    The speed of light being finite has been settled for three centuries.

      Wrong if you’re a photon. No time will pass as you cross the universe

        Dividing by zero equals undefined, not infinite.

          You’re assuming there’s no alternative means of defining the formula, such as a contraction of length of the distance to the destination to zero which puts the experienced travel time at zero, which does not require you to divide by zero

              Look if you’ve never seen formulas where the physics is remains consistent as you cross by a division of zero before (such as a ton of differentials in thermodynamics where you simply substitute the term at that point) then maybe try again

              I know there’s a reflexive instinct to discard any formula producing division by zero, but if the extrapolation of the graph make sense without breaking any physics maybe it’s correct

              And aside from all that, something for which time is undefined obviously don’t experience the passing of time

                Do not be so open-minded that your brains fall out.

                  Maybe if it falls out, we can replace it.
