Earth is in fact falling towards the sun, very slowly but surely. Reversing that trajectory means that the earth would be moving away from the sun.

- ridiculous_fish 8y agoIf earth is falling towards the sun it is due to higher order effects, like friction or gravitational waves. It's not due to gravity itself, which is time symmetric.
- hermitdev 8y agoIf you reversed the trajectory, the earth would still be falling towards the sun, but reversed orbit. i.e. orbiting counterclockwise instead of clockwise from a fixed observation point.
