The Universe Is Fading Away.

The energy output from the universe is on a downward spiral. Nearly halved in the last 2 Billion years. Star creation reached it's peak long ago and the universe is on a downward path. Nothing lasts forever. Still eons of time to go though so don't cancel your plans. :-)

    Yup. Lighter elements become heavier elements (in the process of star formation and star death), and eventually stars no longer are created.

    So the universe will eventually be completely dark. Then the black holes will eventually dissipate, and then the universe will be a dark cold expanse of nothing...with wisps of protons.

    And nothing will exist except ghosts, and Twinkies.

    Merry Christmas.

    What if they're not stars? What if they are holes poked in the top of a container so we can breath?

      I'm getting a lot of Christmas Greetings recently, are you Santa Claude?

      How did you know about the Twinkies?

          Unfortunately we will not be around to verify this. Isn't the universe expected to last at least 2-3 billion years yet?

            Much longer than that. Our own sun is about halfway through its life expectancy of around nine billion years, and new stars are still being formed. So the universe has quite some time left yet.

              In 4-5 billion years, out Sun will expand and engulf the Earth anyway. but there will be new star formation for trillions of years to come. Most of the universe is still hydrogen. And hydrogen is what new stars are formed out of.

              It's only when most of the hydrogen and helium are gone, and the heavier elements are all that's left, that new stars won't form.

              Interesting to me; Some stars are so massive, that they continue their nuclear fission, creating heavier and heavier elements...until it gets to iron. Iron stops the process. There are dead stars that are literally perfectly spherical balls of 100% iron.

              This wasn't directed at you Frank, but you triggered the thought.

              Nope. The universe is expanding at an ever increasing rate. It's not that galaxies are repelling each other, but that the actual space between them is expanding at an accelerating rate. Eventually, we won't even be able to see another galaxy, they will be retreating too fast.

              And if life exists on any planet in our galaxy, they won't have any knowledge that there were any other galaxies. Weird.

              This is all completely counter intuitive, I know.

                "In 4-5 billion years, out Sun will expand and engulf the Earth anyway"

                In 1.75 billion years the sun will have swelled and be burning hotter and boil away the oceans of the Earth, extinguishing all life and putting us outside the habitable zone.

                You never know. You might get some activity on Mars for a while. It's not likely but the extra heat might bring out frozen trapped gases and water underground and bolster the atmosphere for a bit. life not that likely as no magnetic field shielding. Unless they are scorpion type creatures.

    I don't plan on being in the 3rd dimension too much longer and figure that the other dimensions will still be pretty active after this one stops............if it does. Who knows what other catalysts exist out there, somewhere. This is only one universe of billions.

      No contest, nothing (no attractant) to make it all fall back so it eventually burns all it's material and fizzles out.

    I bet in 50 years time we were wrong, and then 100 years time the theory proving that theory is also wrong. But I must admit, claudes poetic description was quite good
