How hard we do that would be the intensity of the light. And the plane that we're oscillating, the jump rope or whatever, that's the plane of polarization. These little needles of cosmic dust from the exploded innards of a star that died in our galaxy many years ago and many, many billions of these stars, they produce these particles of dust.

So we saw that pattern instead of seeing the birth pangs of the Big Bang, the origin of the universe.

So the moon is always half a degree wide, same exact apparent angular diameter as the sun, which is unique among the 290 moons in our solar system. Only our moon has the same apparent diameter as seen from its planet as the sun does, meaning we're the only planet that can have a total solar eclipse. an exact total solar eclipse like we had a couple of months ago in Austin, Texas.

Be that as it may, the moon doesn't change its size. I would hope not.

The moon is about 60 times the Earth's radius from the Earth. It's 250,000 miles away, which is about one and a half light seconds away. and it is about the size of the continental U.S. in diameter, or a little bit less. So the moon's size doesn't change, but when the human eye has something to compare it to, the brain has a reference point to compare it to.

And because it's so big, if there's something in front of it, a 747, a person, a large building even, when you were, if the moon is behind that object, because it's so far away, moving even the Earth's entire radius doesn't change the moon's apparent angular diameter. It's the same in Peking as it is here, Beijing as it is in Los Angeles, right?

So that means a very small, a very large change in the distance in the Earth would change the building size dramatically, could reduce it to zero basically. But when you compare it to something that's close on the horizon, your brain has something visually to compare it to. When it's overhead, zenith or whatever, It doesn't have anything to compare it to, so you're just looking at it.
