    Today I tell you how my opinion about dark matter has changed an why. Is modified gravity better or worse? What evidence speaks for one side or the other, and is the case really as clear-cut as many astrophysicists claim?

  2. Please Explain: Matter, Anti-Matter, and Dark Matter

    Please Explain is all about matter, anti-matter, and dark matter. Lisa Randall, Professor of Theoretical Physics at Harvard University; Michael Tuts, Professor of Physics at Columbia University and Mordecai Mark Mac-Low, Chair of the Department of Physics at the American Museum of Natural History tell us all about what it is and what it means.

  3. Richard Panek: ‘Let There Be Dark’

    Everything that we know and can sense may only account for a measly 4 percent of the universe. Everything else? It’s dark. Either dark matter or dark energy. It can’t be seen or even sensed by any instrument that we’ve been able to design. So how do we know it’s there?

    Richard Panek answers that question in his book "The 4 Percent Universe: Dark Matter, Dark Energy, and the Race to Discover the Rest of Reality." Panek’s not a scientist, he’s a creative writer, meaning he focuses on the human narrative behind the discovery of the other 96 percent of the universe.

    Richard Panek teaches creative writing at Goddard College in Vermont. He’s also a New York Foundation for the Arts Nonfiction Literature fellow and has received an Antarctic Artists and Writers Program grant from the National Science Foundation. He came to Town Hall on January 25, 2011. His talk focused on the story of who discovered the hidden universe, as well as the science itself.

  4. A Very Dark Matter

    In physics, the darkness is the most illuminating place to look if you want to understand the Universe right now. We now know that 26.8% of all matter is dark. And dark energy accounts for 68.3% of all energy. So nearly 96% of the Universe is dark. It is there; but invisible.

    Our understanding of the dark universe is not just the result of scientific research and technological innovation. Artists have been active in producing some of the most powerful and persistent ideas about the possibilities of of invisible universe we exist within. Just as the cartographers of the past worked hand-in-hand with artists who illustrated and interpreted the new worlds they discovered, the dark universe is being mapped, visualised and sonified by artists.

    Honor’s talk will touch upon how culture can help illuminate the darkness.

  5. Big Picture Science

    Light, the Universe, and Everything — ENCORE What’s it all about? And we mean ALL. What makes up this vast sprawling cosmos? Why does it exist? Why do we exist? Why is there something rather than nothing? Ow, my head hurts! For possible answers, we travel to the moment after the Big Bang and discover all that came into being in those few minutes after the great flash: time, space, matter, and light. Plus, the bizarre stuff that makes up the bulk of the universe: dark energy and dark matter. Also, what we set in motion with the invention of the light blub. How artificial light lit up our homes, our cities and – inadvertently – our skies.
