Black Holes Do Not Exist, claims Mersini-Houghton

Tom,

I see you similar to Cauchy in that he lost all but one of his students. At least you lost me. While your stuff is easily understandable by means of e.g. http://physicsinsights.org/lagrange_1.html , I cannot see how it relates to my seriously meant claim that singularities in physics are mathematical artifacts of pebble-like numbers. Doesn't deliberate distraction indicate lacking arguments?

Tom,

It seems even the technology is conspiring against my education. For some reason that download came up blank.

To give a brief observation of the title though, doesn't the speed of light limit how much information from the global context into the local event limit what can be known of the input, which limits the effectiveness of least action as an effective tool?

Eckard,

I'm not trying to win a contest. There are many methods of applied mathematics that aim for the same goal. You write, "I cannot see how it relates to my seriously meant claim that singularities in physics are mathematical artifacts of pebble-like numbers."

You may be serious with your claim, yet it isn't true. A physical singularity is space collapsed to a point, which so far as we know is a physical impossibility; it certainly isn't analogous to a pebble. Cauchy, Dedekind, Weierstrass, Weyl, Brouwer -- were all essentially analysts who appreciated the value of the infinitely small, to help lead us to an understanding of the limits of the finitely large. Those limits are determined by boundary conditions -- the challenge to foundational physics is to replace arbitrarily chosen boundary conditions with a mathematically complete theory that generates its own boundaries. In quantum foundations, that leads to such discrete models as the many worlds hypothesis; in classical physics, it leads to analytical frameworks that accommodate continuous measurement functions.

"Doesn't deliberate distraction indicate lacking arguments?"

I suppose it does. My arguments have always been based on well known mathematics.

I'm sorry, John. I should have saved it as a PDF. Attached.Attachment #1: The_principle_of_least_action_means_that_there_is_no_barrier_between_local_events_and_global_structure.pdf

I think this is pretty good, too.

Eckard,

What is confusing to me is why you seem to see things as if it is common for others to see numbers as being the value only (pebble-like) rather than the accepted concept of 'place : value' being dependent on the dimensionless interval between places on the number line being a constant. We can illustrate a number line with a calibrated interval, but it's really as dimensionless as is a Euclidean point. I think John Merryman has difficulty with that composite concept of numbers, but that may arise from his experiencing a form of epilepsy. Maybe I'm just sloppy, but I really don't care how many angels dance on the head of a pin. I'm having enough challenge catching up with math that most here consider routine. :-) jrc

Argh.

Yes, excellent Steve..

This emphasizes the point I've made about Quantum-Classical convergence, in comments above. The two contenders will instead be seen as two sides of the same coin, but it may take a while. I think there is too much politics involved, however, so it required someone like Hawking to comment before certain evidences became admissible, but finally the logjam is broken and progress is occurring.

Tom,

While I'm not conversant on the details, I don't have any issue with the general idea. There are infinite/endless feedback loops feeding through every event and they all interact. I find the classic paradigm to be reductionistically mechanistic. Remember I spend my life dealing with animals and this does seem intuitive to me. It just seems that modeling it within the framework of linear rationality creates its own conceptual feedback loops which legitimately take a lifetime to internalize.

It is not that I seriously do not respect this commitment, but from the point of view of an outsider, there is seeming evidence of missteps along the way, leading to the various previously mentioned patches and extrapolations. We have certainly argued them repeatedly and I realize you are not going to give my side of the debate anymore consideration than if I were to declare the moon made of green cheese. So it does seem moot to continue.

John C,

I do have some appreciation of numbers as different categories of abstractions. A title of one of my essay entries was "Comparing Apples to Inches." Much of the conflict between Tom and I has to do with me not accepting spacetime as a physical reality, rather than just a mathematical model. I see measures of distance as measures of space as a real dimensionality, while measures of duration being of actions occurring within this spatial void. With the resulting relations similar to that between pressure or temperature and volume.

I also have to say my limited interneting time is being consumed by trying to follow the increasing pace of world events. The temperature is rising.

John M

Tom,

Of course you refer to well known mathematics. I am aware of questioning very basic tenets. When I asked for the very zero between IR and IR- I was not alone. Terhardt did also deal with related imperfections of theory. Professors of mathematics shrug their shoulders. David Joyce confirmed some interesting ideas in my essay 833. He gave me valuable tips in addition to literature in German language, e.g. by Detlev Spalt and by Oskar Becker. Figs. 3 and 4 of essay 1364 should be understandable even to experts like you.

You mentioned Augustin Lois Cauchy, and Cauchy is even used as to describe a mathematical property. As Spalt revealed, Cauchy himself cautiously avoided how his view was interpreted. Among others who contributed to, supported or at least tolerated the relapse into the archaic pebble-like notion of number were Bolzano who wrote "Die Paradoxien des Unendlichen" and who coined the notion Menge (set), Dirichlet, Heine, Weierstrass. Even Abel might have played a role by blaming mathematics being putatively in a mess.

A main argument of me is that mathematicians like Ebbinghaus admit difficulties to understand what makes real numbers different from rational ones. I understand the same number as qualitatively quite different if seen as real or rational, respectively. Weyl spoke of bones within a sauce. I feel forced to see the bones part of the sauce. That's why ) and ] must not be distinguished in IR.

"Much of the conflict between Tom and I has to do with me not accepting spacetime as a physical reality, rather than just a mathematical model."

John, the conflict is in your not understanding that it's the correspondence between a mathematical model and the physics it describes that determines whether something is physically real.

Look at it this way -- flying a remote control airplane depends on the programming of the controller as well as the skill of the pilot. The pilot's skill would be irrelevant, however, unless the controls responded in the expected way. The experiments supporting spacetime do produce results consistent with the programming, i.e., the mathematical model.

You are right that the Mersini-Houghton does ends up in an accretion cycling or bouncing of Hawking radiation near the event horizon. That is not a black hole, but rather a steady state that has some decay.

The Mitra ECO does not seem to bounce, but does not seem to decay either, just exists as a steady state near the event horizon.

What I meant is that there does not seem to be any evidence for significant recycling of galaxy energy back to matter over the life of the universe. That there is recycling of matter is certain...stars live, die, and form new stars. Galaxies only seem to live and grow by merging...they never seem to die.

There is a long universe cycle 27 Byr contracting universe cycle, 13.5 Byr expansion of an antimatter antiverse followed by a 13.5 Byr contraction of a matter universe. We are 3.4 Byrs into contraction.

Tom,

The correspondence has to do with some very specific relationships between measuring distance and duration in different circumstances and how they are affected similarly. From this is derived the notion that the four dimensional geometry derived from this relationship is more fundamental than the actual process being measured. For example, it is then argued that the vacuum of space itself can expand and this explains cosmic redshift. The utter fatuousness of this proposal being that they forgot that in order for it to be relativistic, the speed of light would have to increase, in order for it to remain constant to this expanded space.

Now I realize that what you hear when I make this point is "The moon must be made of green cheese!!!" So I don't expect you to respond with anything more than a hurrumph.

Regards,

John M

Peter, Steve,

There are a variety of ways the universe could be considered as "steady state," so avoiding the term only validates those insisting on a universe which doesn't fully recycle. Eventually we will accept energy is conserved, even that which is radiated for tens of billions of years. As such no new sources are necessary.

In fact, it was the proposition that expansion and gravitational contraction are effectively balanced in overall flat space, since proven, which first led me to consider that cosmology overlooks its own evidence, in order to promote this Big Bang model.

john M

"So I don't expect you to respond with anything more than a hurrumph."

Really? You think it deserves that much? Come on, John, put some actual references and facts into your rhetoric and use your powers for good.

Tom,

All the literature of which I'm aware assumes light is just being carried along by this expansion, even though the expansion is based on the redshift of that very light and the fact we appear as the center would be perfectly explained by an optical effect, since we are at the center of our view of the universe, but of which there is no apparent reference or debate.

There is no career in raising questions about the model, only in extending it. If you notice, the only reason this debate about black holes even occurs, is because extensions of GR and QM clash at this juncture.

So I'm afraid mere logic doesn't measure up to conclusions required to support theory. It's all a green cheese moon, if it isn't drawn from the canon.

Regards,

John M

"All the literature of which I'm aware assumes light is just being carried along by this expansion,"

What literature claims that light and spacetime are the same thing? For if we speak of an expanding universe without boundary, this statement is surely implied by that one. Do you want to stand on your own authority, or cite the source, so it can be challenged?

" ... even though the expansion is based on the redshift of that very light and the fact we appear as the center would be perfectly explained by an optical effect,"

An optical effect is only the passive recording of a phenomenon. Redshifts and blueshifts simply describe the limits of the spectral range from infrared to ultraviolet. It explains nothing; it only obeys the laws of classical mechanics that we already know from empirical data alone.

" ... since we are at the center of our view of the universe, but of which there is no apparent reference or debate."

Subjectively, any particle is at the center of its own universe (Or as Hilbert is reputed to have said, "Some have a mental horizon of measure zero, that they call their point of view."). Objectively -- scientifically -- the universe has no center; every arbitrarily chosen point is the origin of creation. Study that principle of least action, John. You will realize that it's much more than what you think of as a mere mathematical model.

And meditate on Fermat, who discovered the principle of least action via his study of optics. You'll realize that there cannot possibly be a center to an expanding universe -- it's expanding from every point. If light were only carried along by the expansion, as your unnamed source claims, there would exist nothing to expand, because light travels at a measured speed and to be physically real, it has to be " ... independent in its physical properties; having a physical effect but not itself influenced by physical conditions."

(~ Einstein)

Because space is not independent in its physical properties and thus not physically real ...

And because time is not independent in its physical properties and thus not physically real ...

And because spacetime is independent in its properties and physically real, the motion of light (electromagnetic radiation) is measured only relative to spacetime -- which not only guarantees that spacetime and light are independent of each other; it guarantees that each has a physically real effect on the other. Furthermore:

Because our knowledge of physical effects depends on physical measurement, the expansion of space is constrained by the constant speed of light, a spacetime symmetry elegantly explained by Einstein, Lorentz and Poincare as the effects of length contraction and time dilation.

I should not have failed to mention Fitzgerald in that last post re: length contraction and time dilation.

Do dark matter and gravitons have wave-functions? I assume the answer is: nobody knows. Therefore, it would be impossible for you to discount the existence of things like ghosts or an afterlife based upon scientific thought. Am I wrong?
