##### Spacetime tunnel

## A spacetime tunnel joins together two points in time and space.

A person can travel in time only when they end up in hyperspace or outside of spacetime. According to general relativity, ‘there’ the spacetime has curved to infinity (or time has infinitely slowed down and the distance of two points in space has also infinitely decreased). Such an area of spacetime (where the spacetime ceases to exist) exists, for example, in the centres of black holes and therefore black holes can be ‘gates’ through which it is possible to enter hyperspace.

### Spacetime tunnels enable travelling in time

It has been generally acknowledged in the scientific world that it is possible to travel in time through spacetime tunnels or wormholes. Wormholes also help in space travel as by moving through a spacetime tunnel, vast distances in space will get a lot closer to us. A spacetime tunnel, popularly known as a wormhole, is a curve of time and space that joins to points in spacetime and enables to move from one moment in time into another or move from one point in space into another in a moment or 0 seconds. Theoretical physics has discussed the actual existence of wormholes extensively, which mainly arises from the existence of different interpretation of the physics theories of time and space. For example, a black hole can simultaneously be the entrance and exit of spacetime. As we know, gravitation is a curve in spacetime and on the Schwarzschild event horizon that is in the centre of black holes, spacetime has curved to infinity. Figuratively, the Schwarzschild event horizon is a border of spacetime, where the existence of time and space actually ends. By now, a new theory of physics has been developed that proves that the event horizon, on which time and space have curved to infinity, can also be physically interpreted as the entrance and exit of spacetime. Therefore, it can be said that spacetime tunnels exist in the Universe as black holes exist.

The question now lies in how the humankind would be able to artificially create such wonderful spacetime tunnels which would enable people to move in time and teleport in space. By now, this question has also been answered. Firstly, unfortunately black hoes cannot be created and used as they are clearly dangerous to our planet and the body near the black hole. As we know, nothing escapes the centre of a black hole, not even light. The black hole is created by huge mass. According to the principle of equivalence of mass and energy in Albert Einstein's theory of special relativity, a black hole or a tunnel in spacetime could also be created by energy. But the difficulty is that a tunnel in spacetime which could be used by a person can only be created by massive energy and we have nothing that would provide this energy. This is the whole difficulty in creating spacetime tunnels. As a comparative example – the energy required to create an object that would be the size of a spacetime tunnel passing through a person, a lot more energy would be required than the amount of energy equivalent to Earth’s mass. For a long time, the issue of energy was the greatest obstacle in creating spacetime tunnels. But now, new discoveries in theoretical physics have found a completely new way to practically solve this problem. It has become clear that there are two ways to actually create spacetime tunnels, the same way as in nuclear energetics, nuclear energy can actually be produced in two different ways. For example, the nuclear energy produced by humans is based on the energy released by splitting heavy nuclei or joining light atomic nuclei Something similar applies to creating spacetime tunnels. For example, a spacetime tunnel can be artificially created by using massive energies (as was mentioned above), but also by using extremely small energies. As energy amounts equivalent to the mass of planets cannot be produced or used in practice, the only remaining option is to use extremely small energies, which is certainly within the current technical capacities of the humankind. In addition to mass, time and space are also warped by energy and, for example, an electrical field has energy. Therefore, the mass and electrical charge of a physical body affect the geometry of spacetime. But what are extremely small energies?
This is covered by scientific analysis in Marek-Larks Kruusen’s book Maailmataju, in the part covering the physics theory of time-travel that describes the technical possibility of humans actually travelling in time.

### Singularity in the spacetime hole

The field of gravitation is a curve in spacetime caused by extremely heavy masses. This curve in spacetime is expressed in the fact, that the more we move towards the centre of the field of gravity, the more time slows down and the shorter the distance between two points in space becomes. Such a transformation of time and space continues until a specific distance from the centre, and this distance is described to us by the Schwarzschild radius R. This radius shows the distance from the centre of the field of gravity, starting from which time t and space l have transformed to infinity, i.e. starting from which the infinite curving of spacetime begins or the spacetime ceases to exist completely. This is why nothing can exist within the area inside Schwarzschild radius R of the black hole or spacetime hole, which is sometimes also called the event horizon. This also means that there cannot be any singularity in the centre of the black hole. Singularity is just a point, starting from which the Schwarzschild radius R is measured and which determines the ‘size’ of the black hole or spacetime hole, i.e. the size of an imaginary sphere in space, starting from which the infinity curve of spacetime becomes more and more level as the distance from the centre increases. This is why the mass of a black hole cannot exist within the event horizon, but is outside of it, as is also in case of stars and planets.
The event horizon is completely spherical and it does not rotate. It can only orbit around another celestial body.

For a long time, the development of physics was stuck in the seeming mysticism of quantum mechanics and the theory of relativity.
The theory of time-travel is a continuation of these two theories and also combines them.
This has also been implied in the magazine Imeline teadus (No. 10/2014, page 88-95), which writes:
‘After years of research, physicists have still not been able to join together the two theories (theory of relativity and quantum mechanics), which are the basis of modern physics, but the solution to the mystery might be hidden in the question of time-travel.’ Creating a time-machine is as important for the future development of physics as was discovering that the speed of light in vacuum is constant at the end of the 19th century. It is very important to understand the physical nature of the Universe and this is revealed particularly in the theory of time-travel.

## The first technical possibility in history to create a loop-shaped tunnel in spacetime: model 2022

At the moment, European Space Agency (ESA) has been chosen for it.

My proposal is that the engineers and scientists working for ESA could finish off the technology I propose. In this way, I would like to collaborate with ESA to develop technology and science concerning tunnels in spacetime. Technology concerning tunnels in spacetime could replace rocket technology in the future. I have evidence-based physical and mathematical science and an early stage technical model for creating a tunnel in spacetime. ESA could test the technology that I propose in its laboratories and other industrial infrastructure. In addition, we could continue research and technology development activities together.
