Yes and we should consider every successfully landed
grain of space dust as a meteor. Hmm... I think in time range of cca 4.5 billion years it should be quite a decent increase.
That's my little pseudo-scientific addition to this debate.
Now let's talk about astrology and psychotronics! \o/
But most of the meteor, and a bit of the planet, get converted into energy on impact, so wouldn't there actually be a net loss of some ridiculously small amount?
Also, I was giving some thought to the whole continents recurving to fit the new circumference and that's where mountains come from bit of this crazy theory last night, if that were true wouldn't the average height of mountains be mathematically predictable? I don't know how to set up the equation, or what the exact variables are, but given a crust thickness of ten miles (his number) and the degrees of arc that a continent took up at the tiny Earth stage, and the degrees of arc at current Earth size, and the width of the actual mountain ranges in a given continent, you'd end up with an average height of x, or somesuch, wouldn't you? It's a simple matter of plugging in the equation and seeing if reality matches. I'd certainly be more intrigued if our mountain ranges' heights actually came out what they are that way, but I'd bet dollars to dogshit that they don't.

What? Are these anti-matter meteors?

What I know is that when I die, my body turns into dust and after some time my dust turns into atoms and one day those atoms will form a new star. Or a planet. Or something.
So the Earth and probably part of the universe must be made of dead people.

The
mass of Earth increases with every meteor that successfully enters the atmosphere and lands. I can't remember if it's a significant increase, but there you are.
If it would be significant increase - an even more significant decrease would follow.
BOOM!

I remember a figure of 3 or 4 metric tons of space rocks/dust dumping on earth per year. It would take very many years for any change to be noticeable.

Then there are bolides that can end it all in two days. As for me, just thinking about Earth as a giant rock hauling ass through space filled with other big ass rocks puts a lot of things in more humble perspectives.

Yup. Our entire species could be annihilated by a random collision with a big rock, giving us a big fat zero for our total value and, for that matter, the value of our world in the big scheme of things.

You want end-of-the-world scenarios? (

bigger more ludicrous than others).

Are you sorry that one such rock wiped out dinosaurs?
Don't worry about future the planet after such collision. It will recover and eventually give chance to
new species, better adapted to new environmental conditions.
