Questions, questions, questions...
1) Is the Orion drive really stupid ?
Only as stupid as your ugly face.
2) What's going on with Tabby's Star ?
3) Shouldn't Dyson spheres be resistant to heat and hard to detect ?
4) Could the ISS catch an astronaut if their tether broke ?
5) Could the dimming of Tabby's Star be due to comets or sunspots ?
I dunno. Maybe.
