Decayed [adjective]

The best way to estimate the age of a planet’s surface is to analyze its rocks, using the radioactive decay of its elements as a geologic clock.

The researchers hoped to use it to simulate false vacuum decay and bubble collisions.

Planets heated their original rocks with the decay of radioactive elements, collisions with asteroids or other planets, and with the leftover heat of their own formation.

A limited quantum computer, it specializes in solving optimization problems by letting qubits seek out the lowest-energy configuration available — a process not unlike false vacuum decay.

Because for every hydrocarbon atom that goes into the Earth, an oxygen atom is not used up in the decay process.

Radioactive decay of elements in the Earth added a lot of heat into the mix, prolonging the cooling time.

Vacuum decay is the idea that the universe that we are living in is not fully stable.

That deep, the decay of calcium can create air pockets with 33 to 88 percent hydrogen by volume.

It was a decayed house of superb proportions, but of a fashion long passed away.

Some half-decayed pieces of cloth and portions of wearing apparel were still lying in it.
