How can we prove that the Earth is round?
With enough fuel one day you guys shall reach at where you had started. This will prove that earth is round. Response to comments: All material objects apply the gravitational force on all other material objects. The earth is made up of atoms,molecules etc, all these constituent particles exert force on each other.
What is a level used to make?
A level is used to make something horizontal with the earth’s surface. This handy tool can also measure vertical plumb. Learn about levels here.
How does a level measure the level of the Earth?
With a bubble of air inside a vial of encased liquid, the level shows when its frame is exactly horizontal with the earth’s surface, called “level.” Longer levels typically have additional vials turned perpendicular so the tool can measure vertical “plumb.”
What does the a level indicate?
A level indicates the horizontal plane. With a bubble of air inside a vial of encased liquid, the level shows when its frame is exactly horizontal with the earth’s surface, called “level.” Longer levels typically have additional vials turned perpendicular so the tool can measure vertical “plumb.”
Since the earth is rotating (see the “ Foucault Pendulum ” experiment for a definite proof, if you are doubtful), the consistent oval-shadow it produces in each and every lunar eclipse proves that the earth is not only round but spherical—absolutely, utterly, beyond a shadow of a doubt not flat. 2. Ships and the horizon
Can gravity be used to prove the Earth is a globe?
Gravity is a theoretical concept conceived of within the globe earth model. It has no place in a flat earth model. Conclusion: Gravity has no relevance outside the globe earth model, it is not relevant to the flat earth model and can not be used to prove the earth is a globe. It is a concept born of the globe model.

How do we know that the Earth is a sphere?
OK, so how do we know — scientifically — that the Earth is a sphere? At a very basic level, we can see the Earth’s curvature through satellites that we’ve launched into space. Additionally, through the use of high-powered telescopes, we’ve been able to examine planets both in our solar system and beyond, and all of them are spherical in shape.
