Could We Decode Alien Physics?
How hard can it really be to decode alien physics and engineering? It’s gotta map to our own physics - I mean, we live in the same universe. We start by noticing that the alien technology seems to use good ol’ fashioned electronics, even...

Are Dark Matter And Dark Energy The Same?
Astronomers are the worst at naming things. Dark energy AND dark matter? Who can remember which is which. But perhaps one astronomer has just fixed it, with a theory that says perhaps actually they are they same stuff.

Could the Universe End by Tearing Apart Every Atom?
The universe is expanding, and that expansion is accelerating. We don’t know what’s causing that acceleration, but that hasn’t stopped us from giving it a name. We call this unknown influence dark energy. The observed acceleration is,...

Could a Shirt Hear Your Heartbeat? | SciShow News
Microphones keep getting smaller and smaller, but have you ever asked what it would be like to have a bigger one in the form of a shirt? And though we tend to incorrectly think that we’re having two-way conversations with our pets, we...

Could Your Blood Type Ever Change?
From A positive to O negative, everyone's born with a blood type, and they're stuck with that blood type for their whole lives... or are they?

What Happens When a Venomous Snake Bites Itself?
Venomous snakes produce some of the world’s deadliest substances, so they have to be pretty careful about how they use it. But what happens if they accidentally inject themselves with their own harmful cocktail?

Anti-gravity and the True Nature of Dark Energy
We've come a long way in our understanding of dark energy. In previous episodes we've looked at how our universe is paradoxically flat and how dark energy is exponentially accelerating the expansion of the universe. Now, let's dive into...
