Seven Heavens
Scientists have just confirmed the existence of Dark Matter. This mysterious Dark Matter is invisible however it provides the bulk of gravity that holds galaxies (not the regular matter that forms stars and planets). This invisible Dark Matter has weird collision properties (collisionless). Simply put: we cannot see Dark Matter nor collide with it but we can detect its gravity.
In this image, two huge clusters of invisible Dark Matter (in blue) clashed with each other:
With each cluster having a mass of 10,000 galaxies (each cluster a quadrillion times the mass of the Sun, 1015)!!! (See: Universe Today). However upon impact, instead of disintegrating into smaller pieces, they passed through each other unscaved! This means that they did not collide with each other either! They simply passed through each other!!!
In order to explain why this invisible Dark Matter neither collided with each other, nor did it collide with us but still we detected its gravity, physicists and cosmologists are working on theories with extra dimensions:
"This means that the world at very small scales is not made up of particles living in three spacial dimensions, but perhaps strings and branes living in nine dimensions. String theories are the most active area of research in physics today..."
"Gravity, Black Holes, and the Very Early Universe"; T.Chow, Springer 2008 (p. 108)
Traditionally scientists thought that we live in a four dimensional universe: Time and the usual three spacial dimensions of length, width and height (x,y,z). However today there is evidence for six extra spacial dimensions. So we cannot see nor collide with this Dark Matter because it is mass in the remaining six extra dimensions.
According to the Quran, we cannot see nor collide with Jinn but they have weight:
[Quran 55.31] We [Allah] will settle your affair, both you of weight (man and jinn)
The Jinn have weight means that we can detect their gravity and they can detect our gravity. So according to the Quran we cannot see the Jinn nor collide with them but we can detect their gravity.
Just as the Jinn is of different type that we cannot see nor collide with but we can detect their gravity, there are six other Heavens that we cannot see nor collide with either but we can detect their gravity, superimposed above the visible one:
[Quran 41.12] So [Allah] decreed them as seven heavens (one above the other) in two days and revealed to each heaven its orders. And We [Allah] adorned the lowest heaven with lights, and protection. Such is the decree of the Exalted; the Knowledgeable.
According to the Quran, only the lowest heaven has visible light. This means that this Dark Matter exists in the six Heavens superimposed above the lowest one. Also according to the Quran, each of these remaining six Heavens is of a different type and each has its own planets like Earth:
[Quran 65.12] Allah is the one who created seven Heavens and from Earth like them (of corresponding type); [Allah’s] command descends among them so that you may know that Allah is capable of anything and that Allah knows everything.
Earth is not a unique planet in Islam. Other planets like Earth do exist throughout the other six Heavens. It is just that we cannot see them nor collide with them but we can detect their gravity.
General relativity predicted gravitational lensing, that is, the gravitational field generated by a galaxy causes the light passing through it to bend (change direction). Dark Matter does not emit any light but scientists can still map its location by using gravitational lensing, that is, by detecting where light is bending in places where it shouldn't. In the above image
and video light gets bent by invisible dark matter in places
where it shouldn't:
Moslems say that this is how God challenges nonbelievers to detect the remaining six superimposed Heavens:
[Quran 67.3-4] [Allah] is the one who created seven superimposed Heavens. You do not see variations in the formations of the Compassionate, so redirect your sight, do you see any creation? Then redirect your sight again, your vision returns to you in defeat and regret.
Today they looked again and found those creations indeed.
