How big would a lever have to be to move the earth?
The mass of Earth is 6×1024kg. If Archimedes can lift 60 kg, he would need a lever with an arm ratio of 1023:1. So if the short arm is one meter long, the lever length will be 1023 meters plus one.
What did Archimedes mean when he said give me a lever long enough and a fulcrum on which to place it and I shall move the world?
If you’ve studied any physics, then you know Archimedes is talking about the concept of leverage, which essentially means that through the proper use of tools you can do a lot more than you could through straight brute force methods.
Do you think that Archimedes could actually have moved earth with a lever if he’d had a place to stand in space?
You Can Move The Earth Archimedes did not realize it because he did not have the benefits of Newton’s Universal Law of Gravitation, but if he had, he would have realized that you could move the Earth just by jumping up and down, no levers needed.

Are you heavier in space?
In space without gravity pulling down on them, Astronauts are essentially weightless. It is important to explore the difference between mass and weight. While Astronauts may not weigh anything in space and can float around freely, their body shape and size does not change.
What did Archimedes discover?
Archimedes found that the volume of a sphere is two-thirds the volume of a cylinder that encloses it. He also discovered a law of buoyancy, Archimedes’ principle, that says a body in a fluid is acted on by an upward force equal to the weight of the fluid that the body displaces.
Who created the lever?
Lever – Invented by Archimedes The lever was first described in 260 B.C.E. by Archimedes(c. 287-212 B.C.E.),but probably came in to play in prehistoric times. A lever can be used to raise a weight or overcome resistance.it consists of a bar,pivoted bat a fixed point known as the fulcrum.
What was Nicolaus Copernicus famous quote?
“To know that we know what we know, and to know that we do not know what we do not know, that is true knowledge.”
What is Archimedes most famous for?
Archimedes was well known for his inventions and scientific discoveries. The most famous of these were the Archimedes’ Screw (a device for raising water that is still used in crop irrigation and sewage treatment plants today) and Archimedes’ principle of buoyancy.
Can astronauts be fat?
Is there also a height limit? You never see a fat astronaut. Because other requirements tend to exclude overweight people or people meeting those requirements by default wouldn’t have weight issues.
