I learned that the earth was being warmed by the burning of fuels that gave off carbon dioxide. They are called fossil fuels. They all come from organic matter buried in the ground millions of years ago. They were used only rarely until the invention of engines that could produce useful motion such as turning a shaft in a machine. The world was turned upside down by the first of these the steam engine.

Such machines proved so useful that thousands and then millions of such machines were built and they powered factories, trains, automobiles and much more. There use was assisted by so-called “oil companies” that processed the raw material that came from the ground into fuels such as gasoline, diesel, keroscene and others.

The oil companies did research to see if burning these fuels could be harmful and they found that it would, but kept the knowledge to themselves. They were also warned by the famous physicist Edward Teller when the oil companies celebrated 100 years of their business. Excepts from his talk are reproduced below.

How Many Are There?

Earths, That Is

How many earths ARE there. It is impossible to tell. There may be billions. There may be a few. There may be one.

It all depends on a host of factors. (SETI, The search for extraterristral intelligence, listening for radio signals in our galaxy for the past 40 years has heard nothing.) If there is life like ours, then perhaps we would hear a radio signal with clear information in it.

Or, we can look through telescopes, but that dosen’t reveal a whole lot. It all depends on how much needs to be just right. It is possible there is only one, or that there are billions. My own intuition says there are a ”few.” But perhaps the number doesn’t matter. What matters is what the earth does for us, and that is how global warming brings up the greatest question there is.

As best as we know life originated on the earth and evolved over millions of years to create homo sapiens. That is us.

So “us” is asking the question what is LIFE (caps intentional). This is the place where something throws me, because I have to answer the question about Life, and hardly anyone talks about it even the physicists who talk about theories of everything. As far as I know they talk about the four laws of physics and leave it at that. Then I start asking what is it that is so special about being alive and that blows my mind.
