So you have a question about lunar phases.
00:05
So below your question here, i've drawn out a little diagram.
00:09
I've got the sun over here and the earth over here.
00:12
Obviously not to scale.
00:14
Some would be really far away to the right and a lot larger than the earth.
00:19
But just to keep everything on the same page, i've got this little model here.
00:25
So i'm going to show, i have different places for where the moon would be in orbit around the earth.
00:32
So what we're doing is we're looking down above the, from above the solar system.
00:39
So the earth is sitting here and we've got the moon that's got, we're taking different pictures of where the moon might be depending on its orbit during the month.
00:50
So what's going to happen is as the sun shines, it's going to cause a shadow of the form.
00:56
And what we see is the light being reflected from the sun on the moon.
00:59
And if it's a full moon, it should be looking like this to us.
01:05
Let me get some yellow here.
01:06
So it should be a full moon should look like this to us.
01:10
Now, no matter where we're at or where the moon is on any given day, notice that the sun itself is causing the same pattern form.
01:24
So no matter where we're at, we're getting this same half of the moon is bright and half is in shape.
01:32
Shadow.
01:34
But from our perspective, we're not seeing that half and half like we are if i'm standing up way above the solar system, looking down at planet earth...
