Atom clocks can measure dark matter.

"A groundbreaking new study published in Nature Astronomy suggests that studying an atomic clock on a spacecraft orbiting close to the Sun, inside the orbit of Mercury, could be the key to unlocking the mysteries of dark matter. The research offers a potentially game-changing approach to understanding this elusive and enigmatic substance that is thought to make up much of the universe."

Dark matter is the gravitational effect that is unknown. There is the possibility to create a telescope that can use measuring dark matter. The idea is that the telescope is a combination of the laser-rays, that measure gravitational waves, and atom clocks which measure gravitational waves. The idea is that if there is some kind of stable gravitational anomaly. The atom clocks can detect is by measuring time dilation. 

And the laser rays can separate gravitational waves from the stable gravitational effect whose source is unknown. The difference between dark matter and gravitational waves is that. 

Dark matter forms (or it should cause) a stable gravitational effect, that remains in one place. Or, it travels too slowly, being a gravitational wave. And gravitational waves are transitory phenomena. So if the atom clock will transfer near dark matter glimpse. That thing could cause time dilation. 

There are two main possibilities for what dark matter could be: 

*It could be yet unknown particles

*Or it can be standing gravitational waves. In that model gravitational maser-effect is the thing that forms the dark matter. 

The thing is that. Dark matter can travel across the universe. If it is a form of similar particles, with visible material. In cases when the speed of the gravitational effect is slower than gravitational waves, there is suspicion that some, yet unknown, particles are causing that effect. The speed of gravitational waves is the speed of light. 

And if the gravitational effect travels at a lower speed. That means there is something that looks like a planetary cloud. But if that thing is invisible, it means. That there could be the first evidence about the form of dark matter. 

The measuring gravitational effects of dark matter requires zeptosecond accurate atom clocks. The system detects the changes in the gravitational field. Those atom clocks will put in certain distances from the Sun, and they measure the gravitational effect's time dilation. 

The system can use the difference between those atom clocks to measure the gravitational effect's speed. And laser rays are confirming. That there are no gravitational waves that are causing changes in gravitational fields. 

There are multiple very accurate radio objects in the universe. And the changes in their flashes also depend on the energy that travels near them. The problem with time dilation is that the reason for it can be gravitational waves. It can also be a high-energy impulse that impacts the target. So those time dilations must be proven caused by the gravitational effect that is not gravitational waves. 

Things like kilonovas and exploding or colliding black holes are also making a situation where shockwaves can affect dark matter. We know that there is one common force. That causes interaction between visible and dark matter. That thing is gravitation. That means dark matter could form black holes. But the problem is: how to confirm that dark matter formed a black hole.
