SUMMARY:How Fast is the Universe Expanding? - Dr. Matthew Bothwell\, Insti
 tute of Astronomy\, University of Cambridge

DESCRIPTION:Around a century ago\, Edwin Hubble made one of the most impor
 tant discoveries in astronomical history: the Universe is expanding. Ever 
 since Hubble\, understanding exactly how fast the Universe is expanding ha
 s been one of the most important tasks in cosmology. Today\, astronomers a
 re faced with two puzzles: why is the expansion of the Universe speeding u
 p? And why do different experiments disagree about how fast our Universe i
 s expanding?\n\nThis talk will discuss the expanding Universe\, dark energ
 y\, and the ongoing 'Hubble tension' (which many people are calling a 'cri
 sis' for cosmology!)
