While I understand the search for extraterrestrial life is a delicate and tough one...

I also understand the need to understand what's around us, before we go off on crazy tangents...

That being said...

It's so funny everyone's still concerned with the Goldilocks zone, when it's been shown that life can adapt to some of the most harshest conditions, and it's a certainty that non-carbon based lifeforms who do not require water are certainly "out there."

Typical limited thinking from a sub-optimal, carbon entity.

Apparently they don't understand Post-Normal Science. They need to torture the data to fit the agenda, not actually hope to find supporting data... such amateurs

So true, it's likely the Higgs-Boson does not exist. Alas, if you need funding...keep finding "stuff." Or just hold back everything you've found until now, then slowly start the trickle of information to gain funds.

Galaxy Hosts 100 Billion Planets, in New Estimate

http://online.wsj.com/article/SB1000142 ... TopStories

Astronomers said Wednesday that each of the 100 billion stars in the Milky Way probably has at least one companion planet, on average, adding credence to the notion that planets are as common in the cosmos as grains of sand on the beach.

So humangous beeg...

So humangous beeg...

haha. I felt the same way as Bryz when I first heard about the Hubble Deep Field. If our galaxy (Milky Way) has a billion planets, and the Hubble Deep Field captured at least 3000 galaxies in a tiny section of the sky, then the amount of planets out there is mind boggling.

British scientists have discovered a "treasure trove" of lost fossils, some collected by Charles Darwin more than 150 years ago.

The fossils were found quite by chance, the Royal Holloway University of London said in a news release Tuesday. They were in a dusty old cabinet at the British Geological Survey, labelled "unregistered fossil plants."

"I can't resist a mystery, so I pulled one open," Dr. Howard Falcon-Lang said. "What I found inside made my jaw drop."

The collection consists of hundreds of "beautiful glass slides" made by polishing fossilized plants into thin translucent sheets so they can be examined under a microscope.

"Almost the first slide I picked up was labelled 'C. Darwin Esq,'" Falcon-Lang said. It turned out to be a piece of fossil wood collected by the famed naturalist during his 1834 voyage — the expedition that led him to formulate his theory of evolution.

Someone read the Cracked article today

Cool idea, but you cannot compress liquids. How much oxygen is in one of those tanks of liquid?

i beg to differ...

a lot.

and this.

I'm taking about practicality c2i, in that there would be little gain , plus you'd probably instantly freeze your throat and lungs

[PensFanInDC]

I thought hydraulic theory is based on liquids not being able to be compressed. I really know nothing on the subject outside of brakes on a vehicle so please enlighten me.

Do Invisible Galaxies Swirl Around the Milky Way?

According to cosmological theory, says MIT astrophysicist Simona Vegetti, "there should be thousands of dwarf galaxies in the Local Group." That's because the earliest days of the cosmos were not a tidy time, and after the big galaxies came into being, a lot of debris ought to have been left behind — "debris," in this case, meaning little galaxies made partly of what's known as cold dark matter. The fact that we don't see the galaxies, she says, is due to one of three things: Either they're simply too faint to detect, or there's something unusual about the local cosmic neighborhood that would explain why it departs from the larger rule. Or — and this is the troubling alternative — maybe the theory itself, which has been generally accepted for the past 30 years or so, is fundamentally wrong in some way.

The liquid probably has a very high heat capacity. Meaning it will probably stay above water temperature for an extended period of time.

[viva la ben]

Well a typical scuba tank carries 80 cubic feet of oxygen in a small 2-3 cubic feet of space.

How much space do you conserve by compressing liquid? It's negligible.

okay, i actually read the article and have a better idea of how this works now. the oxygen itself is not liquid, it's dissolved, so it's not super cold and wouldn't freeze your throat or lungs. It's similar to how fish breath oxygen out of the water. They're not taking in liquid oxygen, just dissolved oxygen. The problem is humans/mammals do not have the ability to get enough oxygen out of the water to survive by breathing it in. Apparently they can from these PFCs. It's a neat idea, but my only question is how do you get the PFC out after you're done swimming?

This is what confused me most.

lol...i'd assume they would have a more sophisticated way to do it than that...
