Now heaven, though scientifically explained as a vacuum, still represent a puzzle. And there is no guarantee that the next generation will not see a completely different space. But there is a certain vision of the modern feature: at least on the scale of the solar system, we know some of the laws governing the functioning of space and planets located therein. Also, gradually changed our life. The modern man, which in a broader sense than five hundred years ago, there was a desire for knowledge. Many ordinary people far from science, eager to learn the secrets of the universe. That is why the game industry is focusing increasingly on virtual simulation of physical processes. Most of them, of course, relate to our earthly life. This is a battle simulator, family life, car racing history. These games are designed for people who are interested in reality or historical events. They just want to know in a virtual world that you can not know in real life.

Others - want to get closer to understanding the essence of the universe. It is the second category, there are games like Gravity. This game quickly conquered the world players. To play Gravity, have something to sense in physics. Of course, not all versions of the game are complex, there are those in which it is a simple variant of billiards, but the most interesting release - the ones in which you need to calculate the trajectory. On this page you will find both versions of the game. Try to calculate the correct flight path with one time! Try for free.
