The Unruh Effect

Worried about black holes? Consider this: Every time you accelerate - you generate an event horizon behind you. The more you accelerate away from it the closer it gets. Don’t worry, it can never catch up to you, but the Unruh radiation it generates sure can.

Using Stars to See Gravitational Waves

Now that gravitational waves are definitely a thing, it’s time to think about some of the crazy things we can figure out with them. In some cases we’re going to need a gravitational wave observatory - in fact, we've already built one.

The Backbone of Night

Carl Sagan teaches students in a classroom in his childhood home in Brooklyn, New York, which leads into a history of the different mythologies about stars and the gradual revelation of their true nature. In ancient Greece, some philosophers (Aristarchus of Samos, Thales of Miletus, Anaximander, Theodorus of Samos, Empedocles, Democritus) freely pursue scientific knowledge, while others (Plato, Aristotle, and the Pythagoreans) advocate slavery and epistemic secrecy.

Journey Through Space

Brilliantly narrated by film and television legend Sir Patrick Stewart, Journey To Space gives a sweeping overview of humanity’s accomplishments in space, as well as our ongoing activities and future plans. Journey To Space puts into historical context the magnificent contributions made by the Space Shuttle program and its intrepid space pioneers. It uses the most spectacular space footage – including unique views of Earth and operations in space – such as deploying and repairing the Hubble Space Telescope. It then goes on to show how the shuttle launched and assembled the International Space Station (ISS). Together, these programs have taught us how to live, build and conduct scientific experiments in space. The ISS will continue operating in space until 2024, and the film shows how it is building a foundation for the next giant leaps into space, concluding with a fascinating, realistic scenario of how astronauts will actually get to Mars, live there for long durations, and then return home after a two-and-a-half-year mission.
