Hawking Radiation
As the name implies, Hawking Radiation is one of the discoveries we most associate with Stephen Hawking. It’s a concept that popped up relatively early in his career, and scientists have continued to study it all these years later.
Environmental Advocacy
One of the biggest risks to the wellbeing of humanity is climate change, and Hawking was a strong advocate for drastic alterations to industrial society to counteract the warming trend.
Early in his adult life, Hawking was infamously diagnosed with a rare form of amyotrophic lateral sclerosis (ALS). While the deterioration of his motor control was slower than most other cases, and his lifespan was surprisingly long, his body eventually became almost entirely inoperable.
Singularities
Another important aspect of Hawking’s legacy is his attempts to understand the implications of the extremely dense center of black holes. Inside one, it’s theorized that we can find a gravitational singularity – a point of infinite density.
