Does the world have a beginning? And does time itself have a beginning? Our aim: Answer these questions Use physical theories NB: There are other questions about time in cosmology: - End of time? - Cosmic time? - Cosmological explanation of arrow of time?
COSMOLOGY IS NOT COSMETOLOGY Cosmology: The science or theory of the universe as an ordered whole, and of the general laws which govern it Also, a particular account or system of the universe and its laws Cosmetology: The art and practice of beauty culture
proposed new perspective on braneworld cosmology and quantum gravity in a an 'end-of-the-world brane' moving in a charged black hole spacetime
with the notion of a global cosmic time may arise if a privileged set of world lines quantum black holes the light pulse is supposed to end its 'crossing'?10
