Plasma in our universe
In our universe, almost all (<99%) of the visible matter, including stars and interstellar medium are plasma. Most of the plasma is at low density and can be investigated easily. But the interior of stars, giant planets and also our earth are made of an exotic state of matter, ranging from solid state to dense hot plasma.
Interior of our sun
Hydrogen at pressures around 300 Mbar and temperatures of 14 million degrees cause atoms to fuse - the ultimate energy source of our galaxy. Can we harvest this source on earth?
We have discovered more than hundred planets in other stellar systems. But we don't know how the planets (e.g. Jupiter and Saturn) are built and where the magnetic field comes from.
What is the property of iron at pressures of Mbar and temperatures of thousands of degrees?

If you can measure it: its NOT WDM
If you can compute it: its NOT WDM
