Light is moving so much faster. In the same two seconds it crosses a much larger distance in space. The line is only straight in spacetime, not in space.

- Ancapistani 6y agoIf I’m understanding, a theoretical ball thrown at 1c would follow the same path as a photon?
- Smaug123 6y agoYes, although you can't actually get anything with mass to travel at 1c (subject to our current understanding of physics).
- Ancapistani 6y agoAs I understand it, the only thing that can travel at c are: * photons * spherical, massless cows in a vacuum
- lostmsu 6y agoNot sure about cows. I bet a thing traveling at c might not exactly have 3 spatial dimensions.
- rawoke083600 6y agoAgreed ! The "spherical cow", has to first become a circular cow /s
- lovegoblin 6y agoAnything massless travels at c, not just photons.
