[quote]@Angillion Roughly speaking, what percentage of your nearly 9,000 posts are as long as your posts here?[/quote]

I`d say that most are longer. I`d make a vague guess of about half a million words, using the typing speed standard of an average of 5 characters per word.

[quote]How many books do you think you have written?[/quote]

None. Books aren`t just a lot of words. It`s a different skillset. I`ve written a handful of short stories and I`m crap at it. Writing is easy. Writing a story isn`t.

[quote]@Theyoyoguy We can not detect the chemical composition of exoplanets mainly because the method for detecting them measures the dimming of their host star when they pass between it and our detectors. There is no visible light coming off of the planet for us to measure.[/quote]

Visible light from one was detected recently because it`s big enough and close enough to its star to reflect enough light to be detectable (barely) with current technology.

It`s also apparently possible to use changes in what we detect from the star not only to deduce the existence of a planet but also to make an indirect spectral analysis of the planet by how it affects the spectral analysis of the star. I didn`t know that - I thought you could only get the size from that.

Looks like at least one planet has had its spectra measured.

Good point, as long as you consider a planet`s atmosphere to be on the planet. Which it is in a sense.

It only tells us some things about the atmospheres of some exoplanets (yet - more advanced equipment would make more possible), but you`re right - it is more than nothing.

[quote]What rubbish, `we don`t know what`s on any of them`.
Of course we bloody do.[/quote]

Not really. We know something about what`s on the other planets in our solar system, but the text you quote was explicitly referring to planets in other stellar systems. We have only detected anything from a handful of those planets (all the others were detected indirectly as a result of their effect on other things).

We can make some educated projections about exoplanets based on the roughly accurate calculations of their size and mass and the amount of energy that reaches them from their star, but that`s not knowing what`s on them. At best, we can say things such as "this planet almost certainly has a solid surface with a temperature probably averaging about 40C". So I suppose it could be said that we can be almost certain that there are rocks on some of the exoplanets.

Oh, really? Then provide a reference to even a single report (not a theory or an imagining - a confirmed report) of what`s actually been found on an Exoplanet (i.e., one that lies outside of our Solar System).

The graphic isn`t inaccurate in the respect you stated. At this stage we really don`t know anything much about planets (or possible life) outside our own insignificant little parochial bubble.

I have very little doubt in my mind that we are not alone, but you never know.. We very well could be the most intelligent life out there. I sure hope not, though.

And collectively, those are only a grain of sand in the grand scheme of things.

It`s pretty humorous that humans are arrogant enough to believe we`re the most intelligent beings in the universe. Downright hilarious that some think we`re the only life, period.
