omega| Last letter of the Greek alphabet. 1) Ω (upper-case omega) is used in astronomy as a symbol for the mass density of the universe, expressed as a fraction of the critical density of about 10−26oetry kg/m3. If Ω is 1.0 or less, the universe will expand forever; if it is more than 1.0 the gravitational pull of its mass will be strong enough to reverse its expansion and cause its eventual collapse. The value of Ω today is estimated to be close to 1; this implies that an instant after the Big Bang, it must have been almost exactly 1, to an extraordinarily high degree of precision. This cosmic ‘fine tuning’ may have been due to cosmic inflation. 2) In physics ω (lower-case omega) stands for angular frequency. |

| The outlying villages, they say, are by them called {kappa omega mu alpha iota}, by the Athenians {delta eta mu iota}: and they assume that Comedians were so named not from {kappa omega mu 'alpha zeta epsilon iota nu}, 'to revel,' but because they wandered from village to village (kappa alpha tau alpha / kappa omega mu alpha sigma), being excluded contemptuously from the city. And if it be my Alpha and Omega that everything heavy shall become light, every body a dancer, and every spirit a bird: and verily, that is my Alpha and OmegaTwo abysmal beasts sprang at each other's throats that day beneath the shadow of earth's oldest cliffs--the man of now and the man-thing of the earliest, forgotten then, imbued by the same deathless passion that has come down unchanged through all the epochs, periods and eras of time from the beginning, and which shall continue to the incalculable end--woman, the imperishable Alpha and Omega of life. |
