help me lrn2physics

Hey /sci/,

How the hell can something be massless? Someone told me that light is a massless energy particle or some shit like that but that can't be possible because in order for something to actually exist, it must be made of something, and that something has to have mass, regardless of how minute it is right? Or is this correct since light is suppose to have duality? Please edumacate me.

c increases if space expands.

>>41

Which means that the photon would increase its velocity, i.e. accelerate, right?

lrn2GR; spacetime is always locally lorentzian, there is no c increasing or decreasing

>>40
lol, wtf? who cares if photons accelerate or not. Like it f'ing matters anyway, amirite? Talking about photons...how about women? I would like to see what a woman does the first time I massage her thigh. The look in her eyes, her surprise, her breathing, what does her breath smell like, her face blushing, her soft hair against my face...hmmm, now that's something worth finding out about, amirite?

lol, stop it. Photons can accelerate or decelerate depending upon what pushes and draws the photon. Find out that info and you can control the flow of photonic energy how you want. Hell, you might even be able to project a new information beam faster and further into space depending upon how you use it. I hope you understand what I mean by push and draw...please tell me you know this function about nature...o.o

You're nuts.

Photons interact only with leptons, quarks, and W bosons (and gravitons, but standard model can't account for gravity).  None of these things can accelerate a photon in the classical sense.  I think the most they can do is absorb and emit photons.

hmm, thanks for noticing. You're not so bad there yourself.

the particles of light are called photons & they are massless. They are effected by gravity in the exact same way as everything else. gravity pulls on the photons because they have momentum. thing can exist even if they don't have mass. mass is caused by the particles interaction with the higgs field. think if it like this. when you move your hand through water the water impedes the motion. massive particle interact more strongly then light particles so it takes more force to accelerate them.


the duality you are mentioned is the wave particle duality. which is that light acts like both a particle & a wave. in that it will interfere with itself & that it comes in discrete packets of energy

redshift?

...okay fellas, what happens when you apply all energy in one direction, the path of each particular energy's least resistance? I use this function to achieve my goals, though I use the opposite also, learn of each, divide and utilize each flow for the prior statement. I believe this is knowing God to be like God. But that's just me, lol.

A guy named Albert told me once that Mass and Energy are the same.

He mumbled something about the equation E=MC^2

Where:

E= Energy
M= Mass
C= The light of speed in nothingness(vacuum)
