Lifespan can be twenty years and there still is no problem. Not sure what part of this you are not getting. No one is saying the individuals who set out will get anywhere special other than closer. Descendents will get there.

And I think plenty of people would want to go, things don’t have to get bad here on earth. Lots of people don’t leave their city for years, wouldn’t mind never leaving it. If the craft is the size of a city, they wouldn’t even notice a difference.

And if your name was Denis you would be having much more sex – probably constantly at first - Groucho. Dennis, your numbers make sense. Fox was just stating that there are 176 million combinations of Mega Millions numbers, times one dollar each. The jackpot is 670 million, so it would be worth it to buy every possible combination of numbers. I remember someone had several people buying numbers for him at supermarkets in Pennsylvania and they bought several hundred thousand tickets in the time available and he won! But with a lot of complaints from people in line who were never able to buy a ticket, and there were some rules changes.

So why not take a small mineral and water laden asteroid or small planet on a trip? Why not genetically engineer humans to be smarter, saner, and with longer lives, for the Grande Voyage? There are ethical considerations but that has never stopped progress. The wonder and the quest is the major consideration.

Reaching any specific star is unimportant - the gold is the trillions of smaller bodies between the stars.


What smaller bodies. One past the Oort cloud, then what? The space between stars is mostly empty. And what will be the energy source. Once one is far from the Sun and not near another star where shall the heat come from? There is just so much fuel that can be carried in a vessel.

The Oort cloud extends out about a light year:

http://en.wikipedia....wiki/Oort_cloud

After that you have the parts of the Oort cloud ejected - trillions of bodies, various planets and moons ejected during solar system(s) formation [hundreds of sizable bodies], various failed stars and bodies too small to form stars - dozens of large bodies and billions or trillions of smaller ones. Hopping from body to body provides all the ingredients you need for fission/breeder fission/hybrid fission-fusion/fusion for billions of years worth of fuel on hundreds of trillions of locations.

Each vessel need not travel far and there is plenty of nuclear fuel and volitiles for propulsion. There are billions refueling stations in every direction well within known propulsion techniques -even those tested in the 1960's. Take 4.3 light years divided by millions or billions and you aren't traveling far. The stars aren't of much value except to tell you where the smaller bodies are clusters. Heat rejection - not cold is the issue in space as discussed in a previous post and on Ice_Station at YahooGroups.

It also means that direct electrosynthesis of starting foodchain stuffs for space
development can be done without sunlight or other hinderances. As deep sea
vents have shown once you set a few nutients and chemosythesis going a whole
food chain can flow from there.

We can put the ARI in a starship.

I just noticed that none of these habitable planets is in the Romulan Neutral Zone. What's up with that??
