Essay Abstract

In this paper we present the anthropic type description of the history of the Universe. The evolution of the the radius Universe, velocity of expansion and acceleration are calculated. In addition the cosmological parameter Λ in de Sitter Universe is calculated. The agreement with the existing observational data is good. The future of the Universe is diagnosed and discussed

Author Bio

Miroslaw Kozlowski, professor emeritus Warsaw University is the author above 200 papers in cosmolohy and ultra-short laser pulses and three monographs published in USA ( Springer and others)

Resp Prof Miroslaw,

Thank you for developing a nice essay "diffusion model for the expansion of the Universe". I sincerely feel you should account for about 33% of the Galaxies that are coming near to SUN , which are Blue shifted Galaxies. I feel there is an estimate of 20 % are galaxies that don't show any shift. How will you account for these Galaxies? What are the measures you provided in your model for these? I hope you don't mind explaining your model in some more detail...

Best

Dear Miroslaw

It would be more valuable if you apply that formulas and equations in a small scale and close to reality.

To change the atmosphere "abstract" of the competition and to demonstrate for the real preeminent possibility of the Absolute theory as well as to clarify the issues I mentioned in the essay and to avoid duplicate questions after receiving the opinion of you , I...

Professor Kozlowski,

I thought your essay was very interesting. There is one comment I would care to make about it.

You wrote, “After the work of Supernova detecting groups the consensus for the acceleration of the moving of the spacetime is established.

I do not see how a real star could collide with another real star. For one thing each real star is unique. Not only that, each real star is set at a unique distance from all other real stars. In order for a real star to collide, it would have to move away from the light it had already emitted in the opposite direction to that of the light it had already emitted. Notably, according to the National Geographic website only fuzzy images of purported fragments of a possible Supernova have ever been photographed.

I would hope that your pages of calculations are based a bit more firmly in the realm of reality.

Joe

Miroslaw,

If given the time and the wits to evaluate over 120 more entries, I have a month to try. My seemingly whimsical title, “It’s good to be the king,” is serious about our subject.

Hello Pr. Miroslaw

I agree with you. I rated it 9, dropping a point only because it is faintly off topic, but is exactly relevant to foundations. I don't understand why this is presently rating so low, especially against essays that are so non-foundational. I would have thought it should be at or near the top. On reflection, I should have rated it a 10 to make up for other members' lack of attention, but too late now.

I am keen to have you consider my essay which shows why time is, what time is, and why it can only be discrete, at least at the foundational level of the universe. My essay is necessarily a compact argument, although every claim has a strong justification (indeed, under Descartes' Method of Doubt it seems to be indubitable).

Best wishes

Stephen Anastasi.

Professor Kozlowski,

Very interesting thought process with some nice reminders of the properties of the physics. "fields with odd-integer spins can produce both attractive and repulsive forces; this with even-integer spins such as scalar and tensor fields produce only an attractive force”.

I remember learning this a long time ago, but forgot why this is true. Indeed, I don't think I ever got an answer from anyone on that, and it seems odd to me now. For example, are we certain that antimatter is gravitationally attracted to matter? This would seem a very difficult (but perhaps feasible) experiment to do in an accelerator.

Certainly a thought provoking argument, with calculations that land perhaps in the "zone" of feasibility. I must read this more carefully and follow up after the contest.

In the meantime, my own investigations lead me to a different conceptualization of "time atoms" as the photon traversal between two atoms. This (finite) traversal down a "one dimensional path" defines time (and the transfer of information from the emitter to the absorber). The interesting aspect of this is that if the role of emitter and absorber were now to be reversed and the photon were to return back to the original atom, would time be reversed also. Furthermore, if a photon bounces back and forth between these two atoms, would this behavior it manifest itself with the same measurements we get in Bell tests of entanglement?

Good luck in the contest, I gave you high marks for a quality idea and description.

Kind regards, Paul
