I viewed a lot of websites. Most says that there is no gravity in space. Is it true? Coz what i have in my head is that. earth, Sun, Moon and every otehr stars or planets all seems to follow thier path and keep themselves inside that path. Like cars on a traffic road stays in their own lanes. In many space or sci-fict movies, or even real, when there is no gravity - things tend to fly in all dirctions. But how come large objects like earth, sun seems to keep in thier own motion. Instead of flyin insto all dirctions. It is said that when a smaller subject is put nxt to a larger object with greater mass, the small object tend to be pulled into the larger object. And that is how us humans tend to be stuck onto earth.... not flying around. So, if earth, sun and moon.. or any other planets tend to follow thier own circular motion. Then there must be a gravity force or some sort of similar force acting on those large objects ( as in earth.sun.....etc). So where would the central gravity force be?
