Title: Probing the Dark Universe
Abstract: Over the last two decades, cosmologists have made a remarkable discovery about our universe: only 4% is made of ordinary matter like atoms and molecules. The other 96% is dark, in forms unlike anything with which we are familiar. About 25% is dark matter, which holds galaxies and larger-scale structures together, and may be a new elementary particle. Another 70% is thought to be dark energy, an even more mysterious entity that appears to be driving the accelerated expansion of the universe. This talk will introduce the Dark Universe, give an overview of what we have learned about it, and describe new experiments and observatories that aim to illuminate these enigmas.
