  1. 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?
  2. 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?
  3. 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? Cheerz GIAN 🙂
  4. 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
  5. 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
  6. 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
  7. 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
  8. At the BIS Christmas lecture in December John Zarnecki spoke about how he and his team designed and built the Huygens probe for Titan from scratch. No wonder it took so long and was so expensive. Why can't someone design a generic spaceprobe which can be used anywhere and built on a production line like Boeing airliners? Has anyone tried this? Cheerz Gian☺
  9. Spoke to Prof John Zarnecki after a lecture he gave about Titan last month and he said that yes astronauts on Titan could use the nitrogen and there would be enough water ice to extract oxygen to make breathable air. He also said that there will be big waves and it will be possible to go surfing on Titan!☺
  10. Science says (I think) we can make artificial gravity in space using a centrifugal force on the inside of a rotating circular structure. If so, anyone know what maths and physics I need to calculate speed of rotation for a given radius of a circular spaceship? Cheerz GIAN
  11. Hydrogen-1 (protium) is an isotope of Hygrogen yeah? It has one proton in the nucleus and one circling electron? So is Protium just another word for hydrogen itself?
  12. THANKS!!!!! Got it (I think) 1/2x1/2=1/4 (viz to the power2) x1/2= 1/8 (to the power3) x1/2= 1/16 (to the power4) x1/2= 1/32 (to the power5) So ans=5 Is there a particular formula I should use though? Or is working through it methodically number by number the right way to do it?
