However, maybe you will change your mind after reading this page to the end.īefore I start to talk about the experiment setup that seems to be possible to let us communicate faster than light (FTL), I think it is beneficial for us to first understand the famous delayed choice quantum eraser ( DCQE) experiment, because the FTL-communication setup is based on the setup and understanding of the DCQE experiment. Work and it is just a waste of time to even think about it. So, you are sure that superluminal communication is never gonna Moving faster than light or sending information faster than light will violate the sacred law of causality. Massive object moving faster than light is impossible as shown in Einstein's special relativity. Massless object will travel in this speed in the vaccuum). This means there would not be the complications of the so-called 'twin paradox' whereby one twin traveling near the speed of light would age much more slowly than the other twin who stayed on Earth: in fact, according to the recent equations both twins would be the same age when reunited.When you see the title, you probably think that this is not gonna work, because you learned that the ultimate speed limit of the universe is the speed of light (actually every In addition, the solitons (warp bubbles) were configured to contain a region with minimal tidal forces such that the passing of time inside the soliton matches the time outside: an ideal environment for a spacecraft. In comparison, the current rocket technology would take more than 50,000 years for a one-way journey. That means an individual could travel there and back within their lifetime.
If sufficient energy could be generated, the equations used in this research would allow space travel to Proxima Centauri, our nearest star, and back to Earth in years instead of decades or millennia. No exotic negative energy densities needed. In essence, the new method uses the very structure of space and time arranged in a soliton to provide a solution to faster-than-light travel, which-unlike other research-would only need sources with positive energy densities. Lentz derived the Einstein equations for unexplored soliton configurations (where the space-time metric's shift vector components obey a hyperbolic relation), finding that the altered space-time geometries could be formed in a way that worked even with conventional energy sources.
A soliton-in this context also informally referred to as a 'warp bubble'-is a compact wave that maintains its shape and moves at constant velocity. Lentz noticed that there existed yet-to-be explored configurations of space-time curvature organized into 'solitons' that have the potential to solve the puzzle while being physically viable. Erik Lentz, analyzed existing research and discovered gaps in previous 'warp drive' studies. The research is published in the journal Classical and Quantum Gravity. This reignites debate about the possibility of faster-than-light travel based on conventional physics. In contrast, new research carried out at the University of Göttingen gets around this problem by constructing a new class of hyper-fast 'solitons' using sources with only positive energies that can enable travel at any speed. This type of matter either cannot currently be found or cannot be manufactured in viable quantities. To date, even recent research about superluminal (faster-than-light) transport based on Einstein's theory of general relativity would require vast amounts of hypothetical particles and states of matter that have 'exotic' physical properties such as negative energy density. If travel to distant stars within an individual's lifetime is going to be possible, a means of faster-than-light propulsion will have to be found.
