didn't bother reading the rest, its not getting heavier or lighter. objects in space are weightless. things only weigh something on earth
because of gravity, soooo 2 ways of thinking of it,
1) there is no gravity in space, so it has no weight
2) if you insist it does weigh something, it will weight equally in all directions, cancelling out, resulting in 0 gravity

The question shouldhave been -
Is the earths Mass increasing..
However the earth does have weight due to the fact that it sits within the suns gravitational fied and as
Weight = mass * gravitational field strenght
and the mass oth the earth is increasing it weight will also.

The Earth must be increasing in size or the stuff archaeologists dig up would still be on the top if it wasn't. What I want to know is who
buries all that stuff anyway?
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Yes, they are. Eventually we'll stop spinning, and then we're really boned 
Of course we'll be long gone by then...

am sure that the year is getting longer, In the Devonian Era i think it was something like 210 days long rather than 364 it is now.
As the Earth slows down than it will spiral in closer to the sun. Will take a long time to happen tho.
As for the Earth getting heavier/lighter i am sure that i read somewhere that approx 300 tonnes of space dust and metorites are scooped up every day
so i would say its getting heavier
