We imagine ourselves as existing within time and space. Yet, we only ever experience the present moment. It is all we have. And within the present moment there is no direct experience of past or future. Nor is the present moment located anywhere, since it is everything for us. In short, there is no map reference for being or consciousness. No time zone or hour.
Should we therefore abandon the idea that experience takes place in time and space? Might consciousness operate in an entirely different sphere, outside of the world of space and time? Or is space and time the only reality, and our experience a snapshot through which we make sense of the world.
Renowned multiverse theoriest Laura Mersini-Houghton, legendary physicist, writer and broadcaster Paul Davies and philosopher of science Craig Callender lock horns over the arrows of time.
