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.
Apr 30, 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.
Apr 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.
Apr 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.
Apr 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.
Mar 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.
Mar 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.
Feb 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.
Feb 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.
Jan 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.
