Feb 4, 2014 — When did it first become possible for life (as we know it) to appear in the cosmos? The answer seems obvious now. But it arrived, unexpectedly, in the shower. It's a story that tells us a lot about how creativity works in science.
Dec 18, 2013 — What was there before the universe began? It's not a question we can really answer with the science we have at hand, says commentator and physicist Marcelo Gleiser.
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.
Nov 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.
Oct 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.
Oct 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.
Oct 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.
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.
Sep 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.
Sep 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 NoŽ asks if we can actually accept this, or if there is more to the universe than the particles and fields of physics.
