 I'm having a little trouble absorbing your reply, I will have to read it a few times, it's pretty cerebral. OK, I'm getting the first part now. No, you don't need a different language for that, but a different language just adds more (at least for me) . I can look at a table and use the word table and experience it slightly differently than if I'm thinking of it, while looking at it, using the Spanish word "mesa." Mesa allows me to see the tabletop as more of the top of a flat tall mountain, whereas when I use the word table, I don't get that vision, I just see furniture. I'm not even experiencing the object in the same way when I identify the object in these various languages. Yes, everyone will experience it, even in one language, uniquely. This is a very unusual exchange. It's as if people on this thread are able to utilize their minds in far higher and more creative ways than the usual Yahoo comments section, it's awesome but challenging to keep up. I really appreciate how expansive the thinking is on this thread.

The end of space portion of space-time, as the basic phenomena it is thought of, is not an emergent property which is still with us, yes quite plausible, but not the time portion! Time is the register of events, nothing is more basic than this!

so Leibniz was right about space and time?

Time is only defined as when points in space are moving and changes position. Every single point has it own time. The time we see may be called "statistical" time. Many points together makes your reality.

I wonder what the implications of "the end of space time" are. It would seem like many assumptions about the universe being "all there is" would dissolve. If things aren't really concrete maby it's more about us being able to percept them? Because it's not like a clockwork ticking it's more like a stage of interactions. Maby that put's in to question the more materialistic interpretations of the world? If phenomena emerges maby the point is that there needs to be a perceiver? I'm just pondering.
