What did Galileo discover?
Galileo's discoveries about the Moon, Jupiter's moons, Venus, and sunspots supported the idea that the Sun - not the Earth - was the center of the Universe, as was commonly believed at the time. Galileo's work laid the foundation for today's modern space probes and telescopes.
Galileo's Accomplishments in Astronomy
While in Padua, Galileo publicly argued against Aristotle's view of astronomy and natural philosophy. At Padua, Galileo began a long‐term relationship with Maria Gamba; however they never married. In 1600 their first child Virginia was born, followed by a second daughter, Livia, in the following year.
Galileo's conclusion from this thought experiment was that no force is needed to keep an object moving with constant velocity. Newton took this as his first law of motion.

Galileo Galilei discovered new worlds with his telescope.
10 Major Accomplishments of Galileo Galilei
His many discoveries include the law of inertia later used by Isaac Newton as the first law of motion, the parabola as the path of a projectile, the relationships between distance and velocity and between distance and time and at the continuity of acceleration.
Galileo invented the geometric and military compass, his first commercial scientific instrument, in 1597. The device, which resembled two rulers that moved over a third, curved piece, acted as an early calculator. Merchants could use it to work out monetary exchange rates.
What did Galileo discover?
Galileo's Law of Inertia states that; if no net force acts on an object, the object maintains in the same state of motion. This is a restatement of Newton's First Law of Motion. The first law of Motion is also known as Galileo's law of inertia.
Galileo, using an Archimedean model of floating bodies, and later the balance, argues that there is only one principle of motion—heaviness. Bodies move upward not because they have a natural lightness, he says, but because they are displaced or extruded by other heavier bodies moving downward.
In the early 17th century, Galileo Galilei found that all objects tend to accelerate equally in free fall. In 1632, he put forth the basic principle of relativity.
Experiments in Motion
The law of falling bodies is one of Galileo's key contributions to physics. It states that objects fall at the same speed regardless of weight or shape. Through his experiments, Galileo countered the pervasive Aristotelian view, which held that heavier objects fall faster than lighter objects.
Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are together the two pillars of modern physics.
Galileo measured that all bodies accelerate at the same rate regardless of their size or mass. Key among his investigations are: developed the concept of motion in terms of velocity (speed and direction) through the use of inclined planes. developed the idea of force, as a cause for motion.
The Galilean compass—not to be confused with drawing compasses—is a sophisticated and versatile calculating instrument for performing a wide variety of geometrical and arithmetical operations, making use of the proportionality between the corresponding sides of two similar triangles.
Italian astronomer Galileo Galilei provided a number of scientific insights that laid the foundation for future scientists. His investigation of the laws of motion and improvements on the telescope helped further the understanding of the world and universe around him.
