Description
Infinite derivative gravity is a theory which extends on general relativity by modifying the Einstein-Hilbert action. Where the hope is that we are able to remove the pathologies found in the UV region of general relativity. In this talk I will present various linearised metrics in the theory of infinite derivative gravity and will show that we indeed are able to remove the singularities that are usually found in general relativity without having to introduce ghosts to the theory. I will also show that these new metrics reproduce general relativistic metric in the infrared region.
