The Fascinating Origin of the Term "Black Hole" Explained
Written on
Chapter 1: The Historical Context
The term "black hole" has an intriguing history tied to a dark episode in British India. A significant event involved an Indian nawab who imprisoned 122 British individuals in a dim, confining cell, which later came to be known as a black hole.
The concept of a black hole describes the final phase of a star's life, where it collapses under its own gravitational force following a supernova explosion. But who coined the term, and what is its connection to British colonial history?
Section 1.1: The East India Company’s Role
Initially established as a trading entity, the East India Company focused on the lucrative spice trade, importing spices from India and selling them at a premium in Britain. This drew competition from other European powers such as the French and Dutch, who sought to undermine British trading interests.
The British established trading posts in Madras (now Chennai) but later relocated to Calcutta due to its greater economic potential. To protect their investments, they built Fort William. However, as Dutch forces began encroaching on British trade, tensions escalated.
Subsection 1.1.1: The Siege of Fort William
Siraj ud Daulah, the Nawab of Bengal, opposed the fortifications at Fort William. He demanded their removal within a week, but the British refused. Consequently, Siraj besieged the fort, resulting in a British surrender. The captured British, numbering 122—including women and children—were confined in a poorly lit cell with minimal ventilation, food, or water. The overcrowded conditions led to a tragic stampede, claiming many lives. When the cell was finally opened the next morning, only 32 individuals had survived. This harrowing event was dubbed the "Black Hole" by British newspapers, reflecting the grim circumstances the captives endured.
Section 1.2: The Scientific Connection
The term "black hole" evolved from this historical narrative into a scientific concept.
Dr. Becky Smethurst, in her book A Brief History of Black Holes: And Why Almost Everything You Know About Them Is Wrong, discusses how Robert H. Dicke likened the gravitational collapse of a star to the incident in Calcutta. As a star's core becomes densely packed with molecules, it collapses under immense pressure, leading to the formation of a black hole. This analogy solidified the term's usage in scientific discourse.
