Causality is overrated. Iâd be ok if we broke it.

You canât go faster than light because time and space are basically the same thing, and youâre always moving through both of them together at a constant rate.
When you stand still, you move only through time, at the top speed of one second per second.
When you start moving through space, your speed doesnât change, only your direction. The faster you move through space, the slower you move through time.
At light speed, youâre moving only through space. Your movement through time is zero, so time stops for you.
Going faster through space would mean going back in time, which would break causality.

What would we replace it with? The raw chaos of the universe in its unformed state?

But Causality isnât OK with that.

To be fair, what even is âstanding stillâ? Iâm sitting in a chair in a spaceship made out of silica, metal, gasses, and water traveling around 220km/s relative to Sagittarius A.

Itâs always in relation to a frame of reference.
Compared to earth, youâre standing still, so your time passes at the same rate as earth time.
Compared to Sagittarius A, youâre moving through space, so your time passes slower than that of Sagittarius A.
