There are many outstanding books explaining the latest developments at the frontiers of theoretical physics to general audiences. This is not an easy thing to do, but the physicists who have stepped up tend to be very good writers and expositors: I am thinking of people like Roger Penrose, Julian Barbour, and Lee Smolin. 897 more words

#### Black holes are 'portals to other universes,' according to new quantum results

Black holes may not end in a crushing singularity as previously thought, but rather open up passageways into whole other universes.

According to Albert Einstein’s theory of general relativity, black holes are uninhabitable chasms of spacetime that end in a “singularity,” or a mass of infinite density. 657 more words
