EINSTEINIANA AND JOURNALISTS' HONESTY
In 1907 Einstein relalized that Newton's emission theory of light
correctly predicts the variation of the speed of light with the gravitational potential. Two major implications were almost obvious - that the emission theory correctly predicts the variation of the speed of light with the speed of the emitter (Einstein's 1905 light postulate is false) and that the emission theory correctly predicts the gravitational redshift factor: http://www.pitt.edu/~jdnorton/papers...UP_TimesNR.pdf John Norton: "Already in 1907, a mere two years after the completion of the special theory, he [Einstein] had concluded that the speed of light is variable in the presence of a gravitational field." http://www.logosjournal.com/issue_4.3/smolin.htm Lee Smolin: "Special relativity was the result of 10 years of intellectual struggle, yet Einstein had convinced himself it was wrong within two years of publishing it." http://www.blazelabs.com/f-g-gcont.asp "So, faced with this evidence most readers must be wondering why we learn about the importance of the constancy of speed of light. Did Einstein miss this? Sometimes I find out that what's written in our textbooks is just a biased version taken from the original work, so after searching within the original text of the theory of GR by Einstein, I found this quote: "In the second place our result shows that, according to the general theory of relativity, the law of the constancy of the velocity of light in vacuo, which constitutes one of the two fundamental assumptions in the special theory of relativity and to which we have already frequently referred, cannot claim any unlimited validity. A curvature of rays of light can only take place when the velocity of propagation of light varies with position. Now we might think that as a consequence of this, the special theory of relativity and with it the whole theory of relativity would be laid in the dust. But in reality this is not the case. We can only conclude that the special theory of relativity cannot claim an unlimited domain of validity ; its results hold only so long as we are able to disregard the influences of gravitational fields on the phenomena (e.g. of light)." - Albert Einstein (1879-1955) - The General Theory of Relativity: Chapter 22 - A Few Inferences from the General Principle of Relativity-. Today we find that since the Special Theory of Relativity unfortunately became part of the so called mainstream science, it is considered a sacrilege to even suggest that the speed of light be anything other than a constant.

The result is c'=c(1+V/c^2) where V is the gravitational potential relative to the point where the measurement is taken. 1+V/c^2 is also known as the GRAVITATIONAL REDSHIFT FACTOR."

Instead, the "speed of light" at a each point depends on the direction of the light ray through that point, as well as on the choice of coordinate systems, so we can't generally talk about the value of c at a given point in a non- vanishing gravitational field. However, if we consider just radial light rays near a spherically symmetrical (and non- rotating) mass, and if we agree to use a specific set of coordinates, namely those in which the metric coefficients are independent of t, then we can read a formula analogous to Einstein's 1911 formula directly from the Schwarzschild metric.

EINSTEINIANA AND JOURNALISTS' HONESTY
Einsteiniana's idiocy is contagious and I fell victim when I said in
my original message: "This relatively honest period in the development of Einsteiniana ended in 1915 when Einstein suddenly discovered that light particles are two times heavier than other particles..." "However the confusion in Einsteinians' minds is never enough - any idiotic thesis advanced in Einsteiniana has an equipotential and equally idiotic antithesis. So, apart from being two times heavier than other particles, light particles are massless, that is, not heavy at all." In fact, in 1915 Einstein discovered that gravity affects light particles more strongly than other particles and makes them accelerate two times faster. That is the idiotic 1915 thesis presented correctly. As for the equipotential and equally idiotic antithesis ("light particles are massless, that is, not heavy at all"), it is usually taught by Stephen Hawking: http://www.amazon.com/Brief-History-.../dp/0553380168 Stephen Hawking, "A Brief History of Time", Chapter 6: "Under the theory that light is made up of waves, it was not clear how it would respond to gravity. But if light is composed of particles, one might expect them to be affected by gravity in the same way that cannonballs, rockets, and planets are.....In fact, it is not really consistent to treat light like cannonballs in Newton's theory of gravity because the speed of light is fixed. (A cannonball fired upward from the earth will be slowed down by gravity and will eventually stop and fall back; a photon, however, must continue upward at a constant speed...)"

EINSTEINIANA AND JOURNALISTS' HONESTY
Genuine honesty:
http://www.nature.com/nature/journal...l/433218a.html NATU "EINSTEIN RESTORED FAITH IN THE UNINTELLIGIBILITY OF SCIENCE. Everyone knew that Einstein had done something important in 1905 (and again in 1915) but almost nobody could tell you exactly what it was. When Einstein was interviewed for a Dutch newspaper in 1921, he attributed his mass appeal to the mystery of his work for the ordinary person: "Does it make a silly impression on me, here and yonder, about my theories of which they cannot understand a word? I think it is funny and also interesting to observe. I am sure that it is the mystery of non-understanding that appeals to themit impresses them, it has the colour and the appeal of the mysterious." Relativity was a fashionable notion. It promised to sweep away old absolutist notions and refurbish science with modern ideas. In art and literature too, revolutionary changes were doing away with old conventions and standards. ALL THINGS WERE BEING MADE NEW. EINSTEIN'S RELATIVITY SUITED THE MOOD. Nobody got very excited about Einstein's brownian motion or his photoelectric effect but RELATIVITY PROMISED TO TURN THE WORLD INSIDE OUT."

EINSTEINIANA AND JOURNALISTS' HONESTY
Genuine honesty:
http://www.irishtimes.com/newspaper/...275683050.html "...Isaac Newton would be astounded that his theories of motion and gravitation had been usurped by Einstein's theory of relativity. Christopher Wren would be amazed that modern astronomical measurements had led to the discovery that we live in an expanding universe that was once smaller than an atom. But what would surprise the founding members most is that these, and other discoveries, remain the preserve of a few. Far from being an indispensable part of the human experience, science has remained a specialised subject understood by only a fraction of society. Does it matter? (...) A second, and often overlooked, reason for a public understanding of science is that science is part of the human experience, just as history and music are. Not everyone may want to partake in the actual discovery of the workings of the natural world, but they deserve to know what has been discovered! This science-as-culture argument was first articulated by the physicist C P Snow when he realised that he could engage in literary discussion with friends in the humanities, while they knew nothing of his subject. Indeed, he felt that the general public was being cheated out of a scientific education. This coincides with my own belief, and that of many scientists, that society has a right to know the discoveries of modern science. Indeed, I believe society also has a right to know how those discoveries were made, as the story of unfolding scientific discovery is an important part of human history."

This last idiocy misled me into construing the journal Nature's text: "Gravity is mercilessly impartial - on Earth, it accelerates light and heavy objects alike with a tug of 9.8 metres per second squared." as "Gravity is mercilessly impartial - on Earth, it accelerates [particles of] light and heavy objects alike with a tug of 9.8 metres per second squared." Needless to say, if my construal had been accepted by the scientific community, Nature would have vindicated Newton's emission theory of light and the journal would be in serious trouble (attacking Einstein and vindicating Newton is a crime against the civilization). Then vigilant Einsteinians informed Nature about the problem, editors changed the places of "light" and "heavy" and the crime against the civilization was avoided: http://www.nature.com/news/2010/1006....2010.303.html NATU "Gravity is mercilessly impartial - on Earth, it accelerates heavy and light objects alike with a tug of 9.8 metres per second squared."

Get over it. http://www.nature.com/news/2010/1006....2010.303.html NATU "Gravity is mercilessly impartial - on Earth, it accelerates heavy and light objects alike with a tug of 9.8 metres per second squared." The article is not about gravity's effect on electromagnetic radiation. It's about gravity's effect on a weird state of *matter*. But so what? Let's talk about gravitation and EM radiation *anyway*; screw any wannabe censors! If as you say the speed of light is not constant, let's posit dropping a battery-powered radio transmitter straight down along its antenna's line-of-sight toward a convenient plane reflector Pulse it one time while it's falling at some fraction of c, let's call it dv. Afterward the antenna is basically just a mirror. There's a clock midway up that releases the transmitter and later tells it to pulse, and also tells us at the bottom when all this happens. When do we first see photons arrive at the reflector? If velocities add the way you say they do... The first pulse of photons travels downward at c +dv, hits the plane reflector and returns upward still at c+dv. It hits the transmitter antenna *and bounces off*, adding the now-greater transmitter's velocity to its own, heading down faster than the original photons. For a smaller distance. This repeats until the many-times-reflected photons have (as far as we can measure) infinite speed. That a problem for you? Mark L. Fergerson |
