average distance from the surface of earth to the moon = 384400km
Speed of light in a vacuum = 299 792 458 m / s
time taken to travel at the SOL to the moon = 3.844*10^8 / 2.998*10^8 = 1.282 seconds
time of travel in this GIF = about 1.3 seconds
the GIF is correct on the amount of time taken, stop complaining.

SOL = source of light or is it Sol the sun.

Just wondering, Sir not judging or ridiculing.

SOL = Speed Of Light...

aahhhh okay thank you sir. have a great day

just wondering, what is the speed of light when it's not in a vacuum? Is it very different?
User avatar #49 to #44 - techketzer (01/28/2013) [-]
Depending on the medium, the speed of light can vary greatly.

"Denser media, such as water,[57] glass,[58] and diamond,[59] have refractive indexes of around 1.3, 1.5 and 2.4, respectively, for visible light. In exotic materials like Bose–Einstein condensates near absolute zero, the effective speed of light may be only a few meters per second."

Somehow my explanation was deleted.

When light "collides" into matter, it is absorbed and re-emitted. That process takes time to happen, which technically does not slow the speed of light itself, but pauses its travel and actually existence altogether.
That is called optical density.

It's very practical to treat such optical dense objects as if light slows down inside them (if you classically think of speed = distance / time, then in a sense it actually does).
Common glass reduced speed of light by about a third, while a germanium lens decreases it to a quarter, iirc.

I can't learn **** from wikipedia haha, so light travels faster through the air than it would in water? Because water is denser than the particles in the air, therefore denser, therefore will travel slower in water?

It does not seem all that fast when put in to perspective

I don't think you realise just how far away the moon actually is.. Please refer to the comment below and then change your perspective.

dat slow internet. GIF took a minute to load :P

If you really took that trip at the speed of light, you would see everything fade to red as you accelerated, and then see only blackness out the back of your spaceship. If you looked out the front of your spaceship, you would see nothing but a bright white light, the cosmic background radiation blue-shifted to visibility.
Physics is fun!
User avatar #52 to #32 - rabaneristo (01/28/2013) [-]
Actually, no. Because the light adapt itself to your speed. No matter your speed, light is always 300k Km/s faster. But I can see your point.
User avatar #61 to #52 - guitarguise (01/28/2013) [-]
you're wrong. Light does not adapt itself to the relative speed of the observer. Red Shift. look it up.

If I'm traveling the sped of light away from the Earth, then the light that is bouncing off of the surface of the Earth is traveling towards me at the same speed that I am traveling away from it. So my retinas will not be stimulated by them because they never reach my retinas. So at first the light that I was perceiving begins to fade (red shift). Then once I reach the speed of light, all I see is black in the center because no photons are reaching my fovea.

I'm pretty sure if you travelled the speed of light then you'd be breaking a fundamental law of physics, so what would happened is undefined.

Well, thats what EInstein would have said.. if you dont speak german: If you travel with the speed of light, time would stop, so this trip would have taken no time. you wouldnt see anything

The earth looks a lot smaller from the surface of the moon...
#78 to #18 - jeppetp (02/02/2013) [-]
And by the way, traveling at the speed of light backwards would just leave you with the exact same picture all the way through, until you slowed down...

NO NO NO! Light speed is too slow!

We're gonna have to go right to....LUDICROUS SPEED!

I'm pretty sure the speed of light is waaaaaaaaaaaaay faster
#3 to #1 - anon (01/27/2013) [-]
it takes 1.3 seconds for light to travel from earth to moon... so I'd say it's not that fast.

Distance between earth and moon = 384 400 km or 384 400 000m

Speed of light = 299 792 458 m/s

Therefore: 384.4 x 10^6 / 299.7 x 10^6 = 1.2823 seconds
This gif took 1.3 seconds when I timed it with my phone.

Other than the fact this gif ignores the major laws of physics (such as field of vision not expanding due to light from behind reaching you, everything remained the same colour, not fading and becoming red shifted during the journey) this gif still is accurate for the time it took on the journey.

the conversion between km and m is 10^3 not 10.
User avatar #29 to #21 - jinxter (01/28/2013) [-]
..Yeah i meant 299,792,458 m/s rounded to 300,000,000..... just wrote it wrong.

Watch Star Trek: First Contact. The Speed of light is pretty much that fast.
User avatar #6 to #1 - ojenais (01/27/2013) [-]
light actually takes 1,28 seconds to travel from the earth to the moon, so this is pretty accurate

The white circle is travelling at the speed of light from earth. You can see the moon on the left of the gif.

MFW these butthurt "scientists" are thumbing me down

no one cares if you know what the speed of light is.
User avatar #72 - drulludanni (01/28/2013) [-]
except you wouldnt have seen **** cause you were moving as fast as the light that came from earth
User avatar #45 - adambubba (01/28/2013) [-]
actually quite faster than the speed of light...
