Cosmic collision

Each of the following events happened on June 30. Your challenge is to put them in the order in which they occurred by year, earliest to latest. Answers at the bottom!

  • A) A fiery explosion rocks Siberia’s Tunguska region, flattening 800 square miles of forest. Believed to be caused by an asteroid or comet, it remains Earth’s biggest cosmic collision in recorded history, releasing equivalent energy of 10-15 megatons of TNT (~1,000x more powerful than the Hiroshima atomic bomb).
  • B) Jean Francois Gravelet, a Frenchman known as Charles Blondin, becomes the first person to walk across Niagara Falls on a tightrope. Some 5,000 spectators watch as Blondin travels 1,100 feet along a 2-inch-wide cable strung 160 feet above the Niagara gorge.
  • C) Albert Einstein publishes “On the Electrodynamics of Moving Bodies,” a paper that sets out his theory of special relativity, in the German physics journal Annalen der Physik. It’s often regarded as one of the most important papers ever published in the field of physics.
  • D) China’s Danyang-Kunshan Grand Bridge opens to the public, becoming the longest bridge in the world. It extends 102.4 miles between Nanjing and Shanghai, the most populated city in China.

Hint: The Danyang-Kunshan Grand Bridge took 4 years to build
