Nov 20, 2013 — Life on Earth is connected to the stars in ways we couldn't imagine a thousand years ago. Physicist Marcelo Gleiser says the journey to understanding our relationship with the cosmos has transformed how we see ourselves and all that surrounds us.
Sep 29, 2013 — Can everything that happens in the universe (like the working of your mind) be understood merely as an expression of interactions at the level of elementary particles? Astrophysicist Adam Frank doesn't think so. He's skeptical of reductionism and takes heart from a new theory that sees cause-and-effect flowing both ways.
Aug 5, 2013 — Gravity has long worked to keep us from understanding our place in the universe. You, however, can do something about that. Go find a dark, comfortable field and lie down. Soon your perspective on the stars, and our place among them, will shift, altering your view of the universe forever.
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.
