Humans haven't even united on THIS planet yet, and now we want to go about visiting other planets with life?
Remember when the Europeans stole land and resources from the Native Americans and forced them to relocated and assimilate into "their" culture?
Wouldn't surprise me one bit if we're doing this same thing to life on other planets 500 years from now. |

Man, talk about pessimistic. With your attitude we'd never crossed the Atlantic ocean, gone to the moon or any of man's greatest achievements. |
Really bad analogies. The distances are not comparable.
A species able to traverse from star system to star system would have godlike powers. You're right, I don't think technology alone can bridge this gap.
I think sci fi has made the all but completely impossible look all too easy. |
Never say never. We won't be alive for it, but you can't write it off. |
Steelrails, has anyone told you before that you have mediocre reading comprehension skills? Where in my post did I say 'never' or 'write off' the possibility? I am taking a strongly pessimistic view on this. But travel to other worlds is conceivable, just extremely unlikely within the next 500 years.

You say that with hindsight. I'm not saying it's happening for our generation or another couple but your completely dismissal of the idea I think is premature. I can write this with my mobile phone on the internet. Try explaining that to someone a 100 years ago.... |
Again your analogy is off. You're comparing my pessimism with the pessimism of someone who can't imagine mobile phones. But light-speed travel and warp-drives and interdimensional travel has already been imagined, and regularly assumed in works such as:
Star Trek, Star Wars, Dune, Alien, Firefly, War of the Worlds, Buckaroo Bonzai, Ender's Game, Space Rage, Howard the Duck, Predator, Space Balls, Contact, etc.
Trust me, I do not lack the imagination. Quite to the contrary, the optimists lack a real appreciation of the challenges. |

Actually Firefly did not have warp drive...
And the other is just hilarious. Ludicrous Speed! |

Rather than trying to accelerate a mass to light-speed, why not use gravity to bend spacetime and bring your destination to you? A sufficiently strong gravitational field will warp spacetime to the degree that the distance between you and your destination will become less (or even zero).
This is the most plausible theory I have heard for being able to cross vast distances in little time, and does not violate relativity laws.
Of course - we don't know that the particles that generate gravity (gravitons) exist yet, much less are we able to gather and use them to generate additional gravity, but to me it sounds much more plausible that trying to accelerate a massive spaceship to lightspeed and beyond. |

See, thinking outside the box. I'll be off this rock in no time. |

Depends on what the planet is made of. Mass determines gravity, not size. So, if it's 3.6 times the size of the earth, but made of material 1/3.6ths as dense, then it would have the same gravity as earth. If it were the same density as earth, it would have 3.6 times the mass and thus 3.6 times the gravity. It's possible that it could even be quite a bit less dense than earth and have less gravity.
Also, 3.6gs is quite uncomfortable, but tolerable. Dragsters can reach up to 5.3gs. If you're in good health, and have some practice at it, apparently you can not black out up to around 10gs.
If you could take it, you'd get pretty beefy working in a 3.6g environment all the time! |

Exercising in that kind of environment at a high altitude (to take advantage of the low oxygen content), then coming back to Earth and competing in your sport at sea level would put you at a huge advantage!  |
