  1. If microbial life is discovered in Venus' atmosphere, and samples are collected, will science be able to tell us whether its ancestry somehow found its way there from Earth, or whether it's definitely a product of abiogenesis on Venus? Thanks GIAN πŸ™‚
  2. Thanks Swansont. What is 'displacement?' πŸ™‚
  3. Apparently the Orion Project for nuclear powered spaceflight asserted that by this method with an acceleration of 1G an Orion spaceship could attain a speed of 10% of the speed of light (c.) Mathematically, how do I work out 1. the length of time it would take to get from 0 to a speed of c/10 (ship's time,) and 2. what would be the distance travelled in that time? Cheerz GIANπŸ™‚
  4. I picture explorers creating giant igloos to use as greenhouses, with methane-powered heating to room temperature and melting water ice for crops and pasture, and also extracting oxygen from water (electrolysis?) to make breathable air. But yes I suspect there wouldn't be enough 'goodies' on the Titanian surface to grow stuff, so the astronauts would have to bring their own compost. Can you define magnetosphere and explain why it would be a problem for animals please? (I'm a novice at science) Thanks GIAN πŸ™‚
  5. When explorers eventually reach Titan, I suppose they could take some farm animals with them which if they had enough to eat would create manure, although I'm not sure how pigs and cattle would get on in the low gravity (flying pigs?) But would there be enough minerals lying about on the surface to use as soil to grow crops? Would there be enough nutrients in it? Titanian wheat and potatoes?πŸ™‚
  6. On the other hand, could biology one day become machines? Eg, scientists could design biological organisms to do what machines do for us now? A biological motorcar which can drive passengers around on wheels at upto 100mph but also eats grass for fuel?
  7. The natural human lifespan has extended from the lifespan of the first life forms. Is the extension of lifespan a natural consequence of evolution and will it continue? What I mean is, is it at least possible with natural selection that vast organisms something like dinosaurs could evolve again?
  8. Three questions 1) If the first life forms c 4y.billion ago lived about 24 hours (?) and we now live about 80years, in another 4y.billion will life expectancy continue to increase in a straight line and our descendants will have lifespans of 2.5y.millon?? If so it will certainly make intergalactic travel more practical! 2) Is our species H.Sapiens continuing to evolve? Will our descendants become a new species or species? 3) Will the natural course of evolution without human agency cause the dinosaurs or something like them to evolve again in the far future?

  9. If we can create nuclear bombs 1000x hiroshima, wouldn't it be fairly simple to use it to power space ships which could accelerate to the point where a trip to the outer planets would take days rather than years? Is it true that this is already quite possible, but governments won't let us do it because of the potential dangers of nuclear accident? Cheerz GIAN xx
  10. inow and swansont Well yes, hopefully sunlight could be turned into energy in another form eg motion and/or light. Yes there would be waste heat but presumably not as much as if the sunlight energy had not absorbed at all. And yes a percentage of the 'harvested' sunlight would also be reflected away from the Earth. Presumably if if it was done on a big enough scale there would be a net cooling of the Earth, plus an additional reduction of CO2-producing forms of energy production? cheerz Gian
  11. If there were enough solar panels installed across the world, besides give us lots of cheap energy would this also reverse the effects of global warming? If so, how many would be needed? cheerz Gian
  12. Cheerz Mr Strange. Well at least someone could produce a generic basic probe with additional components which could be added as required according to the nature of the mission. Thanks for the SpaceX tip I'll check them out GIAN x
