  •  Hey, the Sun's not going to last forever you know! (19+ / 0-)

    Nor is the moon! So I hope you have a plan -B- C!

    •  Dang, BentLiberal, this is a tough crowd. Just (16+ / 0-)

      when I deal with one snark-troll I've picked up two more, you and elfling are now busting my chops.

      Are you old enough to remember the original Star Trek, when Bones McCoy would say, "Damn it Jim, I'm a doctor, not an engineer!"  

      I didn't expect this to be like a PhD exam, or a Spanish Inquisiton.

    •  Redirect white dwarfs towards each other... (5+ / 0-)

      If we can survive the next 100 million years I expect we should have figured out a lot of new things.

      So, first utilize energy from red dwarfs which should shine upwards of 1 trillion years. Use some of that energy to collapse diffuse hot hydrogen to form more red dwarfs. That should be good for another couple trillion years.  We will end up with lots of helium white(black?) dwarfs.

      Take the helium white dwarfs and redirect their orbits toward each other.  Not sure what happens when a pair of small cool helium white dwarfs would do when they collide.  Merge into a larger helium white dwarf?  Get enough together to exceed the Chandrasekhar limit and ignite a supernova.  After several trillion years we should know how to collect most of the energy output of a super nova.  So, repeating that over and over should be good for another several trillion years.

      After that the only option will be to direct the debris from our supernovas towards the most efficient matter to energy conversion in the Universe. Black holes.

      We will want to be careful here to use the largest black holes only and prevent energy from going to smaller balck holes because once we run out of matter to shove down black holes.  The only possible energy source will be hawking radiation from evaporating black holes.

      Eventually, we will reach heat death of the universe, where it will be a uniform very cold photon soup.  With no energy gradients there will be no way to harness energy to do work.  The only hope then is that after many 10s of trillions of years we will know enough about physics to set off big bang 2 and move into a new Universe.

        "StarBright" Super telescopes that concentrate the light from distant  stars.

        Or should we call it "TeleStar."

        I've got to get back into business. I love making up new companies.

        Did you I was actually an Inc 500 CEO back in the 80s? I had the 372 fastest growing privately held firm in the United States for a five year period. And, was a 1 percenter.

        Until my ex-wife and I divorced, had a 10 year probate court battle, I suffered from clinical depression and lost everything.

        But, I'm getting ready for the comeback trail.

        of the human race long before we have the opportunity to explore these whimsical energy sources.

        To put the torture behind us is, inevitably, to put it in front of us.

        •  Yes... (0+ / 0-)

          The next couple hundred years or so will probably decide whether humanity goes to the stars or ends up going extinct on this planet.  I am not saying that we would actually send people out in a couple hundred years, if all goes well, just that it will be apparent what the end result will be in that time.

    •  Proxima Centauri will be around long after (0+ / 0-)

      Though still not forever. But long enough, I'm sure.

      By the way, could they possibly use these on interstellar spacecraft to provide some electricity from the accumulated starlight?

      And God said, "Let there be light"; and with a Big Bang, there was light. And God said "Ow! Ow My eyes!" and in a flash God separated light from darkness. "Whew! Now that's better. Now where was I. Oh yea . . ."
