    • Yo i thought of a way how humankind could survive the cold-death of the universe. I know its just a theory but please follow me on this. So we know if humans survive long enough we can become an atleast type 2 society. If we get this far we could decompose dead stars and gas planets drive them both together and create a star artificially. I must admit i know very little about it but it could be possible. I mean we could create a dyson sphere or smthng around it and transport it via an hyperspace engine to a gas planet decompose both and see the star form it self. With decompose i mean blowing them up but with much less boom ya know? Maybe a laser of sorts or other things. Its crazy i know but it sounds great in theory. Waht do you think? Let me know ^^

  • Its the false vaccum thing that keeps me up at night. Strangelets are a spooky concept, but probably not a thing, or it would have wrecked us by now. But the vaccum energy of the universe is fundamental, and with a bit of math you can plot out ways of breaking it, as implausibly difficult as it would be. And thats not "weird shit eats a star", thats "nothingness eats a universe"
