Interesting viewpoint. I don't agree but you make some good points. I guess if you are correct we had better just ignore the last eighty years of Space Travel based Sci-fi and know that we will never know what is beyond our solar system. Bummer. The radiation exposure (something that is seldom mentioned is the dose astronauts get in space or how much the crews got going to and from the moon) is a real hazard and without shielding could make space travel very limiting. What is really needed to get beyond the place and space we are in now is a new power source that will replace chemical reactions and allow the next expansion of technology. Until that happens and we are limited to combusting fossil or synthetic fuels for power sources for rockets and aircraft, we will not progress any further. Until that happens the issue is mute, we will not be able to travel much beyond what we have already seen and intergalatic travel will be impossible so maybe you are right after all.
