On the Day of Resurrection, the state of the air will be as such

In that day Allah will destroy this world, because the command of Allah Almighty will no longer be. The day of destruction of the world is called resurrection. But before the beginning of the resurrection Allah will show some signs.
Israfil (peace with him) will be blown into the trumpet, then you will come into the crowd. And heaven will be opened, so that it will be of many gates. (Nabah, 78: 18-19)
And the heavens will be divided. As a result, it will be weak on that day. (Haqqa, 69:16)
The idea of ​​exposing heaven is a concept that relates to 'Black Holes' or 'Black Holes'. For example, such doors can be exposed as the gate to heaven or hell.
The black hole refers to the positions in the sky that are emptied by the death of the constellations. Death of a star means that the level of controlling power is gone. When the stars die, they are concentrated by the influence of their gravity until the molecules are at the core.
A dead star has reduced the size of a few million times of its true size. If the dead star is a small star like our sun, it becomes a pulsar (small stars that can only be transmitted via the X-ray signal) and every 0.03 second dye emits. . If the dead star is large, the gravitational distribution is so intense that it does not stop at the nuclear level, but it continues until the concentration of all its substances and energy goes to a point called singularity. This singularity is the super-cosmic black hole. Such gravity is so intense in the particles that even the light can not spread until it disappears and they disappear. Therefore, these black holes are called.
Astronomers believe that the connection between space and space can be divided into black holes by creating an entry behind this universe. In the current state of expansion of the universe, the artifacts in the black hole obstruct the door. This problem does not remain in the narrowing of the universe. On the Day of Judgment, the gravity changes of all space objects surrounding the earth and the surroundings. Time will also be associated with the contraction of space or the inversion of gravity. As a result of this space, space constraints will break the space and time structure and eventually the universe is split into the universe in the form of the gateway. In this verse (69:26) we must pay special attention. It says that the heavens will divide on the day of judgment and it will be fragile. His inevitable meaning is that the sky is not fragile in this growing state of the present universe. It is a fascinating thing that the description of the Qur'an Majid is very short, but still very important.
'When the sun (in the dark) is rolled back. And when stars will fall. And when the mountains are run. And when pregnant women of ten months are neglected. And when the wildlife is being assembled. And when the oceans will be ignited. And when the souls (together with the ordinary) are merged. And when the living cemeteries are asked. What is the crime he was killed? And when the heavens will be covered. And when the hell will be lit. And when paradise comes closer. Then everyone will know what he has brought? (Takbir, 81: 01-14)
