Fundamental physics started the 20th century with the twin
revolutions of relativity and quantum mechanics, and much of the
second half of the century was devoted to the construction of a
theoretical structure unifying these radical ideas. Yet storm clouds
are gathering, which point towards a new set of revolutions on the
horizon in the 21st century. Space-time is doomed—how can it emerge
from more primitive building blocks? And how is our macroscopic
universe compatible with violent microscopic quantum fluctuations that
seem to make its existence wildly implausible? In this talk I will
describe these deep mysteries and outline some of our strategies for
making progress on them. I will also discuss plans for a giant new
particle accelerator with energy seven times higher than the Large
Hadron Collider, that will be necessary to make major progress on at
least some of these questions in the coming decades
