“A Higher Dimensional Universe?” is copyrighted by Mark Newbold. NASA has permission to show it and we don't, so it isn't on this card.
See it on NASA's siteSome astrophysicists hypothesize that our universe has extra dimensions beyond the four we experience. This idea helps explain why distant parts of our universe appear similar and why its geometry doesn't naturally align with the matter it contains. One theory, called the Ekpyrotic universe, suggests our dimensions arose from a collision in a higher-dimensional space.
