Making a real-life time machine is a little bit more complicated than it is in theory.

The main problem in time travel theories is how we get back from the future? We can accelerate the craft to a speed that is near the speed of light in particle accelerators. The weight of those crafts would be less than a couple of grams. And that thing would allow sending nanotechnical craft to future. But how to make that craft return? The time dilation is the key to travel to the future can reach by accelerating the object to the light speed. By using a great Hadron Accelerator. But returning from the future is a little bit more complicated. And without the ability to travel back from the future the time machine is useless.

This text is writing about a theoretical time machine. The world is full of theoretical machines. Things like photon and antimatter rockets along with the WARP-engines are the top of theoretical research of rocketry. The idea of the time machine is the same way theoretical way to think very simple to accomplish. The needed thing is only the cylinder, which rotates with the speed of the light. Throughout history. Many people have tried to make time machines and one of the most promising things is the so-called Tipler cylinder.

The idea of thins very fast spinning cylinder or Tipler cylinder is that the Tipler Cylinder is in the tube, where are the stator coils. The cylinder itself rotates in that chamber by the electric field like the rotor of the electric engine. So when the speed of the cylinder is near the speed of light time dilates in it. The return of the time machine would be the same way easy. When our hypothetical time traveler wants to return that person should just put plasma rotate with the speed of light around that cylinder. But a practical solution is very hard to make.

H.G Wells time machine

So on this point, I must say that theoretically there is nothing wrong with the H.G Wells time machine. There are two rotating plates. The bigger one, which rotates near the speed of the light causing the time dilation. That effect makes it possible to travel to the future. And the smaller one would be the cylinder, which makes the virtual crossing of the light speed possible. But in real life, there is more than one problem with that thing.

The plates would crash because the needed rotation speed is so high that the centripetal force will destroy them. The needed energy layer is so high that this system is impossible to make. But as you know. there is the possibility to replace the physical parts of the system by using particle accelerators. In that case, the form of the system is particle accelerators, which are like tubes around the craft.

There are horizontal and vertical particle accelerators, and when the ions would put to run in tube one with the speed of the light, that thing would stop or slow the time in the capsule. And when the second accelerator will start the time will start to run backward. Because of the virtual crossing of the speed of the light. But the practical solutions are more difficult to make than the theoretical machines.

Theoretically making a time machine is simple. The creator of that machine must just make the craft, which would reach the speed of 99% of the speed of light. Then there should be a cylinder in the front of the vehicle. And that cylinder would put rotate with the speed that is near the speed of the light. But the fact is that this thing is a little bit more complicated to make in real form than making a theoretical version of this system. But let's take a little bit back. The time dilation would make the time stop in the system, but could the front line of the frontal cylinder cross the cosmic speed limit?

The problem with the time machine is to turn theory into practice. If that thing is possible, the time machine is done, and the only thing that the creators must do is to develop the antimatter engines and materials that are not breaking in the extreme high centripetal force. The problem with time travel is that we could travel to the future in a really easy way. We must just accelerate the craft to the speed of light, and time stops in it. But the problem is, how we get back from the future?

Making a black hole could make time travelers possible to return from the future.

If we are thinking of the possibility to make the singularity on the Earth, that thing would make it possible to travel back in time. The idea is that inside the black hole, behind the event horizon the time could travel backward. But the creation of the singularity in the atmosphere is a really risky business. The singularity must not be the so-called stable singularity. It should get its energy from the time machine itself.

The problem with black holes is that the creation of them is very difficult. The singularity needs so much energy. And if the singularity turns stable, what means it would be self-maintaining that thing would destroy the entire Earth. So the requirement is that when the energy production of the time machine is cut the singularity must also vanish.
