Stephen Hawking: Cosmology’s Brilliant Mind Who Changed How We Understand The Universe
His work on black holes and cosmic origins keeps challenging and expanding knowledge.
Stephen Hawking: A Life That Transformed Science
Stephen Hawking, one of the most celebrated scientific minds of the modern era, profoundly altered our understanding of the universe. Despite battling the debilitating effects of amyotrophic lateral sclerosis (ALS), his ground-breaking ideas about black holes, the Big Bang, and cosmology left an indelible mark on physics while his books inspired millions(4)(2)(3).
The Early Life of Stephen Hawking
Stephen William Hawking was born in Oxford, England, on January 8, 1942, coincidentally exactly 300 years after Galileo Galilei’s death(1). His parents were both academically inclined; Stephen’s father wanted him to pursue medicine, but Stephen was fascinated by mathematics and physics. He attended University College, Oxford, where he read physics before moving on to the cosmology research program at Cambridge(1).
- Birthdate: January 8, 1942, Oxford, England
- University Education: Studied physics at Oxford; took up cosmology at Cambridge
- Early ambition: Initially wanted to study mathematics, but Oxford did not offer it as a major
Confronting ALS: A Remarkable Perseverance
In early 1963, just before his 21st birthday, Hawking was diagnosed with motor neuron disease, more commonly known as Lou Gehrig’s disease or ALS(1)(5). Doctors predicted he would not live more than two years, yet he continued his studies and research, eventually earning his doctorate from Cambridge in 1966(5).
- ALS Diagnosis: Discovered shortly before turning 21
- Doctors’ prognosis: Less than two years to live
- Defied odds: Lived more than 50 years post-diagnosis, continuing his academic work until his death at 76(4)(5)
Though ALS forced him to rely on a wheelchair and advanced communication technology, Hawking’s tenacity and wit endured, endearing him to colleagues and the public alike(5).
Scientific Journey: From Singularities to the Big Bang
Hawking’s early research focused on singularities—points in space-time where physical quantities become infinite, such as inside black holes. Building on mathematician Roger Penrose’s work, Hawking demonstrated that the universe itself most likely originated from a singularity, lending strong theoretical support to the Big Bang notion(2)(5)(4).
- Singularity Theorems: Proved that the universe began in a state of infinite density using general relativity
- Collaborated with Roger Penrose: Advanced our understanding of gravitational singularities and black hole formation
| Concept | Hawking’s Contribution |
|---|---|
| Big Bang Singularity | Showed the universe likely began as a singularity (2) |
| General Relativity | Combined with quantum mechanics to transform cosmology |
| Gravitational Collapse | Explained fate of stars leading to black holes |
Revolutionizing Black Hole Physics
Before Hawking’s work, scientists believed black holes were inescapable voids where matter and even light could not escape(5). Hawking, using a blend of quantum theory and relativity, revealed that black holes emit radiation, contrary to all prior assumptions—this radiation later came to be known as Hawking radiation(5)(2)(3). This discovery reshaped theoretical physics and our understanding of the universe’s ultimate fate.
- Hawking Radiation: Proposed that black holes are not completely black; they emit tiny amounts of radiation and can eventually evaporate(2)(5)(3)
- Challenge to mainstream physics: Overturned the belief that black holes trap everything forever
“Black holes are not the eternal prisons they were once thought” — Stephen Hawking(3)
His insights inspired decades of research into quantum gravity and gave rise to new debates, such as the information paradox: what happens to information about matter that approaches a black hole?(3)
Groundbreaking Ideas: Black Holes and the Information Paradox
The fate of information within black holes perplexed physicists for years(3). At a 2015 conference in Sweden, Hawking proposed that information about a physical object entering a black hole is not destroyed but instead is stored in two dimensions at the event horizon itself. He left open the possibility that, under certain theoretical circumstances, the information could escape into another universe.
- Event horizon theory: Information may be retained in a 2D format on the outer boundary of the black hole
- Possibility of information escape: Proposed that information loss may not be permanent, challenging long-held assumptions
Popularizing Science: Books and Public Engagement
Stephen Hawking’s stature as a beloved public figure grew thanks to his ability to make complex cosmological topics accessible. His most famous book, A Brief History of Time, published in 1988, became an international bestseller, staying on the Sunday Times bestseller list for a record 237 weeks(4). Hawking’s other popular science books include:
- Black Holes and Baby Universes and Other Essays (1993)
- The Universe in a Nutshell (2001)
- My Brief History (2013)
- Collaborations with his daughter: Lucy Hawking, on children’s science books
Through his books, television appearances, and lectures, Hawking captured the imagination of people worldwide and stimulated interest in science and space exploration.

Personal Life, Family and Legacy
Despite his illness, Hawking married twice and had three children(5). Lucy, Robert, and Tim Hawking issued a heartfelt statement on his passing in 2018, remembering him as not only a pioneering scientist but also an extraordinary man(5). His life story demonstrates remarkable resilience, humility, and humor—qualities that made him a model for scientists and laypeople alike.
- Marriage: Twice married
- Children: Lucy, Robert, and Tim

Hawking’s death in March 2018 marked the end of a life that overcame incalculable odds and inspired countless scientists(5). His scientific vision and personal determination remain universally admired.
Frequently Asked Questions (FAQ)
Q: What is Hawking radiation?
A: Hawking radiation is the theoretical prediction that black holes emit thermal radiation, which means they can slowly lose mass and eventually evaporate(2)(3).
Q: How did Stephen Hawking change our understanding of black holes?
A: He combined quantum mechanics and general relativity to show that black holes are not perfect vacuums but instead emit radiation, revolutionizing the field of theoretical physics(2)(5).
Q: What was Stephen Hawking’s major impact on the Big Bang theory?
A: Hawking proved, using mathematical models, that the universe likely began with a singularity, lending strong support to the Big Bang model(2)(4).

- “We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the universe. That makes us something very special.”
- “Intelligence is the ability to adapt to change.”
- “Look up at the stars and not down at your feet. Try to make sense of what you see and wonder about what makes the universe exist.”
