The wormholes add magnitude to a math parameter called the Gauss-Bonnet term. Boosting one term in a complex equation helps scientists explain how the results could change. Scientists in Greece ...

Brian Greene, professor of physics and mathematics at Columbia University and co-founder of the World Science Festival, explains what we know about time travel so far. Following is a transcript of ...

However, these wormholes differ from those phenomena in significant ways. The mathematics describing their creation requires ...
