Dark Energy is causing the expansion of the universe to speed up – and not to slow down as everyone expected. This discovery overturns astronomers’ ideas about the history and the fate of the universe. Professor Brian Schmidt describes the discovery that won him the Nobel Prize in Physics last year.

The Best of Ideas - Spinoza
Baruch Spinoza was a 17th century lens grinder known for his precision optical work. But it was his philosophy that made this Dutch-Jewish thinker famous, then and now. IDEAS host Paul Kennedy explores how Spinoza’s thoughts on God, the universe, ethics and politics helped ignite the flame that became the Enlightenment.

Big Ideas: The Importance of the Higgs Boson
The recent discovery of a new subatomic particle, believed to be the long-sought Higgs boson, was hailed as one of the biggest announcements in physics for a century - as a human achievement which will be known 300 years from now. The Higgs Boson is the final missing ingredient in the Standard Model of particle physics. This model describes the fundamental particles from which every visible thing in the universe is made, and the forces acting between them. Listen to the scientists at the level of the experiments which led to this discovery.

Paul Davies: Are we alone in the universe?
Is intelligent life trying to communicate with us from space? Professor Paul Davies explores the potential and limits of research into the origin and evolution of life, and the search for life beyond Earth. Has ET maybe visited our planet ages ago and left us a message? At the Australian National University, Paul Davies discussed his latest book The Eerie Silence: Are We Alone in the Universe?

The Quest for Immortality — FastForward Radio
Hosts Phil Bowermaster and Stephen Gordon discuss the quest for immortality, which has been with humanity for a long time — perhaps since the very beginning, and which has done much to shape the world in which we live. New organizations are emerging with a whole new take on the proposition that life can be extended indefinitely.
How do we get from here to there? The phases might look something like this:
Life Extension
Durable Digital Replacements
Substrate Mobility
Immortality
So, will some of us live forever? And what does that even mean?

Neil deGrasse Tyson On Exploring Cosmic Frontiers
http://www.sciencefriday.com/program/archives/201203024
Many of us spend more time at our desks than anywhere else. Astrophysicist Neil deGrasse Tyson takes us into his office at the Hayden Planetarium in New York City for a tour of his office, in the fourth of Science Friday’s Desktop Diaries series. From a Saturn lamp Tyson made as a kid to his van Gogh pillow, Tyson has a lot of universe-themed paraphernalia. Tyson highlights some of his collection, and talks about what his journey to science stardom has been like.

In Space Chronicles: Facing the Ultimate Frontier, astrophysicist Neil deGrasse Tyson writes of how space exploration — especially human voyages — can profoundly inspire scientists and technologists of the future, and charts the path for missions to Mars and beyond.

Cosmos: It’s Big, It’s Weird
It’s all about you. And you, and you, and you and you… that is, if we live in parallel universes. Imagine you doing exactly what you’re doing now, but in an infinite number of universes.
Discover the multiverse theory and why repeats aren’t limited to summer television.
Plus, the physics of riding on a light beam, and the creative analogies a New York Times science writer uses to avoid using the word “weird” to describe dark energy and other weird physics.
Also, people who concoct their own theories (some would say fringe) of the universe: is all matter made up of tiny coiled springs?
Guests:
Brian Greene – Physicist and mathematician, Columbia University, and author of The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos Dennis Overbye – Reporter, New York Times Simon Steel – Science educator at University College London Margaret Wertheim – Science writer, author of Physics on the Fringe: Smoke Rings, Circlons, and Alternative Theories of Everything

Lisa Randall: Physics, Science, And The Universe
If you care about the big questions of the physical world, then Lisa Randall would be great company at a dinner party. Over drinks, the Harvard physicist could tell you what we know and don’t know about particle physics and cosmology.
During dinner she’d use poetry to describe the Large Hadron Collider – the biggest machine ever built – and the mysteries it could soon reveal. And with dessert — a passionate argument for the value of scientific thinking and what we lose when we put faith over logic.

Deepak Chopra and physicist Leonard Mlodinow: Science And The Spirit
Deepak Chopra and physicist Leonard Mlodinow join us to talk science and spirit.
America was built on science. America was rooted in religion. For 200 years, both thrived. In the last quarter-century, they’ve clashed. And the clash has been costly.
Can we settle this? Maybe. We’ve got two big figures with us today who have taken on the war of worldviews.
Man of spirit, Deepak Chopra. Man of science, Leonard Mlodinow. One a giant in the realm of spiritual guidance. One a Stephen Hawking-scale master of physics and the scientific way.
Both ready to hash it out.
