Physics, Astronomy & Cosmology / Re: How can the moon's position look strangely tilted sometimes?
« on: 11/04/2014 16:36:46 »Ok well I'm not a scientist and I'm not gonna throw a bunch of equations etc up just to confuse people.The calculations I posted were not to "confuse people" but to show that this is normal and predictable.

But has the moon always done this or is it just been happening the last couple of years?Yes, it has always done this.

There are a lot of people who look up at the sky and just gaze at it. For decades I've been looking at the sky and moon. And I don't care about all your math equations and stuff.Math is the language of science. The moon looks like this primarily because of field rotation (lunar libration as shown by someone else in a video above is a secondary and smaller factor). The degree to which it looks tilted is completely predictable mathematically. It's simply the result of viewing the sky from the side of a rotating sphere (the earth).

Why is it that ever app or anything you see anywhere still shows the moon like what most are used to?Moon phase calendars cannot account for field rotation, they do not know where you are on earth or when you are observing other than the date, both of which must be known to properly calculate the apparent tilt. Some apps do ask for this information and do take it into account though, such as SkySafari, the app I use on my phone.

Has everyone forgot to update all their software for the change?See above. If this is some kind of "change" then why is it perfectly normal and predictable using a book that is decades old, long before there were ever "smart phones" to begin with?
