    Here's the remarkable coincidence that allows us to see total solar eclipses: the diameter of the Moon is 400 times smaller than the diameter of the Sun, but it is also 400 times closer to us.pic.twitter.com/0KpbZMiHq1

        I have also found it remarkable that the moon rotates on it axis once every 27 days and rotates around the Earth once every 27 days with this synchronous rotation providing Earthlings the same view of the lunar surface...

        Just a very uninformed guess, but is it more likely to happen, as the moon's rotation is affected by the earth's rotation somehow? Meaning, with enough millions of years, they synchronise?

        There is no such thing as coincidence.

        And those kind of mathematically exact coincidences makes me sure that we are living in a virtual reality simulation aka Matrix of some sort. Reality is just too mathematical...

        What’s more remarkable is that the moon is slowly receding from earth and eventually in 620 million years total eclipses will no longer occur.

        You can also make a "perfect" total solar eclipses by holding a 1cent of € (radius= 0.008 m) at something more than a arm's length (1.8 m) from your eye. 1 penny (1 cent of $) has a little larger radius (0.0095 m) and should be kept at 2.1m (if I made the calcs right 🙄).

        You’re right, but the centre of that two-body system is inside the earth. A better example is Pluto-Charon, where both bodies move about a common centre of gravity

        What a coincidence isnt it? And that is just happening in a constant moving and expanding universe - how is that even possible?
