Something weird happens when you keep squeezing

Something weird happens when you keep squeezing

Under extreme pressures, matter defies the rules of physics as we know it.

Physicists have a pretty good handle on how stuff behaves on the surface of the Earth. But a lot of matter in the universe exists outside this narrow band of relatively low temperatures and pressures. Inside planets and stars, the crushing force of gravity begins to overwhelm the electromagnetic and nuclear forces that keep atoms apart and maintain the shapes of molecules.

What happens next? Scientists (including a consortia of researchers at the NSF’s Center for Matter at Atomic Pressures​​) are just starting to figure that out. They use a variety of tools (including some humongous lasers) to simulate planetary cores and see what happens. A few standout findings so far:

Water can become a hot black ice that conducts electricity:

Hydrogen gas can be compressed down into a shiny metal:

Sodium (a soft, silvery metal at atmospheric pressure) can turn transparent:

What happens under extreme pressures deep with planets also influences their ability to foster life. Check out our videos about the search for Earth-like worlds beyond our solar system:

Here’s a closer look at another giant laser (at the National Ignition Facility):

    This was absurdly well produced. Makes me feel like I’m a kid watching a science show on TV again.

  2. iPeaceful says:

    loved the animation style and sound design. thank you for doing such a great job communicating science!

  3. xKINGx says:

    I love how Vox made this highly technical topic interesting to the average people like me. More of this please! 😊

  4. Nu'man Nor Shahrin says:

    Vox turning a new leaf and making science videos now. Love the video btw.

  5. Alexander S says:

    I really appreciate you traveling all the way to the center of the sun for this video; really demonstrates your dedication to your work

    • Moonshot says:

      bro he didn’t actually travelled inside the sun bro it’s just an animation the real guy is actually just in a green screen bro and he-

    • Caio Macedo says:

      @Moonshot If he is in a green screen, why was we wearing SUNglasses? Touché!

    • Noah Miller says:

      @Moonshot if you look closely, the sun is all around him, so he must have travelled through the sun. What do you think spacex has been doing lately? thats how he got there

    • unloco says:

      Bonus points for diving into it during the day. That’s honest work!
