Dear Ms Stardust ,

Thank you for this essay. What you speak of here is called "Continental Drift". The hypothesis of continental drift became part of the larger theory of plate tectonics.

South America and Africa are moving apart at an average of 5.7 cm per year because the sea floor is spreading along the Mid-Atlantic Ridge. This is comparable to the growth speed of a fingernail.

The fastest recorded sea floor spreading takes place along the East Pacific Rise at 17.2 cm per year.

Evidence for continental drift is now extensive, in the form of plant and animal fossils of the same age found around different continent shores, suggesting that these shores were once joined: the fossils of the freshwater crocodile, found in Brazil and South Africa, are one example. Another is the discovery of fossils of the aquatic reptile Lystrosaurus from rocks of the same age from locations in South America, Africa, and Antarctica. There is also living evidence - the same animals being found on two continents. An example of this is a particular earthworm found in South America and South Africa.

On the topic of Neutrinos....yes, they are everywhere, hardly have any mass, and go through all substances.

Thank you for sharing...as this part of what I teach, and am educated in. Great write!
