This scene, captured with a 35mm camera from inside the Space Shuttle Endeavour, shows Jupiter rising above the airglow over Earth’s horizon. The crescent Moon is at top frame.

Explain why earth can’t be flat Thx

Explain why earth can’t be flat Thx

This is a simple and solved case. The problem is that there are people who want to draw attention to themselves, and end up inventing these things.

There are several earth images taken from space to prove this.

The possibility of the spherical earth was already predicted by ancient Greek philosophers, such as Pythagoras and Aristotle.

They cited simple observations, such as the changing position of stars as you travel north or south, the sinking of ships below the horizon, and the shape of the moon.  

Despite this, there is other evidence that proves that the earth is not flat, like the lunar eclipse.

image

You can see the shadow of the Earth crossing the face of the Moon, and the shape of the shadow is curved because the Earth is spherical.

We can also mention the existence of time zones and several other aspects that prove that the earth is spherical. I do not think I need to put them all here.

Despite all this, look at the other planets (the largest moons, stars, etc.) all are round. This is because of the force of gravity.

image

I will use our solar system as an example. When our Solar System was forming, gravity gathered billions of pieces of gas and dust into clumps which grew larger and larger to become the planets. The gravity of a planet pulls equally from all sides. Gravity pulls from the center to the edges like the spokes of a bicycle wheel. This makes the general shape of a planet a sphere, which is a three-dimensional circle.

image

Other celestial bodies, comets and asteroids have irregular shapes because they do not have enough mass for gravity to mold them and leave them round. 

So there is no reason why the force of gravity works for all other planets and does not work for our planet, leaving it flat. (more)

We really do need to figure out a solution to the space junk problem before it gets out of hand. Fortunately, SpaceX is on it!

A view of the Apollo 11 lunar module “Eagle” as it returned from the surface of the Moon to dock with the command module “Columbia”. A smooth mare area is visible on the Moon below and a half-illuminated Earth hangs over the horizon. The lunar module ascent stage was about 4 meters across. Command module pilot Michael Collins took this picture just before docking at 21:34:00 UT (5:34 p.m. EDT) 21 July 1969. (Apollo 11, AS11-44-6642)
