    Ok, firstly I’m not very smart. Secondly I don’t understand the meme AND don’t understand the explanations in the comments.
    Can anyone actually dumb it down so a stupid person like me can understand it?

      you and two friends, Al and Be, are outside at night time. Al has a flashlight and flashes it at you and Be. Be is 20 feet away from Al, and you’re 20 feet behind Be.

            20ft         20ft
      Al..........Be...........you
             r1          r2
      

      The photons from the light Al has hits Be first, so he sees it first. it took .03 seconds(r1) to reach Be.

      After that, the photons hit you and you can see it. it took .03 seconds(r2) to reach you from Be.

      They were both .03 seconds because you are equally apart and the speed of light is finite.

      so, how long did it take the light to reach you from AI?

        I’m not following how this explanation is supposed to help with their question. Like, what are you trying to get at here?
