Is it possible for gravity to be a vacuum?

[LoneWolf]

As matter attracts other matter through electromagnetism and as that combined matter within a per unit volume becomes more dense, as it is compressed into a smaller per unit volume, a portion of the original per unit volume will be left matter-less, thus in theory creating a vacuum. So is gravity actually a suction created because of this vacuum?

No.

Because a vacuum doesn't do anything in a vacuum.

Gravity works without air; a vacuum doesn't.

[LoneWolf]

So as the matter attracts and compresses leaving a mass-less area of lower pressure and density wouldnt this area attempt to balance out with the area outside of its outer circumference. If the area around it was equal in pessure and density or becomes equal then these conditions would remain constant but as this area encounters other areas of higher pressure and density the areas would try to balance out but as the areas are balancing, matter would naturally be forced into the electromagnetic grasp of the other mass thus creating a cycle until all is balanced again. Right?

I'm not sure what you're trying to describe, but gravity doesn't work that way. There is no cycle of balancing involved - one of three things will happen:

 

1. The lower mass object will fall into the larger mass, and eventualy collide.

2. The lower mass object will orbit the larger mass.

3. The lower mass will escape from the gravity of the higher mass.

 

Note that the last two options require the lower mass object to have sufficient enegy in their motion to acheive the result specified.
