Unexplainable
Unexplainable takes listeners right up to the edge of what we know and then keeps on going. The team tackles scientific mysteries, unanswered questions, and everything we learn diving into the unknown. New episodes Mondays and Wednesdays. From Vox and the Vox Media Podcast Network.
Episodes
Talking with the dead
“If only I could talk with them again.” It’s a common refrain for anyone who is grieving someone they love. Now, we can access technology like deadbots, or AI replicas of a lost loved one, to simulate those conversations, but at what cost? Maybe we’ve always had the capacity — within our own voices — to deepen conversations with the people we’re missing, even after they’re gone.

What’s cooler than being cool?
The future of quantum computing depends on getting way colder than ice cold — down to some of the coldest temperatures in the universe. The quest to build these super refrigerators takes us to nuclear bomb stockpiles, the moon, and … Party City?

Dark matter and the end of answers
Five-sixths of all the matter in the universe is this invisible stuff called dark matter, and scientists barely understand what it is. So what happens if we can't answer arguably the biggest mystery in the universe? One physicist decided to quit because he started asking questions that went way beyond what he initially thought science was for.
Guest: Joseph Howlett, reporter at Scientific America
What happened before the big bang?
It's a question that seems impossible to grapple with, but scientists won't take no for an answer. In this collaboration with Scientific American, we take on the big bang and a whole bunch of seemingly impossible questions.

A breakthrough in synthetic life
Synthetic biologist Kate Adamala has been making major headlines as her lab creates cells that feed, divide, and grow — all from nonliving parts. It may sound like sci-fi, but Kate believes that these “not quite alive” cells are key to a renewable future.

A few hundred milliseconds are often all you need to recognize a song, but a lot of recent hits have moved away from intros. Our friends at Switched on Pop (along with the National's Aaron Dessner) break down how song intros can shape our perception and what we lose when they disappear.
