That is not to say it can be fully understood; but we understand enough to begin to master it ourselves while appreciating the transcendent nature of the Creator of all this, including us who are able to contemplate it. The four forces of the universe are most likely just that - four distinct forces governing key aspects of the universe with no mandate that they be unified, no more than the condition of the earth requires that it be millions of years old simply because radio isotopes have a forward decay rate in the millions of years. Some questions do have a 'no' answer! The models for determining the age of the earth are rough and even deficient in their assumptions, as are the attempts to unify the forces of nature into a Babel-like conglomeration.markgoghttp://www.blogger.com/profile/08333977749744575626noreply@blogger.comtag:blogger.com,1999:blog-35187314.post-29797951443958668322015-08-31T10:38:42.216-04:002015-08-31T10:38:42.216-04:00Let me "Phil" you in a bit.....

Pattern and information <br />denote an intelligence. The universe was designed, as was our inner desire to <br />have understanding and connection beyond ourselves. <br /><br />Assuming there is no God is a brazen act of stupidity since the evidence points to a designer.<br /><br />Hawking's claim that objective reality doers not exist, only relative observation points that <br />work for each individual, is sick and untrue. There is no theory of everything because the <br />foundations of physical reality are the four forces: gravity, strong/weak nuclear forces, <br />electromagnetism, the four pillars spoken of in the Book of Enoch (pre-flood Gospel for you neophytes of reality).<br /><br /><br />Euler's identity is a concise formula for the reality of our universe, which God gives as a clue to the link between faith and reason:<br /><br />e^(i*pi) + 1 = 0 where <br /><br />all mathematical operations are present,<br />growth is mediated by faith (imaginary number) and pi, the ordering of point and boundary, attraction and motion.<br /><br />God is represented by the 1, unity perfection, completeness.<br />our universe is the -1, made from nothing (that is, made from the very substance of Who God is) <br />and we have our being only in relation to the 1. The 1 did not need us to be 1; it was and always <br />will be perfect and complete. The 1 chose to make the -1 as a reflection of itself, out of love <br />and to expand the experience of love, simply for the sake of love. The 1 and the -1 can create <br />a new unity of being only if the -1 remains in balance, which this universe has fallen from through man's transgression of out will (sin). God is unremittingly pure and perfectly loving, wanting none of us to be lost when the universe is remade after transgression and death have been vanquished.markgoghttp://www.blogger.com/profile/08333977749744575626noreply@blogger.comtag:blogger.com,1999:blog-35187314.post-36488252514901586172015-05-10T14:11:24.820-04:002015-05-10T14:11:24.820-04:00For what it is worth, I have apparently solved the...For what it is worth, I have apparently solved the so-called "theory of everything".<br /><br />It is very simple but the math-related to it is fantastic and possible use of this I am looking for sponsors/ commercial application. <br />I can say that physics is "theory of every thing" = logic = objectivity.<br />All those different ways etc. re: not counting (of conserving time and space) yet what are they not counting?

How does the massive object cause spacetime to warp? To warp it it needs to be made of something right? But what? Can you warp nothing? Can something exist yet be composed of nothing? Or do we have to accept spacetime as some kind of 'magical substance, like the 'ether' (accepting that all the proposed fundamental particles are effectively 'magical' at this point in time)? Without the proposed graviton its kinda axiomatic and that is where some people may intuitively have problems with it, reject it as 'non scientific and thus requiring a different model to understand it. In some senses, this is where we as humans struggle - if a model predicts future observations reliably but seems absurd to many people, will it ever be accepted as the model? Will they stop seeking alternative ones that they hope make more sense? What if two models predict things equally nicely - which do we choose? Arguably we don't need one of them but which one? Either? What if one model seemed bizarrely different in nature to many other models we had come to accept for other physical phenomenon (strong, weak, electromagnetism) yet there was one that was pleasurably similar and evocatively symmetrical - which would we choose? Its a dilemma I grant you and one we haven't yet all agreed on I think.

Its rarely interesting when someone gets up and says "we don't know". I guess in this case its only 'kinda interesting' that he's (Hawking at least) said "I don't know if we will" purely because he is backtracking on a previous claim he made where he said "we will know ( ie discover this theory of everything)". All he's doing is claiming he now believes he was wrong and he's correcting that. An honourable admission no doubt but it hardly fills you with confidence in the event you might be considering reading his earlier works.Richard Smarthttp://www.blogger.com/profile/14716386216210405161noreply@blogger.comtag:blogger.com,1999:blog-35187314.post-7824244475592671272014-05-16T16:07:12.730-04:002014-05-16T16:07:12.730-04:00You were obviously having some fun there.

I don't believe in 0 or infinity, in the sense that neither actually 'exist' in reality (kinda to the point I think Hawking and Mlodinov were talking to I think so I guess I will necessarily disagree with you given that your theory seems to rely on them existing. I like to think of time as 'just another spatial dimension' but somehow under-developed or with the something squiffy about it I just can't put my finger on. It might have something to do with the fact that our understanding of anything (our 'models of reality') is inherently reliant on electromagnetism and of course electromagnetism has a relationship with the time dimension that differs from its relationship with the spatial dimensions. Regrettably we're talking about concepts that will not help us pass any 'soon to be useful' exams nor propose any 'soon to be useful' theories which is kinda why we probably have to end it here!Richard Smarthttp://www.blogger.com/profile/14716386216210405161noreply@blogger.comtag:blogger.com,1999:blog-35187314.post-3211875185486779702014-05-02T10:48:38.651-04:002014-05-02T10:48:38.651-04:00Please check the math?

It's a theorem...albeit a rather simple one. Like any theorem, it's only true if the axioms upon which it's been based are true. These "axioms" are statements that you boldly assert. Mathematics says "if your axioms are a true statement of the system in which you're working - then the following theorems are true".<br /><br />In the case of basic arithmetic, we do rely on some axioms - they are called "Peano axioms" - and you can find an article about them on Wikipedia. There are nine of these axioms. If all nine axioms are a true statement of our universe - then 2+2=4 is not only true - but we can construct a bullet-proof proof that it's true.<br /><br />So - if 2+2=5 then one or more of those 9 peano axioms is also false. These axioms are pretty hard to deny. "Zero is a number", "x=x", "if x=y then y=x", "if x=y and y=z then x=z"....and so forth. If you can deny that one of those axioms is true in some system in which you're working - then indeed 2+2 doesn't equal 4.<br /><br />Want an example? When I buy my wife a birthday present, a ring worth $100 is a better gift than a check for $100. In this gifting system, x doesn't necessarily equal x. It's no surprise then that giving her two gifts each worth $200 is not as good as giving her one gift worth $400. In this "wife birthday gifting" system, the ordinary arithmetic facts are inapplicable.<br /><br />That's not because math is 'broken' - or because 2+2 really doesn't equal 4 - it's not even because mathematics doesn't work in the realms of my wife's birthday preferences. It's because we tried to use a theorem (2+2=4) that's predicated on the truth of the peano axioms in a "system" where the peano axioms clearly aren't true because two gifts, each worth $100 are not worth the same thing. If x doesn't equal x then who knows what 2+2 equals?!<br /><br />However, these nine peano axioms are so obviously true for most things in our universe that we tend to forget to say "2+2=4 *if* there exists the number zero and *if* x=x and *if* x=y implies that y=x and....yadda yadda yadda". But in situations where that isn't the case, you have to come up with new axioms and set about proving new theorems. In the 'birthday gifting' universe, there are new mathematical statements to be made - but if you can come up with a solid set of axioms, you can use mathematics even in the weird world of gift-giving where 2+2 seems to equal somewhere between 2.5 and 3!<br />Steve Bakerhttp://www.blogger.com/profile/18284918588766160601noreply@blogger.comtag:blogger.com,1999:blog-35187314.post-51604135604765011612014-05-02T10:19:39.802-04:002014-05-02T10:19:39.802-04:00That's a common misunderstanding. Godel's...That's a common misunderstanding. Godel's theorem puts limits on what math can prove - it doesn't say that math is incorrect. In a nutshell, it says that there are statements you can make in mathematics that can neither be proved nor disproved. That doesn't mean that you can't know whether 2+3=5 or whether pythagoras' theorem is true or not. It means that there are some things that mathematics can't either prove or disprove. There are still MANY things that math can prove - conclusively.<br /><br />Maths works because all of the statements it makes are logically derived from a set of assumptions called "axioms". 2+3=5 depends on a handful of axioms such as "there exists a number called zero" and "every number has a unique successor"...2+3=5 is only a true statement about our universe if those axioms are true for our universe. However, the statement "If those axioms are true then 2+3=5 is also true" is a universal truth.<br /><br />Pythagoras' theorem is a great example of that. It depends on Euclidean geometry - which in turn depends on a few basic axioms, that there are straight lines, that parallel lines don't ever meet and so forth. One of those axioms basically says that the place where you're using these theorems has to be flat. If you draw a huge right triangle on the surface of the earth then the square on the hypotenuse most certainly DOES NOT equal the sum of the squares on the other two sides.<br /><br />That's not because dear old Pythagoras was wrong - it's because you tried to apply his theorem in a situation where the axioms on which it's based are not true. Euclidean geometry simply doesn't apply on the surface of a sphere.<br /><br />So what you need to understand is that Mathematics is "true" so long as you follow the axioms you set out for the statements you are making.<br /><br />Godel merely puts limits on what mathematics may hypothetically prove...it doesn't mean that math can't prove anything at all - and it certainly doesn't mean that you can' prove math mathematically - in fact one of the breakthroughs that Godel made in formulating his theorem was a way to use math to speak about mathematics itself.<br />Steve Bakerhttp://www.blogger.com/profile/18284918588766160601noreply@blogger.comtag:blogger.com,1999:blog-35187314.post-53945262023403416552014-05-02T09:55:13.631-04:002014-05-02T09:55:13.631-04:00Science works by "making stuff up" and t...Science works by "making stuff up" and then testing it against reality to see if it works. At one point, the Higgs Boson was "made up" - a hypothesis to explain the concept of mass...then we made the Large Hadron Collider to test whether that hypothesis is correct - and guess what? We found actual Higgs Bosons.<br /><br />Sometimes the stuff we make up turns out to be real - other times it doesn't. The cycle of hypothesis ("making stuff up") and experiment ("seeing if it's real") continues with the things that do turn out to be real becoming part of our understanding of the laws governing the universe - and the things that don't pan out leading us to the interesting question of what *is* real if it isn't that.<br /><br />Incidentally, there are plenty of efforts to formulate physics without time...that's another "making stuff up" activity that may or may not produce results in the future (er...well, not "future" if time isn't real of course!)<br /><br />Clearing of cobwebs is what science is all about - finding that some old stuff isn't right is always an exciting and interesting thing - and that's what scientists seek.<br /><br />The idea that you can't have a theory of everything without observing everything is kinda silly. I can have a theory that ducks lay eggs without seeing every single duck...I see a bunch of ducks that lay eggs - I make a theory. I find a male duck that doesn't lay eggs and I refine that theory. If someday we find a duck that bears live chicks...then we'll have a new theory. At each point, the theory we have fits the facts that we know.<br /><br />The problem with physics and the theory of everything is that we don't even have a theory that explains everything we CAN see. If we had such a theory that could explain everything we can see - then that would be a massive leap forward. That's not to say that we wouldn't have to modify it in the future in light of further observations.<br /><br />Newton's laws of motion were a correct description of the phenomena that people could see in the 1700's and 1800's. Einstein "made stuff up" to postulate that there were phenomena happening at high velocities - nobody was sure he was correct until a bunch of guys hauled telescopes to the far reaches of the Earth to measure the deflection of a star during an eclipse. When that showed that Einstein's "made up stuff" was better than what we thought we knew - we tossed out Newton and crowned Einstein as the new "best-description-we-have". I don't doubt that we'll eventually prove Einstein to be incorrect - but that won't happen until we find new stuff that we haven't seen before. But that 'stuff' isn't just lying around waiting to be observed...we need folks like Hawkins to "make stuff up" - then have people with big telescopes point them at black holes - or measure the speed that galaxies are rotating to find that "dark matter" or "evaporating black hole" or whatever it is.<br /><br />It's not a flaw in the system - it's how progress is made - and this "Scientific method" approach has served us amazingly well.<br /><br />Steve Bakerhttp://www.blogger.com/profile/18284918588766160601noreply@blogger.comtag:blogger.com,1999:blog-35187314.post-32180715427010227062014-04-11T16:32:26.672-04:002014-04-11T16:32:26.672-04:00I'm a scientist, and the same thing bothers me...I'm a scientist, and the same thing bothers me. If according to the block universe, Minowski space-time, Einstein's relativity, what-have-you, then you, anonymous poster, are right. Because if discoveries in science, paradigm shifts, the inventing of new technologies, and other forms of advancement in our knowledge occur in specific times along the time dimension, then NOTHING is going on. Absolutely nothing is happening. And perhaps that is the reality of reality: That no matter what you think about reality, the truth is that NOTHING is occurring, NOTHING is changing, EVERYTHING is an illusion yet at the same time Truth. So, there is this illusory paradox that makes everything problematic.<br /><br />This is why I think we need to figure out the scientific basis of consciousness rather than saying that an increase in dopamine equals happiness. That works from an outside observer objective, but it doesn't work well to explain reality.<br /><br />Yes, anonymous poster, there is a serious problem: I believe the physicists have recognized this.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-35187314.post-761013877228196602013-07-19T17:08:03.349-04:002013-07-19T17:08:03.349-04:00So basically we're back to the old "nothi...So basically we're back to the old "nothing left to discover" bit.

If you compare the number of years a person lives,lets say 100 to keep it simple, and compare that lifetimne to the number of years contained in forever... that is to say ALL existence you get... <br /><br /> 100<br /> ---- = 0<br />infinity<br /><br />This is assuming that while time in this universe may have started with Big Bang as stated above this is only one of the neighborhoods in the "multiverse". (Is that still the theory? I a not a PhD in physics ). And as subjectively all we know of is existence... there is no proof that there has ever been non-existence is there? Anyway the equation above proves that if I live to be 100 I will still never have existed. However...<br /><br />If you take the number of years contained in forever and compare it to the number of years a person lives, you get the equation...<br /><br /> infinity<br /> ---- = infinity<br /> 0<br /><br />I live forever... So since both can not be true and I am here writing this the second must be correct. My life is infinite.<br /><br />Please check the math.... thanks.<br /><br />Paulwhateverhttp://www.blogger.com/profile/12766687536152249704noreply@blogger.com
