You can just tell this is going to end up like 20 pages long.

It'll probably turn out like the 0.99r = 1 thread.

No, where do humans come from?

nutrients and elements in the ground. So all you've done is transferred mass from the ground to 6billion humans. So the net weight is the same.

Does that actually gain mass. I thought it was just the energy used to perform a chemical reaction.

DIdn't think humans were made out of stuff from the ground :confused:

What a bout black holes? I heard they can suck energy in as well?

it is lighter because of all the holes we've dug in it and all the water we've drunk.

LMAO that made me laugh

But most of what we are made up of is stuff that was already on the planet except for sunlight which caused so much to 'grow'.

Well yeah, we eat other animals and plants to grow and breed, so it's not a massive increase, because a huge amount of what makes us, has come from the ground. But I would say on average the Earth has more weight on it now than it did when it was a newly formed planet, where we didn't have plants, animals, oceans and fatties.

Hang on what about all the crap we've fired into space and incinerated into the atmosphere?

WushuMaster · 16 Oct 2006 at 16:53

Surely 6 billion people dont just pop up. They only get there because they eat food that the earth produces and water that is already on earth??? :confused:

It's a bit harsh calling the Shuttle "crap" isn't it?

Thats one ugly pregnancy i've just pictured

Maybe, but what about all the satellites, space junk/monkeys we sent up?

and what about all the fossil fuels we've eradicated?

Shoseki · 16 Oct 2006 at 16:56

Does energy have mass? Because all the time the sun is shining, millions of photons of light are pounding the earth, being captured by photosynthsis etc etc. Am pretty sure there are experiments where an ion is split and releases energy, and this is calculated by the reduced "mass" of the components.

In which case, the earth is getting heavier every day.

But that's simply been turned into carbon particles and co2. So yet again the net weight is the same.

Compared to the amount of meteorites that have landed on Earth over the millions and millions of years, I think the stuff we've sent into space doesn't really compare.

DailyGeek said:

Good point, we've burnt quite a lot of it.

Well I guess that depends on whether you are including the atmosphere in the weighing of the earth

rather than just the planet itself.

I would say the atmosphere is an integral part of the planet.

And photons have no mass according to wikipedia.

The photon has zero invariant mass and travels at the constant speed c, the speed of light in empty space

I wouldn't (when it comes to weighing obviously, i'd like it for my ability to breathe)

But then I'm not a scientist.

If i weighed my shoe, i wouldn't weight it with my foot in it

bitslice · 16 Oct 2006 at 17:02

Apparently:
several tons of dust and micrometeorites hit Earth's atmosphere every day, adding up to 40,000 metric tons a year.

All the satellites the world has ever launched total about 17,500 tons of mass

Wrong analogy

Would you weigh your shoe with the shoe laces in or not?

But how much of the upper atmosphere do we lose from solar winds.

In fact, it was a really bad analogy, I wouldn't be weighing a shoe in the first place
