Time machines, and the hypothesis about a time traveler, who denies COVID-19

There is one very interesting version of the time travel and COVID-19, and that very nasty idea goes like this. The person would travel in time and attempt to find the first person, who is infected by COVID-19, and during that operation, the time traveler would accidentally be infected by COVID-19, and become the "patient number one". So can we someday travel in time and then save the world from things like COVID-19? What does that thing require? 

The fact is that we are traveling time right now because time on Earth travels slower than orbiter and outer space. And that means that time travel is possible, but we would need a huge energy load for that thing (1).  

Could we change the spacecraft to a black hole, and then disassemble that black hole, when we need to go to operate somewhere in the past or future?

The time travel is possible if we are thinking about the time-dilation. If we are making spacecraft what travels with the speed of light, the time would stop inside it. This kind of effect could be done by using the great "Hadron" particle accelerator, where the capsule would travel in the magnetic track and the speed of the craft will rise to the speed of light, that thing allows us to travel in the future. 

But how to cross the speed of the light, when time starts to travel backward? In some speculations at the front of the craft would be formed the artificial black hole. And then the speed of the light can be crossed in the point of the event horizon. The craft itself can turn to the black hole itself by pumping energy to it. When the energy level will rise high enough that makes it the particle, where the light cannot escape. But the problem is how to remove the energy from the craft, and make it come back to normal particle?

If we sometimes want to make a time machine, what uses black holes, that requires that the black hole can also be vaporized, that is the requirement for the successful time traveling. If that problem is solved, that craft can come out from the black hole if the black hole would put to vaporize. So the energy of the singularity must conduct to somewhere if we would want to create a successful time machine. 

The "Tipler Cylinder"(2)and traveling back in time.

Another version is to create the spacecraft, which is cylinder-shaped. In that case inside the spacecraft would be installed so-called Tipler Cylinder. The Tipler Cylinder can have two layers. The outer layer, and the inner cylinder, what hovers freely in the Tipler Cylinder. 

And the outer layers would start to rotate extremely fast, which means that the craft can virtually cross the speed of the light if the cylinder is installed in spacecraft, which travels near the speed of the light. But the fact is that accelerating the cylinder would take an extremely long time. 

The fact is that also normal ion engine could have extremely high specific impulse if the ions would accelerate to enough high speed. In this case, the great hadron accelerator can put at the back of the spacecraft. And the powerful accelerator could raise the speed of the spacecraft to near the speed of the light, and then the Tipler-cylinder will start to rotate inside it. 

At this time the time machines are only on the theoretical level, but there is some theoretical research made about this kind of system. Things like "Tipler cylinder" seem the most promising answers for that kind of problem. In the "Tipler cylinder" the fast rotation movement of the cylinder-shaped structure will cause time dilation. 

If we think about the centripetal force there is a possibility that the high power magnetic field would pull the cylinder and keep it in one piece. So the theoretical "Tipiler Cylinder" is the metal cylinder, which hovers at the magnetic chamber, and the magnets will keep it rotating and press it together. And the crew module would be the cylinder, what hovers in the "Tipler Cylinder"

But the rotation speed of that cylinder must be near the speed of the light. And in some theories, the cylinder can be virtualized. The idea is that the plasma would start to rotate around the Tipler Cylinder. That means that the cylinder is stable, but it rotates ionized gas around that structure, and this thing causes the time dilation in the plasma layer.

Could we deny things like COVID-19 epidemics by using time machines? 

Even if we would someday make a time machine, what can travel in the past, we must remember that we need very high accuracy if we want to find a certain case, and deny it. And here we are not talking about the possibility to find one certain person from the population of Chinese. There is a possibility that the time traveler could travel in the hospital, find the files of the infected person number one, and deny the infection by making the animal, which transfers the virus to the "patient number one" vanish. 

But that kind of thing requires very high accuracy in the time travel. That accuracy is required because a certain point of the time can be found. And this hypothetical time traveler can find a certain point, where the time machine will materialize in the time. But the thing is that the time machine is on the theoretical level, and if we would want to affect the past, there is a possibility, that denying things like "patient one" in the COVID-19 epidemic would have a larger-scale effect than we even thought.
