Re: [PLUG] "Nearby"


I wonder what the relative motion of this newly identified system and our solar system is. Are the systems moving towards or away from each other, or will they maintain the same relative distance over the next several hundred years?

Rich,

Travel time (https://en.wikipedia.org/wiki/Interstellar_travel#Travel_time)

An interstellar ship would face manifold hazards found in interplanetary travel, including vacuum, radiation, weightlessness, and micrometeoroids. Even the minimum multi-year travel times to the nearest stars are beyond current manned space mission design experience.

Respectfully, you're wrong, Joe. We could leave NOW (well, minus construction time) if we really wanted to. We've had the technology to make a 40ly trip for decades. It's just so expensive as to *seem* impossible.

The limiters are the inefficiency of our recycling, and the lack of collective will.

Considering "2001 a space odyssey" had us going on a manned Jupiter flight with HAL (missed by 16 years at this point), and BladeRunner with flying cars that park on top and inside buildings in 2019 (hurry up!!) - I think our Sci-Fi to reality gauge needs to be re-tuned. 

I pretty sure that we will be waiting a long time before we can travel 40 light years.

Given that the sun's lifespan is half over where do you think space exploration is headed? Are we, humans, looking for a place to colonize before it all goes black? I always wonder that.
