The crux of the hollow earth theory is that the earth is a shell with walls about 800 miles thick. In the polar regions there are holes 1400 miles across, with edges that curve smoothly from the outside of the shell around to the inside.

Oct 5, 2022 · The research was published today in the journal Earth’s Future. The research challenges a claim in a 2018 research paper that repeated spreading of hollow glass microspheres, or HGMs, on young Arctic sea ice will increase reflectivity, protect it from the sun and therefore allow it to mature over time into highly reflective multi-year ice.

Since it was established by an Act of Congress in 1946, scientists at the Geophysical Institute have studied geophysical processes from the center of the Earth to the surface of the sun and beyond, turning data and observations into information useful for …

The Space Physics and Aeronomy research group studies the Earth’s geospace environment and the magnetospheres of other planets. Major topics investigated by the group are associated with the response of the magnetosphere, ionosphere and upper atmosphere to solar disturbances that reach the Earth after propagating through interplanetary space.

May 2, 2019 · Field and Sholtz shared their idea of spreading hollow glass beads over ice that floats on the northern ocean. After field testing the material on the surface of frozen lakes, they saw it increases sea ice’s reflectivity and can slow its melting. That, in turn, could help slow the Earth’s warming.

Mar 13, 2025 · Since it was established by an Act of Congress in 1946, scientists at the Geophysical Institute have studied geophysical processes from the center of the Earth to the surface of the sun and beyond, turning data and observations into information useful for state, Arctic and national priorities.

May 25, 2018 · In 2013, Dom Winski of Dartmouth College spent a few weeks living on Mount Hunter’s high plateau. He and a team from Dartmouth, the University of Maine and the University of New Hampshire twisted a hollow drill bit into ice and snow on top of the mountain.

Feb 13, 2025 · Mostly composed of ground-up rock and water, lubricating fluid is pumped down the center of the hollow drill stem, and emerges again at the surface, carrying the pulverized rock and other unspeakable things. This is necessary to lubricate the drill shaft, cool the hole, and carry away the detritus that the drilling has created.

May 19, 1993 · The whole leaf is flat on its inner surface, rounded on the exterior. Looking at a cross section of a cattail leaf is eerily like looking at a cross section of a modern airplane wing in miniature. The curve, the light but strong hollow structures within, even the fibrous sheathing all could be taken as high-tech design.

Dec 3, 1997 · "No, dear," I said to my then-young daughter. "The past tense of pingo is not pingwent." It's the sort of comment likely to be needed in a household with an eager new reader and an array of books on subjects from the trivial to the technical.
