INTRO: Unusual flashes of gamma rays could reveal that what appear to be giant black holes are actually huge wormholes, a new study finds. Wormholes are tunnels in space-time that can theoretically allow travel anywhere in space and time, or even into another universe. Einstein's theory of general relativity suggests wormholes are possible, although whether they really exist is another matter.

In many ways, wormholes resemble black holes. Both kinds of objects are extremely dense and possess extraordinarily strong gravitational pulls for bodies their size. The main difference is that no object can theoretically come back out after crossing a black hole's event horizon — the threshold where the speed needed to escape the black hole's gravitational pull exceeds the speed of light — whereas any body entering a wormhole could theoretically reverse course.

Assuming wormholes might exist, researchers investigated ways that one might distinguish a wormhole from a black hole... (MORE)

The very idea of a "hole in space" is pure nonsense. That is pure "fantasy"! It cannot be called "science fiction" because there is no "science" in it since it is impossible to create a hole in the empty void of space.
