NASA’s New Space Engine Is Powered by Nuclear Fission

From a technology standpoint, there’s not too many greater challenges than nuclear power in space. The physics involved in it is quite intense — it has that luster of something totally different. We start with that highly enriched core, the splitting of the atoms generates that heat that we need at the right power levels, […]

How Einstein’s Eclipse Changed the Course of Physics Forever

About every 18 months, the Moon passes directly between the Sun and the Earth for a total solar eclipse. This alignment casts a brief shadow on Earth that we can track … and its location changes each time. This year’s eclipse swept across South America, stretching over Chile and Argentina. It was visible over the […]

When 2000°F Solar Power Hits a Block of Dry Ice

Everyone knows dry ice is super cold, and our Mega Solar Scorcher is super hot. So what happens if they go up against each other in a battle? [Captions by Judy V. at Y Translator] [Music] [Music] Guys, we’ve had literally hundreds, possibly thousands of comments asking to see what happens if we pit dry […]

How Earth’s Magnetic Field Twists and Buckles During Solar Storms

Traveling at the near speed of light, energetic particles shooting out from the sun can zip through space, smack into our planet’s atmosphere, and cause incredible disruptions. And one of the biggest impacts we know of happened during the tail end of the Vietnam War. President Nixon really wanted to pull us out, but wanted to […]

Mini-Nuclear Reactors Are Coming, and They Could Reinvent the Energy Industry

Pat, we have a reactor trip on Unit 5. Containment is isolated. Demon water is isolated. CVCS is isolated. DHR is in service. And pressurizer heater trips has occurred. All safety functions are green. Understand. We’ve got a reactor trip on Unit 5 and all safety functions are green. That’s correct. Ryan, can you take […]
