Comment on Light-Speed Spaceships Would Have Trouble Phoning Home

  Ok, then it’s fictional. The theoretical warp drive that is consistent with Einstein’s field equations moves through normal space but just warps it in a way that it effectively moves faster than light (while locally obeying the light speed limit).

  Though that still requires something with negative mass or gravity (I was very disappointed when they confirmed antimatter has normal gravity, I was hoping the theory was wrong on that).

    There’s still dark energy and dark matter that are kinda odd

      There is the idea that everything is shrinking instead of space expanding, which resolves the dark energy question.
