infinity

Meanings

1. 1

   Some of the most beautiful and thus appealing physical theories, including quantum electrodynamics and quantum gravity, have been dogged for decades by infinities that erupt when theorists try to prod their calculations into new domains. Getting rid of these nagging infinities has probably occupied far more effort than was spent in originating the theories.

3. 3
   noun

   time without end

4. 4
   noun

   An idealised point which is said to be approached by sequences of values whose magnitudes increase without bound.

From Middle English infinite, from Old French infinité, from Latin īnfīnitās (“unlimitedness”), from negative prefix in- (“not”), + fīnis (“end”), + noun of state suffix -tās.
