Seismic signals that were initially thought to be caused by an interstellar meteor hitting Earth ten years ago have come under scrutiny. Scientists who visited the supposed impact location of the meteor found tiny spherules on the seafloor, speculating that they contained evidence of alien technology. However, a new issue has arisen regarding the origin of these signals. According to planetary seismologist Benjamin Fernando of Johns Hopkins University, the seismic monitoring data used to track the path of the object entering the sea off the coast of Papua New Guinea might actually be attributed to a passing truck on a nearby road. Fernando explains that the signal changed directions over time, aligning with a road that runs past the seismometer. This has led researchers to question whether the signals were truly from a meteorite or just a result of terrestrial movements.

When a large chunk of rock enters the Earth’s atmosphere, it can explode before burning up completely. These fireball meteors, known as bolides, strike the Earth at a rate of a few dozen per year, with most falling over the ocean. Sophisticated tracking systems allow us to monitor their entry into the atmosphere and the strength of their explosions. One particular meteor, CNEOS 2014-01-08, caught the attention of astrophysicists Avi Loeb and Amir Siraj from Harvard University due to its anomalously fast velocity, suggesting an interstellar origin. While the researchers attempted to track and analyze the meteor, further investigation by Fernando and his team revealed discrepancies in the trajectory measurements obtained from seismic data. The precision of the trajectory was unusually high, even surpassing measurements from multiple seismic stations. This raised doubts about the accuracy of the original findings and led them to reevaluate the detected signals.

Fernando and his colleagues delved deeper into the seismic data from various monitoring stations around Papua New Guinea and Australia. By analyzing signals from different stations, they were able to trace the Manus Island signal to a nearby road, indicating that the meteor fell much farther away than previously thought. The discrepancy in the landing area suggested that the initial location estimates were incorrect, leading to doubts about the reliability of the findings. These findings highlight the need for careful analysis and validation of data before making extraordinary claims. To illustrate this point, Fernando mentions past instances where signals were misinterpreted, such as mistaking a microwave oven signal for a radio signal or a gamma-ray burst for space debris. Humans are noisy and messy creatures, making it challenging to distinguish natural signals from the surrounding noise.

While the discovery of meteoritic spherules on the seafloor may have sparked excitement about potential alien technology, the reality is far less sensational. Earth receives thousands of tons of cosmic spherules annually, making it difficult to link specific findings to a particular meteor. Furthermore, recent studies have cast doubts on the interstellar origin of the meteor, suggesting that the initial evidence may have been inaccurate. As Fernando points out, regardless of whether the seafloor findings were from a natural space rock or an alien spacecraft, the connection to the supposed meteor remains unfounded. This underscores the importance of rigorous scientific scrutiny when investigating claims of extraterrestrial intelligence.

The seismic signals attributed to an interstellar meteor ten years ago may have a more terrestrial explanation than previously thought. The complexities of analyzing signals and tracing meteor trajectories require meticulous attention to detail and rigorous validation. While the allure of uncovering evidence of extraterrestrial life captivates the imagination, scientific integrity demands careful consideration of the facts. As researchers continue to probe the mysteries of the universe, it is essential to approach extraordinary claims with skepticism and a critical eye.
