OP I work in the film/media industry as a director of photography and the science of lighting scenes is truly fascinating. It mixes art and science together to really give you the emotion of the scene.
Theres so much you can do to light, its fucking crazy. If I want to raise the ambient light level of a room, I shoot a strong spot light straight up in the ceiling and bounce the light all over the room. The act of diffusing light is also incredible. Its amazing to see what happens to light when diffused by tracing paper, metal scrims, silk, or a white shirt.
Its also cool how you can tell how hot a light is depending on the color the burning filament (or fuel source) is. It works the same for the light emitted from stars. The bluer it is, the hotter.
Its also amazing how light bounces and gets absorbed. I use a white piece of cardboard when Im shooting outside to bounce sunlight off the white board and onto my subject. I can also use a flag (its a large square of black fabric) and angle it how I need to to absorb incoming light or make it "spill" softly.
Its fucking crazy, guys. Light is awesome, and only composed of three colors.

oh I know, photography is a hobby of mine and I know a little about cinematography too. Very cool what you can do with light if you know how to use it! The possibilities are endless, you can basically get whatever look you want with the right tools

Envix said: check this out. photons exist as the fastest speed there is. all other speeds are measured relative to it. what is speed? time. speed = time. a photon traveling at its normal pace (the speed of light) will have reached its destination the EXACT SAME INSTANT it left. departure and arrival happen at the same instant for a photon, no matter where it's traveling. to us, light may seem to travel for thousands and thousands of years even. but from the perspective of the light that's traveling that speed, time is not passing. all points exist simultaneously, all points in space and time, are here and now, when you are light
locality is not an issue if you're a photon. since no time passes, you basically exist as a reference-point for everything else that's ever happened in reference to light. so basically matter is just light energy condensed to a slower vibration, this is when time is created and things undergo process. time means process. time is a property of things which undergo process (matter and chemicals). process means waiting. light need not wait, because light is beyond time. what the hell do you have to wait for anyway, when you're traveling at the speed of light?
So from lights perspective time is stopped and it arrives instantly, and/or is in all destinations simultaneously? but from our perspective it's moving through space at the speed of light?
thats right! when we measure the speed of light, we get a measurement of light's speed in accordance with the physical universe. The physical universe is made up of many things which travel much much slower than light. light passes through much distance in space and time, through the vacuum of space, or the atmosphere of a planet. However, since everything moves at a speed relative to light (light is the fastest speed there is), light gives the illusion of having a speed limit to us. this is because we're moving so so slow, that we can even measure time itself and fit the speed of light into a category of it Quote:

So if lights speed is relative, then does that mean that our physical bodies cannot travel as fast as light?

remember that time is a property of things which undergo process. once you step out of the realm of process, you are basically traveling at light-speed (or, you've completed the process!)

imagine you could gain enough momentum to reach the speed of light
as you approach the speed of light, time would appear to slow down a bunch, but also your perspective of process would shift dramatically. right now you view process from the vantage point of your own speed. your own "processing speed". if you were to approach the speed of light, you would not be able to process the information properly unless your brain could also process information at the speed of light.
i think you have to take the limitations of human perception into consideration when trying to imagine different laws of physics that we're not normally accustomed to

ah makes sense, as you approach light speed time slows and you therefore are able to process things much faster than whats not moving at that speed.

i wonder if there are ways to get to light speed without physically moving
maybe if we could speed up the vibrational rate of all our individual atoms, we might have a shot

^^ yeah that explains the properties of light being a particle and a wave..
if you have the time tuff it and out and watch some of these videos.. It's free Stanford lecture for free!

I think light is energy
energy can move even in empty space or through matter
just like a plasma can
you can send a radiowave with the speed of light to the other end of the universe with a 9V battery, some copper wire(coil) and a contact the energy keeps flowing, nature doesn't like change, it will let it keep flowing
if matter can float freely in space, so can energy for energy is matter (e=mc**2)

^ light is energy!! and all energy is in the form of heat! that is why lasers can burn shit!
Heat is really interesting since it technically is energy!! That is how a lot of thermodynamics works and explains why processes undergo spontaneous bonding and reactions. Biology has used this for all of its processes!

I also have found it fascinating that an infinite amount of photons can be "fit" into a beam of light.

Really? You can truly fit an infinite amount of photons in the same space? Or is it only infinite like the beams just gets bigger? lol
How can they prove this?

another word for nature tries to balance itself
the universe and your psyche too
everything balances itself, atoms inside your body too, they're neutral charge all matter we see is neutral charge
if you send out matter in space, you get pushed the other direction by nature
if you send out a radiowave, nature will try to cancel it all the time (changing E and B field)
if you create a signal in a wire with a current, the current will keep flowing, or send back-emf if you stop the signal
if you send out energy/mass in space/on earth, the energy will keep flowing (inertia)

this is possible because photons have no mass. no mass = no space to take up

thats a better way of wording it. the universe likes balance, but the universe also favors change. change is what brought life to a molten-hot floating rock in space. change is what selectively adapted that life to evolve heightened forms of consciousness

A photon is everywhere in space, or where you measure it, depending on your view
when you view it, it is where you view it
but else it is everywhere in the universe at the same time
an infinite wave
it is still one, it is just spread out
or maybe I'm overlooking something?
