A hollow Earth would be less than % of its current mass. The gravity on a hollow Earth would be so weak, it wouldn’t be enough for you to stick to the planet. You’d fly away into space. That’s, of course, if you could make it through all the solar radiation. Perhaps the most important is that the hollow Earth theory was propagated by the astronomer Edmond Halley - as in Halley's comet. The idea of "Hollow Earth" was brought to life and made exciting by the science fiction author Jules Verne, who wrote the novel " Journey to the Center of the Earth " in
The Hollow Earth is a concept proposing that the planet Earth is entirely hollow or contains a substantial interior space. Notably suggested by Edmond Halley in the late 17th century, the notion was disproved, first tentatively by Pierre Bouguer inthen definitively by Charles Hutton in his Schiehallion experiment around It was still occasionally defended through the midth century, notably by John Cleves Symmes Jr.
Reynoldsbut by this time it was part of popular pseudoscience and no longer a scientifically viable hypothesis. The concept of a hollow Earth still recurs in folklore and as a premise for subterranean fictiona subgenre of adventure fiction. In ancient times, the concept of a subterranean land inside what temperature should my grow tent be Earth appeared in mythologyfolklore and legends. The idea of a subterranean realm is also mentioned in Tibetan Buddhist belief.
According to the Ancient Greeksthere were caverns under the surface which were entrances leading to the underworldsome of which were the caverns at Tainaron in Lakoniaat Troezen in Argolisat Ephya in Thesprotiaat Herakleia in Pontosand in Ermioni. In Celtic mythology there is a legend of a cave called " Cruachan ", also known how to play what a wonderful world on acoustic guitar "Ireland's gate to Hell", a mythical and ancient cave from which according to legend strange creatures would emerge and be seen on the surface of the Earth.
In Hindu mythology, the underworld is referred to as Patala. In the Bengali version of the Hindu epic Ramayanait has been depicted how Rama and Lakshmana were taken by the king of the underworld Ahiravanbrother of the demon king Ravana. Later on they were rescued by Hanuman. The Angami Naga tribes of India claim that their ancestors emerged in ancient times from a subterranean land inside the Earth.
Natives of the Trobriand Islands believe that their ancestors had come from a subterranean land through a cavern hole called "Obukula". In the middle agesan ancient German myth held how to play with a paddle ball some mountains located between Eisenach and Gotha hold a portal to the inner Earth.
A Russian legend says the Samoyedsan ancient Siberian tribetraveled to a cavern city to live inside the Earth. In Native American mythologyit is said that the ancestors of the Mandan people in ancient times emerged from a subterranean land through a cave at the north side of the Missouri River. Brazilian Indianswho live alongside the Parima River in Brazil, claim that their forefathers emerged in ancient times from an underground land, and that many of their ancestors still remained inside the Earth.
Ancestors of the Inca supposedly came from caves which are located east of CuzcoPeru. Edmond Halley in  conjectured that the Earth might consist of a hollow shell about km mi thick, two inner concentric shells and an innermost core. Atmospheres separate these shells, and each shell has its own magnetic poles. The spheres rotate at different speeds. Halley proposed this scheme in order to explain anomalous compass readings. He envisaged the atmosphere inside as luminous and possibly inhabited and speculated that escaping gas caused the Aurora Borealis.
Le Clerc Milfort in led a journey with hundreds of Creek Indians to a series of caverns near the Red River above the junction of the Mississippi River. According to Milfort the original Creek Indian ancestors are believed to have emerged out to the surface of the Earth in ancient times from the caverns.
Milfort also claimed the caverns they saw "could easily contain 15, — 20, families. InJohn Cleves Symmes, Jr. Symmes became the most famous of the early Hollow Earth proponents, and Hamilton, Ohio even has a monument to him and his ideas.
Jeremiah Reynolds also delivered lectures on the "Hollow Earth" and argued for an expedition. Reynolds went on an expedition to Antarctica himself but missed joining the Great U. Exploring Expedition of —, even though that venture was a result of his agitation. Though Symmes himself never wrote a book about his ideas, several authors published works discussing his ideas. Ina professor W. Inin Journey to the Center of the Earth  Jules Verne describes a hollow Earth containing two rotating binary stars, named Pluto and Proserpine.
This influenced some early Hollow Earth proponents. According to Marshall Gardner, both the Eskimo and Mongolian peoples had come from the interior of the Earth through an entrance at the North pole. He supported the idea of a hollow Earth, but without interior shells or inner sun. The spiritualist writer Walburga, Lady Paget in her book Colloquies with an unseen friend was an early writer to mention the hollow Earth hypothesis. She claimed that cities exist beneath a desert, which is where the people of Atlantis moved.
She said an entrance to the subterranean kingdom will be discovered in the 21st century. Marshall Gardner wrote A Journey to the Earth's Interior in and published an expanded edition in He placed an interior sun in the Earth and built a working model of the Hollow Earth which he patented U.
Patent 1, Gardner made no mention of Reed, but did criticize Symmes for his ideas. Around the same time, Vladimir Obruchev wrote a novel titled Plutoniain which the Hollow Earth possessed an inner Sun and was inhabited by prehistoric species.
The interior was connected with the surface by an opening in the Arctic. Ossendowski said he was told about a subterranean kingdom that exists inside the Earth. It was known to Buddhists as Agharti. George Papashvily in his Anything Can Happen claimed the discovery in the Caucasus mountains of a cavern containing human skeletons "with heads as big as bushel baskets" and an ancient tunnel leading to the center of the Earth.
One man entered the tunnel and never returned. Novelist Lobsang Rampa in his book The Cave of the Ancients said an underground chamber system exists beneath the Himalayas of Tibetfilled with ancient machineryrecords and treasure. According to the ancient astronaut writer Peter Kolosimo a robot was seen entering a tunnel below a monastery in Mongolia. Kolosimo also claimed a light was seen from underground in Azerbaijan.
A book by a "Dr. Raymond Bernard " which appeared inThe Hollow Earthexemplifies the idea of UFOs coming from inside the Earth, and adds the idea that the Ring Nebula proves the existence of hollow worlds, as well as speculation on the fate of Atlantis and the origin of flying saucers.
The science fiction pulp magazine Amazing Stories promoted one such idea from to as "The Shaver Mystery". The magazine's editor, Ray Palmer what if the earth was hollow, ran a series of stories by Richard Sharpe Shaverclaiming that a superior pre-historic race had built a honeycomb of caves in the Earth, and that their degenerate descendants, known as "Dero", live there still, using the fantastic machines abandoned by the ancient races to torment those of us living on the surface.
As one characteristic of this torment, Shaver described "voices" that purportedly came from no explainable source. Thousands of readers wrote to affirm that they, too, had heard the fiendish voices from inside the Earth. Hollow Earth proponents have claimed a number of different locations for the entrances which lead inside the Earth.
Other than the North and South poles, entrances in what if the earth was hollow which have been cited include: Paris in France,  Staffordshire in England,  Montreal in Canada,  Hangchow in China,  and the Amazon Rainforest.
Instead of saying that humans live on the outside surface of a hollow planet—sometimes called a "convex" Hollow Earth hypothesis—some have claimed humans live on the inside surface of a hollow spherical world, so that our universe itself lies in that world's interior. This has been called the "concave" Hollow Earth hypothesis or skycentrism. The main colony survives as a preserved Florida state historic site, at Estero, Floridabut all of Teed's followers have now died.
Teed's followers claimed to have experimentally verified the concavity of the Earth's curvature, through surveys of the Florida coastline making use of "rectilineator" equipment.
It has even been reported, although apparently without historical documentation, that Adolf Hitler was influenced by concave Hollow Earth ideas and sent an expedition in an unsuccessful attempt to spy on the British fleet by pointing infrared cameras up at the sky.
The Egyptian mathematician Mostafa Abdelkader wrote several scholarly papers working out a detailed mapping of the Concave Earth model. According to Gardner, this hypothesis posits that light rays travel in circular paths, and slow as they approach the center of the spherical star-filled cavern.
No energy can reach the center of the cavern, which corresponds to no point a finite distance away from Earth in what is on broadcast tv tonight widely accepted scientific cosmology.
A drill, Gardner says, would lengthen as it traveled away from the cavern and eventually pass through the "point at infinity" corresponding to the center of the Earth in the widely accepted scientific cosmology. Supposedly no experiment can distinguish between the two cosmologies. Gardner notes that "most mathematicians believe that an inside-out universe, with properly adjusted physical laws, is empirically irrefutable". Gardner rejects the concave Hollow Earth hypothesis on the basis of Occam's razor.
Purportedly verifiable hypotheses of a "Concave Hollow Earth" need to be distinguished from a thought experiment which defines a coordinate transformation such that the interior of the Earth becomes "exterior" what does it mean to ping a server the exterior becomes "interior".
The transformation entails corresponding changes to the forms of physical laws. This is not a hypothesis but an illustration of the fact that any description of the physical world can be equivalently expressed in more than one way. Arriving and climbing the volcano inthey conducted a Vertical Deflection experiment at two different altitudes to determine how local mass anomalies affected gravitational pull. In a paper Bouguer wrote a little over ten years later, Bouguer commented that his results had at least falsified the Hollow Earth Theory.
In what if the earth was hollow, Nevil Maskelyne proposed to repeat the same experiment to the Royal Society. Within the same year, the Committee of Attraction was formed and they sent Charles Mason to find the perfect candidate for the vertical deflection experiment.
Mason found the Schiehallion mountain, where the experiment took place and not only supported the earlier Chimborazo Experiment but yielded far greater results. The picture of the structure of the Earth that has been arrived at through the study of seismic waves  is quite different from a fully hollow Earth.
The time it takes for seismic waves to travel through and around the What does standard form mean directly contradicts a fully hollow sphere. The evidence indicates the Earth is mostly how to do a life table with solid rock mantle and crustliquid nickel-iron alloy outer coreand solid nickel-iron inner core. Another set of scientific arguments against a Hollow Earth or any hollow planet comes from gravity.
Massive objects tend to clump together gravitationally, creating non-hollow spherical objects such as stars and planets. The solid spheroid is the best way in which to minimize the gravitational potential energy of a rotating physical object; having hollowness is unfavorable in the energetic sense. In addition, ordinary matter is not strong enough to support a hollow shape of planetary size against the force of gravity; a planet-sized hollow shell with the known, observed thickness what is a disclosure agreement the Earth's crust would not what harry potter house are you in realistic able to achieve hydrostatic equilibrium with its own mass and would collapse.
Based upon the size of the Earth and the force of gravity on its surface, the average density of the planet Earth is 5. If any significant portion of the Earth were hollow, the average density would be much lower than that of surface rocks. The only way for Earth to have the force of gravity that it does is for much more dense material to make up a large part of the interior.
Drilling holes does not provide direct evidence against the hypothesis. The deepest hole drilled to date is the Kola Superdeep Borehole with a true vertical drill-depth of more than 7. However, the distance to the center of the Earth is nearly 4, miles 6, kilometers.
Oil wells with longer depths are not vertical wells; the total depths quoted are measured depth MD or equivalently, along-hole depth AHD as these wells are deviated to horizontal.
Their true vertical depth TVD is typically less than 2. The idea of a hollow Earth is a common element of fiction, appearing as early as What to expect at antenatal classes Holberg 's novel Nicolai Klimii iter subterraneum Niels Klim's Underground Travelsin which Nicolai Klim falls through a cave while spelunking and spends several years living on a smaller globe both within and the inside of the outer shell.
In William Henry Hudson 's romance, A Crystal Agethe protagonist falls down a hill into a Utopian paradise; since he falls into this world, it is sometimes classified as a hollow Earth story; although the hero himself thinks he may have traveled forward in time by millennia.
The Earth is hollow, giants exist, and we're surrounded by reptile people. It gets weirder.
Jul 31, · A hollow Earth would also lose a whole lot of mass, since most of it is accumulated in the planet’s inner part – the core and the mantle. We’re not just talking a few kilos, like what you put on during your last visit to Grandma’s, but rather sextillion tonnes. A hollow Earth would be less than % of its current mass.

Here’s an interesting scenario: Suppose that the Earth is not only hollow, but has the same mass as the solid Earth we are all familiar with. Surface gravity is the same as it always was: meters per second squared, or feet per second squ.
What Earth do you live on? A round one? Flat one? Maybe your world is resting on the back of a huge cosmic turtle? What about a hollow Earth? How would the laws of physics work on that hollow Earth? Would we be able to dig a hole all the way to its center? And if we did, what would being in that center feel like? Learning about how our world works took a lot of time, and brought out some bizarre theories.
One scientist even decided that the Earth was an inverted sphere, with the entire Universe hidden inside. Hollow Earth was also on the list of possibilities. But how would a planet like that work? A hollow Earth would collapse inwards on itself and become a smaller sphere.
Because of gravity, one of the four fundamental forces in the Universe. Gravity would bring all parts of the crust toward one another, making the hollow Earth just impossible.
Most likely, there would be absolutely no life on the planet. Because, for starters, there would be no atmosphere. The atmosphere of the Earth protects us from solar winds and space radiation. No core means no magnetic field, and no magnetic field means that the Earth would be pretty dead. A hollow Earth would be less than 0. The surface of that hollow Earth would be a very hostile place. Drifting inside the Earth without a spacesuit would be like stepping into the vacuum of space.
