Given the fact that data is an electric circuit of ones and zeros, flowing at the speed of light, could we technically send information across time?

    I dont think it moves at the speed of light unless its using optical connections.

      Optic fibers normally have light moving inside them at something between 1/3 and 1/2 of the speed of light.

      And electric signals in network cables usually move at something between 1/5 and 1/3 of it.

        So neither i guess. It nakes sense as even fiber optic uses a medium to transmit the light.

      As I understand it, massless particles always have to move at the speed of light in the medium through which they’re moving. The catch is that it varies depending on the medium. The speed of light is only equal to c in a vacuum. Even in optical fibers, light speed is < c.

        If I remember correctly the only massless particles that travel through space are photons. Photons are what make up light so to say they travel at that speed is a little redundant.
