What is Holography and how does it help us Quantize gravity? In this conversation I speak with Pedro Vieira, one of the worlds leading experts on holographic dualities and their application in quantum gravity. We start our discussion with a few standard but big questions, like why is quantum gravity is difficult, what is quantum field theory, and what is gauge symmetry. We then dive into the topic of holography, which in broad and provocative terms is the idea that our universe and everything in it might be a hologram projected from some lower dimensional quantum theory. That is, there might be a duality between the mathematics that describes our world including gravity and the mathematics that describes a world with quantum mechanics and without gravity in one dimension lower. If such a duality were true, then it might provide a radial way of side stepping all of the usual difficulties of quantizing gravity.
