Stephen Hawking has died at the age of 76.
The famed theoretical cosmologist garnered international celebrity for his works of popular science, like A Brief History in Time.
But Hawking grew to a greater stature as an academic researching black holes and their gravitational points of no-return.
Hawking spent his entire academic career at the University of Cambridge, where he studied large cosmological structures, including stars, and the intense gravitational fields that remain after their collapse.
The term Hawking Radiation bares his name due to his theoretical research into quantum mechanics and event horizons.
Hawking theorized that quirks of quantum mechanics caused black holes to emit particles, which is know called black hole evaporation.
