Why propulsion? Why rockets at all? https://youtu.be/LMbI6sk-62E https://youtu.be/LMbI6sk-62E

    Who said it needs to be soon?

      What you've done is taken a hard unsolved problem and replaced it with an even harder unsolved problem, and you think that constitutes solving the problem.

        I didn't solve any problem, I just demonstrated that a faster horse is not the only option even though the article presents it as such. The physics of orbital rings are understood well for many decades; it just costs a lot and the economy is not there yet. It might not get there if nobody said rockets aren't the only option.

          Real-world engineering realities, tends to throw a wrench at perfect-world physics equations.

            Sure, I didn't say it will be easy, or that it's simple.
