    If you thought global warming was alarming...

    ...Spiral galaxies, like the Milky Way, only produce new generations of stars as long as they have dense molecular clouds of interstellar hydrogen in their spiral arms. Elliptical galaxies are already largely devoid of this gas, and so form no new stars. The supply of star-forming material is finite; once stars have converted the available supply of hydrogen into heavier elements, new star formation will come to an end.

    The current era of star formation is expected to continue for up to one hundred billion years, and then the "stellar age" will wind down after about ten trillion to one hundred trillion years, as the smallest, longest-lived stars in our astrosphere, tiny red dwarfs, begin to fade. At the end of the stellar age, galaxies will be composed of compact objects: brown dwarfs, white dwarfs that are cooling or cold ("black dwarfs"), neutron stars, and black holes. Eventually, as a result of gravitational relaxation, all stars will either fall into central supermassive black holes or be flung into intergalactic space as a result of collisions.

    Edit:

    From is above is from Wikipedia. I'm not an astrophysicist...

    Charles E, we have never met, but am looking forward to that day. You are one of the very interesting people on this website. I enjoy reading your very informative information on benchrest shooting, technical and thinking out of the box. But your annilitical (sp) views are astounding. Keep up the good info. I'm not educated by any means, but you sure know how to grap attention! waynej

    Yeah! Sure! How are you going to verify that?

    Jerry,
    Maybe Charles just moved to Colorado or Washington and is exercising the new laws therein.





    Just kidding Charles.

    Have you heard the one about our observable universe being a 3 dimensional (+ time) holographic projection on a 5 dimensional brane? ("brane" as in membrane, not brain)

    Somehow I suspect that we haven't gotten to the bottom of this yet and very possibly aren't capable of it. (anything within a system cannot model the entire system)

    That 10-100 trillion years is indeed something to be concerned with. But, more imminent is the demise of our sun in a mere 4,500,000,000 years, give or take a few million or so. Now, THAT'S going to be global warming!

    Ah, but before the demise of the sun, we'll have the technology to escape our solar system & go pollute somewhere else. The end of the stellar age, though...

    Charles how can we know all this and still don't know if a hard front bag causes vertical. A lot of theories about the past and the future that are far fetched. I find it way easier to believe in God. I wish everyone on Benchrest Central a very good year, even Mike. Mine looks good. Stephen
