    Some major revisions....

    The use of thin walled cylinders made of aluminum alloy 2024-T3 reduced the Habitat Sphere mass to just 8.2 million tonnes. This affects everything from propulsive energy to heat transfer. Starship Generations will now require just 51 tonnes of antiprotons for acceleration and deceleration to Alpha Centauri, cruising at 1500 km/sec during the 800 year journey. In addition the use of waste heat from agriculture and air-conditioning in the form of a photon rocket will push the starship even faster, saving over 80 years in travel time - therefore the starship will arrive at Alpha Centauri more than 3 generations sooner !

    Over the past few months of continuous development & revision Starship Generations has been reduced in size by 75 percent and reduced in mass by 83 percent. At the same time its antimatter propellent requirement has been reduced by 98 percent, and the mission has been shortened by 3 generations. This took some creativeness to achieve for sure. In the future with the use of more sophisticated analysis I can only imagine how much better the ship's performance could get.

    Wouldn't that be a bummer if they arrive to find a system devoid of habitable planets. Or worse, a hostile alien race on the attack. Why not send a scout vessel first? 10000 seems a large number to risk on a gamble of this measure. 800 years is also an unnacceptable amount of time. Rome rose and fell during a shorter time span, what makes them think that a similar level of activity won't be present?

    Space Traveling in present conditions...

    SpaceTraveling will be possible only if we discover a way to travel faster than light, or if wormholes exists and there is one near enough to be reached (without consider that the chances to come back would be very small...). Anyone will spend 800 years in a spaceship... It's already very uncomfortable spend some hours in an airplane...

    The area we most research is still the area we lack technology... better find out if light is really the limit, and then find out a kind of material that resist this kind of velocity and pressure... !! Better ask for aliens... (I am not kidding...).

    By the time, very nice quote Teg: "Imagination is more important than knowledge". I like all Albert Einsteins'...

    forgot something...

    P.S.: Perhaps we can take a short-cut using another dimension, if we learn how to make the shift...

    One of the things that have always bothered me has been the effect of alien bacteria upon earthly biota. Yes, I am familiar with the argument that being alien to the intended planet that it’s bacteria and other life forms will have no built up dependence in the form of parasitic or symbiosis to it’s hosts. But that is the short-term view.

    In the long term, eventually, there will become pests and assorted other areas of opportunity for those lifeforms that can adapt. We can not being an entire ecology into another world. We can bring some but not all the necessary items to the environment. We can not ensure that the required minerals, chemicals, and conditions will be present to ensure growth of our agricultural foodstuffs. We can not make certain that all desired trace elements that are needed for our survival are present or in the forms most wanted. What if all the sugars present on this new world are right handed in DNA spiral? If it is the case then they are unusable by us for body fuel either for us or for our animals that we depend upon for food. Modifications may well present problems that are beyond the scope of the daring pioneers that attempt this feat. Should such be the case then the colony will perish. We have no way of knowing what such conditions will be until we actually arrive. As such it may well be a martyrs one way trip in attempting to establish a colony.

    Should we, knowing this, endeavor to establish a colony, which will have no way of returning or securing help in the form of needed supplies and materials?
