Hi. Just wanna share something with you.
I'm from country where Tesla were born.
I'v seen today in some newspaper, that Tesla was claiming there are faster then light particles.
It says: 1932. in an article in Brooklyn Eagle newspaper, Tesla was claiming that all his research indicate that there are particles which carry so little electric charge and they can move faster then light. He called them "neutrons", altought neither neutrons nor neutrinos were discovered that time.
Local director of Tesla's museum here says author of that article was John J. O'Neill (he also wrote a book: Prodigal Genius: The Life of Nikola Tesla)
p.s. sry for bad English
edit: i guess only way to confirm this is to check all archives from brookly new yourk eagle from 1932 year
(if that is the right newspaper at all)
edit on 27-9-2011 by griswold because: (no reason given)
“All of my investigations seem to point to the conclusion that they are small particles, each carrying so small a charge that we are justified in calling them neutrons. They move with great velocity, exceeding that of light.” – Nikola Tesla, July 10, 1932
The Nikola Tesla quote above has been making the rounds since last week’s announcement from the OPERA research team that they had detected neutrinos that may have traveled faster than the speed of light. For the most part, this has been going under headers like “Tesla was right!”, etc.
However, a quick glance at the source of the quote shows that Tesla was, in fact, completely wrong. See the “they” in that first part of the sentence? In context of the article, that refers to cosmic rays. And cosmic rays are not neutrinos. They’re mostly highly charged protons, atomic nuclei, and electrons (and the occasional anti-particle for fun). It also probably goes without saying that cosmic rays do not, in fact, travel faster than the speed of light.

Slightly off-topic but since the thread died down I can give you my view. I don't think it's a problem with mathematics as much as it's a problem with measurement.

Regarding where you mention they have not actually proven that photons produce a gravitational field, do you think photons do regardless of the mathematics not having been irrefutably proven as of yet?
I'm of the belief if anything exists in this universe despite how minute in quantity it does dent the fabric of space and thus creates a gravitational vortex.
Drop a paper clip from your desktop to the ground. Did the paperclip move toward the ground, or did the ground move toward the paperclip, or both?
Not many people will answer both, but we are pretty confident that's what happens. The problem is, the movement of the Earth toward the paper clip is so small, how are you going to measure it? Trying to measure the gravitational field of a photon is similar in that you're trying to measure something that's very small; so small, that it's hard to measure.
Since we measure light being bent by the sun and other stars, we know photons interact with other gravitational bodies so I see no reason to doubt they exert gravity themselves, but it's so small I have no idea how to measure it. Nor do I have any idea how to measure the earth moving toward the paperclip when you drop it.
In a way this is relevant because the neutrino speed could also be a measurement problem. They think they've accounted for all measurement errors, but they may not have. 60ns is a pretty short time and there are plenty of things that could affect the measurement.

In both General Relativity and Quantum Mechanics, the speed of gravity is equal to the speed of light.
You meant if light CAN'T escape, right?

What I want to know , if light can escape a black hole can a neutrino ?
since now it is shown to travel faster than light
