20Km dia has nothing to do with gravity. Gravity is dependent on mass not size. It depends on what that 20km dia globe is made from. Think 20m globe of balsa wood vs a 20m globe of pure lead.At first I liked the idea of the globe ship. Some of the others have weird appendages which can only be explained as fantasy extensions to only look fierce! I.e. No practical purpose. Given a globe though, say 20Km dia. what gravity would it exhibit (w/o any gravity generator - whatever that is)?
We know how to produce simulated gravity. Think 2001 A Space Odyssey (1968). Aside from that film there are quite a few films that use spin for simulated gravity. The problem with humans in space is not gravity, its radiation exposure over duration. The ISS is very close to Earth. Close enough to still be protected a bit by Earth's magnetosphere.No use drawing spacecraft designs until we know how to produce gravity. Humans need constant g to survive any reasonable length of time. Take Startrek, they must have some sort of g generator under each floor. Has it ever been mentioned?
I've read actual NASA articles where the astronauts describe seeing pinpricks of light flashes while in space, but it has nothing to do with gravity.I think I have seen an article where retired astronauts have eye problems due to being exposed to no gravity. Anyone heard about this?
"First, it is important to note that the human race is not even on this scale yet. Since we still sustain our energy needs from dead plants and animals, here on Earth, we are a lowly Type 0 civilization (and we have a LONG way to go before being promoted to a type I civilization). Kaku tends to believe that, all things taken into consideration, we will reach Type I in 100 – 200 years time."I guess we are just coming out of Neanderthal period of Space travel.
It is awesome, I finished series, I saw it for free, at my friends house.The ship reminds me of 2001, the only bad part of the series is it is over and I cant wait until next year....
1960s era sci-fi? Simple, they had gravity shoes and boots. Propulsion was main thrusters aft. Retro rockets provide, pitch, roll, yaw axis control. , Thank you, thank you..... Sci-fi dude, rah, rah, rahhhhh..LOLMind telling me how this spacecraft manoeuvres? Does it have gravity?
