Beyond Earth 'Enterprises' ...

Should we humans of Earth ~ Sol 3, consider exploration and expansion beyond our 'solar system', or not ... ???

Enter here the general philosophical dialogue ...

If so, such is the Quest~Destiny, how the to go about such ... ???

Generation "mini-world" ships slowly tugging about a low~sub-light speeds ???

Or same at closer to "light speed" accelerations where the parent vessel serves as base vessel in the new world~system? ... ???

As the the "New World System" is developed and colonized, would this "Colony Development Ship" re-charge to move on to the next world/system of development ??? ...



Let's think a progressive developmental sequence of actions here ...

For now, between a couple of decades to a couple of centuries ...

Lots of variables to play out ...

Let's get off this rock and populate the other ones in our system for now. If we get that done we can learn how to make longer trips.
That's essentially how ancient mariners did it. Sending a canoe full of people to another system won't get us much except by sheer luck.

None at the moment I suspect. However, when the sun runs out of hydrogen, and starts eating helium, its enlarged size may make Titan a viable home for mankind.

To get to other solar systems we are almost certainly going to need a new power source or means of travel. What is useful is that time slows down the closer you get to the speed of light, so while a trip may take decades, or even centuries, from the viewpoint of Earth, the passenger may experience next to no time in relation to those viewers, and thus arrive at about the same age they left (assuming we can approach light speeds)..

The only things preventing moon colonization are a lack of water on it and a lack of will to do it. Mars is slightly different. In that case, it's distance and lack of will.

I think cost is a real barrier to this enterprise. Who is going to fund it?

To do anything serious we need to find a much more economic way to get a significant payload out of the Earth's gravity well

I think that originates here.
