So many planets and no way to get there. What a bummer!

If there is a god, he/she/it must be laughing his/her/it's a## off at our recent discoveries. First we thought earth was the center of the universe and then we thought our star system was the universe, later we thought the Milky Way galaxy only to discover that the Milky Way is just one of billions of galaxies. But we clinged to the idea that planets were rare, or at least planets that could support life were rare. Now we are facing the evidence that "earthlike" planets are probably a dime a dozen and to add insult to injury we can't get our dirty paws on anything outside our own star's influence in the foreseeable future.

There are a couple of ways to get there, but they would be one way journeys, and also require a largish infusion of $ to start. Generation ships might work, but we would need some experience in our solar system before they would be feasible. Drawback: Slow. Bussard ram jet might work as well. Drawback: radiation? Small size?

Realistically speaking nobody is going to spend hundreds of billions of dollars on one way trips to planets that may or may not be able to support our way of life unless it is the only way to avoid oblivion. We may not even be able to move a substantial portion of our population to Mars when the earth gets too hot.

Wrap our DNA in a bunch of rocks and send them on their way. Maybe put a map in the DNA so once they grow they can see where they originated. |

If we would be able to travel faster than the speed of light, things would be easy...and still...Other civilisations might be so distant, we might not even dream of getting there...And radio signals also travel at the speed of light, so it's kind of hopeless...Our only hope is that an alien civilisation might be that evolved, they can find us, no matter what the distance is... rOZZ Music Pictures |

Interstellar travel has to overcome bone loss due to loss of gravity up 15% on a 200 day mission. It doesnt matter ,if you run marathon in space and reap little on bone loss. A century of travel and you wont be able to stand up at the end of the trip ona alien planet. Maybe a city sized asteroid would make a better ship. Gravity artificially induced at least 10 hours a day in a spinning room to create gravity at 1 g. Radation is a monster that is very hard to overcome more shielding more weight spacecraft are light as possible to launch. |

I'm afraid that any alien civilization advanced enough to find us probably already has and decided we are too primitive to communicate with and not worth the effort and risk they would endure.

You're probably right, Bob. If they observe us first, they'll know enough... rOZZ Music Pictures |
