gravity error

    in powder toy if you turn on radial gravity and make a solid mass it should simulate a planet. which means that if you made a hole all the way through the "planet" and droped dust particals in the whole it should fall all the way through the "planet", return to the hight you droped it on the other side of the "planet" and then fall back through the whole and since powder toy is a vacume with no friction or wind resistance this process should repeat itself untill you change something, since  the only force acting on the dust would be gravity, all due to the law of conservation of energy. currently in the game if you perform the experament i decribed the dust will just collect at the center of the "planet."

    well particles simulate speed loss over time, so i am assuming it is assumed there is some kind of gas in what you call "vacuum"

    okay, over time I might agree with that but if you perform this experament you will see that it dosent do what I say should happen even once.

    I don't get why people don't understand that The Powder Toy was never supposed to be realistic.

    And this "error" matters because.....?

     

    I don't see how "fixing" this makes anything easier or adds a whole new experince to TPT.Just because real life says it should happen doesn't mean it should happen in TPT.

    in vertical, the gravity source is at the bottom. in radial the gravity source is a point near or at the center. if stuff were to pass right through that then the vertical mode would also have to follow that rule- but you don't want the particles to be bouncing back up onto the screen!

    Unfortunately Powder Toy empty space is not a vacuum.

    Do any particles lose energy to drag in extreme negative pressure? (i.e. -256)
