I've toyed with this subject for several years, but, as a non-specialist with very little University Physics behind him, I'm severely limited in what I've been able to do. Antimatter-catalyzed fusion has gotten a bit of interest, and even some government research grants over the years...

You already know that a CO2 laser tube contains other gases, most importantly helium. The reason for this is, electrons are very light-weight, low mass particles, but the CO2 molecule is very heavy. When the low-mass electrons strike the high-mass CO2, the electrons don't dump very much of their...

"Relatedness" is in terms of best human judgement, not any purely objective measure. That's why a board has to review how the tree is arranged; the phylogenetic tree is a judgement call.

I was answering your question, though I don't understand the point you were trying to reach.

For a few decades, many scientists expected that the carrier of genetic information would be found to be proteins. After all, pretty much everything else in all organisms revolves around proteins. Yet, we have never found any organism whose genetic information is carried that way. Some viruses...

I don't understand what you are claiming. To the best of my knowledge, T. aquaticus is incapable of infecting us.

Oh, sure, for some definition of the word, evolution is occurring and can be observed.

Why would I think that adenine, guanine, cytosine and thymine would behave differently in one organism as in another? They *are* microscopically alike, because they are chemically alike. Evolution has nothing to do with it.

Even by your standards, that could only vaguely be true. You know that the phylogenetic tree is subject to revision at any time, as it has been several times even in the last few years. You know that new discoveries frequently change the depiction of evolution at all but the most abstract...

I suppose we could use Taq Pol on canid DNA because DNA is DNA, whether in a bacterium or in a dog. Chemical compounds work similarly in similar environments. This is just basic chemistry.

I greatly enjoyed my Biology class last semester. I took General (University) Biology and Honors Biology Lab. I'm glad that we didn't waste our time studying evolution or even a phylogenetic system. We had to rush just to get through all the cellular components that we covered. I got to extract...

Thanks for the confirmation about Sun's reliance on quantum tunneling. What I really would like to know is, how would one make a practical fusion generator? I know that the U.S., former Soviet Union and several countries have spent billions of dollars and half a century trying to answer that...

Oh, I did not know that quantum tunneling is not commonly accepted as the reason solar fusion works as well as it does. I got my information from this video: In the comments, the author says: "People have been asking for the math. So here it is. The Sun's core temp is ~13.6 MK. For...

I've heard that Sun is not hot enough to sustain thermonuclear fusion at the level we observe. Instead, the solar output relies on quantum tunneling of protons through their natural repulsive barrier. Might this same effect be useful in obtaining controlled thermonuclear fusion? It seems to me...
