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.
When must quantum gravity break down?
A: unanswerable

Livy presents these as signs of widespread failure in Roman religio. The major prodigies included the spontaneous combustion of weapons, the apparent shrinking of the sun's disc, two moons in a daylit sky, a cosmic battle between sun and moon, a rain of red-hot stones, a bloody sweat on statues, and blood in fountains and on ears of corn: all were expiated by sacrifice of "greater victims". The minor prodigies were less warlike but equally unnatural; sheep become goats, a hen become a cock (and vice versa) these were expiated with "lesser victims". The discovery of an androgynous four-year-old child was expiated by its drowning and the holy procession of 27 virgins to the temple of Juno Regina, singing a hymn to avert disaster: a lightning strike during the hymn rehearsals required further expiation. Religious restitution is proved only by Rome's victory.
What is the only proof of religious success over prodigies?
A: Rome's victory

Standing at 117 metres (384 feet) in height and 360 metres (1,180 feet) in width, the Potala Palace is the most important example of Tibetan architecture. Formerly the residence of the Dalai Lama, it contains over one thousand rooms within thirteen stories, and houses portraits of the past Dalai Lamas and statues of the Buddha. It is divided between the outer White Palace, which serves as the administrative quarters, and the inner Red Quarters, which houses the assembly hall of the Lamas, chapels, 10,000 shrines, and a vast library of Buddhist scriptures. The Potala Palace is a World Heritage Site, as is Norbulingka, the former summer residence of the Dalai Lama.
What is Norbulingka?
A:
former summer residence of the Dalai Lama
