DA:
Of course gravity becomes weaker as one approaches the center of the earth. If the earth were hollow and an object were to be placed into the center of the hollow earth it would feel on gravity except related to gravitational anomalies (such as Mt. Everest), the moon, the sun, etc.
Why? Because the mass of the earth would be equally spread around them pulling equally in all directions.
would the planet be a stable body if the planet were hollow or donut shaped?
would it also have a donut shaped core?
would the gravities of each side pull or tug the hollow planet until it became a solid sphere?
when gasses are observed in space they do not form hollow or donut shaped bodies they form spherical bodies of gasses.
if you were to release thousands of beads inside the space station they would form a sphere of beads not a donut or a hollow body.
just like water that is released inside the station.
this I believe is due to the attraction of bodies to bodies because of gravity.
they would not line up and form a donut shaped body.
if gravity were weaker at the center of a body then a gas in near zero would form a hollow sphere because the gravity at (.5 radius the gas)
would be strongest.
the strongest gravity prevailing over the weakest
and the hollow would form.
but this does not occur.
everything points to a constant g.
nothing points to a variable g.
the constant is derived from the amount of mass a body has.
g is constant.
if the earths mass were the size of jupiter or the size of our sun or the size of a single atom the constant g (9.8 m/sec^2) would remain intact.
theres where I find your opinion to be wrong.
