00:00 Mount Everest is the tallest mountain in the world, standing at 8,848.86 meters or 29,031.7 feet.

01:52 Mount Everest was determined to be the tallest mountain in the world in 1852 by an Indian mathematician named Radhanth Sikdar, who calculated its height to be exactly 29,000 feet.

03:32 The real beginning of Everest exploration began with the 1921 British Mount Everest Reconnaissance Expedition, which aimed to figure out how close they could get to the mountain and what approaches up the mountain might have been possible.

05:07 The 1921 British Mount Everest Reconnaissance Expedition used bottled oxygen and faced extreme heights, setting altitude records but ultimately failing to reach the summit.

06:44 The 1924 British Mount Everest expedition resulted in the disappearance of George Mallory and Andrew Irving, and subsequent attempts to reach the summit were unsuccessful until Nepal opened itself up to the outside world and the Swiss expedition, with the help of Sherpa climbers, broke the 1924 altitude record but did not reach the peak.

08:27 In 1953, a British expedition led by Colonel John Hunt successfully reached the summit of Mount Everest, with Edmund Hillary and Ten Zignorge being the first to reach the peak.

10:08 Since the first successful summit in 1953, the number of people reaching the summit of Mount Everest has increased significantly, with over 6,000 individuals reaching the summit as of January 2021, including record holders such as Kami Riedesherpke who has reached the summit 25 times and Jordan Romero who became the youngest person to reach the summit at the age of 13 years and 10 months old in 2010.
