What is the Karman line and how it defines the edge of space

In July 2021, Richard Branson and Jeff Bezos went to space. But the question about edge of space remains open even after their successful flights.

In this article, you will learn what the Karman line is, which says right the same thing. Considering recent events of the first two tourists sent to space by the private companies, this line may be changed, which could lead to reviewing a few historical facts of who has been beyond the Earth and who has not.

In the 20th century, there was a Hungarian physicist Theodore von Kármán. He was into aeronautics and astronautics and spent his whole life working in these fields.

He was born in Budapest, however, he did most of his research in the USA. His contribution in the fields of aeronautics and astronautics is immeasurable because of his theories of non-elastic buckling, stability of laminar flow, and many others.

Kármán also was the first person to calculate where the Earth’s atmosphere becomes too thin for airplanes to fly. In 1957, he set this boundary at 275,000 ft (83.82 km), or Von Karman line.
