"Pengea" was a hypothetical supercontinent proposed by scientists that existed around 335-175 million years ago. It is believed to have formed before the breakup of Pangaea, and it was located in the Southern Hemisphere. Pengea's existence helps explain certain geological features found on different continents today.

Alfred Wegener proposed that all landforms were once part of a single supercontinent called "Pangaea." He introduced this concept in the early 20th century, suggesting that Pangaea existed around 300 million years ago and gradually drifted apart due to continental drift. Wegener's ideas laid the groundwork for the modern theory of plate tectonics.
Existence.
Atomic theory does not really refer to electrons---indeed, when it was first created they did not even know electrons existed, and the modern reinterpretation of its postulates (in light of our knowledge of subatomic particles, fission, fusion, and isotopes) does not talk specifically about electrons either. Now based on your question, I presume that what you are looking for is that we cannot know both the position and momentum of an electron simultaneously. This is the application of Heisenburg's uncertainty principle to electrons. It is the reason why we talk about the location of electrons in terms of probabilities of finding them somewhere within the region of space defined by orbitals.
It would have 26 electrons - if it existed.
They have always done that, ever since atoms and electrons existed.
Alfred Wegener, a German meteorologist, first proposed the theory of continental drift in 1912. He suggested that a supercontinent he named Pangaea had existed and later broke apart to form the continents as we know them today.
I don't think anybody proposed the laws of gravity. The laws of gravity have existed since the beginning of time and the beginning of the universe.
Wegener named the supercontinent he proposed "Pangaea," which he believed existed before breaking apart into the continents we have today. The name "Pangaea" is derived from Greek, meaning "all lands."
John Dalton, a British scientist, offered proof of the existence of atoms in the nineteenth century through his atomic theory. Dalton's theory proposed that elements are made up of atoms that are identical in mass and properties, and that compounds are formed through the combination of these atoms in simple whole-number ratios.

Alfred Wegener called the large supercontinent that once existed Pangaea.
Because they are alive today, birds are dinosaurs. And because of fossils.
The concept of Pangaea, the supercontinent that existed during the late Paleozoic and early Mesozoic eras, was first proposed in the early 20th century. Alfred Wegener, a German scientist, introduced the idea of Pangaea in 1912 as part of his theory of continental drift.
Alfred Wegner proposed the concept of a supercontinent called Pangaea, which he believed existed around 300 million years ago. Wegner suggested that Pangaea later split apart to form the continents that we see today.
Around the 50's discovered. Scientist estimated him to be around 146 years.
