• n moment magnitude scale a logarithmic scale of 1 to 10 (a successor to the Richter scale) that enables seismologists to compare the energy released by different earthquakes on the basis of the area of the geological fault that ruptured in the quake

## Usage

### In science:

Detailed observations by a dedicated satellite mission (CMBPol) therefore provide information about energy scales as high as 1015 GeV, twelve orders of magnitude greater than the highest energies accessible to particle accelerators, and probe the earliest moments in the history of the universe.

Unlike hadronic probes, that spectrum is sensitive to the earliest moments in the evolution, when the energy densities are an order of magnitude above the QCD conﬁnement scale (1 GeV/fm3).
