Scientists are predicting that a mile-deep volcano off the U.S. West Coast will erupt this year. The Axial Seamount, an underwater volcano located about 300 miles off the coast of Oregon, is ...
Contrary to the popular belief that the Earth was generally believed to be flat until a few hundred years ago, the spherical shape of the Earth (and other celestial bodies) has been widely accepted in the Western world (and universally by scholars) since at least the Hellenistic period (323 BCE–31 BCE), with the first known measurement of Earth's circumference conducted by Eratosthenes.
In the 20th century, geophysical methods were developed for remote exploration of the solid Earth and the ocean, and geophysics played an essential role in the development of the theory of plate tectonics. Geophysics is applied to societal needs, such as mineral resources, mitigation of natural hazards and environmental protection. [4]
The eponymous Silurians on Doctor Who are a race of reptilian humanoids from Earth's past, making their first appearance in the show in 1970. Frank and Schmidt cite Inherit the Stars, a 1977 novel by J. P. Hogan as containing a similar hypothesis, but also say they were surprised by how rarely the concept was explored in science fiction.

[32] [33] [34] Geophysics is commonly used to supplement the work of geologists in developing a comprehensive understanding of crustal geology, particularly in mineral and petroleum exploration. Seismologists use geophysics to understand plate tectonic movement, as well as predict seismic activity.
Barrow and Tipler believe that this is a valid conclusion from quantum mechanics, as John Archibald Wheeler has suggested, especially via his idea that information is the fundamental reality (see It from bit) and his Participatory anthropic principle (PAP) which is an interpretation of quantum mechanics associated with the ideas of John von ...
The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...
Much like how researchers believe humans mixed with Neanderthals in Eurasia before the Neanderthal went extinct, the study suggests that an “archaic hominin ghost population” could have ...
