First of all how do you know that it is?
Newton's ring is a ring within a ring within a ring. It is a question of resolution so get a bigger looking glass to see some rings within the ring that seems like a dark circle.
Well actually the dark center is caused by interference or the place where waves cancel each other.

The rings are formed by intereference between the direct and the reflected light. At point of contact there is no reflection. Thus light is transmiited without reflecting.
If you'll see the Newton's rings in transmitted light... you'll see a bright center.

Becouse in Newton's rings there are two types of interference occurs:
1) Constructive interference:
occurs when the waves of light are in phase (the crest of 1st wave on the crest of 2nd wave & the trough of the 1st wave on the trough of the 2nd wave) so they renforce each other so we can see bright rigion
2) Distructive interference:
occurs when the waves of light are NOT in phase (the crest of 1st wave NOT on the crest of 2nd wave & the trough of 1st wave NOT on the trough of the 2nd wave) so they cancels each other so we can see dark rigion =====> That is why you see the center of the ring dark

because it has so much gravity that even light cannot escape it. like a black hole
