 Why would we want to dig a tunnel through the moon?

Benefiting the gravity energy

If we would want to make gravity energy digging the hole through the small object like the moon is one of the most suitable things, what we can do for making that kind of thing true. The gravity energy doesn't need sunlight, and that is more stable than nuclear reactors, but the thing requires the object, which is big enough. 

Transforming the gravity energy to electricity would be easy, and the weight must just tie to the wheel of the generator, and back and forth moving weight would just give enough speed for that wheel. If there is no atmosphere on that planet or moon, the weight should move a very long time, because the friction is minimum in that case. 

But what if researchers want to build the linear particle accelerator through the moon?

That kind of linear particle accelerator would give the new abilities to make the scientific research with a very powerful tool, and that allows us to make the linear particle accelerator, which is 3 474,2 km long. And that thing can use even more powerful energy loads than the cyclotrons. The particles could accelerate to a higher speed than cyclotrons because the trajectory of the particles is straight. 

But there is one very special thing on the moon, and that thing is that in the middle of the moon, the gravity turns suddenly to zero. That thing makes it possible to test, what happens when the extremely fast particles would suddenly turn zero. And this makes so-called "quantum rabbit" tests possible.  

That term means that the particle would accelerate to near the speed of the light, and then suddenly release to a zero-gravity environment. The problem is that that particle will be suddenly driven through the point, where the gravity is zero. The problem is that we cannot create a zero-gravity point on the Earth, without digging the tunnel through our planet, but the moon is colder what makes that project lighter.  

Every gravitational object causes that the universe is curving around the object. And that thing would make the time moving slower than in the "straight universe". So what happens if the gravitational field of the object would suddenly remover? Would that thing affect time dilation or not? That is a thing, that makes time dilation extremely interesting is that Einstein explained that nothing can travel faster than light. 

But the speed of the light is not stable. The idea is that the massive objects are pulling the particles to them, and the gravity lens shows that the gravity affects the speed of the photons. So that thing means that some photons are traveling faster than others. 

Nothing can cross the speed of light, except for light itself, but the speed of the light is the cosmic constant. The thing that the speed of light would be measured to the same speed is that near the gravity centers the time is moving slower. 

And if the observer would be in the gravity field the speed, what that observer would get while measuring the speed of light, is that the light would travel between two points with cosmic constant  299 792 458 m/s as everywhere. But the observer, who stands outside the gravity field would get a different result because the time is moving slower in the gravity field. 

One of the most interesting questions is that, what happens, if the particle would suddenly go from the gravity field to zero-gravity when the time dilation would remove in the extremely fast. Would the quantum field take a touch to those particles, that they would be slowing to the speed of 299 792 458 m/s, or would they jump to the tachyon universe?
