Using
very simple math The Newton's Law of Gravitation tells us that the
attraction of stuff to other stuff changes inversely as the square
of the distance between them and varies in direct proportion to the
product of there masses. Now the big question is this --What is the
speed of gravity? Newton's theory of gravity states that all masses
pull all other masses instantaneously. However, in 1905 Einstein published
his famous theory of special relativity which stated that the speed
of light is the fastest speed any energy can go -- 299,792 km/sec
is tops. So who is right? Is it Einstein or Newton?
If
you were to carry the weight of the world on your shoulders, how heavy
would it be?
British physicist C. V. Boys calculated the weight of the world to
be 6.10**24 kilograms.
While
tethered to the terrestrial jugglers are prone to test finer points
of
the laws of gravitation on a daily basis.
