Important If True 25: The Fresno Experiment

Recommended Posts

I think I've got the best way to think about the Moon illusion.

Imagine a plane directly overhead.  Put your hand over your head at arm's length and pretend to measure the plane between your fingers.  Now imagine the plane flying to the horizon and keeping it framed between your fingers.  Your fingers will get closer together as it gets further away, right?

 

Now imagine the moon overhead.  Do the same thing, frame it between your fingers and imagine following it as it moves across the sky to the horizon.  It doesn't get any smaller!  So what's going on?  It must not be going away like the plane did.  It must be "closer" at the horizon.

 

Since we expect clouds or planes to look smaller at the horizon because they are further away, when the moon doesn't get smaller on the horizon it seems too big or too close.

 

Another way of thinking about it is that clouds and birds and planes in the sky are on a hemisphere the center of which is far below us at the center of the earth.  Looking straight up we are right up against the edge of the circle and things at the horizon are far away.  But the hemisphere of the moon and the stars is so far away we're basically at the center of the hemisphere and things at the horizon are essentially the same distance as things overhead.  But if our brains imagine the moon and stars on the same hemisphere as the clouds, everything at the horizon ought to be much farther away and therefore smaller.  But it's not smaller, so it seems either too big or too close.

I renounce science moon and embrace Big Moon. Consider this: Scientists say that the sun is 64 million times larger than the moon, and yet on Sunday, the moon will be so large that it covers up the sun.

Ugh this is so true, just think about it

I've received some unexpected pushback about this theory from my friends and family, and let me just nip some counterarguments in the bud.

 

1. The sun is further away so it will appear smaller. Actually, our binocular vision can only perceive depth up to 200 meters away. So clearly anything beyond that will not appear any smaller.

2. The eclipse is on Monday, not Sunday. Where did you get that information? A scientist? I think we've already proven who we can and can't trust in this matter.

Big moon is actually just the sun. Evidence:

  • The Sun is bright. So is the moon. So is big moon. Therefor they are all the same category of objects.
  • I've never seen big moon and the sun in the same place.

Big moon is just when the sun calms down a bit and takes a break from all the shining. Classic case of mistaken identity.

This is my favourite moonspiracy theory. Finkel is Einhorn!
