Towards a Resolution of the Cosmological Singularity in Non-local Higher Derivative Theories of Gravity
Tirthabir Biswas, Tomi Koivisto, Anupam Mazumdar
One of the greatest problems of standard cosmology is the Big Bang singularity. Previously it has been shown that non-local ghostfree higher-derivative modifications of Einstein gr…
