ShowingImportancePrizesTopicPlanck scale
The energy and length regime (~10^19 GeV, ~10^-35 m) at which quantum-gravitational effects are expected to become significant. Claims about the validity of established theories at, up to, or beyond this scale, and about Planck-scale phenomenology, belong here; everyday particle physics below it does not.
A microscopic black hole on the order of the Planck length cannot accrete ordinary matter at a meaningful rate.

The predicted Hawking spectrum is insensitive to modifications of trans-Planckian dispersion relations.

Modified trans-Planckian dispersion relations in black-hole models preserve the thermal spectrum at the Hawking temperature.

The Hawking spectrum can be derived assuming the quantum state is regular only down to an invariant Planck-scale cutoff.

In large extra dimension models, the fundamental scale of gravity can be as low as about 1 TeV.

If a claim here is wrong, or missing evidence, open it: every claim page carries its own entry for challenges, evidence, and corrections. If the graph is missing a claim entirely, propose it below. A proposal is reviewed on its merits; accepted claims are matched against the graph and enter it with their reasoning on record.
