From what I read from Hawking it is dark matter not dark energy, I might be wrong though it has been over a year. The non existent part is something that has been revised as of resent, physicists now say they exist but in a different state of matter I believe it turns into dark matter. Apparently dark matter has massive amounts of energry and can even be used to create a black hole but we have only created microscopic amounts. I have herd that for dark matter to be used as fuel we would need an earth's mass amount ... so that's the challenge in that. Also like you said very little is actually known about dark matter though that is in the process of changing.
Yea I think the big bang theory will change a lot as time goes on, and that is because there is a lot of current questions that still haven't been answered in the theory. One thing we know by using the light spectrum on stars is that the universe is expanding and that has to lead one to definitely believe their was some giant explosion at a some singularity at some point.
I love that too, it could very well be the only thing of man-kind that will last .... it is our only real footprint amongst the cosmos and hopefully one day another species will see it! There is also a golden record ... I forgot which craft its on but it has some of earths best music on it.

It is unknown whether it is valid or not, some people argue that it will not occur because an expanding universe can't reach a temperature that low for this to be possible, but don't take my word for it and read
this Wikipedia article, I am not sure what Hawking s view on the whole thing is, but I think he has one in some of his journals or something, I will have to check that up.
What you say about dark matter might be true, I haven't checked into that very much but I will later!
Oh Johnny B. Goode, how you will be loved by another species, if they have the curiosity to be interested in it, and enough "luck" to be able to open it and play all of these things.
Yeah, the expansion is proven, stating that it was at a singularity at one point, however there are many mysteries left to reveal before we get remotely close to a complete model of space 14 billion years ago.
Here's the list, rewritten by me as it was originally done by Carl Sagan in A pale blue dot:
"Accordingly, as each Voyager left Earth for the planets and the stars, it carried with it a golden phonograph record encased in a golden, mirrored jacket containing, among other things: greetings in 59 human languages and one whale language; a 12-minute sound essay including a kiss, a baby's cry, and an EEG record of the meditations of a young woman in love; 116 encoded pictures, on our science, our civilization, and ourselves; and 90 minutes of the Earth's greatest hits-- Eastern and Western, classical and folk, including a Navajo night chant, a Japanese shakuhachi piece, a Pygmy girl's initiation song, a Peruvian wedding song, a 3,000-year old composition for the ch'in called "Flowing Streams," Bach, Beethoven, Mozart, Stravinsky, Louis Armstrong, Blind Willie Johnson, and Chuck Berry's "Johnny B. Goode. Space is nearly empty. There is virtually no chance that one of the Voyagers will ever enter another solar system-- and this is true even if every star in the sky is accompanied by planets. The instructions on the record jackets, written in what we believe to be readily comprehensible scientific hieroglyphics, can be read, and the contents of the records understood, only if alien beings, somewhere in the remote future, find Voyager in the depths of interstellar space. Since both Voyagers will circle the center of the Milky Way Galaxy essentially forever, there is plenty of time for the records to be found-- if there's anyone out there to do the finding.
We cannot know how much of the records they would understand. Surely the greetings will be incomprehensible, but their intent may not be. (We thought it would be impolite not to say hello.) The hypothetical aliens are bound to be very different from us--independently evolved on another world.
Are we really sure they could understand anything at all of our message? Every time I feel these concerns stirring, thought, I reassure myself: Whatever the incomprehensibilities, of the Voyager record, any alien ship that finds it will have another standard by which to judge us. Each Voyager is itself a message.
In their exploratory intent, in the lofty ambition of their objectives, in their utter lack of intent to do arm, and in the brilliance of their design and performance, these robots speak eloquently for us.
But being much more advanced scientists and engineers than we-- otherwise they would never be able to find and retrieve the small, silent spacecraft in interstellar space--perhaps the aliens would have no difficulty understanding what is encoded on these golden records. Perhaps they would recognize the tentativeness of our society, the mismatch between our technology and our wisdom. Have we destroyed ourselves since launching Voyager, they might wonder, or have we gone on to greater things?
Or perhaps the records will never be intercepted. Perhaps no one in five billion years will ever come upon them. Five billion years is a long time. In five billion years, all humans will have become extinct or evolved into other beings, none of our artifacts will have survived on Earth, the continents will have become unrecognizably altered or destroyed, and the evolution of the Sun will have burned the Earth to a crisp or reduced it to a whirl of atoms.
Far from home, untouched by these remote events, the Voyagers, bearing the memories of a world that is no more, will fly on."
