The theory that contradicts Einstein. The journey at a speed faster than that of light could become a reality

For decades, we dreamed of visiting other stellar systems. There is only one problem - they are so far away that, with conventional spaceflight, it would take tens of thousands of years to reach even the nearest.
But physicists are not the kind of people who give up easily. Give them an impossible dream, and they will give you an incredible and hypothetical way to turn it into reality.
In a study conducted in 2021 by physicist Erik Lentz at the University of Göttingen in Germany, we could have a viable solution to this dilemma, and it may prove more feasible than other possible options.
In conventional physics, according to Albert Einstein's theories of relativity, there is no real way to reach or exceed the speed of light, which we would need for any journey measured in light-years.
However, this didn't stop physicists from trying to exceed this universal speed limit.
While pushing matter beyond the speed of light will always be a big mistake, space-time itself doesn't have such a rule. The distant limits of the Universe are already stretching at a greater speed than its light could ever hope to equal.
In this system, we should solve the relativity equations to create a lower energy density than the vacuum. While this type of negative energy occurs on a quantum scale, the accumulation of a sufficient amount in the form of a "negative mass" is still a subfield in the field of exotic physics.
In his recent paper, Lentz proposes a way we could do this, thanks to what he calls a new class of hyper-fast solitary waves - a type of wave that retains its shape and energy as it moves with a constant speed (and, in this case, a speed higher than that of light).
With sufficient energy, the configurations of these solitons could function as bubbles capable of moving faster than light and which, in theory, would allow an object to pass through space-time while being protected from extreme forces.
It is an impressive theoretical achievement, although the amount of energy required means that this type of propulsion is only a hypothetical possibility at the moment.
"The energy required for this propeller to move at the speed of light from a spacecraft with a radius of 100 meters is hundreds of times greater than the mass of Jupiter," Lentz said.
There are still a lot of puzzles to solve, but the mere fact that these hypotheses exist means that we are one step closer to turning them into reality.
