GOD

You say Who is God or What is God?

But God can be neither who or what.

God is not only a creator but also a destroyer. God is extreme power or the initial energy that created universe and that would destroy it too.

Universe!

It is not something created by chance. It required some power or force to start events that lead to current scenario. The driving power behind all these events is we call GOD. Everything is driven by energy.

God is existing before anything can exist and would exist when nothing can exist.
God is neither existing nor inexistent.

God was there before any shape or form of matter was created so what can be the shape or form of God.
Energy has no shape nor any form.

He is the one that is sought to reside as an extreme power in black hole or we can say he is the source of energy to black hole even.

He is the energy that has woven the fabric of time and space. He has put us at specific position in this fabric to perform a special task. 

This fabric is not even delicate but also almost impossible to play with. To alter this fabric require ultimate energy which is impossible without God's help.
That energy can be taken from black hole, but this task would itself require great source of energy which is no where on earth.

As said this fabric is very delicate. If played upon with, it can be completely destroyed.
Time travel is kind of playing with this fabric, any attempt to alter it can lead to feedbacks which may torn it apart.
Even we have our future paths defined in this fabric and we will go only according to it. These defined paths would not let us go around and find a path to alteration.

You might be questioning if universe is created by God, then where did God created it? We have been studying from our childhood that big bang took place and our universe is expanding. But question is where did that big bang took place and in what universe is expanding? Our universe created in some universe and that created in other one and so on...!

This is a feedback question which is difficult or maybe impossible to answer. Going beyond the thing in which our matter and time is bound to impossible as matter. Matter is created by big bang and going beyond matter, what would be left without matter?

SO GOD exists in us all. We all are part of GOD.
