Asteroid 33 Polyhymnia May Contain Elements Outside The Periodic Table about study Superheavy elements and ultradense matter
The asteroid is so dense, physicists say it could contain elements not yet seen on Earth. elements in the other theoretical island of nuclear stability near Z = 164, which we predict to populate mass density values between 36.0 and 68.4 g/cm3
One of many options is so-called hydrino, i.e. ultradense subquantum form of hydrogen, which is also speculated to form a substantial portion of dark matter.
