But you didn't show up! So I could explain why I always tell the truth, which has made me rich, healthy and popular and in good shape. And unpopular with twerps who disagree with me.
You wanted to discuss space travel. IMHO only a one-way robot/instrument orbital flight around Earth is feasible. Any findings by the instruments must then be relayed electronically down to Earth. The rest is BS. Just the radiation fields in low Earth orbits will kill any human being there at once but, regardless, there is no way to brake, re-enter and land on Earth again. So USA and Russia decided to fake it all 60 years ago and there we are today. I explain it better at

It seems cosmologists like Steven Hawkings have just invented everything in space because the only instruments they had were in low EPO and whatever results they received were adjusted to suit their fantasies. I find it fascinating. Wasting your complete life with such nonsense.
My life has been much more interesting inspecting and repairing seagoing ships all over the world and meet real people.
