S2016 E2 • Spaceships pushed by LIGHT – the future of space travel?

What if you could power a ship using sunlight instead of wind? Well in space, you can! Solar sails or light sails are pushed with light from the sun. Photons provide a kick when they reflect off the sail pushing the sail like an air molecule in the wind pushes a sailboat. Find out how a solar sail works and about the future of this technology!

S2016 E3 • The black hole death problem

Black holes are not as black as we once thought. They are theorized to die a slow death by evaporation, emitting energy known as Hawking radiation. But the mechanism for evaporation is not well understood. Then again, no one has ever even directly detected a black hole.

S2016 E4 • 5 weird ways to put out a candle

What happens when you pour liquid nitrogen on a flame? What about when you blow on the flame with a cup in the way? Try these five unusual ways to extinguish a candle. Pour out the flame with CO2. Cut off the oxygen supply to the flame without fully covering it. Snuff out the flame with a coil of copper wire, and when it appears dead, it will amazingly come back to life!

S2016 E5 • Gravitational Waves Discovered for the First Time!

On Feb 11, 2016 Scientists at LIGO announced that they had detected gravitational waves for the first time. In the press conference heard round the world, they showed the tell-tale waveforms indicating that huge event in which two black holes merged 1.3 billion lightyears away, had created waves that passed by the LIGO detectors and were finally heard. Einstein predicted the existence of these waves in his 1915 theory of general relativity. But it took a long time for us to come up with the technology to detect them. For one, we had to invent lasers! This video discusses why this discovery is important, what it means for astronomy, and what’s next. If you can’t tell, I’m very excited.
