For the life of me I do not see how atoms and larger particles can suddenly decide to fuse together and create a planet that has enough energy to melt it all together. Sounds more like Mickey Mouse than reality! I am by no means alone in an expanding earth, in fact it was for many years the only explanation. Plate tectonics offered another explanation to the way continental drift occurs. But by no means disproved the growing earth problem.
Yes, indeeed and we are several orders of magnitude to cold for nuclear fusion- even the sun's core is (as I said) too cold to do that very quickly. Also, the core is generally agreed to be mainly iron. This would get in the way of the hydrogen reducing the rate of fusion still further.
Lets say 3 million atmospheres at the core. (A figure quoted by others) This immense pressure would undoubtedly suffice to push atoms close enough to excite them and fuse them together! No need for the immense heat you are asking for evidence of!
Hydrogen appears to be married off with oxygen on earth. Whereas in space hydrogen appears to be happy all by itself!
Andrew, OK I forgot the squared term. Oops!The pressure at the earth's core is roughly 3000 times less than at the centre of the sun so the rate of fusion is roughly ten million times less.You seem to have shot yourself in the foot.Oh, I almost forgot. Hydrogen is common. Another thing it is is less dense than molten rock.It would float up out of the earths core. Since it's not there, it can't fuse.Free hydrogen in the atmosphere gets lost to space- it's to do with escape velocity and the Boltzmann distribution.
I doubt also that hydrogen makes it to space when it is liberated but combines with free oxygen molecules to reform into water
QuoteHydrogen appears to be married off with oxygen on earth. Whereas in space hydrogen appears to be happy all by itself!Could that just be because there is a lot of Oxygen around the planet so the Hydrogen atoms which find themselves here will combine with them? Did you see some particular significance in what you wrote?
Andrew please stop posting nonsense."You cannot destroy water molecules. You can however change them into something else!"
Water is the only substence that resists all difrent states.
"is thought to be a weak force because it is not understood and it is well known and publicised that gravity is not understood. "Bollocks again. Gravity is thought to be a weak force becaus it has been measured and found to be weak.If I pick up a book I can do so in spite of the fact that I am working against the gravity of an entire planet.That's a weak force. How well understood it is doesn't matter- if we come up with a better theory to explain it we won't suddenly weigh more.Again, I wonder why you write such tosh.
Even short term space flight poses very serious health complications for astronauts.
