Now..finally can we know how do you know how far is the Sun?
Well, the distance between the sun and the earth can be calculated using orbital mechanics and trigonometry.
But I'm afraid that this involves the scientific method, which is ofcourse no match for your senses and impressions.
You see for the longest time man was convinced that the earth was at the center of the universe, which is understandable since it was the only
perspective they had. Everything in the sky looks small and insignificant, except for maybe the moon and the sun. They even have the same apparent
size in the sky so they must be roughly the same distance from the earth.
By that same logic you could argue that the earth is stationary and everthing else is moving. Because lets be honest, can you sense the earths
movement, or are you also under the impression that the earth is stationary?
So what do your senses tell you about the different stars in northern and southern night sky? Or the lunar eclips? Why do other bodies in our solar
system look like spheres, or are you under the impression that they are also a flat planes with a round circumference always in the proper orientation
when viewed from earth?
