| Every object in the Universe attracts
every other object in the universe. This invisible force for masses to move toward
each other is called Gravity. When you weight yourself, your weight may be around 30kg
to maybe 50kg because of Gravity. Your weight is the result from the product of the force of gravity and
the mass of you.
Why two masses separated in space have a
gravitational attraction to one another remains unknown, despite
much research and various theories. These theories are listed on the
left: Newton, Einstein,
and Quantum. |
