" E = mc^2, High energy and intensity opens windows on the world"
The profound discovery of Einstein a century ago, that particles can both be
made from energy and disappear back into energy, inspires the experiments
that provide our knowledge of the smallest building blocks of matter. The
experiments, done at enormous energy and intensity frontier accelerators,
have led to a consistent theory of the origins of our world up to a certain
point. However, at an energy scale not far above what we can attain at
existing accelerators, this picture is predicted to break down. Moreover,
the theory of the very small is intimately connected to cosmology -- the
ultimate cause and structure of our universe. Cosmological observations
again point to the need for a new theory in this energy range. In this
colloquium, I will trace out the path from where we are and what we need to
do to take the next step towards understanding the nature of space and time.
The discovery of new particles or new laws at energy and intensity frontier
accelerators will open up windows on this world.
