For decades, we’ve dreamed of visiting other star systems. There is only one problem – it’s so far away, with conventional spaceflight it would take tens of thousands of years to get to even the nearest problem.
However, physicists are not the type to give up easily. Give them an impossible dream, and they will give you an incredible virtual way to make it a reality. Could.
at New study By physicist Erik Lentz from the University of Göttingen in Germany, we may have a viable solution to this dilemma, one that could be more feasible than other potential warp drives.
This is an area that attracts a lot of bright ideas, each offering a different approach to solving the puzzle Faster than light Travel: achieving a way to send something through space at breakneck speeds.
However, there are some problems with this idea. 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 is something we would need for any flight measured in light years.
But that hasn’t stopped physicists from trying to break the global speed limit.
While pushing matter beyond the speed of light will always be important, spacetime itself has no such rule. In fact, the universe’s far distances are already stretching faster than its light hopes to match.
To bend a small bubble of space in a similar fashion for transportation purposes, we need to solve relativity equations to create an energy density lower than the vacuum of space. While this type of Negative energy Happening on a quantum scale, sufficient accumulation in the form of “negative mass” is still a realm of alien physics.
In addition to facilitating other types of abstract possibilities, such as wormholes and time travel, negative energy can help reinforce what is known as Alcubierre Warp Drive.
This contemplative concept takes advantage of the negative energy principles of deforming space around a hypothetical spacecraft, enabling it to travel effectively faster than light without challenging conventional physical laws, except for the reasons explained above, we cannot hope to provide such an imaginary source fuel to begin with.
But what if it were possible somehow to achieve faster-than-light travel maintaining his confidence in Einstein’s relativity without requiring any kind of strange physics that physicists had not seen before?
In the new work, Lentz suggests one way in which we can do this, thanks to what he calls a new class of superfast. solitons – a type of wave that maintains its shape and energy while moving at a constant speed (in this case, a speed faster than light).
According to Lentz’s theoretical calculations, these ultrafast soliton solutions could exist General Relativity, And it is obtained from positive energy densities only, which means that there is no need to think about sources of strange negative energy densities that have not yet been verified.
With sufficient energy, these celons’ configurations could act as “twisted bubbles,” capable of moving in ultra-brightness, and theoretically enabling an object to pass through spacetime while protected from intense tidal forces.
It is an impressive feat for theoretical gymnastics, although the amount of power needed means that this torsion drive is only a hypothetical possibility for now.
“The energy required for this light-traveling engine that includes a spacecraft with a radius of 100 meters is on the order of hundreds of times the mass of Jupiter,” Lentz says.
“The energy savings would have to be substantial, about 30 orders of magnitude, to be within the range of modern nuclear fission reactors.”
While the Lentz study claims to be the first known solution of its kind, his paper arrived at almost the same time as another recent analysis, published just this month, that also proposes an alternative model for a physically possible torsion drive that does not require negative energy to operate.
Both teams are in touch now, Lentz says, And the researcher intends to share his data more so that other scientists can explore his figures. Plus, Lentz will explain his research in a week – in YouTube Live Show March 19.
There are still a lot of mysteries to be solved, but the free flow of these kinds of ideas remains our best hope for having a chance to visit those distant, twinkling stars.
“This work has moved the problem of traveling at faster than the speed of light one step away from theoretical research in basic physics and closer to engineering,” Lentz says.
“The next step is to figure out how to reduce the astronomical amount of energy needed within today’s technologies, such as the modern large fission nuclear power plant. Then we can talk about building prototypes.”
The results are reported in Classical and Quantum Gravity.
