There will be no new elements to find in space, .

The list of elements formed in supernova is limited as well as materials and elements formed in geological events (I would imagine).

I dont agree with this, I highly doubt every single element ever formed in the entire vast universe happened to land on this little speck on nothing we call earth.

The model of the universe does not even work if the elements we had on earth and can see were everything in the universe. Estimates of the amount of matter present in galaxies, based on gravitational effects, consistently suggest that there is far more matter than is directly observable.

Scientist sometimes call this dark matter but its really just a term of expressions of our ignorance of whats in the universe. Astronomers don't know what it is, but they know it makes up about 23 percent of the universe.

The universe is far too big and the amount humans have explored far too small to rule out anything yet.

Some elements such as the lanthinides and actenides are synthetic, like Plutonium, and as well as those listed afterwards. Most of the recently discovered elements only last for days, minutes, seconds and some for just a fraction of the second and have no real economic use.

The amount of elements on the peroiodic table formed in supernova (or stars) goes up to iron. Everything else is a process of geology. There are structures and molecules in space which humans can only observe from these points, but harvesting these would be like harvesting gold in the ocean. It is far too dense to do so. Such as the structures of carbon that form around stars and cause a haze like distortion. These were then imitated to form fullerenes, but I would be doubtful if you could find a naturally occuring fullerene outside earth.

I think one of the best reasons in the future to inhabit space will be mining. There is a platinum asteroid that is worth about $5 trillion or $6 trillion, as well as an asteroid that has more steel in it than all the iron on Earth.

Gold, Platinum, Iron , Nickel you name it its all out there in spades. Its access to near infinite raw materials.

As we get better tech to get into space cheaper and Earth's resources cant handle peoples needs space mining will take off.

Don't you mean 'there is more iron-oxide on the asteroid than iron in steel on earth'?.

I think you have to ask Richard Godwin one of the Board of Directors for the National Space Society (NSS) if he meant iron-oxide on a asteroid than iron in steel on earth.

Heres the exact qoute he said

Godwin said there is a platinum asteroid that is worth about $5 trillion or $6 trillion, as well as an asteroid that has more steel in it than all the iron on Earth.

If you think you have to correct what he said perhaps you should contact him.

What I find wrong about the quote is that steel is an alloy of iron, some coke(carbon) and limestone and a few others. So I think it would be particularly hard to state that steel will be found on an asteroid and compare that amount of steel (an iron alloy) to an amount of iron. I think it is actually a misquote by the author and not Godwin as it does not appear in quotations.

does it really matter?

why is it nessecary to pick and poke like that.

every one knows what he ment.
