Speed of Light

[hybrid]

how do you produce a single photon to be used for experiment?

photon is a theoretical particle . it is a result of mathematical calculation. you use calculator to get the value of photon energy.

or you measure the frequency band from a spectrometer and say aha that's a photon. if it is red we say low energy photon and if it is violet we say high energy photon.

No idea how they fire a photon.

Oh yeah photon energy...

True enough it's a model and sometimes a wave sometimes a particle sometimes a wave packet and sometimes a spinning little line. Whatever works.

In motion, if you encompass all motive things and figure a speed relative to all them, space being the 'between bit', the aspect of dimension is still 'between' ... errrr... I mean dimension is 'between'.

All these fifty years of conscious brooding have brought me no nearer to the answer to the question, 'What are light quanta?'

In that case, nothing remains of my entire castle in the air, gravitation theory included, [and of] the rest of modern physics. (Albert Einstein, 1954)

particles are a meaningless concept without the concept of fields. they go hand in hand.

here's another one ....

When forced to summarize the general theory of relativity in one sentence:
Time and space and gravitation have no separate existence from matter. ...
Physical objects are not in space, but these objects are spatially extended. In this way the concept 'empty space' loses its meaning. ... Since the theory of general relativity implies the representation of physical reality by a continuous field, the concept of particles or material points cannot play a fundamental part, ... and can only appear as a limited region in space where the field strength / energy density are particularly high. (Albert Einstein, 1950)

ps. hi sam, is this what you are trying to brought up ?

Heya back and yes very much to the point and thank you for the defining. The field cannot be defined therefore the objects within that field are without a base for definition. Not to mention they have no physical mass, it just portrays similair habits in the form of photon matter. Who's to say it takes the form of photons with what we know about sub-atomic mass and how it can be influenced from observation. It would be easier for me to say a photon is the reflection of what light takes for perception.

well for sure the so called photon is the amount of "binding" energy an electron contained. meaning to jerk off an electron from its orbit around the nucleus you need a specific amount of energy. this energy is what is being measured as photon.

so what actually travels at c is the electron as it takes a new orbit. since the appearance of the electron to its new orbital is instantaneous with the measurement of the photon spectrum. thus the photon's velocity is also the electron's velocity.

the weird thing about this is that electrons don't travel in space as bullets do, they "jump" (the so called quantum jump). so there is no space from which the electron travels, instead it can be thought that space itself is stretch out when the electron takes a new orbit ( like a surfer carried by the waves). so c is actually the rate in which the amount of space is being created (imagine a rising dough as it expands but becomes less dense at the same time) per unit time.

in de broglie theory of matter waves, electron is represented by two waves. the group waves (as the particle velocity) and the phase waves ( as the pilot wave). the phase waves are calculated to have a C^2 ( c x c) velocity. an imaginable high speed, from our perspective, almost instantaneous. LOL

A truely impressive speed HAHA, I remember going over the units of energy needed to achive even 1 km/s at those speeds and how it multiplies exponentialy. I was awed by the energy needed to attain even 1 km/s compared to the previous.

to reach the speed of the photon,
you need an energy equal to all the energy of the known universe.

So in other words... if someone whent the speed of light mainting a mass, it would be the end of time as we know it. awsome. I think we better start investing in wormhole technology. :P
