One feature I feel TPT has been lacking for too long it the effect black holes and theoretic white holes would have on photons. When photons pass nearby black holes they should bend/warp and the speed of which the photons warp should increase/decrease when the distance to the black holes is decreased/increased and white holes should do the exact opposite. Just a thought. I don't know if it would be possible to implement but it would indeed be a great feature.
Thanks, glad it's getting feedback this fast:) I hope it will be implemented soon although I think it might cause some problems with lag, but then again TPT should have multi core support:D
It will not be possible because BHOL and WHOL use pressure to attract and repel particles and photons are not affected by pressure. To change this would mean that photons would be affected by other large amounts of pressure aswell like PLUT reacting.
Edit: Just re-read your first post. Speeding up and slowing down 'could' be possible. Could.
Not possible. The math involved is hilarious, it isn't going to happen. The only other way would be just to make photons subject to pressure and velocity like every other particle, but that would involve inertia @_@
