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...

Has a fifth fundamental force been discovered and how will this effect our understanding of the universe?

We live in an unusual age - the age when the stars still shine. We should count ourselves lucky - nearly all of future history will be dark. But events will still unfold in that long, cooling darkness, and civilizations may endure. So...

Inspired by Gene Roddenberry's Star Trek, physicist Miguel Alcubierre set out to transform one of the cornerstones of science fiction iconography, the Warp Drive, into reality. But is it even possible? Can we "warp" the fabric of reality...

Since the days of Ancient Greece, philosophers and scientists have been wondering: What is space? Is the absence of things.... a thing? These questions continued to fascinate physicists in the modern era, leading Isaac Newton, Ernst...

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...

On this Space Time Journal Club we look at how gravitational waves can be used to search for extra dimensions of space!

Unlock the secrets of Feynman Diagrams. Part 5 in our Quantum Field Theory series.

The Drake Equation tells us the likelihood that there are other advanced technological civilizations waiting for us among the stars. In this episode of Space Time we challenge you to use the Drake Equation to help us determine how near...

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...

The silence of the galaxy and the resulting Fermi Paradox has perplexed us for nearly 50 years. But our most recent surveys of the Milky Way finally allow us to draw scientific conclusions about the depressingly persistent absence of...

You've discovered a habitable exoplanet, but so has an an evil interplanetary mining corporation. Can you get to the planet before they strip it bare and leave it unsuitable for life? You're going to need a ship, the Lorentz...

Let's look further into what we don't yet know about the Big Bang, and how the theory could progress in the future. Since there is a discrepancy between general relativity and quantum mechanics, we continue to search for a grand unifying...

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.

Physics seems to be telling us that it's possible to simulate the entire universe on a computer smaller than the universe

Did you know Einstein never thought we’d find actual black holes in space? It took decades of research to show black holes are physically possible, and some of the scientists behind that research were honored this year with the Nobel...

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

For the past 90 years, the predictions laid out Einstein's general theory of relativity have continued to be confirmed by experimental science. The last hold out is gravitational waves - the idea that certain gravitational events cause...

This video is chapter 5 in my series on special relativity, and it covers how things that are moving (that is, moving relative to an inertial reference frame) at different speeds appear to be shorter in length... and longer in...

Over 100 years after Einstein proposed his theory of general relativity, we are proud to announce that his final major prediction has been verified! Gravitational waves have officially been detected by LIGO! This is a huge deal and an...

At the center of a galaxy more than 55 million light-years away, there's a supermassive black hole with the mass of several billion suns. And now, for the first time ever, we can see it. Astrophysicist Sheperd Doeleman, head of the Event...

If wormholes aren't just convenient plot devices for science fiction writers, they're still much weirder than anything we could make up.

The speed of light is often cited as the fastest anything can travel in our universe. While this might be true, the speed of light is the EFFECT and not the CAUSE of this phenomenon. So what's the cause? On this week's episode of Space...
