TED-Ed: Could we harness the power of a black hole? | Fabio Pacucci
Imagine a distant future when humans reach beyond Earth, forge cities on planets thousands of light-years away, and maintain a galactic web of trade and transport. What would it take to make that leap? And where would we get enough...

The "myth" of the boiling frog | TED-Ed
Since 1850, global average temperatures have risen by 1 degree Celsius. That may not sound like a lot, but it is. Why? 1 degree is an average. Many places have already gotten much warmer and if average temperatures increase one more...

How To Make MUONS
This video is about how to create muons in a particle accelerator via bombardment of heavy nuclei with protons, which results in creation of charged pions (plus and minus). The pions then decay into muons and mu neutrinos, and the muons...

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...
