What is Gravity? Information on what some people think
gravity really is.
Scientists still have a tough time
understanding what this force is. This remains one of the greatest challenges of 21st
Century science.
Here is the mainstream view
of what gravity is. After we reveal some sources of alternate views of what gravity is.
Gravity is a force pulling together all matter (which is anything you can physically
touch). The more matter, the more gravity, so things that have a lot of matter such as
planets and moons and stars pull more strongly.
Mass is how we measure the amount of matter in something. The more massive something
is, the more of a gravitational pull it exerts. As we walk on the surface of the Earth, it
pulls on us, and we pull back. But since the Earth is so much more massive than we are,
the pull from us is not strong enough to move the Earth, while the pull from the Earth can
make us fall flat on our faces.
In addition to depending on the amount of mass, gravity also depends on how far you are
from something. This is why we are stuck to the surface of the Earth instead of being
pulled off into the Sun, which has many more times the gravity of the Earth.
Here is our favourite alternate view of what
gravity is.
