If I have a flashlight and the light travels at the speed of light (obviously) and I start moving at 10 m/s towards an observer with the flashlight pointed towards the observer, the light is traveling at c + 10 m/s towards the observer

Prove me wrong /sci/

Here's what happens in your example: beaming. The observer will receive light as if it was travelling at c, but maybe slightly more blue shifted that expected.

>> No.8664157

>>8664081
So what you're saying is that the color is shifted because it is traveling faster than expected
i.e. Faster than the speed of light

>> No.8664165

>>8664157

The light shifts color depending on the relative velocity of the source and observer because light always travels with velocity c.

>> No.8664649

>>8664201
Well sound doesn't work that way because sound is dependent on air molecules bouncing off eachother which usually only happens at the speed of sound
But light is a massless (basically) wave that propagates at c plus whatever speed it's being produced from. Therefore light can travel faster than the speed of light

>> No.8664652

this is all too weird

so light just adjusts to stay always at c whatever changes around it? like it has consciousness?

how do telescopes even work?

>> No.8664682

If a black hole can pull light backwards at the speed of light while the light is moving forwards at the speed of light, then it creates a standing wave which is moving at 0m/s. So intuitively we should say the opposite is true; a force can move light along its path which causes it to travel faster than the speed of light

No troll, not like it has consciousness. Its a law of the universe. Massless particles (or waves) always travel at c, its an inherent property of having no mass. Just like how particles with mass have gravity, they dont consciously decide to attract other particles with mass, it just how the universe works. Telescopes work by magnifying part of a distant object many many times by using a mirror or lense much larger than our retina to display an image to be read by our retina. The telescope sees the light as it was however many light years away the oject that is reflecting/emmiting that light is. Any more retarded bait?

>> No.8664787

>>8664682
Please tell me this is bait. A black hole is pulling space time (the medium through which light travels) into it faster than the speed of light. A flashlight moving forward is not the same thing, since the wave medium is not moving the light still travels at c.

>> No.8664797

>>8663950

The speed of light is absolute.

Thats meen that speed of the light is the same for all systems of reference.

If you run with the flashlight the light is traveling at same velocity as when you were standing.

There is no known limit to what speed the medium which light travels through can move, just anything within that medium. You must be trolling if you claim to actually think your idea holds any merit. Its like 5 year old logic, you arent even the first person to post this thread and be shot down by facts only to continuously deny said facts.

c = constant.

So if you go 99.9 of c and have lights on, that light is still going c speed, not c + 99.9 c
