October 22, 2014 Is there such a thing as complete emptiness or nothingness? Not according to modern physics, where empty space gets more active all the time, says commentator Marcelo Gleiser.
One way we make sense of the cosmos is to study what's in it, objects like this brown dwarf (artist's impression) observed by the ESO's ALMA project. Another way is to watch what happens when tiny particles are smashed together in "labs" such as the LHC at CERN.
December 5, 2012 Can scientists create universes in the lab? Although that may not be possible, physicists can recreate the young universe in high energy particle collisions. Recent results indicate that the young universe may be stranger than anticipated.
May 22, 2012 We simply can't imagine, as in draw a picture in our heads, what quantum mechanics is pointing us to in terms of a "picture" of reality. We don't have the mental machinery to create images in our heads that embrace the reality our experiments imply.
