And fuels to achieve this as well. The only way we could keep traveling is with the slingshot system that is utilized for unmanned space probes now.

How would we know with certainty where to aim for and how to do those calculations infinitum?

Would we choose the right pathways to leapfrog round planets by slingshoting around them indefinitely?

Solar energy is limited to being close enough to a star to use that energy source and as we leave our solar system then we suffer the same limitation.

Anyone trying to visit us would too.
