If the total human population grows at the current US natural population growth rate of 0.6% per annum then in 16000 years the mass of human beings will be larger than the mass of the Universe.

If it grows at the current Indian natural population growth rate of 1.5% then we have more like 6400 years.

I don't believe this. Show your working!

I'm skeptical as well.

Besides, won't the earth sink or something?

Let's say we have 6 billion people at an average 60 kilos = 360 billion kilos = 3.6 x 10^11 kilos.

1.006^16000 ~ 3.7x10^41

->

1.33x10^53 kilos

Come on, the universe has to be heavier than that.

Isn't the title of this thread an oxymoron?

Hmmm... it adds up. Mass of observable universe = 3 x 10^55 g

so what's the current weight of the people on the earth compared to the weight of the earth itself?

does lots of people living on the earth have a consequence for the earth's own orbit?

Ah, well, it ain't my problem.

you are born from dust and to dust you'll revert.
that's soil, dirt.
earth.

More people will not add any matter to the earth, they're just blobs of earth's own matter, which coalesce, trot around for a while and then disperse again.
If every people on earth would concentrate in Florida and sink to the bottom of the ocean, or get caught up by a tornado and be delivered on top of some plateau in the Andes, now THAT might have some slight influence on the angular momentum, I think...

btw, fyi, earth mass (http://nineplanets.org/earth.html) is almost 6 x10^24 kg
divide it by 6 x 10^9 people, we have now ~ 10^15kg earth mass available for each of us

ah yes, my cowie just came and explained that to me, i forgot about matter not being created and destroyed (barring some weird zero energy exception or something)

but i was thinking, in theory, the earth could gain matter because of photosynthesis and the harnessing of solar energy

or if a big rock hits us

I let it get to 16000 years because that's larger than even heavy estimates of the Universe.

If you had put the equivalent of 1 $ into a savings account in roman times, with 2 % interest, your heirs would now own the world's gdp - 3000 times over.

It's all so confusing.

I t couldn't really gain matter as growing plants use other forms of matter to grow (Nitrogen, CO2 etc.)
However the Earth can become more "Energetic" and all other factors aside this will ultimately cause the death of the Earth

Also known as "Entropy Death" (one of the names bandied around for a band at Uni!)

You should call your new death metal band Entropy Death.

Nills Lagerbaak

Ah, that would be the same band who are working on my "Next Rock Epic"

It all fits together perfectly.

Funko

That shows how perfect it is.

Any snifters of bands in bristol or is it still too early?

Yeah, had a quick look at that.....guitarists seem to be a dime a dozen. One of my friends did mention something about a pioneering punk/metal band looking for a guitarist......may have to pursue that one!

Yeah, they totally are. You need to play drums. :)

Anyway, get the band sorted so we can do this Pirates/Rebus/Müf/Your band gig booked. :)

We need a drummer after Saturday. :(

Earth gains matter every day. With some good Google-fu, you should be able to turn up the best estimate. The source of the matter is... the sky is falling. Lots of small rocks and small ice pebbles. Isn't that nice?

Then, there is the solar winds. That's actual particles. Most get directed away from earth. But some bit of those particles get channeled down to the earth at the poles.

Earth also loses some matter every day, but we don't have good estimates. Most of this lost matter is highly excited hydrogen escaping. This hydrogen is primarily from the breaking down of water (H2O) by natural processes. ie, The earth is farting away its water.

(Now, this is a true PH.)
