Understanding the apparatus
The OMEGA lasers and diamond anvil cells are vital when in creating this sample
These lasers produce 30 kilojoules of energy in one-billionth of a second, heating the sample up to thousands of degrees.
Opposing diamonds Diamond is the hardest material in the world, making it ideal for applying as much pressure as possible with little deformation and cracking.
The gasket is a thin piece of material surrounding the sample in between the diamonds, acting as a seal in order to avoid leakage.
The hydrogen sample is only in the order of micrograms, but it is enough for scientists to carefully observe and study as it shifts into a metallic state.
Metallic hydrogen is more reflective than molecular hydrogen, meaning the light that bounces back to the detectors holds the answers to this study.
