Viking Project tests general relativity, November 25, 1976
The Viking spacecraft arrived at Mars in the summer of 1976 and passed through superior conjunction on November 25, as Mars passed directly behind the Sun as seen from Earth. This provided researchers the opportunity to use the spacecraft in an experiment to test general relativity.

After completing the primary missions, the Viking continuation mission objectives included a radio science solar conjunction relativity experiment. Scientists began an experiment that used the landers and orbiters as transponders, sending radio signals to the lander on Mars and instructing the lander to the return signals. The round-trip travel times of the radio signals going from Earth to the Viking landers and orbiters were measured.
Using dual-band, one-way ranging allowed estimation of the contribution of the solar-corona plasma to the echo delays obtained from ranging to the spacecraft.
The data confirmed the Shapiro time delay effect, which states that radar signals passing near a massive object take slightly longer to travel to a target and longer to return than they would if the mass of the object were not present.
 A report, “Viking relativity experiment: verification of signal retardation by solar gravity” published in 1979 by researchers at MIT and the Jet Propulsion Laboratory, analyzed 14 months of data obtained from radio ranging to Viking to verify the prediction of the general theory of relativity.
Published by Albert Einstein in 1916, the general theory of relativity predicted that the round-trip or echo delays of light signals traveling between the Earth and Mars would be increased by the direct effect of solar gravity. The theory included gravitational time dilation, where time passes differently in regions of different gravitational potential.
NASA has continued to test general relativity, most recently with the Cassini space probe (see a NASA artist rending of its testing at right) and Gravity Probe B, which also confirmed the theory.

NOVEMBER 09, 1919
NEW YORK TIMES, November 9, 1919
* Very early Albert Einstein
* Theory of Relativity proved
Page 6 begins with an article which, in scientific circles, is definitive proof of Einstein's theory of relativity.
As background, in 1916 Albert Einstein published his general theory of relativity in full mathematical detail. That opened the window on a radically new framework for physics, abolishing established notions of space and time and replacing Newton’s formulation of the laws of gravity. Einstein’s revolution was to change the course of science; but in the years immediately after publication, there was no definitive observational evidence that his theory was correct.
But an eclipse in 1919 gave opportunity to prove it. By harnessing a total solar eclipse scientists argued that the bending of light by the sun’s gravity could be measured. This was a critical test, because Einstein’s theory predicted a deflection precisely twice the value obtained using Isaac Newton’s law of universal gravitation. The observations proved Einstein's theory correct.
The column heads on page 6: "ECLIPSE SHOWED GRAVITY VARIATION" "Diversion of Light Rays Accepted as Affecting Newton's Principles" "Hailed As Epochmaking" "British Scientist Calls the Discovery One of the Greatest of Human Achievements". The photos show the full text of the article.
Complete 1st section only with 24 pages, light toning and a little wear at the margins, irregular along the spine, generally good. Should be handled with care.

Modo IA Todo Imágenes Vídeos Noticias Maps Shopping Libros Vuelos Finance The connection between Mercury, Albert Einstein's Relativity, the May 29, 1919 experiment, Venice, and capitalism weaves a fascinating historical narrative that bridges astrophysics, deep etymology, and economic history. Here is the comprehensive breakdown of how these concepts interconnect. 1. Mercury and Einstein's Theory of General Relativity The planet Mercury provided the very first empirical proof for Einstein's Theory of General Relativity. The Newtonian Failure: Under Isaac Newton's laws of gravity, planets orbit the Sun in fixed ellipses. However, astronomers noticed that Mercury’s orbit was slowly rotating in space over time—a phenomenon called perihelion precession. Newton's equations could account for most of this movement due to the pull of other planets, but left an unexplained anomaly of 43 arcseconds per century. Scientists even invented a hypothetical hidden planet named Vulcan to explain the discrepancy. Medium ·Ethan Siegel The Einsteinian Triumph: In 1915, Einstein applied his new math. He realized that gravity is not an invisible pulling force, but rather the bending of spacetime caused by massive objects. Because Mercury is the closest planet to the immense mass of the Sun, it travels through deeply warped spacetime. Einstein's equations perfectly predicted the extra 43 arcseconds of precession without any adjustments, proving his theory accurate. 2. The Solar Eclipse Experiment of May 29, 1919 While Mercury's orbit was a retrospective calculation, Einstein needed a proactive, real-world experiment to convince the global scientific community. This happened during the total solar eclipse of May 29, 1919. royalsocietypublishing.org +2 The Relative Concept of Time and Space: General Relativity dictates that heavy masses warp both space and time. If space is truly warped around the Sun, starlight traveling past it should bend. Wikipedia +3 The Experiment: British astronomer Sir Arthur Eddington led expeditions to Sobral, Brazil, and Príncipe, West Africa, to photograph stars during total darkness. Because the Sun was blocked by the Moon, they could capture the background stars. The Result: The apparent position of the stars had shifted exactly by the margin Einstein predicted ( ). This proved that the Sun's mass literally warped the path of light and altered the fabric of spacetime, catapulting Einstein into instant global fame. 3. The Star of David, the Israel Flag, and the "Cycle of Mercury" The connection here transitions from literal astrophysics to historical symbolism and geometry: Geometrical Synchronization: The Star of David (the emblem on the national flag of Israel) is a hexagram formed by two overlapping equilateral triangles. In historical astrology and early astronomy, complex planetary alignments over long synodic periods—specifically the retrogradations and synodic cycles of Mercury relative to Earth—were sometimes mapped geometrically. Over specific multi-year cycles, Mercury's visual alignment points against the zodiac backdrop roughly approximate a six-pointed geometric matrix. The Einstein Connection: Albert Einstein was a prominent secular Jew who strongly supported the establishment of the Hebrew University of Jerusalem. Later in his life, following the death of Israel's first president, Chaim Weizmann, in 1952, Einstein was formally offered the Presidency of Israel. He gently declined the offer, stating he lacked the natural aptitude and interpersonal skills to deal properly with people and official functions. 4. Venice, Piazza San Marco, and the Etymology of Commerce Moving from the sky to the shores of Italy, the concept of Mercury transforms from a planet into its mythological root: the Roman god Mercury (Hermes in Greek myth), the patron god of financial gain, commerce, and travelers. [ Latin: Merx (Merchandise) ] │ ├───► God Mercury (Patron of Trade) ───► Planet Mercury │ └───► Mercari (To Trade) ───► Mercato (Market) ───► Mercantilismo The Etymology of Capital: The root word for market (mercato), merchant (mercante), mercantilism, and commerce all derive from the Latin word merx (merchandise) and mercari (to trade). The god Mercury embodies this linguistic root. Piazza San Marco and Venetia: The Republic of Venice was the historical epicenter of early global trade, modern banking, and maritime capitalism. Piazza San Marco served as the state heart where international wealth accumulated. Statues and iconography of Mercury can be found decorated across Venetian architecture (such as the Loggetta at the base of the St. Mark's Campanile) celebrating the city's commercial power. 5. Mercantilism, Capitalism, and the Rivers of Venice Venice is inherently tied to water, which served as the physical highway for its wealth. The Venetia Water System: Built upon a muddy lagoon, Venice did not rely on traditional rivers, but rather on its saltwater channels (like the Grand Canal) and its proximity to northern Italian rivers like the Po and the Adige. These waterways connected the heart of Europe to the Mediterranean Sea. The Alchemy of Mercantilism: Venice pioneered early mercantilism—an economic system where a state aggressively manages its trade balances to hoard precious bullion (gold and silver). The Venetian state built the Arsenal, a massive state-enforced shipyard, to secure naval dominance and protect merchant profits. The Fluidity of Capital: Just as the liquid element mercury flows quickly and is difficult to pin down, Venetian financial systems introduced "fluid" capital. They invented double-entry bookkeeping, advanced credit markets, government bonds, and joint-venture contracts called the Colleganza. This fluid movement of maritime wealth via the canals of Venice laid the direct institutional groundwork for modern global capitalism. If you would like to explore any of these specific areas further, let me know!

Modo IA Todo Imágenes Vídeos Noticias Maps Shopping Libros Vuelos Finance Sí, existe una relación histórica, profunda y fascinante entre las teorías de Albert Einstein y el mercurio, manifestada de dos maneras completamente diferentes: una en el planeta Mercurio (vía Relatividad General) y otra en el elemento químico mercurio (vía Relatividad Especial). 1. El Planeta Mercurio y la Relatividad General (Astronomía) La órbita del planeta Mercurio fue la primera prueba empírica y el gran triunfo que consolidó la Teoría de la Relatividad General de Einstein en 1915. Wikipedia +1 El misterio astronómico: Durante el siglo XIX, los astrónomos notaron que la órbita elíptica de Mercurio giraba lentamente en el espacio (un fenómeno llamado precesión del perihelio). La gravedad de Newton podía explicar la mayor parte de este movimiento debido a la atracción de los otros planetas, pero quedaba un desfase inexplicable de 43 segundos de arco por siglo. YouTube +3 La solución de Einstein: Al estar tan cerca de la enorme masa del Sol, Mercurio se desplaza por un espacio-tiempo profundamente curvado. Cuando Einstein aplicó las ecuaciones de su Relatividad General a la órbita del planeta, el término relativista predijo con exactitud matemática esos 43 segundos de arco sobrantes sin necesidad de alterar ninguna otra constante. Al ver que su teoría resolvía este enigma de décadas, Einstein experimentó tal nivel de emoción que, según sus propias palabras, tuvo palpitaciones cardíacas. revista.ilce.edu.mx +3 2. El Elemento Mercurio y la Relatividad Especial (Química) La física relativista también explica por qué el mercurio ( , número atómico 80) es el único metal líquido a temperatura ambiente, un fenómeno gobernado por la Relatividad Especial. Efectos en los electrones: El núcleo del átomo de mercurio tiene 80 protones, lo que ejerce una atracción eléctrica descomunal sobre sus electrones internos (el orbital ). Para no caer hacia el núcleo, estos electrones deben moverse a velocidades extremas: aproximadamente el 58% de la velocidad de la luz. Scientific American Aumento de masa y contracción: De acuerdo con la Relatividad Especial, cuando un objeto se acerca a la velocidad de la luz, su masa relativista aumenta. En el mercurio, los electrones incrementan su masa alrededor de un 23%. Esto hace que sus órbitas se contraigan y se vuelvan mucho más estables y cercanas al núcleo. Scientific American +1 Por qué es líquido: Esta contracción se transfiere en cadena hasta los electrones de valencia más externos (orbital ). Como estos electrones están tan fuertemente atraídos y "retenidos" hacia el núcleo, los átomos de mercurio son incapaces de compartir electrones eficientemente con otros átomos de mercurio vecinos. Al no poder formar enlaces metálicos fuertes entre sí, no logran crear una red cristalina sólida a temperatura ambiente y se comportan como un fluido. Resumen de Conexiones Sujeto Teoría Relacionada Efecto Físico Planeta Mercurio Relatividad General (1915) Explicación del avance anómalo de su perihelio (43 segundos de arco/siglo) debido a la curvatura del espacio-tiempo cerca del Sol. Elemento Mercurio ( ) Relatividad Especial (1905) Aumento de masa en sus electrones veloces, compactando el átomo e impidiendo enlaces fuertes, lo que lo vuelve líquido.
