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.
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 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 20, 2013 Can science explain the origins of the universe, of life and of the mind? Not completely, it turns out. But how far can it go in answering them? Commentator Marcelo Gleiser starts digging into these questions.
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 29, 2013 Is your Mind real, or just an afterthought in the life of your brain? What if the Mind was something as real as Space and Time and Higgs Bosons?
January 15, 2013 In a breathtaking video, astronauts talk of the Overview Effect: how their vision of the Earth — and our role in its future — changed once they saw it from space. It's high time we take their views seriously and act as a species to preserve our future.
