Do wormholes exist, allowing travel across vast expanses in the blink of an eye? They do within the "fabric" of this crossword's grid. Five wormhole-themed entries require you to begin filling in your answer in one spot and then travel through a wormhole to complete the answer in a symmetrically placed location across the grid.

The puzzle also contains 12 clues related to articles that appeared in Scientific American in 2005--one for each month. Visuals from the referenced articles frame the grid.
