Crows are pretty damn smart

You probably missed my post, Peter, (it was right before yours), but he changed is s/n to boost the google rank for a "run for cancer" charity event.

I fact I didn't.
I thought 'RSU co-operation run for cancer' that you mentioned had to do with the name rsucoop.
I haven't got a clue what gymsum has to mean.
And as gymsum was the second account, why did he take gymsum, his second account.
So why did he take a second account?
Or did I confuse myself and was it gymsum that had to do with a charity event?
Numsgil:
He was originally rsucoop. The top google hit for rsucoop was his user profile here, so he made a second screen name (gymsum) to try and lower the ranking of his rsucoop's profile on google, and thus raise the google rank of the charity run. That's why he changed accounts, he wanted to boost the page ranking for the charity run, so he had to ditch his rsucoop account.

--- Quote from: gymsum ---WHen you consider the first principle of thermodynamics (one of the major guding forces in the universe), all heat is, is movement of particles; the mroe movement/higher-frequency the more heat. So if we start with electricity (lightning to be exact), we see multiple results from one event; the lighting super heats the air instaneously, breaking donw the composition of the air to produce nitrogen, intense heat and light.

Do you mean the ionisation of air by lightning.
--- Quote ---We also know that sound/light and heat act on the same principles of the inverse square law, and so the sound wave (if at high decibles) has the potential to cause air to heat or cool based on the work done by the sound wave impacting particles.

I can boil or freeze water by setting the radio high???
Eh.., think. Sound is more like a variation of pressure, no real energy.
--- Quote ---We know that the universe in a constant exspansion, so as the stars burn up and use the remaining gases, the energy content of the universe will continue to expand outward and as far as density is concerned, the energy can be said to be "spread thin". True some of the matter will collect from gravity, but as the matter changes states, percentages of the exsisting fuel/mass changes from entropy.

1. No, we don't know the universe is constantly expanding.
2. Stars don't burn.

Hmm...
A simple chemical formula.
CH4 + 2O2 -> CO2 + 2H2O and energy
Burning of methane, forms energy, no mass is gone.
Sun.
Simple question, in my small post before yours. I stated that the sun loses 4 tons every second. Can you explain where that mass have left, and how, and why, and anything particulair about it, I'd like to know how much your rabling or that you really have a idea what you're talking about.

If you lower pressure like in a vacum, you can boil water which releases its energy and thus freezes. If you increase the pressure the water's temp will drop and then increase. So even with Boil's principles of pressure, sound should produce a result at very low frequencies.
Also, Times magazine did an article on the exspansion of the Universe, it hasn't slowed and most scientists assume so, and like a flat Earth, what we presume is only a theory. Sorry for the misspeak.
The loss of the mass of the sun has to do with energy consumption during light emission. Recall E=mc^2; well say 4 million metric tons is lost a second. We haev calculated the amount of energy produced by the sun in ergs, about 4 x 10^33 ergs/sec. We know the mass loss is equal to 4 x 10^33 ergs/sec, and we have our original equation so divide the energy out by the speed of light squared, or (3 x 10^10 cm/sec)^2 and you now have an equation to calculate the loss of mass due to energy-light crap. (sorry for lack of jargon). Taken from the suns total mass and radious, at this rate evry 160 billion years the sun will lose 1% of its current mass. So to produce 4000000000000000000000000000000000ergs/sec it must consume/alter the state of 4 million metric tons of (fuel I guess) per second, or 1 onehundred-sixty billionth of its entire mass a year. I think thats correct, if my notes are still acurate.

It's Boyle's law. Not Boil's law. Although I think it would be funny if his name was boil. Would make remembering it that much easier.

That the universe is expanding has been known since at least Hubble (the scientist, not the telescope). If you had two objects in space, and neither object is accelerated, after billions of years they would end up further apart, because the actual space between them is expanding. See wiki. This makes sense when you consider the fact that the universe literally exploded out from a single point. The more interesting bit is that this expansion is accelerating. This is where the whole idea of dark/vacuum energy comes from.

Didn't check out your math (math is boring). But this part you glossed over is the interesting bit, IMO. What fuel is used (what was that mass before it was converted to radiant energy), what reaction takes place, etc.
