Latest measure of cosmic expansion hints that universe is growing faster than expected

by Lori Ann White

The universe is full of mysteries that merit an exclamation or two of wonder and delight. Black holes, supernova explosions, planets around other stars, the thought that most of the matter surrounding us is some kind of stuff that we can’t detect—these are just a few of the cosmic marvels that warrant a “Wow!” or a “Neat!” or a “Gee whiz!”

Or even a “Holy cow!”

One group of scientists has found a way to permanently remind themselves of this.

Where are they now? 
 -- An Interview with KIPAC alum Chihway Chang

In the series, "Where are they now?" we check in with KIPAC alumni: where they are now, how they've fared since their days exploring particle astrophysics and cosmology at the Institute, and how their KIPAC experiences have shaped their journeys.
