An Accelerating Universe and Event Horizon

Recent data from type Ia supernovae show that our universe is currently expanding with an accelerating rate. This acceleration may continue forever or may change. In this talk I will discuss some implications of an accelerating universe. If the acceleration is forever it presents a strong challenge for string theories. I will also discuss how structure formation is affected.

A Departure from Prediction: Measurement of Electroweak Parameters at NuTeV

The NuTeV collaboration has extracted the electroweak parameter, sin2thw, from the measurement of the ratios of neutral current to charged current neutrino and antineutrino cross sections. We find that our measurement, while in agreement with previous neutrino electroweak measurements, is not consistent with predictions. To facilitate interpretation of this result, model independent analyses are also presented.
