What would happen if we lose the moon?
It is the pull of the Moon’s gravity on the Earth that holds our planet in place. Without the Moon stabilising our tilt, it is possible that the Earth’s tilt could vary wildly. It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages).
What would happen if the moon split in half?
If the moon were half its mass, then the ocean tides would have been correspondingly smaller and imparted less energy to it. So a less massive moon would nonetheless end up closer than the real one to Earth. The energy given to the moon comes from Earth’s rotation—and to compensate, our planet is slowing down.
Does Moon has a crack?
Recently, researchers were baffled by a discovery of a strange crack on the Moon’s surface, which is continuing to expand. Large scale research conducted by the Smithsonian Institute to study the fault on the lunar surface using sensors installed during Apollo 17 has found the faults.
Why did Allah split the moon?
He holds that perhaps all three are applicable to the verse: Moon once appeared cleft asunder at the time of Muhammad in order to convince the unbelievers. It will split again when the day of judgment approaches (here the prophetic past tense is taken to indicate the future).

Are diamonds in space?
Diamonds are common in highly shocked ureilites, and most are thought to have been formed by either the shock of the impact with Earth or with other bodies in space. However, much larger diamonds were found in fragments of a meteorite called Almahata Sitta, found in the Nubian desert of Sudan.
Are there diamonds in lava?
There, a type of material called kimberlite magma forces its way up from deeper in Earth’s mantle, cracking the solid rock. As it rises, the magma collects fragments of rocks, like floodwaters picking up silt and gravel. Some of these fragments contain diamonds.
