Quantum Invariance theory aims to reconcile the incompatibility of quantum physics with general relativity and eliminates singularities. No extra dimensions are introduced beyond the ordinary four dimensions of space and time, except for in cases of constructing artificial models for the sake of visualizing topology.<br /><br /><span style="font-size: large;"><i><b>Overview</b></i></span><br /><br /> The starting point for Quantum Invariance theory is the idea that, in accordance with Quantum Mechanics, space and time must be quantized, and in accordance with Relativity theory, space and time must be joined together. Thus, according to QI, space and time are quantized together as inseparable units of 4-dimensional spacetime in the form of hypercubes 1 planck length in extent. Each hyper-voxel of spacetime is called a <u><b>hyperquantum</b></u>. In QI a three dimensional object does not exist as a distinct object in space alone, but must exist as a 4-dimensional object with extension through time. Thus a cube of 1 planck length is never just a cube, but instead the cube always exists as a 4-dimensional hypercube. No additional dimension is added, spacetime remains 4-dimensional, with each hypercube building up to form a hyperprism or elongated hypercube.<br /><i><b></b></i><br /><i><b></b></i><br /><i><b></b></i><br /><i><b></b></i><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/-GY7cwx-sKkk/VIrK8Gs59iI/AAAAAAAABa0/6tpKn1eLicE/s1600/8-cell.gif" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://3.bp.blogspot.com/-GY7cwx-sKkk/VIrK8Gs59iI/AAAAAAAABa0/6tpKn1eLicE/s1600/8-cell.gif" /></a></div><i><b></b></i><br /><div style="text-align: center;"><i>(A planck cube existing for one planck second appears as a hypercube.)</i></div><br /><i><b>Dimensional Closure</b></i><br /><br /> Quantum Invariance theory is also concerned with the largescale shape of spacetime. Each dimension of space or time are understood to be composed of perfectly straight lines extending in opposite directions for a non-finite distance, eventually meeting back to where they started without curving. These are known as <u><b>full dimensions</b></u> which are said to have <u><b>dimensional closure</b></u>. (Thus it might be helpful to think of QI as "Full-Dimensional Hyperquantum Invariance Theory). As a whole, each of the four dimensions form a hypercubic lattice which is topologically connected as a flat hypertorus. Because each dimension extends infinitely, eventually meeting back upon itself without curvature, no embedding of the hypertorus in a higher dimensional space is required for it to remain flat. <br /> However, when conceptually modeling the infinite structure of the entire Universe in a finite way as a "map" for the sake of study, the structure can be depicted as a repeated series of 8-dimensional orientable manifolds isomorphic to a Clifford torus. But it is emphasized that this embedding does not reflect the true nature of the actual structure of the Universe, it is merely used as a geometric model for the purpose of visualization. A more simple example of this principle would be to model a single full dimension as a circle in order to study its topology, so long as it is understood that the true dimension has no actual curvature and in reality cannot be shrunken down. In this type of artificial construction the quantum nature of spacetime is lost.<br /><div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/-wPHCu7X3GWE/VIrLl7IfrLI/AAAAAAAABa8/EJWzwJbPF2E/s1600/Clifford-torus.gif" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://2.bp.blogspot.com/-wPHCu7X3GWE/VIrLl7IfrLI/AAAAAAAABa8/EJWzwJbPF2E/s1600/Clifford-torus.gif" /></a></div><br /><br /><i>( We can think of this Clifford torus in 4-dimensional space as a representation of 2 ordinary spatial dimensions shrunk down and embedded in hyperspace, but in doing so we sacrifice the quantum nature of spacetime. )</i><br /><br /><i><b>Scale-Recursion</b></i><br /><br /> An interesting consequence of this kind of toroidal space is that, given enough time, any path in a straight line eventually returns to where it began. This is true of directional space, time, and even size, known as <u><b>scale-recursion</b></u>. Thus, if you were able to zoom in on something infinitely, zooming in on an object, you would eventually see outside of the object to the entirety of the Universe, zooming further you would see the object appearing much larger, and then zooming further, would take you back to where you began. Events in time happen only once, but because the time dimension is a flattened closed loop, all future events will eventually lead back to past events. (This effect can unexpectedly be found in some forms of string theory where the size of a string in relation to the Planck scale is equivalent to the inverse of its size. So that, for example, a string of the size 1/4 is the same as a string of size 4. On enormous scales this effect becomes unnoticeable.)<br /> It is worth pointing out that although space is quantized as a smallest unit in Quantum Invariance theory, it is meaningful to go lower than that size. The wording becomes confusing, but really what is happening is that a smallest size is understood to mean a smallest size before repeating what is equivalent to larger space. Anything below the planck scale is a repetition of larger sizes, accessed from the bottom down rather than from the bottom up. (It sounds strange at first, but it is not much different than distance on a sphere. Traveling a very short distance in one direction will take you to the same point as traveling a very long distance in the opposite direction.)<br /> The nature of time in Quantum Invariance Theory should not be confused with the nature of time in cyclic models. In some cyclic models, identical events recur over and over again, as local time is a finite closed loop in a greater time line. In QI time acts as a closed loop, but there is so much time that there is only enough time for each moment to occur once. So although time is connectedly cyclic, it is not recurring.<br /><br /><a href="http://4.bp.blogspot.com/-a6eiU0rlYxc/VIrMfzGF2bI/AAAAAAAABbE/YEklrCPQl5U/s1600/cubbe.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"></a><br /><i><b>Digital Geometry</b></i><br /><br /> In Quantum Invariance theory, the fact that spacetime is quantized results in a new form of geometry which does not strictly follow the familiar axioms of Euclidean geometry. In Euclidean geometry, two points are connected with a single unique line. In digital geometry more than one line is possible. In Euclidean geometry the parallel postulate states that one unique line can be drawn on a point which is parallel to another line. In digital geometry more than one line can be drawn through a point which is parallel to another line. <br /> Other Non-Euclidean consequences of QI arise from dimensions being fully extended to closure. For example, Euclid states that only a single line may be drawn to connect two points, but in QI a line may be drawn in the opposite direction which will meet the point from the other side, as well as many other complicated paths. Similar to spherical geometry, but without curvature. (In other words, in QI, transferring a geodesics into ordinary Euclidean space, it would have no curvature. Transferring a geodesic of a sphere would be curved in Euclidean space.) In Euclidean geometry, any straight line segment can be used as the radius of a constructed circle, in QI this is limited to lines which are half the length of a dimension or smaller. And lastly, Euclid's second postulate states that any straight line segment can be extended indefinitely in a straight line, while in QI, because of dimensional closure, a straight line segment can be extended only so far before it eventually meets back upon itself.<br /><br /><br /><div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: center;"><i><b><a href="http://4.bp.blogspot.com/-a6eiU0rlYxc/VIrMfzGF2bI/AAAAAAAABbE/YEklrCPQl5U/s1600/cubbe.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://4.bp.blogspot.com/-a6eiU0rlYxc/VIrMfzGF2bI/AAAAAAAABbE/YEklrCPQl5U/s1600/cubbe.jpg" /></a></b></i></div><br /><br /><div style="text-align: center;"><i>(Squares that appear distorted are not really distorted.)</i></div><div style="text-align: center;"><i><b> </b></i></div><br /><i><b>Invariance</b></i><br /><br /> In Quantum Invariance theory, the relativistic effects predicted by Einstein's theories of Relativity should remain the same, but there is a difference between observing apparent relativistic effects in space and understanding invariance of spacetime. An example is the turning of a cube. When you rotate a cube, the shape of the square faces appear to be distorted even though we know that the actual shapes always remain squares. In a shadow, it is true that the shape truly is distorted, but we understand that the shadow is not the thing. It is the same for invariance. We do experience relativistic effects in 3-dimensional space, but without understanding the full picture, we are confusing the shadow for the thing. An example of something that would appear distorted relativistically but not invariantly, would be time dilation and the relativity of simultaneity. In the grand scheme of 4-dimensional spacetime, there is no absolute space, and there is no absolute time, but there is absolute spacetime.<br /><br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/-ZiCNNxTNjaQ/VIrNqlZVquI/AAAAAAAABbM/-VYyMKvPV7w/s1600/cmb.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://3.bp.blogspot.com/-ZiCNNxTNjaQ/VIrNqlZVquI/AAAAAAAABbM/-VYyMKvPV7w/s1600/cmb.png" height="187" width="320" /></a></div><br /><i><b>Testable Predictions</b></i><br /><br /> One major prediction of Quantum Invariance theory is that the apparent age of the Universe does not represent the actual age of the Universe. (In QI, the Universe does not have an age at all. Only a non-finite time limit before any given point recurs.) The apparent effects of redshifted galaxies and cosmic-microwave background radiation and the supposed metric expansion of space are believed to be relativistic effects that become invariant in the full 4-dimensional view of spacetime. The apparent acceleration of expansion of space is predicted to appear the same in any region of space or time. If true, the apparent age of the Universe should remain the same in the future and it is predicted to have appeared the same age in the past. As methods of measuring the apparent age of the Universe improve with greater precision this will become increasingly easier to falsify or confirm.<br />Another testable prediction of Quantum Invariance theory is that events in the future must lead to events in the past. This puts a strict limit on what events are able to occur in the future without closing off the possibility of time returning to the current present state of the Universe. The Universe cannot spread out and freeze, for example, and never warm up again. Also, since time is quantized, assuming dimensional closure, the number of total possible Planck seconds must be a definite specific value. According to this specific value, only certain recurring patterns could occur because the amount of cycles must divide evenly into the amount of possible time intervals. For example, if a certain phenomenon was expected to periodically occur once every 10 planck seconds, but the total amount of Planck seconds in a full dimension of time was a power of 2, we would know that the phenomenon would have to change at some point in the future, or would have been different in the past.<br /> As instruments become more sensitive in future experiments, it may be possible to verify the cubic nature of hyperquanta. If shapes besides hypercubes are allowed, this will manifest as apparent changes in the speed of light, apparent changes in mass as particles travel through a square of space, then and octagon, then a square, etc. If space were triangular, we might expect polarity to shift as orientation of each consecutive triangle in a tiling shifts. In truth though, the only possible shape that will be the same everywhere is a hypercube. Anything that requires the structure of spacetime itself to drastically vary would require an explanation.<br /> Lastly, like all theories that involve the extremely small Planck scale, some aspects of Quantum Invariance theory may be very difficult to test. However, because of scale-recursion, where something incredibly small is also incredibly large, it may be possible to see the effects of the Planck scale by observing largescale structures of the Universe. Clues may lay hidden in the cosmic microwave background radiation, or in the detection of gravitational waves. Similarly, we may be able to obtain data about incredibly large timescales by observing incredibly small time scales, effectively observing the future.<br /><br /><br />AdamLorehttp://www.blogger.com/profile/05980568839722473163noreply@blogger.com0tag:blogger.com,1999:blog-101584470909732121.post-64821774275124596362014-12-09T22:18:00.001-08:002014-12-09T22:18:15.148-08:00Rick Rosner's theory of Informational Cosmology<b>Rick Rosner on the Big Bang Theory and Informational Cosmology</b><br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/-ASjWsZn8LwU/VIfiUuEYjvI/AAAAAAAABac/8akWYOiUM5Y/s1600/smartestman_240412_648x365_2226296978-hero.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://2.bp.blogspot.com/-ASjWsZn8LwU/VIfiUuEYjvI/AAAAAAAABac/8akWYOiUM5Y/s1600/smartestman_240412_648x365_2226296978-hero.jpg" height="225" width="400" /></a></div><br /><br /><br /><br />Excerpts form <i>In-Sight's</i> interview with Rick G.

If the universe undergoes repeated multi-billion-year unfoldings, there should be lots of stuff that’s older than the apparent 14-billion-year age of the universe. That stuff won’t necessarily be in our immediate neighborhood – we’re new – we came into being as part of the current unfolding.<br /> Via repeated cycles (not cycles of the entire universe expanding and contracting – not an oscillating universe – more like a rolling boil) of galaxies lighting up and burning out, the dark matter we’re looking for (to explain gravitational anomalies such as the outer rims of galaxies rotating faster than accounted for by the distribution of visible stars) might be a bunch of neutron stars and near-black holes. If anything could survive repeated cycles without being completely ablated away, it would be near-black holes. (Don’t really believe in fully black holes.) A universe which has gone through a zillion cycles might have generated a bunch of burned-out junk (or, in an informational sense, massive settled or solved (for the moment) equations or clumps of correlations or memories or independent processors whose operations the wider universe doesn’t much participate in/isn’t very conscious of) hanging around on the outskirts of galaxies.<br /> A brand-new universe – one that’s unfolded after a single big bang – doesn’t have much opportunity to form a bunch of collapsed matter. But a universe at a rolling boil – that is, a “continuing series of little bangs” universe – would generate lots of junk. It’s that house with all the trashed cars and plumbing fixtures scattered across the front yard.<br /> Just for fun, we could multiply the 14-billion-year apparent age of the universe by the 5 billion lifetime cycles of the human brain. There’s no reason to assume that the universe goes through 500,000 or 5 googol rolling cycles. But anyhow, 5 billion times the apparent age of the universe gives you 70,000,000,000,000,000,000 years. That’s based on not much. What if the expected duration of a self-contained system of information (in terms of rolling cycles) is proportional to the complexity of the system? What if the complexity, like the average distance from the origin of a random walk, is proportional to duration squared? The universe could be <em>really</em> old.<br /> No way the universe unfolds just once. No way it’s only 14 billion years old."<br /><br />(43.) <br /><br /><br />"In a Big Bang universe, we can see across nearly 14 billion light years. (Microwave background radiation has spent nearly the apparent lifetime of the universe reaching us.) But we’re not looking at a sphere 14 billion light years in radius, because the background radiation comes from a very small, young, recently exploded universe. (There’s a maximum radius we can see as we look across greater distances and farther into the past. Beyond that radius, we’re seeing increasingly smeared-out images of our universe when it was younger and smaller. Of course, every image we see is of a younger universe, but it’s usually only younger by a few billionths of a second – the time light takes to cross a room.)<br /> If we could see to infinity, we wouldn’t see Big Bang space as completely filling three-dimensional space. Looking farther and farther, we’d see the universe getting smaller and smaller (because younger and younger), until it’s a point at T = 0. But that’s just because we’re looking back in time. Though we can’t see it because of the finite speed of light, a Big Bang universe can be a fully three-dimensional surface of a hypersphere.<br /> But I don’t think we live in a Big Bang universe. Due to the nature of an information-space universe, it looks quite a bit like a Big Bang universe, and that it started with a Big Bang is a natural first conclusion to reach, based on general relativity and the Hubble redshift. Note that the idea of the Big Bang – space exploding from an initial point – while seeming indisputably established, is less than 100 years old, and has been the predominant theory of universal structure for less than 50 years.<br /> A Big Bang universe is nearly the same everywhere – the result of a uniform outward expansion. But a universe that doesn’t blow up all at once isn’t the same everywhere. It has an active center and burned-out and collapsed outskirts clustered close to what looks like T = 0. This universe may not be perfectly three-dimensional – space is highly curved and riddled with collapsed stuff near the apparent origin, which may mean that space is effectively less than three-dimensional at great distances."<br /><br />(27.)<br /><br />"I think the universe isn’t inherently unstable in size, with overall stability being a characteristic of an information-based universe. That is, though parts of it can expand and contract, the universe isn’t going to keep flying apart to some cold, thin oblivion or collapse into an infernal dot. (At least without some outside agency acting upon it. The loss or degradation of the physical structure which supports the universe would result in the loss of the information within the universe. As the universe loses information, it would become less well-defined, which might look like a collapse and heating up of the universe – a big bang in reverse.) The scale and size of the universe should be roughly proportional to the amount of information it contains (with local scale and size depending on the information/matter distribution as viewed from each particular neighborhood)."<br />(30.) <br /><br />"In a Big Bang universe, it’s unlikely that there aren’t a bunch of civilizations a million years old and more. Unless something consistently wipes out civilizations, which would be weird. Or civilizations link up or are colonized into super-civilizations extending across swaths of the galaxy. So the question becomes, what does a civilization do for a million years or ten million or a billion? I’d guess that there’s some principle that the number of interesting things to do increases along with the computational power of your brain (or your brain plus your super-computing add-ons). Otherwise, you and your civilization would go nuts from boredom.<br /> In an informational cosmology universe, civilizations could survive for longer than the apparent age of the universe. You could have civilizations tens or hundreds of billions of years old or more. I’m guessing that if this is the case, then such civilizations are very involved in the business of the universe. They have a good idea of the universe’s objectives, and they help with its operations. A big, old, highly organized universe might include highly developed technicians. Kinda doesn’t make sense that it wouldn’t.<br /> I imagine that, among other things, long-lasting civilizations might be able to manipulate quasars to hose down dormant galaxies with neutrinos, awakening those galaxies. (Can also imagine this might be wrong and dumb.) Can’t imagine how a civilization or entity could persist for 100 billion years without going stir-crazy, but it has 100 billion years to figure out fun things to do. (A hundred billion years is the ultimate endless Sunday afternoon.)"<br /> (73.)<br /><br />"With regard to time, I think the biggest question is, if the universe is vastly, wildly ancient, with its Big Bang age only an apparent age, why does the universe look so precisely as if it had a Big Bang? The answer must have to do with the nature of information. (Or with me being wrong. But I’m not.) The active center of the universe is where new information is being formed. Protons entering the active center are new – either they’ve been created from neutrons in collapsed matter, or they’ve come from a soup of unstructured primordial matter around T = 0. (I picture space around T = 0 consisting of collapsed galaxies, separated by their Hubble/general relativistic vectors along with a large local gravitational constant, all suspended in a dense primordial soup.)<br /> All the protons are new, though most of them are contextualized by the once-collapsed and now uncollapsing galaxies they’re part of. They all enter the active center from close to T = 0. The protons’ (and electrons’) interactions with each other puff up the space they share in what looks like a Big Bang. Galaxies don’t have to all enter the active center at the same time. Since all galaxies enter from close to T = 0, more recently lit-up galaxies look like they’re located in part of the universe that’s distant from us, so we’re seeing them earlier in their existence.<br /> The proton interactions have to start from around T = 0. They have to create the space they’re in – the active center, which, as galaxies light up, expands like a Big Bang universe. The protons and their galaxies create information through a shared history that plays out in what looks like a Big Bang – they enter at the beginning of apparent time, and space expands around them.<br /> Some conceptual trouble comes when galaxies burn out. They recede from the active center, which means they’re moving backwards in apparent time. I guess this is okay. Observers within a burned-out galaxy would see something like a Big Crunch, I suppose.<br /> The apparent age of the universe could stay roughly the same for a very long time, as newly lit-up galaxies enter from near T = 0 and burned-out galaxies recede back towards T = 0. Or the apparent age can change as more or less business is done in the active center. You could have relatively few galaxies in the active center, with the universe kind of being asleep, or you could have a relative multitude."<br />(78.) <br /><br /><br />links:<br /><a href="http://en.wikipedia.org/wiki/Richard_G._Rosner">http://en.wikipedia.org/wiki/Richard_G._Rosner</a><br />http://www.youtube.com/watch?v=ndW5uiwexL8 <br />https://www.youtube.com/watch?v=yBLEjWj2isc&list=UUMY8Yerwlrjng_MfhvQkyKA<br />AdamLorehttp://www.blogger.com/profile/05980568839722473163noreply@blogger.com0tag:blogger.com,1999:blog-101584470909732121.post-3508013175290664302014-12-09T21:33:00.003-08:002014-12-09T21:33:45.321-08:00Blue Outliers<h3><span class="mw-headline" id="Blue_outliers">Blue outliers</span></h3><h1 class="title mathjax"><span style="font-size: small;"> </span></h1><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-DSTWqd40C8M/VIfbHeO38lI/AAAAAAAABaM/T6qNtFZ2xLg/s1600/blueshift.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://4.bp.blogspot.com/-DSTWqd40C8M/VIfbHeO38lI/AAAAAAAABaM/T6qNtFZ2xLg/s1600/blueshift.png" height="297" width="400" /></a></div><h1 class="title mathjax"><span style="font-size: small;"> </span></h1><h1 class="title mathjax"><span style="font-size: small;"> </span></h1><h1 class="title mathjax"><span style="font-size: small;">The Largest Blueshifts of [O III] emission line in Two Narrow-Line Quasars</span></h1><h3><span style="font-size: small;"><span style="font-weight: normal;"><span class="mw-headline" id="Blue_outliers"></span></span></span><span style="font-weight: normal;"><span class="mw-headline" id="Blue_outliers">http://arxiv.org/abs/astro-ph/0409546</span></span></h3><h3><span class="mw-headline" id="Blue_outliers"> </span></h3><span style="font-size: small;"><b>The Narrow-Line Region of Narrow-Line Seyfert 1 Galaxies </b></span><br />http://arxiv.org/abs/1106.4898 <br /><br /><h3><span class="mw-headline" id="Blue_outliers"> </span>On the nature of Seyfert galaxies with high [OIII]5007 blueshifts </h3><h3><span style="font-weight: normal;">http://arxiv.org/abs/0803.0240 </span></h3><h3><br /></h3><h3>The blueshift of the [O III] emission line in NLS1s </h3><h3><span style="font-weight: normal;">http://arxiv.org/abs/astro-ph/0508570 </span></h3><h3> </h3><h3>Searching For the Physical Drivers of Eigenvector 1: Influence of Black Hole Mass and Eddington Ratio </h3><h3><span style="font-weight: normal;">http://arxiv.org/abs/astro-ph/0307367</span></h3><h3><br /></h3><h3>Kinematic Linkage Between the Broad and Narrow Line Emitting Gas in AGN </h3><h3><span style="font-weight: normal;">http://arxiv.org/abs/astro-ph/0207387 </span></h3><h3><span class="mw-headline" id="Blue_outliers"> </span></h3><h3><span class="mw-headline" id="Blue_outliers">An excess of mid-IR luminous galaxies in Abell 1689? </span></h3><h3><span class="mw-headline" id="Blue_outliers"><span style="font-weight: normal;">http://arxiv.org/abs/astro-ph/0007437</span></span></h3><h3><span class="mw-headline" id="Blue_outliers"> </span></h3>There are faraway <a class="mw-redirect" href="http://en.wikipedia.org/wiki/Active_galaxies" title="Active galaxies">active galaxies</a> that show a blueshift in their <a href="http://en.wikipedia.org/wiki/Oxygen" title="Oxygen">[O III]</a> emission <a href="http://en.wikipedia.org/wiki/Emission_spectrum" title="Emission spectrum">lines</a>.

That is because General Relativity predicts there to be a point in time at which the temperature, density, and curvature of the Universe are all infinite, a situation mathematicians call a singularity. To a physicist this means that Einstein's theory breaks down at that point and therefore cannot be used to predict how the Universe began, only how it evolved afterwards. So although we can employ the equations of general relativity and our observations of the heavens to learn about the Universe at a very young age, <b>it is not correct to carry the Big Bang picture all the way back to the beginning.</b>AdamLorehttp://www.blogger.com/profile/05980568839722473163noreply@blogger.com0tag:blogger.com,1999:blog-101584470909732121.post-36230818637311482502014-04-21T22:04:00.002-07:002014-04-21T22:06:10.463-07:00Singularities "cured" by String TheoryBriane Greene<br />The Hidden Reality<br />pg. 111<br /><br /><div class="separator" style="clear: both;
