The Largest Black Holes in the Universe (VERSION ONE)

We’ve never seen them directly, yet we know they are there, Lurking within dense star clusters, Or wandering the dust lanes of the galaxy, Where they prey on stars, Or swallow planets whole. Our Milky Way may harbor millions of these black holes, the ultra dense remnants of dead stars. But now, in the universe […]

5 Experiments that Could have Destroyed the World

Dark 5 präsentiert 5 Experimente, die die Welt zerstört hätten können 5. Die Kola-Bohrung In der arktischen Zone im Nord-Westen Russlands befindet sich das tiefste je in die Erde gebohrte Loch. Sowjetische Wissenschaftler begannen 1970 mit der Bohrung und erreichten schließlich eine Tiefe von 40,230 ft (12,262 m) im Jahre 1989. Die Sowjets wollten durch […]

Why the solar system can exist

Have you ever wondered how the earth stays in orbit around the sun? I mean, the pull of gravity is stronger the closer you are to the sun, so you’d think that if the earth got bumped slightly towards the sun (like, if you jumped, or something), then the sun would pull just a little […]

Solar Tsunami

The SOHO spacecraft has recorded the effect of all this rising energy. Its ultraviolet sensors show a wavy pattern of gas on the sun’s surface, along with the super-hot halo of gas called the corona. The white regions are places where the rising gas suddenly escapes. Immense loops of ionized gas, ten times the diameter […]

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 […]

Cosmic Journeys – Earth in 1000 Years

Ice in its varied forms covers as much as 16% of Earth’s surface, including 33% of land areas at the height of the northern winter. Glaciers, sea ice, permafrost, ice sheets and snow play an important role in Earth’s climate. They reflect energy back to space, shape ocean currents, and spawn weather patterns. But there […]

White Holes | Space Time

This episode is supported by LegalZoom. Lurking in the depths of the mathematics of Einstein’s general relativity is an object even stranger than the mysterious black hole. In fact, it’s the black hole’s mirror twin: the white hole. Some even think that these could be the origin of our universe. The astrophysical phenomenon of the […]

The Black Hole Bomb and Black Hole Civilizations

Black holes are the largest collections of pure violent energy in the universe. If you come too close, they’ll devour you and add your energy to their collection. And so, the energy is lost to us forever. Or is it? It turns out there’s a universe cheat code. A way of powering civilizations until the […]

Wormholes Explained – Breaking Spacetime

If you saw a wormhole in reality, it would appear round, spherical, a bit like a black hole. Light from the other side passes through and gives you a window to a faraway place. Once crossed, the other side comes fully into view with your old home now receding into that shimmering spherical window. But […]
