Yup.

I quite agree that colonization via travel across the space between the stars is unrealistic given our present understanding of physics.

I just find it highly amusing that some of us think we have a full and complete understanding of physics, especially since with our present knowledge quantum mechanics and relativity contradict each other. Since we know (believe) that both accurately describe reality, it seems pretty obvious there is some deeper level of reality we haven’t yet understood in which they are not in conflict.

I find it amusing that none of our science even acknowledges that consciousness exists (other than quantum physics, but only obliquely), much less even begins to explain, yet we think we are so smart and have it all figured out.

Pretty colors on an MRI screen showing the part of the brain that lights up when you think of a cat is just pretty colors on an MRI screen.

The reason science is afraid to address consciousness is because it might lead to ideas like... a Creator, for instance.

“I quite agree that colonization via travel across the space between the stars is unrealistic given our present understanding of physics.”

There was nothing unrealistic about human interstellar space travel when a willfully ignorant professor declared it to be unrealistic at a university seminar in 1966, and is far less unrealistic with what we know and can do in 2013. Multi-generation interstellar travel is possible with current technology. Ion propulsion is quite capable as a method of sub-light propulsion. For the inhabitants of the interstellar habitat, the trip would be little different in their lives than staying home in the Solar System.
