Moon Quote by Max Tegmark
““Please hold your hand up at arm’s length and check which things around you can be blocked from view by your pinkie. Your little finger covers an angle of about one degree, which is about double what you need to cover the Moon—make sure to check this for yourself the next time you do some lunar observing. For an object to cover half a degree, its distance from you needs to be about 115 times its size,””

Your pinkie subtends about one degree, roughly twice the angular size of the Moon, illustrating how small objects can block celestial bodies when close enough.
In simple terms: A pinkie can cover the Moon’s size from a short distance.

So there came a time when George [Harrison] and I said 'Listen, when they ask next time, we're going to say we don't like that war and we think they should get right out.'
