299,792km/s is the speed of light in a vacuum. As it stands, humans have only managed to attain speeds of ~11km/s, showing just how staggeringly fast light travels and the massive gap between it and our capabilities. For this reason, the idea of faster-than-light (FTL) travel remains firmly footed in science fiction, as opposed to reality – for now at least.
With an increasing understanding of just how vast the cosmos is and near-term endeavors that would have humans visiting Mars, there is no shortage of novel ideas exploring theoretical possibilities on how we can exceed, or at least approach, such speeds. And while humans are, no doubt, generations away (if ever) from developing viable technology to transport substantial mass at such speeds, there is the possibility that we may one day achieve this with regard to communications. In fact, a potential advancement in our understanding of, and approach towards FTL was recently detailed that may pave the way to this reality.
Establishing Light Speed Communications
In a paper titled “Hyperwave: Hyper-Fast Communication within General Relativity“, author Dr. Lorenzo Pieri outlined the use of what he calls ‘hypertubes' for achieving FTL communication. Essentially, these Hypertubes manage negative energy for accelerating and decelerating warp bubbles (Hyperwaves).
At the core of the paper is the idea of the ‘warp bubble', which was initially proposed by Miguel Alcubierre in 1994. This bubble is described as contracting space in front of it while expanding it behind. The purpose of this is to, theoretically, allow an object to move faster than light without breaching the speed limit set by Einstein’s theory of relativity. Notably, a key requirement for such a feat lay in the harnessing of “negative energy,” a phenomenon observed in the Casimir Effect, where quantum vacuum fluctuations generate measurable forces between objects occupying space in close proximity.
In the paper, the concept of a Hyperwave put forth by Dr. Pieri focuses on using small-radius warp bubbles for communication as opposed to transportation. The reason for this is due to the astronomical amount of energy required for such a process. By focusing on a warp bubble that is only required to transport data, the paper indicates that,
“…total negative energy requirements gets smaller than the energy contained in a lightning bolt, more than 70 orders of magnitude less than the original Alcubierre warp drive.”
These smaller bubbles could potentially encode and transmit information using modulated high-energy particle emissions, allowing for the transmission of complex data across vast distances at speeds FTL.
While the idea behind Hyperwaves is tantalizing, it is important to note that their practical implementation continues to present formidable challenges.
- Creating and stabilizing these small-radius warp bubbles
- Generating the necessary negative energy densities
- Precisely controlling the warp bubble dynamics
Despite these hurdles, the paper is at the very least an interesting look into the research and ideas being explored surrounding the idea of FTL technologies. While highly theoretical and far from practical application, this approach to FTL communication, if realized, could revolutionize information transmission, with profound implications for space exploration and global communication networks.
Missions to Mars
Interestingly, faster-than-light (FTL) communication could one day play a transformative role in future missions to Mars. Here are a few examples of how it could impact missions to the red planet in the coming decades/millennia if it becomes feasible:
- Instantaneous Communication: Current communication with Mars involves a time delay ranging from 3 to 22 minutes each way, depending on its position relative to Earth. FTL communication would enable instantaneous or near-instantaneous data transmission, dramatically improving operational efficiency and safety for manned missions and robotic explorers.
- Enhanced Mission Control: Real-time communication would allow for more direct and effective control of rovers and other equipment. This could lead to more complex and nuanced exploration, as instructions and adjustments could be made on-the-fly rather than pre-programmed or delayed.
- Rapid Response to Emergencies: In case of emergencies or unforeseen situations, immediate communication would enable a faster response, potentially saving lives and mission-critical equipment.
- Scientific Data Transmission: FTL communication could revolutionize the speed at which scientific data is sent back to Earth. This would accelerate the analysis and publication of findings, potentially speeding up scientific advancements.
- Interplanetary Internet: The establishment of a reliable, high-speed communication network between Earth and Mars could pave the way for an interplanetary internet, enhancing data sharing and collaboration between planets.
While the potential benefits of FTL communication for Mars missions are significant, these remain speculative until the underlying technology is developed and proven viable. For the foreseeable future, Mars missions will continue to rely on conventional communication methods within the constraints of the speed of light.
