Equation from Visitor Event

There was an equation in Stage 1 of the Visitor event. Can someone explain to me how this works?

Seems ridiculous to bring quantum physics in a game where time travel is trivial (Neo Tokyo/City) but it seemed like an interesting topic for the Rubik's Cube.

 Spoiler

I understand it's an equation about time dilation but that would imply either the player or Dr. Bing moved at fast speeds? Further, since the world itself is projected onto a single plane (the projection can be confirmed by the existence of both a world map and an atmosphere/outer space), wouldn't time be a constant for everyone in-game? I thought "magic" was the explanation for in-game physics/biology/etc.
