“Quantum Gravity: Is it Physics?”
Quantum gravity is purported to be the theory which underlies both quantum theory and general relativity. I will introduce the subject, emphasizing recent results of one approach to the problem which suggest that spatial geometry is discrete. Such discrete geometry may have an observational signature. I will describe limits on discrete geometry by astrophysical observations and will also argue that, in the not too distant future, quantum gravity may become physics and enjoy contact with observation and even experiment.
