A Galaxy-spanning network of wormholes could conceivably allow one to step through to not only anywhere, but anywhen. So far, spacetime wormholes are only studies as mathematical solutions within Einstein's theory of general relativity-the modern theory of gravity as a curvature of spacetime. There is today no observational evidence that wormholes exist in our universe. Theoretical physicists have found that wormholes large enough for a starship, a person, or even a single atom to pass through are unlikely to exist. Wormholes are inevitably associated with exotic types of matter such as strongly negative mass.
Physicists are also interested in microscopic wormholes, much smaller than a proton.
These might play an important role in quantum gravity, where spacetime is viewed as a foaming sea of tiny wormholes, forming and disappearing every instant. All science involving wormholes is highly speculative. It is worthwhile because it involves applying Einstein's theory to the most outrageous conditions-where it is most likely to fail, and, in doing so, lead us to new insights about gravity and the geometry of reality. Two teams for the March 2000 Reduced Gravity Flight Opportunities were selected from Montana State University. That's two more Vomit Comet teams.
