I don't think you realize how big a single galaxy can be. an advanced civilization could stay in one galaxy for millenia and not see it all. This is a wonderful find, will watch developments with great interest.
I don't think you realize how fast humans are capable of multiplying
Say it takes 10000 years to build a world the size of earth and it requires 100 million colonists to do so. A planet the size of earth is capable of producing 100 million colonist every 1000 years.
So here we go: After 20000 years there are 10 earth sized planets. After 30000 years there are 100 earth sized planets. After 40000 years there are 1000 earth sized planets. After 50000 years 10000. After 60000 years 100000. After 70000 years 1000000. After 80000 years 10000000. After 90000 years 100000000. After 100000 years 1000000000.
I think we can now consider the galaxy colonized (depending on the amount of habitable worlds). After 100000 years already. Using in my opinion conservative values.
Of course this is a very simple model and if you take in account that the new worlds will also be able to colonize other worlds in between the 10000 year interval, the growth rate is even higher. Also, I think my estimates are way in favor of slow growth. The population of earth grew from 1 billion in 1800 to 7 billion now. That is a growth of about 350% each 100 years. This means that earth sized planets are capable of producing way more colonist, but it also means that new worlds will be populated way faster.
So I disagree, I think I do realize how large our galaxy is, but I think you underestimate the expansion rate of humans.edit on 20-9-2012 by -PLB- because: (no reason given)edit on 20-9-2012 by -PLB- because: (no reason given)

Heya all
this is an interesting theory however i do feel that until we have asertained (excuse the spelling lol) a way to control or manipulate the dark matter that is apparently out there we just wont be able to produce the bang needed but if we can manage that then there would be no need for fuel as the entire mass of space itself is supposed to be full of it.not sure about the bending time space bit though.

Plotting a course back over long distances would have to take into consideration the speed the solar system is passing through the Milky way and the speed and direction that the milky way is moving in the universe. That would make computations almost impossible because we have no reference points to "zero" in on. Everything is moving.

Maybe some men made it to the moon, but it wasn't anyone from my town. It wasn't anyone I have met and befriended either. What are the odds of you ever getting a ride into space, the common man. Humanity as a whole? Maybe a few guys that are chosen by tptb because they are good at PR. They just make us pay for their research, we don't get to participate at all.edit on 24-9-2012 by rickymouse because: (no reason given)

The trip to the moon cost everyone to work harder to pay for it for many years. It's like having all taxpayers pay for a huge football dome, the game could still be played without the dome. If NASA took all their brilliant minds and focused on monitoring and fixing the problems we are creating with the world even for two years, we would have a much better world.

Their goal is space and associated technologies. Not saving the world.

True, but cutting edge space technologies can certainly shift paradigms and save the world

To solidify my point, the conversation here is analogous to a letter I recently read...
NASA scientist responds to nun's question; Why explore space?
Enjoy.
