It's a little frustrating following some of these arguments because I only seem to receive about 1/3 of the postings. Many I don't see until someone quotes them in their post.
If it were possible to travel just under the speed of light from Planet A to Planet B, wouldn't the distance travelled and the time taken both appear to shrink to near zero for the traveler? And ultimately, aren't all elapsed times zero and all points on top of each other for a photon?
Again, my apologies if I have missed what the point of this thread is.
Bob

As such, the t component cannot be zero in any frame. If it were
zero, it would mean that the two points are not different. It would
mean they are sitting on top of each other.
