This time-integrated photograph shows the high-powered laser shot at the diamond target (center), which is surrounded by several instruments. The bright white light is plasma. At just over 1 million atmospheres of pressure the diamond failed. Credit: Eugene Kowaluk/LLEFrom Live Science:
We've all heard that diamonds can cut through glass, but now scientists have found Earth's hardest solid can withstand pressures just over a million atmospheres before getting crushed.

And the human body can withstand about 27 atmospheres, if it's applied gradually, according to the U.S. Department of Energy.
