Blind Corner
1. Blind Corner of The Car
If we are driving a car and there is a motorbike driving through the back and overtaking up (Pic 1)
Even if we look at both the side mirror and the rear mirror, we may not see when it is behind (Black Arrow).
But we will see when it overtakes (Red Arrow).
2. Obscure Corner of The Universe.
Let's say that if the green square is a spotlight (Pic 2). If we turn on the spotlight at night, we will see aura or radius of The light (Green Arrow).
But if opened during the day, we will not see the radius (Pic 3) because of the blocked or swallow from sun's lights.
From Pic 4, let's say that there is no sun and the green square is a planet that has light's reflects. When we are looking from our earth....we will see a green light reflected (Green Arrow).
But if we are looking at it when the sun is shining brightly (Pic 5)....we will not see the light's reflects of the green square.
