It's not too often that a giant of physics threatens to overturn an idea held to be self-evident by generations of physicists. Well, that may be the fate of the famous Penrose Singularity Theorem if we're to believe a recent paper by Roy...

Science, Religion, and the Big Bang

How will AI improve our lives in the years to come? From its inception six decades ago to its recent exponential growth, futurist Ray Kurzweil highlights AI's transformative impact on various fields and explains his prediction for the...

The Nobel prize in physics this year went to black holes. Generally speaking. Specifically, it was shared by the astronomers who revealed to us the Milky Way’s central black hole and by Roger Penrose, who proved that in general...

Normal maps are useless inside black holes. At the event horizon - the ultimate point of no return as you approach a black hole - time and space themselves change their character. We need new coordinate systems to trace paths into the...

What is inside a black hole? Inevitable crushing doom? Gateways to other universes? Weird, multidimensional libraries? If you’ve ever wanted to know then you might be in luck - Some physicists have argued that you’re inside one right now.

Black hole singularities break physics - fortunately, the universe seems to conspire to protect itself from their causality-destroying madness. At least, so says the cosmic censorship hypothesis. Only problem is many physicists think it...

Isaac Newton's Universal Law of Gravitation tells us that there is a singularity to be found within a black hole, but scientists and mathematicians have found a number of issues with Newton's equations. They don't always accurately...

Quasars, X-ray Binaries and Supermassive voids at the center of our galaxies .... black holes take many forms. In this episode Matt tells us what these different types of black holes are and how scientists are using VLBI, Very Long...

Black holes! From Stephen Hawking to Interstellar, black holes are mammoths in the world of science AND sci-fi. But what exactly IS a black hole? Do events happen inside black holes? Are black holes really a hole? Are black holes really...

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...

Science, Religion, and the Big Bang

In the last episode Matt discussed how the Penrose Diagram enabled you to map how black holes affect Space Time. In this episode you can use that knowledge to stop an all-too-real threat to our planet. Aliens are trying to destroy the...

Find out how time and space switch roles when we move beyond the event horizon of the black hole.

Hank gives us an inclusive overview of how everything in the universe is thought to have begun, and how cosmologists predict it will all come to an end. Now get happy!

Reid Reimers expands your mind with an explanation of white holes -- celestial objects that almost definitely are not real things that can be found in nature. Except, we might have actually seen one.

What really happens when you approach the event horizon of a black hole?

Mathematician Kelsey Houston-Edwards explains exactly what singularities are and how they exist right under our noses.

A naked singularity is something that should be a black hole, but it’s neither black nor a hole. If they exist, they’ll rewrite physics as we know it.

Most politicians choose their words carefully, to shape the reality they hope to create. But does it work? Etymologist Mark Forsyth shares a few entertaining word-origin stories from British and American history (for instance, did you...

Here on the internet, we love us some memes. But where do they come from? Yes we know, they are user generated. But to an internet layman, they seem to just appear, in HUGE quantities, ready for cultural consumption. Are they a sign of a...

In our SERIES FINALE of Crash Course Computer Science we take a look towards the future! In the past 70 years electronic computing has fundamentally changed how we live our lives, and we believe it’s just getting started. From ubiquitous...

Where is the center of the universe? All this, everything you see around you, started in a big bang, from a point smaller than the point at the end of this sentence. It as an infinitesimally small point, called a singularity....

What came before the Big Bang? what happened before the big bang? Since time is thought to have started at the big bang, asking what happened "before" is like asking what is North of the North pole? It may have no...
