500 years ago, people knew the Earth was round through a combination of empirical observations and logical reasoning. Scholars like Pythagoras and Aristotle had proposed theories about the Earth's shape based on observations of the stars, changes in shadows, and the curvature of the horizon. Additionally, circumnavigation voyages by explorers like Ferdinand Magellan provided further evidence of the Earth's spherical shape.
In ancient times, people believed the Earth was flat. It wasn't until the 16th century when scientists like Copernicus and Galileo proposed the idea that the Earth was actually round. Later studies and discoveries confirmed the spherical shape of the Earth, as well as its layered structure with a solid inner core, liquid outer core, mantle, and crust.
No one believed that the earth was flat in the 1600 it was a well know fact that the world was round. This myth that people used to believe that the world was flat didn't exsist before 1870-1920. The myth probably came to existance because it was way more intriguing that Colombus in a world where everyone thought was flat was the only one who believed it was round.
If you mean how many years the earth can exist as we know it then we don't know. New inventions and stuff will change our lifestyle at any point from in the next week to the next century. If you mean how many years the earth will exist as far as we know then it will probably be a few more billion.
The Earth was formed about 4.57 billion years ago when a mass of particles and gases formed a rotating cloud that eventually concentrated into what we know call Earth.
It takes about 10 to 20 years for a simple piece of paper to decompose, while more complex items like plastic bottles can take hundreds of years. However, some materials may never fully decompose, creating long-lasting environmental hazards.
People have known the earth is round for over 2,000 years and did experiments. very is likely the Egyptians and Moses thought it was round. most people like flat earthers dont know people knew the earth was round before Columbus.
Yes earth is a spherical (round), thousands of years ago people did not know that planet earth was round, they just thought it was flat so if they went to far they would fall of the edge! but nowadays because of spacetravel etc, we have seen planet earth and they have noticed it was a spherical planet. So yes it is.
Have you ever heard any news about people falling off Earth's edge? yeah but that doesn't really answer the question.
There is no way to know.
Hard answer as the question could be read as when did people know that the earth is round, or how do people know that the earth is round. Historically, many people have been credited with the theory of spherical earth, dating back to ancient Greece. Many philosophers of Ancient Greece spoke of earth being round, but most often the credit is given to Pythagoras. The explanation that the world wasn't flat was by observing changes in altitude and the placement of the stars in different locations as they moved around the pole.
This had been known since the ancient Greeks. It is a fable that people didn't know this. Despite the fact we have seen earth from space there are people who think the earth is flat.
No, the earth is round as far as I know
some people don't know but some really smart people think that in a few years we will know how common or how rare earth sized planets are in the galaxy around us.scientists have found a worm rocky earth the planet is most earth like.
I know. Isn't that just the darndest thing.
