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 40th 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.
