Although it has never happened before, the time travel brings some problems, for example, how can we exist to go back to a time when we would not exist? Or how would its existence be possible, in the first place, since your parents could they ever meet? Paradoxes like these were reviewed by Germain Tobar who found that "squaring the numbers" can make time travel possible without the paradoxes.

The dynamics for time travel
Check now how the physicist Germain Tobar, from the University of Queensland, in Australia, discovered how to make time travel possible without the paradoxes:
- Theory of General Relativity
Einstein, the creator of the theory of relativity, predicts the existence of time loops or time travel, that is, an event can be in the past and in the future of itself.
- Space-time can adapt and avoid paradoxes
As an example for this calculation, think of a time traveler to the past, with the aim of preventing a pandemic from spreading.
If that mission succeeds, the time traveler would have no disease to go back in time to defeat her.
That is, the work of physicist Germain Toba suggested that the disease, even with time travel, would manage to escape in another way.
- Research that makes time travel possible
The research brought another possibility, despite the difficulties of this type of trip.
In this way, time travel becomes possible if travelers were restricted to what they were doing, that is, so as not to prevent them from creating a paradox.
With that, the travelers could do whatever they wanted, but the paradoxes would not be able to be changed.
For this reason, scientists report that no matter how hard you try to create another paradox, events will always find a way to adjust and avoid inconsistencies.
