If you've seen photos or videos of the Large Hadron Collider, you know it's massive. It is, after all, the largest machine humans have ever built.
Now BBC News has made a 360-degree video that allows you to feel like you're inside this machine that's unravelling the secrets of the universe.
The LHC is where scientists discovered the Higgs boson in 2012, a particle that gives every other particle mass.
And they're not done yet. Last year, they doubled the energy at which the LHC smashes protons together. This year, they may be on the verge of new physics.
When two protons collide at nearly the speed of light, they explode into a cascade of many other particles. Doing this at higher energies allows them to find even more particles in the collision.
You can step inside where it all happens, with a jaunty British man narrating your journey.
If you wonder why the video doesn't move for the first minute or so (I did), it's because it's one of YouTube's new 360-degree videos, so you have to do the moving. This is why it only works properly in Chrome on a computer or in the YouTube app on your phone.
Enjoy the ride:
After you're done, hop over to the BBC to see how producers made the film.
