May 22, 2013 Confronted with the amazing advances made by science, why do so many still cling to God as a creator? Could the answer be that we need to be created in order to be special? Or are we afraid of our own unique place in the Universe? Marcelo Gleiser knows what he thinks.
May 2, 2013 Time is special. How we see it helps determine how we see the rest of the Universe. Physicist Lee Smolin has a new book out that says we've been looking at time the wrong way. Adam Frank digs in and offers his own perspective on Smolin's argument.
April 17, 2013 Is the importance of life on Earth shrinking as science continually re-defines our world as a meaningless speck in an endless and uncaring Universe? Or is life here a precious thing that grows in importance with our ever-deepening knowledge of the Universe? Commentator Marcelo says it's the latter.
April 16, 2013 Scientists can't just agree to disagree. It's not because we are stubborn or ornery (OK, maybe we are). It's because science faces a fundamental problem when it can't agree on numbers like the value of the Hubble Constant. The whole point of science is to establish an understanding of the cosmos on which we can all agree.
April 10, 2013 Science discovers one dark material after another, making reality stranger than fiction. Commentator Marcelo Gleiser says the recent observation of the Higgs field and last week's announcement of the possible detection of dark matter are just the latest data points in our long quest to know what the Universe is made of.
March 27, 2013 Can science ever explain the origin of the Universe? Commentator Marcelo Gleiser suggests caution and humility as scientists face this very difficult question.
March 21, 2013 Results from the European Planck satellite point to an older and slower universe. Commentator Marcelo Gleiser says the data gives us confidence that cosmology is on the right track to explain the Universe in which we live.
February 27, 2013 The Universe could end tomorrow, courtesy of the newly-discovered Higgs. But, as commentator Marcelo Gleiser explains, there is really no need to panic.
February 20, 2013 The Universe is different from the universe in commentator Marcelo Gleiser's eyes. It's not about grammar. It's about cosmology, about what we know versus what we are able to imagine.
January 9, 2013 Modern cosmology predicts the existence of other universes. But can such idea be tested? And should we worry about universes colliding? Yes! Welcome to the world of cosmic catastrophism.
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.
October 12, 2012 Can natural science find a place for us in its vision of the cosmos? Thomas Nagel, in a new book, demands we take this question seriously. He is right to do so.
October 10, 2012 In this idealized dialogue between faith and science, some of the most entrenched reasons for the common split are explored. Science insists in the reality of things, faith doesn't. Science measures, faith believes. How to deal with the origin of the universe?
October 7, 2012 In the 17th century, an Irish bishop famously concluded that the universe was created on October 23, 4004 BC. Scientists know that our universe, and our Earth, are much more ancient than that. Not everyone agrees, even in the year 2012.
October 3, 2012 In 1543 Copernicus moved the Earth from the center of the cosmos to a less exalted position. In 1924 Hubble did it again, moving our galaxy from the center of the universe to its place in the crowd. Are we on the verge of realizing our universe also is just one among many?
