Planetary System
To Travel to other planets you either have to have a space ship or Instant Transmission. It takes one day to reach another planet in your solar system. It takes two days to leave your solar system and one extra day to reach a planet there. Using Booster you can make the time less than that. Also the Gravity multplies how much you get from training.
(Example on how to calculate gravity training)10(your normal gain) x 100(gravity)= 1000; 1000/2=500; 500+10(Your normal gain)=510(Your new gain)
