@cmuratori "Reasonable if the aim is to get the bare minimum of an analogy across". Which is usually pop science's highest aim.
@cmuratori @hamishtodd1 That's where the parabola comes from. It's why (Newtonian) gravitational arcs are parabolas not, say, cubics.

@cmuratori It's the rotation that's cute here. It may not matter whether it's a quadratic or exponential curve.Thanks. Twitter will use this to make your timeline better. UndoUndo

@cmuratori (Portal could have exponential gravity and I reckon a similar phenomenon would be observed)Thanks. Twitter will use this to make your timeline better. UndoUndo

@cmuratori Looking back, it was my fault for being unclear. When I said "four half-parabolas" I wasn't saying portal teaches you that...Thanks. Twitter will use this to make your timeline better. UndoUndo

@cmuratori ...it's parabolas. I'm saying it lets you think about trajectories in this novel connected way. -
@hamishtodd1@cmuratori Portal is dumb. BOOM! :) - Show replies
