Is this correct, I heard it as more like a hundred tons a day,so whats the math on the increase even though I understand
if this is true why doesnt earths gravuty increase by a small
amount over millions of years of collecting more matter that
has mass.
it would take millions of years to to change the slightest but
it should increase wrt time right
Less than 1 part in 10^8 change in G*M of the Earth in 2.2
billion years (tidal rhythmites, lunar period).
Why do you think this is important? We can't even establish G to
six sig figs, when we've got sqrt(G*M) of the Sun down to 11 sig
figs.
Just because you weigh more on the scale each day, doens't mean
it isn't what / how-much you are eating... ;>)

amount of material is added to the mass of the earth each year. The
sun also distributes some part of its mass, in the from of particles,
to the space around it, and 2.1kg of this amount is added to the earth
per second. And also, the earth receives 14-ton cosmic dust from the
space around. So we see that, in fact, the earth receives mass from
the space surrounding it.
But what about the increase of earth's mass inside it? Assume that we
are pumping a ball by a pump. In fact we increase the air inside the
ball. Because the ball's shell has a certain volume, but if we want to
pump it very much, the additional air will exit from its hole or it
will be torn up and the air will exit. The earth's sell has a certain
volume like the ball, and if the mass inside increase, the additional
materials will exit through a hole or crack from the inside of the
earth. Does such an action occur in reality? We know about the outflow
of molten materials from the inside of the earth to its surface. These
materials exit either from the volcano, which are like holes on the
earth's shell, or through the long cracks, which are under the oceans.
So, in fact, we observe the increase of the earth's mass. So we can
accept the increase of the gravity with high degree of insurance,but
whats offset by earths loosing maas by giving off gasses and other
particles that escape earths gravity and offset the over all ingestion
off mass.
