Is it possible to figure the weight of the world?

The weight of an object is related to its mass which is the amount of matter packed into the space it occupies. It is mass which causes the pull of gravity and the weight of an object is the pull of gravity exerted upon it. This is all very complicated, but it is the reason why experts always talk about  the weight of the world as the mass of the world.

The mass of the world can be figured from its size and the power of its gravity. The answer, just as though it were a weight, is given in tons. The latest estimates on the mass of the earth can be written as 5,977 followed by 18 zeros. For all practical purposes, you can say that this is the weight of the world in tons.
