Sorry about that, got knocked off.
A sketch of the luminous part of a galaxy surrounded by a much bigger halo of invisible dark matter. We detect the presence of the dark matter by its gravitational effect on stars and gas within galaxies and on other galaxies. But because it emits little or no light, we cannot see it directly. We do not yet know what the dark matter actually consists of.
I believe Dark Matter, once understood, will be the key to universe travel. As we all know, our current capabilities of space ship propellent will not allow us to properly reach light year goals, or to go to possible inhabitable planets. All energy sources are developed on earth and I think that is a mistake. This idea came to me in a dream. What is one area that we have not looked for alternative energy sources get us where we would like to go? Space. Dark matter is dark energy, and powerful energy that keeps solar systems together. I propose we embark on understanding this capability, develop a multi, human-generational space team that will perpetuate itself in space as it travels to other worlds and possibilities. They would have to rear their replacement platoon to take over as they aged. The eggs would be in hibernation until rearing would occur. This would probably begin around sixty years old. Their life on the ship would be their world. Just like the monarch butterfly that flies from the north to the south. It is not just one butterfly that does it, but multiple generations going down, and coming back. comments? (if anyone steals my idea for a book, movie, t.v., I'll sue you, because it is already in the can.
Are there earthen materials that can withstand the forces of dark matter? It seems any craft that would carry such travelers would have to originate here. OTOH, there may be forces and materials inherent in this planet that allow enhancements to facilitate intergalactic travel, nuclear energy among them.
Meanwhile, who would volunteer for a one way space trip? I can think of a few people I might like to volunteer; two in particular whose body weight is, unfortunately, prohibitive of space travel as we know it, and whose re-entry into the atmosphere may prove a threat to the planet in general.
Your ideas have been explored in dozens, if not hundreds, of science fiction books. You can’t sue people for appropriation of ideas, particularly very general ones that are put out in places like discussion forums. Duh!
