Feature Guest: Gil Holder
Have you heard of the Great Attractor or the Great Wall? The universe evolved from a hot dense not quite perfectly uniform state to now contain galaxies in sheet-like structures separated by huge voids. These clusters and superclusters of galaxies make up the largest scale structure in the observable universe. How exactly did they emerge, what role does dark matter and dark energy play in the evolution of structure and just where is our universe headed? To help us answer those questions today we’re joined at The Star Spot by cosmologist Gil Holder.
Current in Space
With the building of the James Webb Space Telescope coming along quickly, Anuj explains how the successor to Hubble will open a new window on the universe? And following the recent 49th anniversary of the Apollo 1 disaster, Tony reflect on three major tragedies in the history of space exploration and reflects on why it’s still worth the risk. Finally Dave reports on the groundbreaking discovery of gravitational waves via one of the most powerful phenomena in the universe: binary black hole mergers.
