Do i want to go to space in general? yes. Do i want to go into space if there is nothing? No.
I mean breakthroughs in like technology which brings us to mars in an hour and to other galaxies. A signal of motivation to explore space itself.
The fact that it is there and that only a tiny tiny fraction of it has been explored is reason enough.
> if there is nothing?
How can you know there is nothing without actually exploring first?

These don't happen magically. The work has to come first and breakthroughs happen as people live and work in challenging environments.
