Apocalyptic? Maybe. Possible given the current knowledge and evolution of science in this field? Absolutely.
The solution: As in cosmetics, we need more trials and more tests. More people fucking in space and against walls. In all positions and in all seasons. For pleasure, for the future of the race and for life on other planets. On 20-minute space tourism trips and on long-term missions. With robots, with toys, alone and in communes. For testosterone, for weightlessness and for the toast toast toast. The new frontier of civilizational expansion lies not in advances in spaceships and fuel… but in the wanks of the astronauts of today and tomorrow.
