November 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.
November 6, 2013 The hunt for dark matter started in the 1930s and shows no signs of ending any time soon. But physicist Marcelo Gleiser says our inability to pin down this key component to reality only makes it more alluring.
October 29, 2013 Carl Sagan, an astronomer with the soul of a poet, liked to remind us that we were all made of "star stuff." It was, without a doubt, one of his most beautiful images. Astrophysicist Adam Frank says it's not just an abstract concept; you can reach out and feel it in the space dirt covering your ride.
October 22, 2013 Science is radical and conservative at the same time, almost as if it exists in a quantum state. Commentator and astrophysicist Adam Frank says this is the tension at play today as his community struggles with whether to keep faith in the laws that determine the one universe we see or jump ship for the promise of the multiverse.
October 16, 2013 The Earth has existed for nearly 5 billion years and, to this point, no other forms of life have been identified in the seemingly boundless expanse of outer space. Commentator Marcelo Gleiser says this simple fact has deep implications for who we are and how we should treat life here on our home world.
September 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.
September 17, 2013 Science, at its most fundamental level, is about telling the story of all that is around us. In this installment, astrophysicist Adam Frank tells the story of the stellar wind and the bubble that Voyager has just exited on its journey into interstellar space.
September 13, 2013 We find ourselves drawn to the belief that physics alone investigates the basis of the universe, reality as it really is, beyond parochial human interests and values. Alva Noë asks if we can actually accept this, or if there is more to the universe than the particles and fields of physics.
September 11, 2013 We know a lot. But we don't know everything. In fact, science still has quite a few "big" questions left to answer. Physicist Marcelo Gleiser pokes at 10 of them, questions highlighted in a new book naming the most difficult scientific problems of our time.
September 10, 2013 Chaos rules the universe. But life fights back, nurturing order and structure within the maelstrom. Astrophysicist Adam Frank says that our struggles against the inexorable forces of entropy are a gift to the cosmos.
September 4, 2013 Astronomers have found younger and older twins to our sun, giving us a peek at our mother-star's past and future. Physicist Marcelo Gleiser says it's hard not to wonder what kind of life an older solar system might harbor and how similar, or different, it would be from us.
August 13, 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.
June 5, 2013 Last week NASA scientists put the space telescope Kepler in a kind of technological coma. The craft, designed to search for Earth-like planets orbiting stars in our cosmic neighborhood (within a few thousand light-years, that is), failed and seems to be unfixable. But it has left us with an undeniable legacy.
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.
