In the UVS worldview, the Earth could occasionally encounter some significant planetary barycenters[w] or their Lagrangian points[w], and thus could resonate with its effects of torque-induced precession[w] to form such dual-core craters on the Earth's crust. Heuristically[w], the induced precession[w] effects of these barycenters or their Lagrangian points could intrinsically render their hyperspherical standing waves[w] to form magma[w] with increased geothermal gradient[w] in the resonated Earth's crust to cause soil liquefaction[w]. The hyperspherical standing waves in liquefied crust could thus manifest all possible transformations of torus[w] to form the peculiar dual-core craters on the Earth's crust. Barringer Crater

The UVS research predicates a peculiar type of dual-core craters were formed by the hyperspherical standing waves resonated in the Earth's crust.

See the UVS topic on "Sunspot" that elaborates on how the resonated standing waves of the torus transformed hypersphere could vortically manifest as the observed dual-core sunspot clusters.

The structure of a torus standing wave is fundamentally modulated by its dual-core vortical hypersphere[w) resonated in viscous medium. Its harmonics resonated at different angular phases could transform it as a nested multi-core vortical hypersphere of n-sphere when superpositioned[w] in a steady-state. Note: The animation on right illustrates how a torus[w] could transform. It shows as the distance to the axis of revolution decreases, the ring torus becomes a horn torus, then a spindle torus, and when the distance approaches zero, the torus will resemble a sphere.

Watch a video clip on "Acoustic water dance / Parametric waves" that demonstrate sound waves of various frequencies when induced in a liquid medium, could resonate to manifest different forms of standing waves. These could manifest as the waveform of a raised rim with a multi-core formed at the center(0:28"), the waveform of concentric circles with a dual-core (1':00"), or the more complex waveform of a nested cluster of multi-core parabolic structure with raised rims (1':28"). Watch another video clip on "Non-Newtonian Fluid on a Speaker Cone" that demonstrate how standing waves of raised structures could be formed with resonated frequencies in high viscosity medium.

The cognitive paradox that renders the misconception of impact crater for a type of craters with the peculiar dual-core characteristic, was thus meticulously resolved with its underlying vortical structure and mechanism explicated.

The grounding for its epistemic theories of truth: The underlying vortical structure and mechanism of a peculiar type of crater as explicated with its hypothetical construct based on the UVS model, elucidated its delusional observations that render its misconceptions, mysteries, and anomalies. Thus, its cognitive paradox could be meticulously resolved, and all the related natural phenomena were then qualitatively analysed in the conceptual framework of UVS by inductive reasoning for explicating with their empirical evidence to predicate by abductive reasoning.

See the UVS topic on "Overviews of the UVS research" that elaborates on its visual grounded theory for the evaluations of natural phenomena.

Vortically manifested dual-core craters

From the UVS perspective, when the Earth is subjected to a significant torque-induced precession[w] of a planetary barycenter, it could harmonically spawn all possible forms of torus[w] induced standing waves on its crust. And the intrinsically resonated vortical torsion force of its manifested vortical hypersphere could cause soil liquefaction in the resonated Earth's crust[w].

Evidently, the characteristics of dual-core vortical structure manifested in such craters with the peculiar torus geometries of ring torus[m], spindle torus[m], and horn torus[m], suggest these craters were formed by the vortical hyperspheres of liquefied soil that have had manifested in the Earth's crust. A substantial torque-induced precession extrinsically perturbed the Earth, could form the nested torus force field of a vortical hypersphere with intrinsic two-axis spin to spawn at its vertex[w] in the Earth's crust, which is intrinsically formed by a strongly resonated torque-free precession[w] at the focal point.

Spindle torus.

Horn torus.

This vortical torsion force intrinsically manifested with a high pressure ring torus force field in the Earth's crust, could raise up the liquefied soil around its vortical rim. And with its vortically generated low-pressure system at the hypocenter[w] of its vortical hypersphere, it could thus form a dominant dual-core crater on the Earth's crust.

With the complex waveform of a nested cluster of vortical hypersphere resonated on the surface of the Earth, it could also intrinsically form a complex nested crater with concentric raised rims and a central uplifted structure. Examples of the craters with such a formation is the Clearwater West crater[w] with raised concentric rims and a central peak, the Seongsan Ilchulbong crater[w] formed with the raised central core of a bowl-shaped structure in a much larger basin[m], and the basin of Steinheim crater[m] with a prominent bowl-shaped central uplift.

The terrain map on right showed two very similar structured stratovolcanoes[w] of Mount Natib[w] and Mount Mariveles[w] in Philippines. As a whole in a raised rim, these two volcanoes apparently are showing the nested dual-core characteristics of a composite nested horn torus hypersphere pair nested in a larger ring torus hypersphere. Each of these two volcanoes have a pair of summit craters and a central peak formed at the convergence point of its two asymmetrical calderas[w]. At the peak of Mount Natib, there are two small craters (cyan circles in the far right image) next to the summit. The smaller caldera of Mount Natib (large grey oval) is a crater formed as a basin with raised rim among other clusters of overlapped craters laid on the mountain's slope. Inside this caldera, there is a central raised structure with a dominant pair of concentric raised rims and their nested dual-core craters formed at their two peaks.

Many renowned impact craters[w] around the world are also demonstrating such raised rims and the dual-core characteristics at the centers of their craters. To illustrate a few, they are:

The Barringer Meteor Crater in Arizona[w] The image on the near right showed the patterns of a dominant dual-core vortical structure at the center of this crater, which is distinctly visible among the other overlapped circular patterns formed around it. The image on the far right showed the patterns of the dual-core vortical structure from a lower elevation. The diameter of this crater is approximately 1.2 kilometer.

The Wolfe Creek Crater in Australia[w] This crater has a distinct concentric structure with some overlapped circular patterns formed within the crater. The inserted image highlighted the characteristics of a dominant dual-core vortical structure formed in the charred inner core. The image on far right as highlighted showed this crater was actually formed in a much larger cluster of craters that have less obvious big and small circles of overlapped dual-core vortical patterns.

The twin impact craters of Clearwater Lake[w] These twin craters in Clearwater Lake distinctly demonstrated the characteristics of a dominant dual-core vortical structure with the vague appearances of their supposedly raised outer ring torus structures. The crater in Clearwater West demonstrated it is a nested ring torus structure with a smaller center core outlined but is fully submerged in the water. The image on far right as highlighted showed the concentric ring of the two craters, and also showed there is another huge but less obvious concentric ring pattern with a tri-core.

The Lake Mecatina Meteor Crater in Quebec[m] These twin craters in the Lake Mecatina distinctly demonstrated the characteristics of a dominant dual-core vortical structure formed in a basin. The image on far right as highlighted showed the basin and the ring torus structures of the two craters. Note: A geological study by Emeritus professor Gerencher revealed the Mecatina structure in Quebec is in fact NOT a meteorite impact crater.

Despite the meteorite impact hazards are real threats, they must not be mixed up with those craters that were intrinsically formed by the dual-core vortical hypersphere of liquefied soil that have had manifested on the Earth's crust. And the misconception for the causality of such dual-core craters is a huge geology concern that has to be seriously reckoned with.

This is a list of some classified impact craters that are also showing the dual-core or multi-core peculiarities:

- Tswaing crater in South Africa[w]
- Vredefort crater in South Africa[w]
- Karakul impact crater inTajikistan[w]
- Beaver Crater in United States[w]

Many renowned craters around the world that are known to be not caused by impact events[w], had also distinctly displayed such peculiar dual-core patterns in their remnants.

The Eye of the Sahara[w] is a concentric geology structure believed to be caused by a laccolithic[w] thrust. And right in the inner core, there is a distinct dual-core pattern formed among the other overlapped circular patterns. The aerial image of the Croatia Plitvice Lakes National Park as shown demonstrated a cluster of craters. It has two dominant craters that demonstrated the dual-core characteristic of a ring torus hypersphere. And one of the craters distinctly demonstrated the dual-core characteristic of a nested spindle torus hypersphere.

The Google Earth image of Iceland[m] shows there are numerous overlapped clusters of dual-core craters with raised rims and bowl-shaped raised central regions. As highlighted in the image at the far right, it showed this island is the tip of a huge nested dual-core structure, which could be the raised central region formed in a much larger basin. See an externally linked report that suggests Iceland may be the tip of a sunken continent.

These are some craters not caused by impact events but are also showing the dual-core or multi-core peculiarities:

- The Lost City of Heracleion in Egypt[m]
- Mount Dendi in Ethiopia[w]
- Diamond Head Crater in Hawaii[m]
- The Tri-Colored Crater Lake of Kelimutu in Indonesia[m]
- The Pompeii megacaldera in Italy[m]
- The two submit craters of Mount Mariveles[w] in Philippines[w]
- The two submit craters of Mount Natib[w] in Philippines[w]
- Al Wahbah crater in Saudi Arabia[w]
- Seongsan Ilchulbong crater in South Korea[w]
- The twin craters of Hallasan mountain in South Korea[m]
- The dual-core crater of Yeosu in South Korea[w]

By examine the satellite images with Google Earth[m] closely, it would show countless big and small clusters of overlapped dual-core and multi-core craters formed all over the globe. And they are clearly visible on landmasses such as around the Michigan Basin[m], and on sea beds such as around the Gulf of Mexico[m]. From the UVS perspective, all these dual-core and multi-core craters were formed by the vortical hyperspheres of liquefied soil that have had manifested in the Earth's crust. These clearly visible dual-core and multi-core vortical patterns formed in their basin, are strong evidence these craters were formed by the vortical hyperspheres of liquefied soil that have had spawned in the Earth's crust. See the UVS topic on "Tunguska event" that elaborates on how the Yenisei basin in Siberia with numerous clusters of overlapped craters could be vortically formed.
