In about 5 to 6 billion years, the Sun will have depleted the hydrogen fuel in its core and will begin to expand. At its largest, its surface (photosphere) will approximately reach the current orbit of the Earth. It will then lose its atmosphere completely; its outer layers forming a planetary nebula and the core a white dwarf. The evolution of the Sun into and through the red-giant phase has been extensively modelled, but it remains unclear whether the Earth will be engulfed by the Sun or will continue in orbit. The uncertainty arises in part because as the Sun burns hydrogen, it loses mass causing the Earth (and all planets) to orbit farther away. There are also significant uncertainties in calculating the orbits of the planets over the next 5 â?? 6½ billion years, so the fate of the Earth is not well understood. At its brightest, the red-giant Sun will be several thousand times more luminous than today but its surface will be at about half the temperature. In its Red Giant phase, the Sun will be so bright that any water on Earth will boil away into space, leaving our planet unable to support life. |

Author Notes | The future of earth... to be a mirrored, lifeless image of the moon? Perhaps not present tense, but maybe it is if that is the course we are on that cannot be altered. |

Author Notes | You don't really have to be a "tree hugger" to realize how foolish we are when it comes to our treatment of the resources available to us. What sense does their destruction make? |

Forests choking for clean air. Imagine a desert where the rainforest is now. That is what we are doing to the planet.

Author Notes | This lost all meaning when it rhymed perfectly. So, I went with a combination of proximate, near and perfect rhymes instead. Try reading it out loud. I think it still flows as well. Or..... |

Author Notes | Too many people put time or age limits on love. Love can hit with the same intensity that it did in youth at any age. You could be missing out on decades of thrills by failing to believe that it can't happen or that it can't happen again. |

Author Notes | Time is mankind's invention. It serves to restrict us and limit our horizons and thinking. Ultimately it lowers our expectations when they should be limitless. |

It isn't a requirement to follow the 5-7-5-7-7 syllable count. Mine is 4-6-4-7-8. Total=29 syllables. I happen to like a pretty picture and a nice display. If you find it objectionable, feel free to pass it by. :)) |
