    Fighting quantum weirdness with quantum weirdness. Quantum cryptography may be our only defence against the encryption-cracking threat of quantum computers

    Second interstellar rock possibly discovered by Amir Siraj and Avi Loeb in 's CNEOS catalog of past meteors. It vaporized in our atmosphere in 2014, but came in fast enough that it may have come from beyond the solar system. 'Oumuamua has friends!

    Join us this week for practical DIY instructions on how to enclose an infinite universe into a finite boundary. A conformally compactified hyperbolic cosmos makes great wall art or a special gift for someone who already has everything!

    The most spectacular possible end of the universe has got to be The Big Rip. Happily there's only a *little* bit of evidence that it could happen.

    "Why, sometimes I've believed as many as 6 impossible things before breakfast." I feel just like the Queen of <3s - the 6 winners of our perpetual motion challenge are the most believable impossible things ever Full winning entries on Insta

    The measure of all matter and energy in the universe is inscribed in the fiery speckles of the cosmic microwave background. It's crazy that we've learned how to read this secret language. You can too.

    Galaxies also fall into constellations - rings on the sky that are echoes of the first sound waves to reverberate through the universe

    What does the near future of human space travel look like? shared some surprising insights with me at his beautiful island home. Soon on ! Thanks for the warm welcome, Richard

    Reflect our universe in the mirror, flip it to antimatter, OR reverse the direction of time and you break physics. But do all three and you get back to where you started. CPT symmetry is weird.

    With the bizarreness of string dualities, is it possible for string theory to be at the same time both right and wrong? Our followup to Why String Theory is Right explores the other option.

    Slight delay on today's release - it'll be out tomorrow! In the meantime, here's a graphics mockup I (Matt) put together for next week's episode, in which we show that the looking-glass universe is as strange as the stories tell us.

    Outer space is simple compared to the messy inner spaces of our social media universe. 's new series makes me think we should leave FB at home when we settle Mars

    Apologies for those waiting for our Wednesday release! Due to the holiday last week (and being with our families and stuff) we're taking a release break this week. We'll try to be twice as mindblowing next week to make up for it.

    Has the ANITA neutrino detector done what the LHC couldn't? Perhaps the most exciting evidence for a beyond-standard-model particle in a long time

    Why has a generation of geniuses been so obsessed with string theory? Even if it ultimately proves wrong (or not even), there are bits that look awfully right.

    In case you didn't get your fill of phantoms and imaginary beasts on Halloween, try our episode on virtual particles. How real are they?

    Does Schrodinger's cat chase quantum strings? We avoid this and other silly questions in our very VERY serious episode on string theory. Which is a very serious theory.

    You know how the 2-D residents of flatland couldn't see into the 3rd dimension? That's because the didn't build gravitational wave detectors. Check out this week's episode to see how we hunt for higher-D space!
