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?

    Clarification: data can be sent at c, but electronic data can’t. Electrons have mass and can’t move at the speed of light; the electromagnetic waves they carry can move at the speed of light in the medium through which the electrons are conducted, which is still slower than c. Photons, on the other hand, can transmit optical data at c (which still doesn’t do anything unexpected with respect to time).

      From the photon’s perspective data arrives at it’s destination the same instant it is transmitted, but that’s true of all photons.

    Yes, you can make a post and then I can read it later. If you’re talking about reverse time like I read your post and then you make it, no. For that to happen, you’d need to send the data faster than the speed of light and our current understanding of physics deems that impossible.
