Is it just a coincidence that the Earth's atmosphere refracts light just enough for the Nikon camera brigade to make their videos?
Has god done this just to piss scientists off?
Is it just coincidence that the supposed diameters of the "moon" and the "sun" and the supposed distances to them are such that during a total solar "eclipse" the former obscures the latter *exactly*?
The moon doesn't obscure the sun *exactly* during the vast majority of solar eclipses. Sometimes the moon appears too small and we see an annular eclipse. Other times the apparent size of the moon is larger than the sun and the total eclipse lasts for longer than a moment (the moon can appear to be up to 6.5% larger than the sun). The rare exception is two points along the path of of a hybrid eclipse where the eclipse changes from annular to total and from total back to annular. This occurs in the situation where the moon appears too small at the beginning and end of the eclipse track, but the spherical shape of the earth brings the surface close enough to the moon for its apparent size to exceed the apparent size of the sun.
The moon is currently receding from the earth by a few centimeters per year. In about half a billion years it will be too far away to ever produce a total solar eclipse again.
Yes, it's a coincidence that the sizes and distances work out to produce eclipses like we see, and it's a temporary situation at that. We just got lucky. Sometimes things work out that way.
