What is this thing we keep hearing about – the Higgs Boson, and why is it important? It’s been said that the best way to learn is to teach. And so, today I’m going to explain everything I can about the Higgs boson. And if I do this right, maybe, just maybe, I’ll understand it […]

When space tourism gets underway, companies will have many options for getting people to and from the Moon, some faster than others.

In science fiction, wormholes are a method often used to travel great distances across space. Are these magic bridges really possible? With all my enthusiasm for humanity’s future in space, there’s one glaring problem. We’re soft meat bags of mostly water, and those other stars are really really far away. Even with the most optimistic […]

When humans finally blast off for another world, where will we be going? Will we return to the Moon, and take over where the Apollo astronauts left off, or will we press onto Mars, and set foot on a whole new planet? Humanity is going to need to make a difficult choice in the next […]

What does it take to have the “Right Stuff” to become an Astronaut? Are you an overachiever? Are you working on multiple PhDs in obscure and difficult topics? Can you speak multiple languages, including alienese? Do you suspect, if handed the controls, you could complete the Kessel Run in fewer parsecs than Han Solo? If […]

If we could dig a tunnel through the Earth, what would happen? And is this even possible? Long distance air travel sucks. Anyone who’s ever had to sit on an airplane for 17 hours, enduring screaming babies, terrible internet, and the constant threat of deep vein thrombosis knows how bad it sucks. I know, I […]

Europa is probably the best place in the Solar System to go searching for life. But before they’re launched, any spacecraft we send will need to be squeaky clean so don’t contaminate the place with our filthy Earth bacteria. Look at what humans did to your planet. We filled your whales with plastic, and the […]

What was the signal received in 1977? Was it a cryptic message from an alien civilization? In 1977, radio astronomer Jerry Ehman was looking through observation data from the Big Ear Radio Telescope. He was searching for evidence that alien civilizations might be trying to communicate using radio waves as an alternative to metal probes. […]

Will the Big Bang expansion eventually come to a stop over the course of infinite time and ultimately pull everything back in again? Imagine the Big Bang in your mind. You’re picturing galaxies hurtling past in all directions, like so much star shrapnel from a celestial pinata. I stole this cool expanding toy from my […]

We know that in space, no one can hear you scream. But what would things sound like on another planet? When humans finally set foot on Mars, they’re going to be curious about everything around them. What’s under that rock? What does it feel like to jump in the lower Martian gravity. What does Martian […]

Europa’s water exists in a layer around the planet, encased in a layer of ice. Could there be life down there? Hooray! Welcome to the 200th official episode of the Guide To Space! First off, thank you. Thank you for watching, liking, sharing, subscribing and being a patron of our show. Yes, you. Thank you. […]

Would shooting a black hole into an antimatter black hole destroy them both? I’ve wondered out loud how it might be possible to destroy a black hole because I talk to myself and sometimes there’s a camera watching. I’ve suggested a bunch of crazy ideas, like blasting it with rockets, shooting lasers at it, smashing […]

For millennia, human beings have stared up at the night sky and stood in awe of the Milky Way. Today, stargazers and amateur astronomers continue in this tradition, knowing that what they are witnessing is in fact a collection of hundreds of millions of stars and dust clouds, not to mention billions of other worlds. […]

Dr. Mike Brown is a professor of planetary astronomy at Caltech. He’s best known as the man who killed Pluto, thanks to his team’s discovery of Eris and other Kuiper Belt Objects. We asked him to help us explain this unusual region of our solar system. Soon after Pluto was discovered by Clyde Tombaugh on […]

The Earth’s atmosphere is a total drag, especially if you’re trying to orbit our planet. So how low can you go? The Earth’s atmosphere is a total drag, especially if you’re trying to orbit our planet. It’s a drag. Get it? Atmospheric drag. Drag. Drag. Hi, my name is Fraser Cain. I’m the publisher of […]
