Or do the rules of general relativity absolutely forbid something like this from becoming reality? Physics investigates.<\/p>\n\n\n\n<p>For as long as we\u2019ve been thinking about journeying to other star systems and the planets and worlds that orbit them, we\u2019ve been compelled to consider just how to keep human beings intact during any journey that would bridge the interstellar distances. While short trips through the zero-gravity environment of space might be feasible for humans, over longer time periods, human bodies suffer from all sorts of maladies:\u00a0<a href=\"https:\/\/southwesteye.com\/eye-care\/how-space-travel-affects-eyesight\/\" target=\"_blank\" rel=\"noreferrer noopener\">space blindness<\/a>,\u00a0<a href=\"https:\/\/www.nasa.gov\/missions\/station\/iss-research\/counteracting-bone-and-muscle-loss-in-microgravity\/\" target=\"_blank\" rel=\"noreferrer noopener\">bone density loss<\/a>,\u00a0<a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/10336885\/\" target=\"_blank\" rel=\"noreferrer noopener\">muscle atrophy<\/a>, and much more.
