To me the world seems to have lost it's mind. Last few days have looked at pictures of gitmo bay and almost threw up. The dehumanizing of people was beyond words. History talked of hitler and auschwitz. Decades later what I saw in those photos of gitmo made me think of images of the the very humiliation that the United states once fought against. Turkey is burning because of fighting back the government turned on it's own people like a mad dog. here in america we finally start getting rights for LBGT . Along comes salvation army saying that it should be a death sentence. Killing people over religion seems to be on the rise. in india women are burning for supposed witchcraft and girls killed being victims of rape . The catholic church is says birth control is wrong . Nuns who argue with church are being excommunicated. In last political race it was debated whether women had a right to their on viginas . People are dying world over because of religion and lack of even basic medical and dental care. there is hope for this world right?
ah...it's space, man...wings are useless in space. :D
Not so, Tom, I'm unflappable.
There is no rush to spread. All that is needed for it to happen as I describe is simply for the population to increase needing more resources. So people build more cities and need more stars after local resources are depleted. If those two factors are correct it is only a matter of time to spread across the galaxy.
As to the technologies, I have generally described the technologies needed as being what we can confidently expect to perfect in a couple hundred years. I do not see which might be insoluble problems. What have I missed?
Cities in space? The International Space Station. Every few years they attached rockets to return it to its desired higher orbit. Fusion power is still a wet dream but another century or two should do it. Changing the orbits of comets and asteroids or mining in place? If we can bring rocks back from the moon and samples from comet tails we can do it on a larger scale.
What more is needed? And we need just 6000 years to double the length of time our civilization has existed. And only 200 to double the time since the industrial revolution.
We are the only animal, Peter, capable of destroying the planet.
But a few billion years ago a very successful single celled plant developed a new method of photosynthesis and began releasing poisonous oxygen into the atmosphere. It was the largest extinction in the history of the world.
Amazingly, a handful of species were able to adapt to an oxygen-rich atmosphere, and they became us. It's all about adaptation.
Is dogmatism rattling around in your head? Let's find out.
Check out the reviews for The Big Bang Never Happened by Eric Lerner. Published by Vintage Books in NY.
And the reviews for The Big Bang: A Critical Analysis by Joseph, Lal, Eastman and Ratcliffe. Published by Cosmology Science Publishers at Cambridge.
I read the Lerner book, liked its treatment of plasma, and mentioned it to a scientifically-inclined acquaintance. He replied with "And I have a bridge I will sell you." That's a result of dogmatism.
Another guy replied with "Riddle me this, Thomas: what causes a roiling motion in a super-heated mass?"
And your answer IS --?
Define "riddle me". If it requires gunfire, I decline.
Define "roiling motion". Is it related to Brownian motion?
Define "super-heated mass".
Relate "roiling motion" and "super-heated mass" to cosmology.
RE: "Define 'roiling motion'" - I suggest you consult a dictionary for the word, "motiion," then follow that with a definition of "roiling," then put the two together.
RE: "Is it related to Brownian motion?" - no.
RE: "Define 'super-heated mass'" - rather than define it, I'll simply give you an example, and you can determine your own definition, since you would likely find fault with any I provided: any form of ejecta from an explosion.
RE: "Relate 'roiling motion' and 'super-heated mass' to cosmology'" - glad to, as soon as you answer my question: "what causes a roiling motion in a super-heated mass?"
arch, you didn't define "riddle me".
You say there was an explosion. What set it off?
No explosion. No super-heated mass. No BB.
You didn't fall off a turnip truck and I won't fall for your passive-aggressive game.
