Yeah, so most atomic clocks use an atom of cesium or rubidium, but in general, I think it's, like, easiest to explain this process with, like, the element hydrogen because it just has one proton at its center and one electron orbiting it. And like orbit is a bit of a simplification for now, but let's just say orbit. Electrons, they have these different orbits.

Each of them are associated with like a different energy. And if an atom absorbs energy, let's say through like a little chunk of light or a photon, the electron will change its orbit. It'll go to this higher energy state. It'll go to a higher orbit. And then when the electron eventually goes down, energy is released from that atom as another photon.

And it's more precise because it's using optical light instead of microwaves.

Oh, I don't know anything about strontium.

Okay, so like in this case, the atom will only get excited if the laser is on beat. It has that specific frequency.

So what will OASIC, the clock, look like once it's built?

Wow. OK, so gravity and quantum mechanics interacting is like the holy grail of physics. OK, so how far along are these new clocks?
