This series will explore the journey of scientific discoveries. Very often, science is known only by its finished product. But the path is not revealed. Through these lectures, we attempt to unravel the processes of science, including the struggles and failures.

The Hunt for the Heftiest Things We Know

Abstract: Black holes are the heaviest things we know. The only evidence we have so far for black holes has come from the cosmos. State-of-the-art technologies enable us to investigate the consequences of the strongest gravitational fields known which are around black holes. These consequences enable us to study their environs even out to the far reaches of the universe.  Black holes may in fact  play a key role in the evolution of galaxies like our own Milky way. How do we know that black holes are real? How do we find them? Why are they important? I will touch upon these ideas in the story of their discovery.
