Behold, the kingdom of God is in the midst of you.” — Luke 17:21b, NIV.
M-theory is the magic of Quantum Mechanics that manifests the objective reality of God’s Kingdom for all to see. Without it, all things will cease to exist.
For starters, M-theory is a theory of physics that unifies all consistent versions of the superstring theory. Some call it the “Membrane” theory, others call it the “magic” theory. Whatever the case, physicists agree that the true definition of what “M” stands for should be decided when a more fundamental formulation of the theory is known. 
M-theory is an extension of the string theory that posits that point-like particles are replaced by one-dimensional objects called “strings”. These strings can vibrate at different mode; each mode representing a different particle. There are 5 different modes of string theories (11A, 11B, HET-E, HET-O, and Type 1) . For quantum mechanic consistency, these string theories need to exist in 10 dimensions (9 different spatial dimensions + 1 time dimension). However, M-theory is an extension of these string theories that unifies them all. It comprises of supergravity that exists in the 11th dimension. It contains 2 dimensional-extended objects and 5-dimensional extended objects typically referred to as “branes” or “(mem)branes”.
Some scientists theorize that these branes are infinitely long and only a short distance across. Some scientists speculate that this membrane, at its maximum width, is only a trillionth of a millimeter (or 10^-20 mmm). In other words, this membrane in M-theory exists only a trillionth of a millimeter from every conceivable point in our 3-Dimensional world. Think about it as the world is being wrapped in this mystical membrane that is closer to your skin than your clothes. It exists everywhere – even on our bodies – though we cannot see it.
Now, when we consider the theory behind the mysterious membrane, does it resonate with you that this is exactly how the Kingdom of God is? Does it occur to you that when we pray the Lord’s prayer saying, “Your kingdom come, your will be done, on earth as it is in heaven.”, you’re testifying that this Kingdom of God exists on earth as it is in heaven. And in this Kingdom, everything that is the will of God will be done on earth (in our observable universe) as it is in heaven (the realm of the unseen).
If one is familiar with parallel universes , one will know that for every action done in the observable universe, there will be a larger implication that one cannot conceive . These larger-than-life implications transcend space-time and will affect our being in a trans-physical state.
Doesn’t this resonate so clearly with Jesus’ teachings when He said, “Truly, I say to you, whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven” (Matthew 18:18, NIV)? Now, if one binds someone on earth and that same someone is hence bound in heaven, that meant that for every matter that exists on earth, there will be an equal existence in heaven. Now, if we consider the parallels between the M-theory and the teachings of Christ, and presume that the membrane that M-theory refers to is the Kingdom of God in its unfathomable nature, then we will be a step closer to recognizing the sovereign unimaginable vastness of God’s created-heaven.
Of course, I’m not saying that there is an exact resemblance between the membranes of M-theory and God’s Kingdom on earth. After all, unlike M-theory, God’s Kingdom is not limited to 10 spatial dimensions and 1 time-dimensions. Given God’s transcendent nature, we can expect that the world we live in being seen from God’s Kingdom is space-time being stretched out like a piece of paper. At a glance from the eternal realm, all of history will be presented before Him. From every little action that we do in secret to future wars that are yet to take place, He sees them all through this membrane that transcends the limits of physics.
Surely, God’s wisdom is way beyond our finite capacity to understand. And when we peel into the vast richness of quantum mechanics, we know that the glory of God is there also.
