Thread: About Half of the Water You Drink is Older than the Sun

New research reveals that as much as one half of all of Earth’s current water supply is older than the Sun.

An international team of scientists led by Ilse Cleeves at the University of Michigan looked back into creation of Earth and our solar system to find out where all of the water came from.

Some scientists think Earth’s supply of life-sustaining H2O was the result of chemical reactions that took place as the Sun and solar system began forming some 4.6 billion years ago.

Others theorize that today’s water originated about a million years earlier in the cold recesses of interstellar space from a molecular cloud that later provided material to form the sun and planets.

To reach their findings, Cleeves and her colleagues simulated the chemistry of our solar system as it was forming and then compared the ratio of two slightly different types of water, one that was plain H2O and the other, ‘heavier type’, that had been enriched with deuterium – an isotope of the hydrogen molecule.

The researchers found that the water in Earth’s oceans as ice found in comets have a higher ratio of the ‘heavy water’ to the deuterium free water than the Sun contains.

I think PG tips tastes better with ancient pre-galactic heavy deuterium water!

I think the same can be said for the air we breathe.

nothing to worry here, I stopped drinking Chang a while back!

So what is the sell by date for?

There has been no appreciable " new " water on the planet since the last big asteroid collison 60 million years ago.

so my 70 years of rancid piss is going around again, enjoy,

There is plenty of lovely clean 100% pure fresh water.
Trouble is its all locked up in the ice caps.
I say we investigate melting it , so we can start using it .
who cares if the worlds coast level rises, change is interesting .

Why would an asteroid add water?

I wonder how many old grannies my glass of tap water has passed through in that time..?

All exothermic oxidation of hydrocarbons produces new water molecules by chemical reaction. Everything from coal fired power stations to a human brain burning glucose to a termite digesting cellulose.

Are you sure about this 100%, Blue?
Or, might you just be repeating what you have heard/read?
