If we can solve the difficulty(cost) of getting things into orbit. Then radiation won’t be that great of a hurdle.
Or we can just send out robots. Which is what we’re going to do anyways.
I agree.
It is going to take centuries, and probably millennia, to figure out how to keep human beings alive, let alone comfortable, in deep space, or on other planets or moons.
And that just solves the space travel problems in our own Solar System.
Visiting other star systems means solving the speed of light problem, if that is even possible.
And the final problem - how do you make money once you leave the Earth, and where can you spend it if you do make it?
Economically, going into space is like going back in time to 10,000 BC.
Except in 10,000 BC they had free oxygen, free gravity, free atmospheric pressure, free firewood, free animals for food and clothing, free water, and free nuts and fruit.
“Or we can just send out robots. Which is what we’re going to do anyways.”
I have speculated that what folks among the UFO set always describe as the “Grays”, could possibly be not the actual beings that built and send the UFOs here, but something like “biologically constructed” and programmed “robots”, engineered to withstand the riggers of the super-long voyages and the dangers of radiation. Why biological and not mechanical? It is likely easier to make a biological construct able to do self-repair than it is to make a piece of metal self-repair. The biologic robots can then also make needed “mechanical” repairs to elements of the ship showing harm from radiation. Yea, just my own silly fantasy I know. LOL
