“The Hopi, an Indian tribe, have a language as sophisticated as ours, but no tenses for past, present and future. The division does not exist. What does this say about time? Matter, that thing the most solid and the well-known, which you are holding in your hands and which makes up your body, is now known to be mostly empty space. Empty space and points of light. What does this say about the reality of the world?”
![“I've used the Phoenix Centrifuge to replicate what the body's going to go through on the flight up. I've also done some gravity tests with ZERO-G [a charter-flight service in Arlington, Va., that uses modified Boeing 727s to simulate weightlessness], which went great.” quote by Richard Branson](https://sms4smile.com/quotes/img-quotes/aa1/richard-branson-256_adventure_i-ve-used-the-phoenix-centrifuge-to-repl_903.jpg)
