In the Kabbalah, the creation of the universe is spoken of as aTzimtzum, a contraction. Before this Tzimtzum, there was only the Infinite Light of God, which is totally incomprehensible and of which we can say nothing. We can only speak about what happens from the moment God’s Infinite Light is contracted and diminished into something that we can grasp – something that is on our finite level of existence. In the Kabbalah, creation is seen as residing ‘within’ God’s Infinite Light. The Midrash therefore says that God is the ‘place’ of the universe; the universe is not the place of God.
According to modern science, there is also a moment of creation. This is called ‘the Big Bang’. It denotes the beginning of time and space almost 14 billion years ago. Physicists can describe the nature of the physical universe from a fraction of a second after the Big Bang, but the moment of the Big Bang itself is spoken of as a ‘singularity’ – where no laws of physics apply. http://www.kosmic-kabbalah.com/big-bang
