Radio broadcasts leave Earth at the speed of light. Scroll away from Earth and hear how far the biggest hits of the past have travelled. The farther away you get, the longer the waves take to travel there—and the older the music you’ll hear.
A Black Hole Mystery Wrapped in a Firewall Paradox - "A paradox around matter leaking from black holes puts into question various scientific axioms: Either information can be lost; Einstein's principle of equivalence is wrong; or quantum field theory needs fixing." [more inside]
Brian Greene's Fabric of the Cosmos is online in its entirety on NOVA's website, in four one-hour episodes. Time, Space, Quantum Mechanics, Multiverses.
The concept of time as a way to measure the duration of events is not only deeply intuitive, it also plays an important role in our mathematical descriptions of physical systems. For instance, we define an object’s speed as its displacement per a given time. But some researchers theorize that this Newtonian idea of time as an absolute quantity that flows on its own, along with the idea that time is the fourth dimension of spacetime, are incorrect. They propose to replace these concepts of time with a view that corresponds more accurately to the physical world: time as a measure of the numerical order of change.

Year On Earth breaks it down, explaining the complicated mechanics involved in trying to determine how long a year really is, why seasons and ice ages happen, and how not all years are created equal.
Tim Macmillan has been slicing time for more than twenty years now. His early attempts and the recent applications of his technique in nature documentaries, commercials, sports, music videos and his own short films can be watched on his vimeo page. His technique later mutated into the Bullet Time effect made popular by the Matrix movie. Watched enough? Then read an interesting article about him. Via Fleischfilm. [more inside]
Imagining the Tenth Dimension (Flash). 10th dimensional physics and string theory don't get any easier than this.
Olaf Stapledon was a man ahead of his time. His epic 'novel' Star Maker (1937) considered the emergence of genetic engineering, the outcome of the many worlds interpretation and delved deeper than any book before or since into the consequences of evolution on the cosmos. His fans have included the likes of Arthur C Clarke, Jorge Luis Borges and Virginia Woolf. Even his greatest detractor, C.S.Lewis, wrote an entire Cosmic Trilogy in response to his imaginings. Yet despite Stapledon's magnetic prose and extraordinary influence on speculative fiction his name remains largely forgotten by the world. Yet his words still resonate with insight: "Did not our life issue daily as more or less firm threads of active living, and mesh itself into the growing web, the intricate, ever-proliferating pattern of mankind?"
