Surface Mapping of Earth-like Exoplanets using Single Point Light Curves
Published on: May 10, 2020
Summary
Earth science models diverge, presenting paradoxes like a thin crust and an unrelated geoid. Reexamining assumptions about planetary composition and evolution is crucial for understanding terrestrial planets.
Area of Science:
- Geophysics, geochemistry, geology, and planetology.
Background:
- Divergent models for terrestrial planet composition and evolution exist.
- Evidence of differentiation and volcanism on small planets contrasts with hypotheses of homogeneous terrestrial mantles.
- Earth's thin crust and geoid anomalies challenge current mantle convection models.
Purpose of the Study:
- To reexamine long-held assumptions in earth sciences.
- To address paradoxes in planetary composition and evolution models.
Main Methods:
- Comparative analysis of geophysical, geochemical, geological, and planetological data.
- Evaluation of evidence from extraterrestrial sources.
Main Results:
- Contrasting evidence for planetary differentiation and mantle states (magma ocean vs. primitive).
- Earth's crust is exceptionally thin compared to the Moon.
- Geoid appears uncorrelated with mantle convection and plate tectonics.
- Mantle composition hypotheses (e.g., rich in olivine) conflict with extraterrestrial data.
Conclusions:
- Existing models for terrestrial planet evolution require reevaluation.
- Paradoxes necessitate a critical review of fundamental assumptions in earth sciences.

01:10Kepler's First Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. He formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe.
Polish astronomer Nikolaus Copernicus put forth a theory that stated a heliocentric model for the solar system. According to this heliocentric theory, all the planets, including Earth, orbit the Sun in circular orbits.

01:16Circular Orbits and Critical Velocity for Satellites
The Moon orbits around the Earth. In turn, the Earth (and other planets) orbit the Sun. The space directly above our atmosphere is filled with artificial satellites in orbit. One can examine the circular orbit, the simplest kind of orbit, to understand the relationship between the speed and the period of planets and satellites with respect to their positions and the bodies that they orbit.

01:29Kepler's Second Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. His first law states that all planets orbit the Sun in an elliptical orbit, with the Sun at one of the ellipse's foci. Therefore, the distance of a planet from the Sun varies throughout its revolution around the Sun.
While in an elliptical orbit, the total energy of the planet is conserved. Therefore, the planet slows down when it is at apogee and...

01:18Kepler's Third Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. In 1909, he formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe. However, in 1918, he published his third law of planetary motion, which gives a precise mathematical relationship between a planet's average distance from the Sun and the amount of time it takes to revolve around the Sun. It...
01:28Apparent Weight and the Earth's Rotation
Since all objects on the Earth's surface move through a circle every 24 hours, there must be a net centripetal force on each object, directed towards the center of that circle. The points of the north and south poles are the only exception to this rule.
For an object on the Earth's equator, the net centripetal force that accounts for its rotation is the Earth's pull towards its center, or the weight minus the normal force that prevents it from piercing into the Earth's surface. This force,...

01:16Gravitation
In the years before Newton, a general belief prevailed that different laws governed objects in the sky than objects on Earth. When Kepler wrote down the three laws of planetary motion, explaining in detail the geometrical properties of the planetary orbits around the Sun, there was no immediate idea to discern their connection with more fundamental laws. It was Isaac Newton who, in 1665–66, figured out the connection between planetary motion, the motion of the moon around the Earth, and the...
