Object: Mass of Light
I'm reading the theory of relativity, but I've a little problem:
Light travels with the speed of light, so its mass should be zero or
infinite. It couldn't have an endless mass and my teacher says that
light isn't really a wave but a kind of particle, so its mass couldn't
be zero..
What's the mass of light?

Light is thought to be comprised of photons which have
both particle-like and wave-like properties (depending
largely on what and how you are measuring them).
The rest mass of the photon is zero (photons move at c
always, and are never at rest as long as they exist).
In media other than a vacuum, light can move at less
than c, but this is attributed to electromagnetic
interactions with the media -- the light still moves
from encounter to encounter at c.
The photon carries energy (it can be thought of as an
energy packet) in the form of momentum. This energy
has a mass equivalent via E=m*c^2. Note that this is
not rest mass, which is zero for the photon.

Infinite would not be true and light could still have a mass.
Lightspeed does not take infinite energy.
The only speed that would need infinite energy is infinite speed.

It couldn't have an endless mass and my teacher says that

The mass can not be a complete 0 because anyone with
a brain knows a 0 mass can not have any energy.

What's the mass of light?

It is very small, it is so small that using 0 is basically
allowed as long as you include an energy equation that ignores
mass.
The basic thing is light is a dual vibration of a particle (usually an
electron)
one vibration occurs in the electric field and one in the magnetic field,
hence the electromagnetic wave.

OK spaceshit. Tell me how much energy it would take to accelerate a
proton from 0 to c+1 m/s.

The mass can not be a complete 0 because anyone with

You and Porat would be kindred spirits, fuckwit.
The photon's observed mass is consistant with zero.



What's the mass of light?


It is very small, it is so small that using 0 is basically
allowed as long as you include an energy equation that ignores
mass.

You don't even know what the equations are, idiot.
Care to quantify "very small" ? Oh wait, you are spaceshit, you are
scared of numbers because you ***** up every time you use them.


The basic thing is light is a dual vibration of a particle (usually an
electron)
one vibration occurs in the electric field and one in the magnetic field,
hence the electromagnetic wave.

Spaceshit has no idea what he is talking about, as usual. Hey spaceshit
- just because you don't know what the words actually mean does not
mean others don't.

Who cares
You are using a energy force that is limited to lightspeed
anyways.
It is still very funny you can't grasp such a fact..
It is not proof that infinite energy is needed nor
infinite mass would occur from lightspeed motion.

Lets try again, spaceshit.
Infinite energy for infinite speed implies finite energy for finite
speed. So, again, how much energy does it take for me to accelerate a
proton from 0 to c+1 m/s?
If you are incapable of answering, just say so.

<snipped rest of Eric's insultation physics>

I like "insultation physics" over "arbitrary and wrong in every way
possible" physics. I can justify insulting you by pointing out that you
are stupid. How do you justify physics that is wrong?

What kind of energy Eric?
The speed is limited by the energies own speed.
Do you have an energy source that can push thigns faster
than c yet to determine how much energy would be needed?

If you are incapable of answering, just say so.

Where is your proof that infinite energy is needed?
Prove the energy you are using can move faster than c at all
to be able to move the proton faster than c or you have no
proof at all about ho0w much energy is needed..
You are just way to ignorant to actually think about such
facts at all anymore huh?

You can not show such is needed since you don't even have

You provide an energy that can move FTL and I will show you
infinite mass will not occur.
If you provide an object traveling FTL, I can show you infinite
energy is not needed to do such.
So..
Where is your physical proof that infinite energy is needed
at all or can be shown to be needed at all?

Actually you did say infinite speed requires infinite energy.
I have marked it above so you can see it.
You misunderstand the way energy works. You are obsessing with the "speed of
the energy" being the key. This is partly because you obsess with
irrelevant, broken analogies.

at all?
Sheesh
You are so ignorant and arrogant simultaneously.

I'm reading the theory of relativity, but I've a little
problem:
Light travels with the speed of light, so its mass should be
zero
or
infinite.


For future reference, ignore spaceshit.


Infinite would not be true and light could still have a mass.
Lightspeed does not take infinite energy.
The only speed that would need infinite energy is infinite
speed.


OK spaceshit. Tell me how much energy it would take to accelerate
a
proton from 0 to c+1 m/s.


Who cares
You are using a energy force that is limited to lightspeed
anyways.
It is still very funny you can't grasp such a fact..
It is not proof that infinite energy is needed nor
infinite mass would occur from lightspeed motion.
LOL


Lets try again, spaceshit.

Infinite energy for infinite speed implies finite energy for finite
speed. So, again, how much energy does it take for me to accelerate
a
proton from 0 to c+1 m/s?


What kind of energy Eric?
The speed is limited by the energies own speed.
Do you have an energy source that can push thigns faster
than c yet to determine how much energy would be needed?


So you can't answer it. I expected nothing less from you, spaceshit.


So you refuse to even think about the limits of the
energy itself?


What energy?


The energy you are saying would need to be infinite yet
you can not even prove that energy can move something at c,
nevermind past c.

You were the one talking about infinite energy, spaceshit.



If one considers the energy of your stupidity, one finds that no amount
of it can do any useful work but the noise generated is directly
proportional to the amount present.


Still can't admit that you can not prove infinite energy is needed huh?

You were the one talking about infinite energy, spaceshit.


So, as usual, you say something stupid, and are surprised when it is
pointed out to be stupid.


As usual, you can't prove anything you are stating.
Where is your proof infinite energy is needed Eric?
What experiment shows it can come close to infinite energy
at all?
Sheesh
You are so ignorant and arrogant simultaneously.
LOL

You were the one talking about infinite energy, spaceshit.

The basic thing is light is a dual vibration of a particle (usually an

one vibration occurs in the electric field and one in the magnetic field,
hence the electromagnetic wave.

I'm reading the theory of relativity, but I've a little problem:
Light travels with the speed of light, so its mass should be zero or
infinite. It couldn't have an endless mass and my teacher says that
light isn't really a wave but a kind of particle, so its mass couldn't
be zero. What's the mass of light?

A single photon has no rest mass. A system of two or more photons,
such as that of "light" or that of an electromagnetic wave, can have rest
mass. In the center-of-momentum, the rest mass energy is equal to the
system's total energy. One cannot define a center-of-momentum for
a single photon. In the language of physics, "particle" doesn't imply
"mass".

Don't you think the mass of a *system* of two photons would be

Certainly the mass of a system of two photons is not "ponderable" mass
like that of matter.

Sheesh... Didn't you know that?

Sure. I also knew that dimensions can be curled up into tiny fucking
little balls and that one can use a wormhole (Thorne) or twisted light
(Mallett) to travel back in time and have sex with one's forebears.

Are you saying that your string is longer than Brian Greene's and
Michio Kaku's string? ahahaha... I've seen relativists compare their
relative ***** size before but I had never heard of anybody compare
their string lengths before. ahahaha...

And this has what to do with the Hubius Helix string concept?

I got your Hubius Helix hanging. ahahaha...

Absolutely nuttin'. I told you that you still don't "get it".

Of course I don't get it and I don't plan to. I got other plans.
Sorry.

Cool, man! Let's see your "bean" theory of an electron. We can start
simple. ;-)

Is your bean bigger than Hawking's atrophied bean? Somehow I doubt it.
ahahaha... AHAHAHA... ahahaha...
Making phun of "physicists" is so much phucking phun. ahahaha...

A single photon has no rest mass. A system of two or more photons,
such as that of "light" or that of an electromagnetic wave, can have rest
mass. In the center-of-momentum, the rest mass energy is equal to the
system's total energy. One cannot define a center-of-momentum for
a single photon. In the language of physics, "particle" doesn't imply
"mass".

[hanson]
Jako, it is good to have you back and it is interesting to see that
nobody responded to your statement, ... ahahahaha...
So, I wish you would elaborate on it because if a single photon
doesn't have rest mass but two or more do so, when being described
as a system, then where does that rest-mass of the rest-mass-energy
come from?... and what does this rest mass of the rest-mass-energy
represent?... especially if "mass" does not imply "particle" in the
language of physics.
hanson

Greetings hanson
"rest-mass" isn't necessarily associated with "matter". A diverging
light beam has rest mass, the center of which travels at less than the
speed of the photons that makeup the beam. There's no "matter'
there; no need to explain "where does the rest mass come from".
If the energy density of the diverging beam is E, then its momentum
density, p, is less than E / c. Explicitly,
p^2 = ( E / c )^2 - ( m c )^2
Where m is the beam's rest mass density. The beam's rest mass
density is invariant WRT observer reference frame.
The observer can overtake the beam's center-of-mass. He can travel
with it. Think about it.
