Extinction of the dinosaurs.
Alfred Wegener, a German scientist, proposed the theory of Pangaea in the early 20th century. He suggested that the continents were once joined together in a supercontinent that later drifted apart to their current positions.

Scientists refer to the landmass that all continents were once part of as "Pangaea." This supercontinent existed approximately 335 million years ago before it started breaking apart into the continents we know today.
The supercontinent was named Pangaea by Alfred Wegener. It was theorized that Pangaea existed during the late Paleozoic and early Mesozoic eras.
The Earth never collapsed. In the beginning of formation (about 4.6 billion years ago), however, it is theorized that a protoplanet, the size of Mars, sideswiped the Earth and caused a portion of both to break apart. The pieces came together and formed the Moon. It is also theorized that the Earth became a snow ball twice. There were also asteroid impacts on Earth, some severe enough to end most of life, but the Earth itself stayed intact.

Louis de Broglie theorized that matter, like electrons and other particles, could exhibit wave-like properties. This led to the development of wave-particle duality in quantum mechanics, where particles can act as both particles and waves. His work earned him the Nobel Prize in Physics in 1929.
