I’m serious about promoting this galactic shock-wave story. Because for one thing it will happen one day so lets get started now. And secondly it appears that there are people who need a doomsday scenario in their life to combat. Like someone has cut themselves slicing lemons. Its a little cut but they say it stings. You stomp on their toe, you say “Does it still hurt?” And if they claim it does really they are lying since their toe hurts more.
At least this galactic shockwave business isn’t proved wrong. Unlike the CO2-Emissions racket. So I see it as prudent and pragmatic to promote this other potential calamity. Since the CO2-Emissions calamity cannot happen.
I see the inevitability of culling via galactic shockwave, as an extension of the way planets grow. Ex-Moons like Mars will eventually grow to be like Earth. Earth-style planets will grow to be gas giants. A gas giant like Jupiter is destined to become a star. From what I can glean from how Neal Adams thinks about it, this works in smoothly with the expanding universe, accelerating in its expansion. I’m not really buying the smoothness of it, if this is indeed Neals view of the situation. Its doubtful to me that the universe is even accelerating in its expansion. Nothing in nature is ever quite that smooth.
If this growth all continued there would be a great deal of matter and not much space. So what we have with these shockwaves here is some pre-emptive pruning. The shockwave comes out and explodes a few planets and stars that are a little bit on the unstable side. Now we are getting an answer to Fermi’s paradox. Intelligent life will begin at the centre of small galaxies. But these guys will realise they cannot survive there. The movement has to be outward. Outward and to the fringes. Its in everyones interest to terraform to the outside of themselves, if they can do so in a set-and-forget way.
Hence we ought to expect that whilst evolution is part of the picture, we might be getting a little intermittant help from the outside as well. Not a great deal of help. The distances involved are way too large for that. But there can be little question that we would do the same if we were able. We would terraform the moons of Jupiter and Saturn with appropriate life for those conditions, if we could do so cheaply and in a set-and-forget manner. And if Jupiter or Saturn didn’t themselves get culled, they would eventually branch out and become their own solar systems. With their moons becoming planets.
To have everything expanding smoothly with the allegedly accelerating universe covering for all this growth, doesn’t sound like nature to me. Nature is a much more demonic and messy sort of thing.
