![]() But it's not just furniture and the like that would start to float. ![]() Everything not stuck in place would suddenly have no reason to stay down, it would start floating. We depend on gravity to hold so many things down - cars, people, furniture, pencils and papers on your desk, and so on. This would turn out to be a pretty bad day. It is only when you get an gigantic number of atoms together, as in the case of the planet Earth, that the force of gravitational attraction is significant.īut let's ignore the physics and imagine that, one day, the planet's gravity turned off, and suddenly there was no force of gravity on planet Earth. If you use two massive pieces of lead and some amazingly precise instruments, you can actually measure an infinitesimal attraction between them. There will be an incredibly slight gravitational attraction between the atoms in those two golf balls. Let's say you take two golf balls and place them on a table. Gravity is an attractive force between any two atoms. If the Earth's gravity were ever to change significantly, it would have a huge effect on nearly everything because so many things are designed around the current state of gravity.īefore looking at changes in gravity however, it is helpful to first understand what gravity is. And there are two things about it that we take for granted: the fact that it is always there, and the fact that it never changes. Gravity is one of those things we take completely for granted.
