How did we determined the speed of light in vacuum ?
Since photons are particles,
where there is light it is not vacuum right?

I like this thread
I would like to know how ppl measured the speed of light in the first place
Oliver Phillips
shoot 1 photon in a vacuum.
measure its speed
?????
Kayden Butler
maybe they have to touch other particles for it to count as not a vacuum
Julian Gomez
vacuum immediately not being vaccum due to there being a fuckhuge orb or trion-re or solid or whatever a photon is that creates pressure, pressure waves, gravity, etc.
Not vaccum.

Go nuts OP
(for reference, I googled 'how is the speed of light measured' - I suggest this as a first-line approach to problem solving in future)

Op here. My point find out if as think, it is stupid to speak speed of light in vacuum, sincères if there is light it is not vacuum
Leo Allen
I mean, I suppose that's not inaccurate, but in this context 'vacuum' means 'space not occupied by matter'.
Matter that lets light pass through it causes the light to slow down due (more or less) to the light's interactions with the stationary charges (protons and electrons) that exist in that matter. This means that light in matter travels at less than 'c', sometimes a lot less. However, when light is travelling through space with no charges in it then it moves at the maximum possible speed c, and this is called the 'speed of light'.

that's like saying if light is in air then it's not air anymore
