<i>does that really mean that space is really so constantly twisting and turning that SOL can&#x27;t be exceeded?</i><p>IANAP, but I&#x27;ve never read that space twists to prevent the SOL from being exceeded.  I think you&#x27;re thinking of time and mass.  It would require an infinite amount of time or infinite acceleration to for something to accelerate to the speed of light relative to something else.<p>Space is twisted by the presence of matter, and we call that gravity.<p><i>If it&#x27;s photons emitting from flashlights pointed in opposite directions relative to each other, then are they compressing space as they travel so as not to exceed the speed of light</i><p>No.  My understanding is that from the point of view of a photon time is completely stopped.  Nothing moves relative to it because of this.  Since nothing moves relative to it, nothing is exceeding the speed of light relative to it.
