This specialized material, formed into the Quintet's speaker cabinets with non-parallel walls to diminish internal standing waves, is truly the next generation in compact home speaker technology.

Then as the planets formed, they cleared out the material in their vicinity.

It could be defects due to missing atoms, thermal vibrations of the crystal lattice, or even the boundaries between small, imperfectly formed crystals that make up the material.

According to a new computer model, liquid methane in contact with a partially hydrogen-terminated diamond surface at extremely high pressures and temperatures spontaneously forms longer hydrocarbons, and hence the material of crude oil could be formed deep in the earth.

Scientists are eager to examine the asteroids because they formed in the same primordial cloud of gas and stellar material that collapsed to make the sun and the planets about 4.5 billion years ago.

The material was then injected into a mold and the desired shape formed.

And the microfossils in the sediment over the crater are either misinterpretations of material that has recrystallised over time, or were washed in from nearby rocks just after the crater was formed.
