Expanding Earth theory

growing earth theory (expanding)

The Expanding Earth theory (Growing Earth theory) with various geological and visual interpretations to consider, has some intriguing ideas.

  • The continents form a nearly perfect Pangea supercontinent on a planet 80% its present diameter, on our present size globe there are gaps.

  • Geology suggests that all the ocean crust rock is 200 million years young or younger. Covering about 2/3rds of the planets surface, with new basaltic rock extruding out and spreading from the middle of the oceans floors.
  • The Earth's continents appear to fit together on a much smaller planet, to form a 'supercontinent' that would be the whole Earth's surface.

In geology, a supercontinent is the assembly of most or all of the Earth's continental blocks or cratons to form a single large landmass ... Supercontinents have assembled and dispersed multiple times in the geologic past.

Supercontinent names: Ur (Vaalbara), Kenorland, Protopangea-Paleopangea, Columbia (Nuna), Rodinia, Pannotia, Pangaea.

Ocean floor rock is new, thin and different

Most of our globes actual surface, differs to land rock. Peer reviewed theories also state relatively not very thick. Dating techniques suggest it is very very fresh.

is the earth planet still growing expandingOceanic crust underlies most of the two-thirds of the Earth’s surface which is covered by the oceans. It has a remarkably uniform composition (mostly 49% ± 2% SiO2) and thickness (mostly 7 ± 1 km).

The ocean floor is the most dynamic part of the Earth’s surface. As a result, no part of the oceanic crust existing today is more than 200 million years old, which is less than 5% of the age of the Earth itself.

In a thought experiment what could happen if the Earth grows or expands?

Articles considering, in theory, a globe expansion interpretation. Could material and life from the formation of the planet, and just after, have survived these processes?

Growing Earth Theory (Expanding Earth Theory)

Growing Earth (Expanding Earth hypothesis) suggest that instead of the supercontinents theory the planet has expanded from its original supercontinent that was the whole Earth's surface, or, fitted together better on a planet with a smaller volume.

Over the centuries there have been a lot of theories about a hollow earth and an expanding Earth and how or what processes could cause a planet to grow.

The free video below is by Neal Adams, who has rebooted the hypothesis and discussion/arguments about if the Earth has expanded in the past. Neil Adams has his own unique ideas about the mechanics of how the planet could have grown. They are not necessarily what others who are interested in exploring the idea of the possibility of a reduced or increased planet diameter.

Expansion and contraction pains?

Could the planet have had periods of increasing its size, decreasing its surface area, expanded, got smaller ... a few times to explain multiple supercontinents and orogeny (mountain building periods)?

Exchanging Earth

expanding earth energy puzzle space tornadoesBut how or what would trigger, cause, energise an Expanding Earth? What processes or mechanism could help with a Growing Earth?

Could the energy and perhaps if extra mass is needed, come from what seems to be planet Earth receiving and exchanging energy and molecules/matter with our Sun and perhaps in a circuit with our solar system?

With the other solar system bodies such as planets, moons, active asteroids and comets part of a plasma circuit and solar system engine?

    I have a question that is quite interesting about how the earth is expanding. I had the assumption that if the earth expands due to space also expands. It is connected with the big bang theory. if the assumptions that have the possibility?

      Probably not. I think it’s more a matter of hot, compressed matter being expelled into a low pressure environment. This would allow material within that lava to boil, creating a more foamy rock as it cooled. This would displace more space than the (pressurized) liquid lava it came from.
