"In that framework, gluons inside a nucleus partially overlap and obscure each other -- similar to layers of clouds blocking sunlight -- reducing the probability of certain particle production processes," he said.

After the war the problem of gravitational collapse was largely forgotten as most scientists became caught up in what happens on the scale of the atom and its nucleus.

Atomic nuclei are more than 10,000 times smaller than atoms.

The researchers connected their thorium excitation apparatus to a conventional optical atomic clock, demonstrating that the nuclei could serve as a highly precise timekeeping reference.

By using atomic nuclei as exceptionally stable references, nuclear clocks could eventually allow scientists to measure time and other physical quantities with levels of accuracy that existing technologies cannot reach.

This property is crucial because it allows researchers to control the energy state of a nucleus with a laser, something that is not possible in the same way for most other atomic nuclei.

Breaking up atomic nuclei, however, requires quite a lot of money and a generous supply of electricity.

"So far I have done nothing but nucleuses," said Olive, as they sat down.

She saw him start a dozen nucleuses of fires; saw them advance till they halted at the edge of the burned ground, beyond the wagon, so that it stood safe in a vast black island.

Hall, Price, and Kelsey headed in with straggling wagons to form the nucleuses of their columns; but the morning wore on and the Missourians, now under Woodhull, had not yet broken park.
