Scientists have simulated an elusive, superstrong form of carbon that may be tougher than diamonds, the hardest known material. But observing the real thing might require a trip far outside our solar system, to the center of an exoplanet — a feat that's not likely anytime soon, or possibly ever.
The research also helps to reveal what might be at the hearts of carbon-rich exoplanets, which are predicted to have just the right conditions for the formation of BC8."he extreme conditions prevailing within these carbon-rich exoplanets may give rise to structural forms of carbon such as diamond and BC8," study senior author Ivan Oleynik, a physics professor at the University of South Florida, said in a statement.
They found that BC8 is likely very stable at very high pressures of 1,250 gigapascals and above. That's well over 12 million times the pressure of the atmosphere on Earth's surface. Theory also suggests, however, that the crystal, once formed, would remain stable at ambient temperatures.
