Neil deGrasse Tyson: There Is No Center of the Universe
If the universe is expanding, can we use the direction of the expansion to determine the center of the universe, i.e., where the Big Bang happened? In a word, “No.” Find out why when astrophysicist Neil deGrasse Tyson and comic co-host Eugene Mirman answer a fan’s Cosmic Query in this StarTalk Radio “Behind the Scenes” video.

Flow Battery Could Store Wind, Solar Power For Later Use
A big roadblock for renewable energy like solar and wind is that sometimes the power isn’t there when you need it (like at night) or there’s too much (like a windy day). Researchers at Harvard believe ‘flow’ battery technology could solve this issue.

How NASA’s Creating The Coldest Place In The Universe
Researchers are trying to create the coldest spot in the universe. Why? Because they can! Also, because it can teach us a lot about quantum mechanics, and we could study what happens to light and matter on an atomic level. Anthony breaks down how creating a really cold place could potentially teach us more about the governing laws of the universe.

Neil deGrasse Tyson & Brian Greene Reenact a Scene from “Gravity” at StarTalk Live
What would really have happened in the Oscar winning movie “Gravity” when George Clooney cut himself loose from Sandra Bullok? Find out in this re-enactment starring astrophysicist Neil deGrasse Tyson as Sandra Bullock, physicist Brian Greene as George Clooney, and Eugene Mirman as “The Space Station.” Co-starring Michael Ian Black as “the man with the theory” and NASA astronaut Mike Massimino as “the only guy on stage who has actually been into space.” (This recently unearthed video was shot at StarTalk Live at Town Hall in NYC on Nov 4th, 2013 by Stacey Severn.)

Where Does Energy Come From? | Martin Archer | Ask Head Squeeze
This week on #AskHeadSqueeze Thursdays, Martin Archer answers a question from CuttlefishPi on our Head Squeezers Google+ community. Where does Energy Come From? Martin reckons this is really three questions - let’s hope he’s got the energy to tackle them all.
00:46 Where did the idea of Energy come from?
The concept of energy, and its name, probably comes from Aristotle and the ancient Greeks and they’re word energeia. Gottfried Leibniz came up with something like the modern concept of energy with his vis viva or living force in the 1670s and 80s. But the idea of energy didn’t really catch on until the 19th century with the advent of thermodynamics and reformulating of Newton’s laws of mechanics.
01:32 What is the energy in the Universe?
There are loads of different types, but they can generally be lumped into two categories. Kinetic energy is all about motion, and even heat is included in this broad group. The other category is potential energy, which you can think of as stored energy. One of the amazing realisations of the 20th Century was that matter itself is simply highly condensed energy - energy that can be released, as in a nuclear bomb. But energy can’t be created or destroyed, it can only change form.
03:59 Where does energy come from?
At heart, energy is an abstract concept. But the concept exists because of time symmetry. In 1915 German Mathematician and Theoretical Physicist Emmy Noether proved that if the laws of Nature have a symmetry then there must be a physical quantity which is conserved. She showed that energy is a consequence of the fundamental time symmetry of Nature, without this symmetry energy would not exist and nothing would exist.

Using Magma To Create Energy
Iceland is leading the way when it comes to using magma as an alternative source of fuel. In fact, they even came up with the first ever geothermal plant after accidentally drilling into magma back in 2009! Trace explains how this new power plant is changing how we heat our homes in hopes for a more sustainable future.
