That the Earth is round was known to ancient cultures but this knowledge was suppressed in Europe, mainly by the Catholic Church whose dogma insisted that Earth was the centre of the cosmos and lay under Heaven and above Hell. This is surprising since some of the best thinkers in Europe were clerics and monks within the Catholic Church.
Thales concluded that everything that exists ultimately comes from water. He believed that water was the fundamental substance from which all things originated.
The astronomer Copernicus publicly stated in the 1500s that Earth revolves around the Sun, contrary to the prevailing belief at the time that the Earth was the center of the universe. This heliocentric model laid the foundation for modern astronomy and challenged the geocentric view established by Ptolemy.
Johannes Kepler.
In 1838 Friedrich Bessel was able to measure the parallax of the nearby star 61 Cygni and thus determine its distance and independenly confirm the fact that the Earth orbits round the Sun.
Pythagoras stated the earth was round
Because during a lunar eclipse, Aristotle observed that the shape of the earth was round.
The Greek scientist who concluded that Earth was round was Pythagoras, around the 6th century BC. He based his conclusion on observations of the stars and their positions in the sky.
The Greek scientist who concluded that the Earth was round was Pythagoras, around the 6th century BC. His observations of the shape of the Earth influenced later scholars like Aristotle and Eratosthenes.
It is uncertain but variously ascribed to Pythagoras, Parmenides and Empedocles by their later promoters.
It always casts a curved shadow during a lunar eclipse
Aristotle observed that during a lunar eclipse, the shape of the Earth's shadow on the moon was curved. He reasoned that only a spherical object could cast a curved shadow, leading him to believe that the Earth was round. Additionally, Aristotle noted that as ships sail away from the shore, the hull disappears before the mast, suggesting the curvature of the Earth.
In the Dark Age of Science, it was believed that Earth was in the center of Solar System and all the planets including sun, revolve round the sun. This is called Geocentric Theory.Nicolas Copernicus, A Polish*Astronomer, proved that earth and other planets revolved round the sun. This is Heliocentric Theory.(Copernicus proposed the Heliocentric Theory in 1543, 64 years before the invention of telescope. I was all the work of his Mathematics.)_________________________________________________________________* Polish Astronomer is an Astronomer from Poland
Your mom. It was your mom who concluded it.
The ancient Greek philosopher Pythagoras is often credited with being one of the first to propose that the Earth was round in the 6th century BC. However, the idea of a spherical Earth was further popularized by the philosopher Plato and astronomer Aristotle.
Any early man that could use common sense would have figured that one out.
Greek mathematician and astronomer, Eratosthenes, is credited with determining that the Earth is spherical. In the 3rd century BCE, he calculated the Earth's circumference using the angle of the sun's rays at two different locations.
Thales concluded that everything that exists ultimately comes from water. He believed that water was the fundamental substance from which all things originated.
