2As you can see, there are a number of things in
this picture that just dont make sense
- No light
- No ancient reptiles
- No oceans
- No air
- Too hot for life
- No people on boats
3Plot
- Prof. Harwigg finds an ancient text by Icelander
Arne Saknussemm
- Goes down Sneffels mountain in Iceland
- Travels around the inside of the earth through a
series of caves
- Reaches the Central Sea
- Gets back to the surface through an eruption of
Stromboli, in Italy
4The Science Behind the Book
- Hollow Earth Theory
- Underground Water Theory
- Plate Tectonics
- Magnetic Pole
5HOLLOW EARTH THEORY
- Gazing around, I began to think of the theory
of the English captain who compared the earth to
a vast hollow sphere in the interior of which the
air is retained in a luminous state by means of
atmospheric pressure, while two stars, Pluto and
Proserpine, circled there in their mysterious
orbits. After all, suppose the old fellow was
right! - -Harry, looking at the electric light in
the cavern of the Central Sea
6Sir Edmund Halleys Theory
http//en.wikipedia.org/wiki/Hollow_Earth
- Idea developed in 1692
- Earth consists of four concentric spheres
- Suspended in atmospheres
- Atmospheres are luminous, possibly contain life
7Leonhard Eulers Theory
http//en.wikipedia.org/wiki/Hollow_Earth
- Developed in the 1700s
- A central sun inside the earth with a radius of
600mi
- Provided light to the inhabitants of earths
interior
8Sir John Leslies Theory
- 1829 Elements of Natural Philosophy, mentions
a hollow earth
- Idea of two suns within the earth, named Pluto
and Proserpine
- This is the English captain
- that Harry is talking about!
- Besides, as we approach the center, I except to
find it luminous
- -Prof. Hardwigg
9UNDERGROUND WATER THEORY
- A vast, limitless expanse of water, the end of
a lake if not of an ocean, spread before us,
until it was lost in the distance. . . . It was
in reality an ocean, with an the usual
characteristics of an inland sea, only horribly
wildso rigid, cold and savage. - -Harry, upon seeing the Central Sea

11May Actually be True . . . Kind of

- Discovered by Michael Wysession of Wash U this
past February
- Red shows unusually soft and weak rock believed
to be saturated with water
12The Beijing Anomaly
- Analyzed over 600,000 seismic waves
- Noticed that some slowed while passing through
the mantle under Asia
- As water is sucked under the crust, heated up,
rises into overlying regions of rock
- Volume at least as much as the Arctic Ocean
13PLATE TECTONICS
- This . . . island must have made its appearance
from out of the great world of waters at a
comparatively recent date. . . . If this really
be the case, its origin can be attributed to only
one causethat of the continued action of
subterranean fires. -
- -Harry, talking about Iceland
14Vernes Idea of Plate Tectonics
- Long before the existence of volcanoes, it was
composed of a solid body of massive trap rock
lifted bodily and slowly out of the sea, by the
action of the centrifugal force at work in the
earth.

15- At a later period in the worlds history, a
huge and mighty fissure must, reasoning by
analogy, have been dug diagonally from the
southwest to the northeast of the island, through
which by degrees flowed the volcanic crust.

16- . . . despite the enormous thickness and weight
of the upper crust, the mechanical forces of the
combustible gases below became so great, that
they actually upheaved the weighty back and made
for themselves huge and gigantic shafts. Hence
the volcanoes . . .

18MAGNETIC POLE
-
- Why, that the needle instead of dipping towards
the pole as it does on earth, in the northern
hemisphere, has an upward tendency.
19Really?
- This proves, I cried, that the great point
of magnetic attraction lies somewhere between the
surface of the earth and the spot we have
succeeded in reaching.

20Proof of Wavering
- . . . near the seventy-third degree of
latitude, where Sir James Ross discovered the
magnetic pole . . . .
- 1831 Northwest Passage, Ross located the
Magnetic North Pole
