Can computers think? Why this is proving so hard to answer
In 1950, Alan Turing proposed a test to tell a human from a computer. Today, that Turing test may tell us more about ourselves than about machines.

A massive rogue roaming our galaxy may be a black hole
Alternatively, this unseen wanderer might be a hefty neutron star. Whatever it is, its gravity caused starlight to be warped — and that gave it away.
