While the Big Bang model is well established in cosmology, it is likely to be refined in the future. Little is known about the earliest moments of the universe's history. The PenroseHawking singularity theorems require the existence of a singularity at the beginning of cosmic time. However, these theorems assume that general relativity is correct, but general relativity must break down before the universe reaches the Planck temperature, and a correct treatment of quantum gravity may avoid the singularity.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When does the Planck temperature show a singularity existed?
Ah, so.. unanswerable

Tibetan music often involves chanting in Tibetan or Sanskrit, as an integral part of the religion. These chants are complex, often recitations of sacred texts or in celebration of various festivals. Yang chanting, performed without metrical timing, is accompanied by resonant drums and low, sustained syllables. Other styles include those unique to the various schools of Tibetan Buddhism, such as the classical music of the popular Gelugpa school, and the romantic music of the Nyingmapa, Sakyapa and Kagyupa schools.
