The heliocentric theory proposed by Copernicus suggested that the Earth revolved around the sun, leading to a better understanding of the solar system's organization. Isaac newton's law of universal gravitation further explained the motions of celestial objects by stating that every object in the universe attracts every other object with a force proportional to their masses and inversely proportional to the square of the distance between them. These two theories together significantly advanced our understanding of the cosmos and how gravity influences celestial motions.

How did astronomy resolve the issue of the geocentric theory versus the heliocentric theory during the scientific revolution?
First there were several different theories put forward to explain the movements of the planets. The main ones are Ptolemy (geocentric) and then Copernicus (heliocentric). Both theories explained the positions of the planets within the accuracy of the observations that were made at the time (up to the 1580s). Both theories used combinations of circles to model the planets' orbits. Then Tycho Brahe came on the scene with much improved equipment for measuring the planets' positions with unprecedented accuracy. Although Tycho believed in the geocentric idea, his observations were used by Johannes Kepler to create a new heliocentric theory in which the planets move in elliptical orbits, published in 1609. At that time there was no way of knowing which theory was right, except that Kepler's theory fitted the observations best. By the end of the 1600s, scientists had made significant discoveries in dynamics, the science of moving objects, and in gravity. The laws of motion and the law of gravity were used by Isaac Newton to prove theoretically that a planet in the Sun's gravity field must move in an elliptical orbit. This achievement put Kepler's theory in the spotlight, where it has been ever since. Apart from tiny corrections from relativity, Kepler's heliocentric theory is the one still used today.
What year did Brahe and Kepler work together to defend the heliocentric theory?
Tycho Brahe was a nobleman and a difficult character, and it would have been beneath his dignity to 'work together' with Kepler, one of his employees. Most of Kepler's work was done after Brahe's death when he gained access to the figures from Brahe's detailed high-quality measurements. Kepler used the measurements and assumed the heliocentric idea - the Sun at the centre - to produce his three laws of planetary motion. Many years later Newton's discoveries of the laws of motion and the law of gravity, plus his use of differential calculus, showed why Kepler's laws are as they are, and the heliocentric theory was later generally accepted.
Isaac newton's theory of natural law?
Sir Isaac Newton is best known for having invented the calculus in the mid to late 1660s (most of a decade before Leibniz did so independently, and ultimately more influentially) and for having formulated the theory of universal gravity -
Did Galileo develop theory that what makes apples fall keeps planets in their orbits?
No. Galileo experimented with gravity and began developing the theory. But Sir Isaac Newton was the mathematician who proposed the inverse-square law of universal gravitation, which hypothesized that gravity is what keeps the planets in their orbs. He said that his theory was inspired by watching an apple fall from a tree.
What is Heliocentric Vs. geocentric theory?
The Difference is that a heliocentric model says that the sun is in the center but not the exact center and all the other planets and the moon orbit the sun. But a geocentric model states that the earth was in the center and that the sun moon and stars all went around earth. That is the difference.Heliocentric:Also, All the planets revolve around the sun.Stars are very much farther away than the Sun.Any motion of the stars is a result of the Earth's rotation.Any movement of the Sun is due to Earth's rotation and revolution about the sun.The heliocentric model were ellipses NOT circular orbits.Geocentric:Epicycles added to epicycles.Precision timing for Venus and Mercury.Earth placed "off" center.The Earth is located at the center of the universe and all the planets revolve around the Earth.
Does a scientific law become a scientific theory?
A theory, when proven over time, can become a law. Example: Law of Gravity and Theory of Evolution
Why is the law of gravity a scientific law- not a scientific theory?
In general, a scientific theory is a proposed explanation that has not been fully proven yet, while a law is a theory that has been proven to be true by lots of experimentation. The theory of Gravity has been tested and shown to be correct so much that it is at this point clearly a scientific law.
What is heilocentric theory?
The heliocentric idea is that the Sun is at the centre of the solar system and it replaced the alternative geocentric system (in which the Earth was at the centre) gradually from about 1680 to 1840 as more and more scientific showed that it was the best model. Finally when stellar parallax was discovered in 1838 by Bessel most astronomers were forced to accept the heliocentric theory, which includes Kepler's laws of planetary motion and Newton's law of gravity and the laws of motion.
What is the diffrence between scientific law and scientific theory?
A scientific law describes a consistent and universal relationship observed in nature, like the law of gravity. A scientific theory is a well-substantiated explanation of some aspect of the natural world based on evidence and reasoning, like the theory of evolution. Laws describe what happens, while theories explain why and how it happens.
What explanation does the theory of general relativity provide for gravity?
Gravity is a result of curved spacetime But apart from providing that abstract concept it does not provide any mechanism or explanation.
What did Galileo discover that gave support to the heliocentric theory?
The Jovian moons. Galileo had little evidence for the heliocentric theory, which was later (in the 18th century) generally accepted as correct after the laws of motion and the law of gravity showed that the Sun is by far the most massive object in the solar system and therefore must be at the centre. Galileo did not have the other major piece of evidence supporting the heliocentric theory, which is the parallax shown by relatively close stars as the Earth moves round its orbit. Parallax is extremely small and was impossible to observe in Galileo's time, and this was used to support the idea that the Earth is at the centre. Bessel made the first measurements of parallax in the 19th century.
Name the theory that describes gravity?
The theory that describes gravity is called "General Relativity," proposed by Albert Einstein in 1915. It states that gravity is a result of the curvature of spacetime caused by mass and energy.

Is gravity the second law of gravity?
Gravity is a fundamental force of nature that causes two objects to be attracted to each other based on their mass and distance. The second law of gravity does not exist; instead, there are various laws of physics that describe how gravity operates, such as Newton's law of universal gravitation and Einstein's theory of general relativity.
How does newtons law affect the force of gravity?
Newton's law of universal gravitation states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This law helps us understand how the force of gravity between objects changes as their masses change or as they move closer or farther apart.
What is the difference between the theory of gravity and the law of gravity?
Newton's law of Gravity involves matter creating forces that change motion and Einstein's Relativity involves matter "warping" space and changing motion.The Deflection of 1.7" seconds explained by Einstein as the result of curvature is better explained by Newton, where g is the earths gravity acceleration 9.8 m/s^2 and Rs= 150Gm distance to the sun and d the deflection due to the earth's gravity:Tan def = d/Rs = 1/2 gt^2/Rs= 1/2 9.8 (Rs/c)^2 /Rs = 1/2 9.8 Rs/c^2 = 8.166E-8 with arctangent =1.68".This indicates that Einstein's Relativity Theory of space curvature is defective or wrong.Newton and Einstein's Theory of Gravity are defective in leaving out the vector energy in their Gravity Theory. The correct Theory of Gravity involves quaternion energy that consists of scalar energy and vector energy E= -mu/r + mcV. The Quaternion Theory of Gravity confirms Newton's Universal Law as opposed to Einstein's space warping Theory.
What was significant about Newton's theory?
Isaac Newton's Law of Gravity was significant, in that he claimed his Theoiry of Gravity, applied to the apple falling from a tree, the moon falling and the earth falling around the sun. He claimed that his Theory applied throughout the universe! A Universal law of Physics.
