I don't think there is a connection between blue eyes and blue skin. Blue eyes is more from a lack of pigment than actual blue pigment at least in humans.

As much as I'd like to see a great many of the people who claim to represent the republican party burst into flames and disappear from the face of the earth I think the reality is that a great many people are really between each party in their real convictions and they waffle back and forth in support of each party as the parties tend toward the party extremes. Most people or at least large portion of them do not swallow all the rhetoric of either party without question, this is a good thing because blindly following anyone leads inevitably to the koolaid and disaster.

I was under the impression that opinions didn't hold much water on this forum. I have many opinions they are wide and varied but I do not use them to make my point or to try and make the points of others look unimportant or ludicrous. Using the idea that the opinion of the average American is more important than the law to ridicule evidence of breaking that law is not what I thought discussion was about on this forum.

Having an opinion doesn't make any one correct, opinions often have to be ignored to cut through to reality.

I am pretty sure that in astronomy ice means simple compounds of Hydrogen and oxygen or carbon or nitrogen or sulfur when they freeze. Granite is not considered an ice.

Bullshit I do not see the connection of allowing those who have religion to practice it in the military to the top brass using it to further their agenda. Further more the idea of there are no atheists in fox holes is nothing but proselytizing. Only those with a religious agenda say this. I know atheists who occupied "foxholes" danger does not make an atheist cry out for God but it might make him curse those who use the idea of god as an excuse to put him in that foxhole.

So the the surface of the ocean on Uranus is covered by ice? Even at the pressures involved the temps would seem to preclude ices. The temp of -355 is the top of the atmosphere, the top of earths atmosphere is less the the freezing point of water but you don't consider the earth to be an ice planet. or that ice is a significant part of it it's make up. be that as it may. I my main interest here is the possibility of a large planet with gravity close to earths IE a 12,000 mile planet with a surface gravity of less than 1.25X of Earths, for a story I am writing. I'd like for it to be plausible at least.

I didn't wish the wrath of god on those assholes, i don't believe there is a wrath of god, only the wrath of those who believe in iron age fairy tails. I resent very much my government trying to use those fairy tails to rally the population or in any way connect our government or it's actions to iron age fairy tails.

Scone, no one has ever died from eating or smoking too much pot, non one has ever found a level toxic enough to kill, you eat enough and it is a less than desirable experience but not death. Polyploid I think thats the word, they manipulated the seeds with teratogenic chemicals to change their genetic makeup it grew under ideal conditions as inside a greenhouse but it was 20' tall and 4" thick. If it had been outside the wind would probably have destroyed it was weak despite is size.

Back to the OT. I've seen ployploid Cannabis plants that were 4" thick at the base and almost 20 feet tall, almost trees !

Then there is He3 fusion, but we'd have to go to the moon for the fuel for that.....

Ceramics would be my guess, several metals can also withstand those temps. Carbon can if it's not incontact with oxygen.

Try again dude, there is not enough energy in a solar flare (as it contacts the earth) to melt any ice in Antarctica or any where else. The ozone hole has nothing to do with our magnetic field or the solar winds hitting the earth.

The Earths magnetic field will not lift a sewing needle, it will not lift a 150 pound magnet or a 150 ton magnet no matter how strongly magnetized it is. Your idea of magnetic fields is not connected with reality. The Earth's magnetic field is very weak, compared to it's gravity. I see no way possible to use the Earths magnetic field to levitate huge stones.

Studying the biology of the Earth might be affected by diminishing returns but if we found life on another planet then biology would be wide open again. I think we will always be finding out new subsets of knowledge. If not a new way to think of the idea of "universe" then unknown subsets of the universe would open up whole new fields of knowledge and science. Just because we think something is impossible to know now doesn't mean it will always be unknowable.

I really have to say here that the Earths magnetic field is too weak to levitate a sewing needle much less a chuck of coral stone weighing several tons. If indeed this guy levitated these huge stones it was not by using the Earths magnetic field........

You mean every man in the USA doesn't have "Shorty's Esso Service Station Chattanooga Tennessee" tattooed on his penis?

So a huge planet with a small iron core composed of mostly granite like materials as proposed by Asimov would still be as dense as the earth? He seemed to think it would maybe 12,000 miles in diameter with a surface gravity close to earth normal but with a much denser atmosphere due to the less steep gravity gradient. Merged post follows: Consecutive posts mergedI thought the general consensus was that Uranus and Neptune were worlds of extremely hot water oceans thousands of miles deep over Earth sized rocky cores. Far to hot to contain ice of any kind.

Even in space solar power is limited, solar power is not enough for a space craft that contains humans. Even our unmanned probes are severely limited by the limits of solar power. That is why thermal nuclear power is added to most complex space craft. IE plutonium heat generated power. To generate a positive electric charge to repel the solar wind would take far more than the available solar power but it is doable with nuclear power. Fortunately in space you do not need to shield the entire reactor. The crew can live in the shadow of a small shield when the reactor is powered up or tow an unshielded reactor far behind the space craft on a tether.

The worst effects of pot use are indeed jail or being robbed and beat up by a dishonest dealer and ending up in the hospital. None of these things is due to pot but to the effects of the laws making it illegal!

It all sounds good but how many square meters of solar panels would it take to generate enough hydrogen to cook on much less heat your house and have some left over to sell to others? I used about 130 gallons of propane to cook and heat water in my home in six months. does anyone know how much energy that represents as hydrogen and the electricity to make it? I'm betting that much energy would take a huge solar panel to generate the required electricity to make hydrogen and that doesn't include heating my home.

Life will find a way to quote an old movie but realistically in Uranus there should be much more heat and chemical energy than there is in the Earth and such chemical and heat energy similar to the "black or white" smokers under the ocean of the earth could indeed supply large amounts of energy. Life is not about consuming all the resources available but more about recycling them. One creatures waste product is another creatures food. Heat and chemical energy could power this recycling process in Uranus.

So Captain, you are going to panic and ignore all the hydrogen in Uranus? Spank me now, I couldn't help my self..........

so a planet made of exactly the same elements and Mars in the same proportions would be dense as the earth if it was much bigger than mars?

Venus is thought to lack plate tectonics, lack of water as a lubricant between plates and possibly lack of a large moon have been suggested as possible reasons for this lack. Is it possible to have a large diameter planet with a similar density to Mars? If so would it be likely to have plate tectonics?
