Re: Time
I suppose it would be easy for the merchant class armed with weapons of mass destruction like flintlocks to say "these creatures which will make good slaves are not men." But in any case, such is not of cosmology, so should be discussed further only when space travel gets to the point where we could return ships full of slaves from the newly subjected worlds.makc wrote:slaves were considered to be different from men, see http://en.wikipedia.org/wiki/PolygenismLoco wrote:If all men were created equal, why did the beholders of self evident truth embrace slavery?

p.s. here is what it looks like when you cross event horizon.mother wiki wrote:The apparent singularity at r = rs is an illusion; it is an example of what is called a coordinate singularity. As the name implies, the singularity arises from a bad choice of coordinates or coordinate conditions. By choosing another set of suitable coordinates one can show that the metric is well-defined at the Schwarzschild radius. See, for example, Lemaitre coordinates, Eddington-Finkelstein coordinates, Kruskal-Szekeres coordinates or Novikov coordinates.

Time, Incompleteness and Singularity in Quantum Cosmology
Authors: Philip V. Fellman, Jonathan Vos Post, Christine Carmichael, Alexandru Manus, Dawna Lee Attig
(Submitted on 27 May 2009)
Abstract: In this paper we extend our 2007 paper, Comparative Quantum Cosmology: Causality, Singularity, and Boundary Conditions, arXiv:0710.5046 to include consideration of universal expansion, various implications of extendibility and incompleteness in spacetime metrics and, absent the treatment of Feynman diagrams, the use of Penning trap dynamics as explained by Ferdandez and Velazquez to describe the Hamiltonians of space-times with no characteristic upper or lower bound and to compare the above with Peter Lynds' conjecture on the specialness of initial conditions in inflationary theory in quantum cosmology.

Comparative Quantum Cosmology: Causality, Singularity, and Boundary Conditions
Authors: Philip V. Fellman, Jonathan Vos Post, Christine M. Carmichael, Andrew Carmichael Post
(Submitted on 26 Oct 2007)
Abstract: In this review article we compare the recent work of Peter Lynds, "On a finite universe with no beginning or end", with that of Stephen Hawking, primarily "Quantum Cosmology, M-Theory, and the Anthropic Principle", and two foundational works by Sean M. Carroll and Jennifer Chen, "Does Inflation Provide Natural Conditions for the Universe" and "Spontaneous Inflation and the Origin of the Arrow of Time", in order to evaluate their comparative treatments of the nature and role of causality, time ordering, thermodynamic reversibility, singularities and boundary conditions in the formation of the early universe. We briefly reference Smolin and Kauffman's recent arguments with respect to possible processes of "evolutionary selection" in early universe formation as an alternative explanation to key elements of Hawking's earlier "M-Theory", and its attendant anthropic principle. We also briefly excerpt a short section of Smolin's recent work on topology in quantum loop gravity, simply as an illustrative example of the type of complex quantum topological transformation which he offers as a theoretical alternative to string theory in quantum cosmology.

Hi harry..
You can think along that line, or choose to think along reality, think along the lines of communication with EMR and what effects it speed.Scroll to the bottom of the link i provided.. And it says This: At the center of the black hole is a singularity, a point of infinite of curvature, where space and time as you know them come to an end. http://jilawww.colorado.edu/~ajsh/insidebh/schw.html
What else does this mean? This is just one example. As they describe space Falls to the singularity ..But if the BB was also from a singularity Why is the out come Different?

Re: Time
I do not think these theories will get that far. Sooner or later something they find in the cosmos will point directly to the answer. Which will force scientists to look on our universe in a different way.Chris Peterson wrote:I mean that there is no current, well supported theory that can be used to describe the interior of a black hole.

Hypothetically: This will happen if they find a black hole or anything else that breaks the rules. I think this is more likely than solving the current problems that there are in understanding past the event horizon.

A good wife will certainly make a husband feel superior to her (while ensuring her footprint is firmly stamped on planet Earth.) Are you thinking of changing to the Hebrew or Islamic religion? Both those institutions had men (Kings of course) with hundreds of wives.harry wrote: As for slaves, and equality. We all need slaves but equality we will never have. That's why I have a wife.

Quantum Field Theory on Noncommutative Space-Times and the Persistence of Ultraviolet Divergences

(Submitted on 20 Dec 1998 (v1), last revised 13 Apr 1999 (this version, v3))
Notice the words compactness.Abstract: We study properties of a scalar quantum field theory on two-dimensional noncommutative space-times. Contrary to the common belief that noncommutativity of space-time would be a key to remove the ultraviolet divergences, we show that field theories on a noncommutative plane with the most natural Heisenberg-like commutation relations among coordinates or even on a noncommutative quantum plane with $E_q(2)$-symmetry have ultraviolet divergences, while the theory on a noncommutative cylinder is ultraviolet finite. Thus, ultraviolet behaviour of a field theory on noncommutative spaces is sensitive to the topology of the space-time, namely to its compactness. We present general arguments for the case of higher space-time dimensions and as well discuss the symmetry transformations of physical states on noncommutative space-times.

You said
The universe has no origin, it is never ending, the parts within keep on recycling one way or another.
We see it today in star formation and galaxy evolution in local galaxies and deep field images.
What is the truth?
Can we stand for the truth?

Re: Time
Now all you have to do Harry,,, is explain with your own mind and your own words why you think the universe is like you describe.(no links) But remember,, standard theories are pretty much factual.. Like the fact we can not see all the universe because light has not had time to reach us. In a never ending universe this would not be the case. or does what you describe as our universe resemble a spark in what the universe actually is? If so.. I like idea that the universe that we can see is insignificant to what it really is.

Re: Time
(My bold.) No "becoming" about it. This topic started off "out of control". It was officially disrespected by two moderators in the fifth through seventh replies and thereby declared to be a free-for-all circus. There was no integrity to preserve from the start. Anyone (including myself) who posted anything serious did so with full knowledge that it would be lost in the mix. What better repository is there for frivolous posts? It might help save some other more serious topics from their interference. Personally, I prefer pure and honest crap to pseudoscientific or philosophical babble and try to maintain a favorable ratio. Of all the non-canonical non-linear topics in this forum, this one is relatively good-natured and easily read - long may it flap in the breeze. Or not.Chris Peterson wrote:This discussion is out of control.

The trillion year cycle is pure idle conjecture without a shred of evidence, so not science at all. Sure it's possible, and it makes good imagery for daydreams, but it's just an idea with no anchor in observation.
Launching gravity sensors is fine, mapping CMBR is fine, and reconstructing the past 13.7 billion years is fine, but using CMBR measurements to infer an image of what preceded the Big Bang is hogwash. The waves-in-a-bucket analogy might be okay for the past 13.7 billion years, but it can't tell you what happened before the bucket was made or filled. I have a deck of cards that has been shuffled very many times. If I had enough echoes of the past to examine, I might be able to determine the order of the cards at any time back to their origin in a sealed package - but the creators of this video would have you believe I could tell what order they were in before the prior paper was recycled and the deck was manufactured. I don't buy it.
