this is new to me:
Objects move in spacetime at the speed of light. A stationary object isn’t moving through space at all, moving through time at the speed of light.
an object moving through space at the speed of light has no speed to move through time
@totheralistair Although… it seems to me that *nothing* is stationary through space. Everything is on an orbital path around something, one way or another, and also part of the expanding universe.

@Sarandipt thank you - hmmm, so, relative to which frame are we measuring those two axes then? i'm pretty sure I'll not work this out in my lifetime ; )
