It doesn't make sense to me that light could ever reach us from a galaxy moving away from us faster than the speed of light. But this video says that it can happen. Is this true? Could someone explain how it is possible?

  • Your title didn't match your question. I've edited the title to make it consistent with what you're asking. – Jim421616 Nov 02 '21 at 18:39
  • @Jim421616 I understand how galaxies outside the Hubble Sphere can recede from us at faster than the speed of light due to the Universe expansion. I just don't understand if and how light from those galaxies can then reach us. I am going to rollback your title edit. – Connor Garcia Nov 02 '21 at 18:44
  • You're quite welcome to roll back the edit, but my point was that the title asks one question, and the body asks another question. Better to have the title as a summary, and put both questions in the body. Better yet, post two separate questions. – Jim421616 Nov 02 '21 at 18:47

  • Yes, we can most definitely see galaxies with recession speeds exceeding the speed of light. See this answer. – pela Nov 02 '21 at 20:08

    @pela Yes, the answer you linked is exactly the answer I was looking for. I think that may make this question a duplicate. Perhaps I should close it. – Connor Garcia Nov 02 '21 at 20:39
