Big Picture Science for 09/02/13 - Catch a Wave

Big Picture Science - Catch a Wave

ENCORE: Let there be light. Otherwise we couldn’t watch a sunset or YouTube. Yet what your eye sees is but a narrow band in the electromagnetic spectrum. Shorten those light waves and you get invisible gamma radiation. Lengthen them and tune into a radio broadcast.

Discover what’s revealed about our universe as you travel along the electromagnetic spectrum. There’s the long of it: an ambitious goal to construct the world’s largest radio telescope array … and the short: a telescope that images high-energy gamma rays from black holes.

Also, the structure of the universe as seen through X-ray eyes and a physicist sings the praises of infrared light. Literally.

And, while gravity waves are not in the electromagnetic club, these ripples in spacetime could explain some of the biggest mysteries of the cosmos. But first, we have to catch them!

Guests:

• Anil Ananthaswamy – Journalist and consultant for New Scientist in London
• Harvey Tananbaum – Director of the Chandra X-Ray Center, located in Cambridge Massachusetts at the Smithsonian Astrophysical Observatory
• David Reitze – Executive director of the Laser Interferometer Gravitational Wave Observatory (LIGO), California Institute of Technology
• Albert Lazzarini – Deputy director, LIGO, California Institute of Technology
• Alan Marscher – Professor of astronomy at Boston University

This encore podcast was first released on March 19, 2012

Are We Alone for 10/26/09 - Skeptic Check: Mind Your Body

Are We Alone - Skeptic Check: Mind Your Body

Popping a pill may help when you’re sick… but maybe not for the reasons you think. Sugar pills – placebos – cure illness better than prescription pills in as many as half of all cases in clinical trials … and the placebo effect is getting stronger.

Plus, the safety – or otherwise – of electromagnetic waves, and the “electro-sensitive” refugees who have built a camp to protect themselves from waves they say are causing pain. Is it all in their minds?

And, New York Times reporter Dennis Overbye joins Phil Plait on the latest lapse in critically-thinking brains – a wild idea that may not be so loony: namely, could a cosmic censor from the future be thwarting efforts to find the Higgs boson?

It’s Skeptic Check … but don’t take our word for it!

• Dennis Overbye – Cosmic Affairs Correspondent, New York Times
• Phil Plait – Keeper of the skeptical website badastronomy.com and author of Death from the Skies!: These Are the Ways the World Will End . . .
• Steve Silberman – Contributing editor, Wired Magazine, author of “The Placebo Problem” in the September 2009 issue
• Leeka Kheifets – Epidemiologist, School of Public Health, University of California, Los Angeles
