Yuri Danoyan Posted November 26, 2012 Posted November 26, 2012 Persy Bridgman,American physicist,winner 1946 Nobel Prize in Physics in his book "Dimensional Analysis". was very sceptic and critical about Planck units. I have additional arguments to protect Bridgman's point of view Does all Planck units are sacred or only one? We doesn’t have guarantee G, c, are real constants or not, during the evolution of the Univertse. We doesn’t have guarantee they depend of each other or not,or 2 sides the same coin. Imagine that G and c simultaneously vary….because permitivity of vacuum vary following the evolution. But we believe: 1.Schwarshild black hole R radius G/c^2 2.Planck unit L of length G/c^3 3.Planck unit T of time G/c^5 4.Planck unit M of mass c/G What is correspond to real world? If all,it would be absurd. To my opinion only #4 linear link between G and c is real….and eternal. And #1,2,3 are fake that only teasing physicists Just in case: Max Planck, Scheinprobleme der Wissenschaft (Illusory problems of Science) http://www.quantum-cognition.de/texts/Planck_SCHEINPROBLEM.pdf Even more interesting, he warned about similar situations.
LaurieAG Posted November 27, 2012 Posted November 27, 2012 Hi Yuri, Note that the reduced Compton wavelength is used in relation to Planck length and is proportional to the Planck mass while the Compton wavelength is proportional to the inverse of the mass. http://en.wikipedia.org/wiki/Compton_wavelength The Planck mass is special because the reduced Compton wavelength for this mass is equal to half of the Schwarzschild radius. This special distance is called the Planck length (). This is a simple case of dimensional analysis: the Schwarzschild radius is proportional to the mass, whereas the Compton wavelength is proportional to the inverse of the mass.

It is disconcerting to imagine that we must extract roots in order to express the basic units in terms of fundamental parameters. (Sophisticates will recognize that extracting roots is a nonanalytic procedure, in the technical sense.) The fact that G, \, c can be expressed in terms of mp, \, c without extracting roots, but not vice versa, on the face of it suggests that the strong units are more fundamental than Planck units. (I find it remarkable that a similar conclusion is suggested by string theory, where the closed string gravitational coupling naturally appears as the square of the open-string gauge field coupling.)
Yuri Danoyan Posted November 30, 2012 Author Posted November 30, 2012 Hi Yuri, Note that the reduced Compton wavelength is used in relation to Planck length and is proportional to the Planck mass while the Compton wavelength is proportional to the inverse of the mass. http://en.wikipedia.org/wiki/Compton_wavelength Planck mass is reasonable,but my doubts concerning G and c , their internal link and variations during the evolution of the Universe.

Yuri Danoyan Posted January 12, 2013 Author Posted January 12, 2013 O.K. As you see i am I criticized the 2 from 3 Planck unitsб but also suggest a way out of this situation by varying some constants For example if the Universe have finite life time Vary:Start; Today; Finish.Gravitational …..G (10^12; 10^-8; 10^-28); G vary span of Dirac large number 10^40Speed of light in a vacuum…..C (10^30; 10^10; 10^-10)] c vary span of Dirac large number10^40 then Constants:h, Mpl, Mpr, Time of the Cycle of the Universe. h=10^-27 gsm^2/sec; Mpr=10-24g; Mpl=10^-5g ; because Mpl=sqrt(hc/G) c and G can vary synchronously
Yuri Danoyan Posted January 18, 2013 Author Posted January 18, 2013 Two events occur simultaneously at the same point in space. Is it possible to distinguish one event from another? dG/dt and dc/dt occur simultaneously at the same point in space. Is it possible to distinguish one event from another?

Yuri Danoyan Posted January 26, 2013 Author Posted January 26, 2013 Why "tandem" G and c can vary simultaneously? All cosmological models: Big Bang and Steady state, Big Freeze, Big Rip, Big Crunch, Big Bounce, Multiverse suggest variation of density of energy or matter, that mean variation of environment;. Variations of environment lead to variation of G and c. If speed of variation the same for G and c they vary simultaneously. In December 2012, a research team in China announced that it hadproduced findings which seem to prove that the speed of gravity is equalto the speed of light. The team's findings were due to be released in ajournal in 2013.http://en.wikipedia.org/wiki/Speed_of_gravity
Yuri Danoyan Posted January 27, 2013 Author Posted January 27, 2013 Sorry.... More right word than "environment" is "medium" Laws of variation G and c in the Universe can be different,but medium the same.
Yuri Danoyan Posted January 28, 2013 Author Posted January 28, 2013 The nature of reality at the Planck scale is the subject of much debate in the world of physics, as it relates to a surprisingly broad range of topics. It may, in fact,be a fundamental aspect of the universe. In terms of size, the Planck scale is extremely small (many orders of magnitude smaller than aproton). In terms of energy, it is extremely 'hot' and energetic. The wavelength of a photon (and therefore its size) decreases as its frequency or energy increases. The fundamental limit for a photon's energy is the Planck energy, for the reasons cited above. This makes the Planck scale a fascinating realm for speculation by theoretical physicists from various schools of thought. .
Kramer Posted January 28, 2013 Posted January 28, 2013 I share your opinion that Plank constants are very important issue for study. The people that thought Plank constant : mass, length frequency have nothing to do with modern physic, i think are at all wrong. But i think too that to bring above constant Plank for use in today study needs to correct them accordingly with real value of electric charge which differ from Plank,s by sqrt. of alpha (constant of fine structure). And together of it to bring importance of sqrt. of constant of gravity.It is amazing that an hypotetic Plank particle is a copy cut of common elementary particles.It is interesant that Plank mass as a black hole may be identify as a brick of elementary particles.

Yuri Danoyan Posted March 22, 2013 Author Posted March 22, 2013 My opinion about Planck units of length and time I hope to explain my suspicions. …. and share my doubts about the Planck length &time Persy Bridgman,American physicist, winner 1946 NobelPrize in Physics in his book "Dimensional Analysis". very sceptic and critical about Planck units. I have different arguments to support Bridgman's point of view. Does all Planck units have sense ? 1.We doesn’t have guarantee G, c, stay constants or not,during the evolution of the Universe. The Universe is still young(13.7) 2.We doesn’t have guarantee G, cdepend of each other or not. Version 1. G and c not depend from each other and notvary. Silent agreement all modern physicists. Version 2. G and c depend from each other and vary. Version 3. G and c not depend from each other, butdepended from third value, expandedmedium of the Universe(density of vacuum). Likely that G and c simultaneouslyvary…and have some term. They depended only from time. Nothing lasts foreverexept of time. Every exstrapolation (inflation hypothesis, etc) is false. But we naïve used formulas: 1.Schwarshild black hole R radius G/c^2 If G=f©^2??? or c=f(G) ??? 2.Planck unit L of length G/c^3 If G=f©^3 ??? or c=f(G) ??? 3.Cosmological constant If G=f©^4 ???? or c=f(G) ??? 4.Planck unit T of time G/c^5 If G=f©^5 ??? or c=f(G) ??? 5.Planck unit M of mass c/G What is correspond to real world? If all, it would be absurd Possible case when Planck unit of mass stay constant (contrary to Planck length unit and Planck time unit) when G and c simultaneouslyvary. To my opinion onlyversion #5 linear link between G and cis real…. And #1,2,3,4 are fake that only teasing physics. .
swansont Posted March 22, 2013 Posted March 22, 2013 ! Moderator Note Post moved from "Planck time, why cant we have a smaller unit of time?" because personal views are not the subject of that thread. It's more appropriate in this, previously existing, thread. Also, remember Rule 10
