@article{Chung2000CanGI, title={Can geodesics in extra dimensions solve the cosmological horizon problem}, author={D. J. Chung and K. Freese}, journal={Physical Review D}, year={2000}, volume={62}, pages={063513} }

We demonstrate a non-inflationary solution to the cosmological horizon problem in scenarios in which our observable universe is confined to three spatial dimensions (a three-brane) embedded in a higher dimensional space. A signal traveling along an extra-dimensional null geodesic may leave our three-brane, travel into the extra dimensions, and subsequently return to a different place on our three-brane in a shorter time than the time a signal confined to our three-brane would take. Hence, these… CONTINUE READING
