Ok, being a scuba diver myself I should have been more precise, I was thinking of a planetary atmosphere not controlled conditions but you have answered that as well. I was thinking of a planet with a 10 bar atmosphere, I wonder if lower oxygen levels and more neon or helium would help but it would still have to have nitrogen some CO2 at 2 gees helium should be stable in an atmosphere but would hydrogen? That would throw a wrench into the whole idea...

If this experiment is carried out to it's conclusion the salted water should start to evaporate slower as the concentration of salts build up. Your result would depend on how much salt was in the water as well, enough salt and it can actually pull water out of the air if the humidity is high enough...

How much pressure can a human live at without ill effects?

I am very impressed! I'll try to listen on my stereo later but ti was very nice even on my computers crummy speaker! again great music!

It's safe, part of standard diagnostics as much as x rays or ct scans...

Very exciting time to be alive, I would venture a guess that this planet is more like venus than earth due to it's mass and closeness to its primary, but you never know!

I understand your point but who is to say that dinosaurs wouldn't have evolved intelligence? They did seem to be going toward bigger brains and birds which are dinosaurs display considerable intelligence with their small brains. I don't see why mammal brains would be the only brains to develop technology...

Can you show the universe was created? Calling the universe creation begs the question of a creator, if we call it reality does it require a realtor? The assumption there was a creator is flawed, you really need to show evidence for this "creator" and there are theories that go back to before the big bang https://en.wikipedia.org/wiki/Ekpyrotic_universeso your assumtion of either or does not hold up to scrutiny...

You ideas fail here to begin with: This is not in anyway similar to what the current scientific consensus holds to be evidently true.. The big bang was not an explosion in space, it was the expansion of space time. The Earth did not exist then, and wouldn't for another 10 billion years at least. The big bang did not create the chemical s of life such chemicals were forged in the heart of stars, the big bang only produced hydrogen and helium with a tiny amount of lithium.

What a saw is truly impossible to describe, I don't have a frame of reference to describe it...

I thin posts #8 and #12 pretty much sums it up...

When you consider we have only searched something like 1% of our own galaxy for earth like planets and we have found several, the prospects for life would seem to grow to some extent. Considering that we have to be searching for a civilization that is intentionally sending out signals. the old adage of detecting leaking EM radiation like TV or radio is simply not going to happen. The Earth's unintentional leakage is thought to be absorbed long before it get as far as the nearest star. Taking that into consideration the galaxy could be a very crowded place but unless they are intentionally sending a signal in our direction we would not detect them. SETI has at last on one occasion detected a signal that resembled military radar coming from deeper in the galaxy but it didn't repeat. I think it's justified to look and the idea of detecting Lasers is a very good idea but the galaxy is a big place and a civilization could rise and fall on the other side of the galaxy and it would 100,000 years before we could detect any signal they broadcasted... Why would you consider plate tectonics to be unique to the earth? I would not go so far that complex life is rare, we have no way of knowing what events in the Earths history are required or not for complex life or even intelligence and every planet is sure to have events in it's history that would affect life... It is highly speculative but a while back there was a fossil that indicated that octopus were already displaying complex behaviors way before the demise of the dinosaurs. A big brain is also not necessarily needed for intelligence , corvids and other birds show a high degree of complex behaviors with brains that totally unlike mammalian brains. It could very well be that a planet with fewer or different events might be more conducive to the evolution of complex life and assuming a planet must be just like the Earth is also a mistake, planets more conductive than earth are possible..

No, I some odd "visions" while doing an EEG that made me wonder why they aren't used recreationally...

Significant: sig·nif·i·cant siɡˈnifikənt/ adjective 1. sufficiently great or important to be worthy of attention; noteworthy. "a significant increase in sales" synonyms: notable, noteworthy, worthy of attention, remarkable, important, of importance, of consequence, signal; More 2. having a particular meaning; indicative of something. "in times of stress her dreams seemed to her especially significant"

I seriously doubt that taking the weight of the oxygen away will make a significant difference...

I'd be willing to bet that there is not enough uranium in the Earth's crust to move a significant amount of CO2 to the moon...

Welcome to the club, I've endured them nearly all my life, nearly every night when I was a kid, less often as I grew older, (I don't know what word I was trying to use here, I have a bad toothache and I think I was a bit less than lucid) up and lucid dreaming and you can have some fun!

I wouldn't say it's impossible, highly improbable is a better way to put it...

Then you really have no leg to stand on...

Humans are predators, killing is part of our instinctive behavior, I see nothing wrong with killing animals for food....

I tend to agree that just killing things for fun is somewhat less than sane but unless you have a different solution to the real problems we face then you are part of the problem...

What would you recommend as a solution to the problem?

John, if you don't have a gun and someone breaks into your home what would prevent them from doing you bodily hard?
