@r3cy780 you're talking about the law of diminishing marginal returns. Or to put it another way, picking low hanging fruit. Getting to the moon is absolutely minuscule compared to getting to just the nearest star. If the world was a grain of sand on a beach, and the moon was the adjacent grain of sand, the nearest star would be further than the moon is. The distances are mind boggling. You can fantasise about all the technology you want, in order to achieve speeds that would make it realistic for humans to travel, you would either have to accelerate at such a rate that humans could not survive, or you would have to take so long accelerating that any human would be dead before you reached the necessary speed. And that's assuming you'd harnessed an energy source that would give the unbelievable amounts of energy required to accelerate mass to the speed and the materials to withstand it and keep people safe. A better analogy is ships. Yes we can sail to Australia quicker and a lot safer than we could 300 years ago but it still takes a bloody long time. We haven't been to the moon for 50 years and right now we haven't got the technology to take us there. The only reusable spacecraft we've ever had, the space shuttle, is gone. The only way we are realistically going to explore other stars and world is with robots, and it will take generations to get the results

At that rate in ten generations we might get there in one generation
