Proof Earth is sphere and not a flat surface.
if we look at the moon it has a curvature when the sunlight reflects from it and this curvature only take place if the reflector is a sphere, if it is flat all of it will be illuminated or all of it will be dark.
if we look at the pictures of Earth it has same curvature because it is a sphere if it was flat it will be either all reflector or all dark.
Bearing in mind that curvature on Earth happens every 24 hour while the curvature on the moon happens every 29 days so the flat Earth theory they provide cannot solve this problem.
This is proof that Earth is not a flat surface.
Flat earth people say, Earth has a dome, also called a “firmament,”
In this picture we don't see the Dome so either it is transparent or there is no Dome it says the Indian satellite took the picture from the moon.
We know Indian satellite landed on the dark side of the moon, I wonder how they took this picture since earth is invisible, from the dark side of the moon.
therefore the picture is a fake picture.
If planet Earth is flat it must have a dome therefore the air density from top to bottom must have the same value.
But in reality we have now the density of the air changes dramatically on a different heights below see the different densities at different heights therefore the flat earth is wrong and planet esrth is a sphere.
At the sea level air density
1.293 kg/m³
At 100 km,
Height air density is roughly 13 micro gram/m³.
at 200 km Height air density 0.1 micro gram/m³
at 300 km Height air density 0.0001 mico gram/m³
Air density decreases significantly as altitude increases. Here's a general idea of what air density might look like at those heights ¹:
- *100 km Height*: At this altitude, we're in the thermosphere, where air density is extremely low. While I couldn't find exact values for 100 km, at around 80-90 km, air density is roughly 1.3-4.5 x 10^-5 kg/m³. Let's estimate it to be around 1 x 10^-5 kg/m³ or less at 100 km.
- *200 km Height*: At this altitude, air density is even lower, typically around 1 x 10^-7 kg/m³ or less. The exact value can vary depending on solar activity and atmospheric conditions.
- *300 km Height*: Here, air density is extremely thin, roughly around 1 x 10^-10 kg/m³ or less. This is near the edge of the Earth's atmosphere, where it transitions into outer space.
Keep in mind that these values are estimates and can fluctuate based on various factors, including solar activity, atmospheric conditions, and the time of day. For precise calculations, we'd need more specific data on temperature, pressure, and composition at those altitudes ².
What is the density of air at 400 km?
For example, a typical orbital altitude of the Space Shuttle is 400 km above the Earth's surface. At that height, the air molecules are about 16 km apart from each other. The average distance between molecules is called the mean-free path. At that 400 km altitude, the air density is only about 3 x 10-12 kg/m3.Jan 25, 2024
At room temperature, the average speed of air molecules is around 500 meters per second (m/s), or roughly 1,100 miles per hour.
