Journey to the center of the Earth
First of its kind experiment uses diamond anvils to simulate the Earth's core
Flat Earth NOT. Here is more scientific work to simulate the conditions of the Earth core in a laboratory. This supports what is already known about how energy waves (earthquake) travel across different boundary layers of inner material/temperatures.

Excerpt:
"Seismic apparatus which measure how earthquakes travel through the planet are pivotal to map some of the larger structural arrangements within the Earth, and thanks to this it has long been known that at the heart of the Earth lies a solid core surrounded by a less dense liquid outer core. For the first time, experiments and simulations have shown researchers details about this outer core which were previously unobtainable. And these experiments include some fascinating details.
"Recreating conditions found at the center of the Earth up here on the surface is not easy," remarked Project Assistant Professor Yasuhiro Kuwayama from the Department of Earth and Planetary Science. "We used a diamond anvil to compress a sample of liquid iron subject to intense heat. But more than just creating the conditions, we needed to maintain them long enough to take our measurements. This was the real challenge."

Precise measurement of liquid iron density under extreme conditions. A big step forward in estimating the composition of the Earth's core, by sciencedaily.com

Summary:
Scientists have measured the density of liquid iron -- the main component of rocky planet cores -- under conditions similar to Earth's liquid core: 1,000,000 atmospheres and 4,000 degrees Celsius. Accurate density measurements of liquid iron under such extreme conditions are very important for understanding the chemical make-up of our planet's core.
