Your point was fine, don't worry.
10. You can travel in space without dying of radiation sickness.
I do believe this issue is solvable. It may be that the only real value of the popular "electro-whatever field" generally used to protect spaceships will actually be to deflect or absorb undesirable background radiation.
Keep in mind, this is a thread on SF space travel myths. The Apollo program was built directly on the research done with the V2 rocket. So nefarious tech can also be used for good ends.
One of the hallmarks of good science fiction is to take one of these supposedly unsolvable problems and propose a solution. I won't talk about Hollywood because you can probably count on one hand the number of times they got it right. But SF authors have a long history of proposing thing might be possible long before they are. Verne and Wells started us off and lots of others have followed. I'd have to say that 1, 6, 8, and 10 from the original list are debatable. Several theoretical ways have been proposed to make FTL possible. They don't involve going faster than light, but by finding other ways of getting from point A to point B faster than light can. Aliens are not automatically going to be hard to communicate with. We need some common frame of reference and for any intelligent species that will necessitate math, physics and chemistry.
Cheap energy all depends on what we can develop. Right now it seems impossible, but it doesn't have to remain that way. And it is very possible to travel in in space without dying of radiation. We need a certain amount of protection and we need to find more effective and efficient ways than we have now, but you can't discount that we will find something.
SF is supposed to be scientific and optimistic about what we can do AND tell a good tale. It's about pushing the boundaries of what we can foresee while entertaining at the same time. Just look at where we've come in the last 150 years and what they said was impossible that we have actually done and accomplished. Given another 500 or a thousand years, what might we be able to do.
I really have nothing to add to this post at all, other than to say it is the most enjoyable thread I've read in a while, and I've been to many forums lately. I just read it from start to finish and to see it's metamorphasis from the innocent list of 'this isn't possible but we accept it' to the pseudo-scientific explanations of 'this is how it might be possible and you don't know what you think you know' was a fun little ride. I also believe that we already know there is so much about the universe that we don't know, and we understand so much today that we didn't know just ten years ago, that it's really silly for us to take 5o year old theories as gospel at this point. But that is just opinion...I can't really back that up:)
Gravity is not in any way caused by spinning, it has to do with mass (think Moon and tides). In fact, spinning ships would be a scifi myth.Quote:
2. You can have artificial gravity without spinning the ship.
