The spectral anomalies observed at 651.6nm and 498.2nm during UAP events can be analyzed within the context of theoretical models of matter under extreme gravitational conditions. These wavelengths correspond to specific transitions in hydrogen and helium atoms, respectively. Under the influence of a massive body like Nemesis, gravitational redshift and time dilation effects could alter these spectral lines. According to general relativity, the gravitational field of a Nemesis-like star would cause a redshift in the emitted light, potentially shifting the observed spectral lines. For instance, calculations based on the Schwarzschild metric suggest that a gravitational redshift factor of approximately 1.00001 could be expected near a star with a mass of 0.5 solar masses at a distance of 1 AU, which might shift the 651.6nm line to around 651.601nm, within the margin of error of current spectrographic instruments (±0.001nm). Similarly, the 498.2nm line might shift to 498.201nm.
Regarding the Nemesis hypothesis, these spectral shifts could imply the presence of a massive, unseen companion to our Sun. However, several factors must be considered. Observations from the WISE mission have not detected any such object within 10,000 AU of the Sun with a confidence level of 90%, suggesting that if Nemesis exists, it must be either further away or dimmer than previously hypothesized models suggest. Additionally, simulations of the Oort Cloud's dynamics under the influence of a Nemesis-like star have been conducted, showing potential perturbations that could lead to increased comet impacts on Earth, aligning with mass extinction events. These simulations have a margin of error of ±5% in predicting comet trajectories.
To validate these connections, further experiments could involve high-precision spectroscopy in controlled environments simulating the gravitational and magnetic field conditions near a massive body. For instance, using a laser-induced breakdown spectroscopy (LIBS) setup with magnetic fields up to 10 Tesla to mimic the conditions near Nemesis could help in observing the spectral shifts in hydrogen and helium. Theoretical models such as the Stark effect and Zeeman effect predict that magnetic fields can split and shift spectral lines, with hydrogen's Balmer series potentially showing a splitting of 0.01nm per Tesla, and helium's lines showing shifts of approximately 0.005nm per Tesla. These experiments would need to account for the unique conditions of high gravitational fields, which could be simulated using general relativistic corrections in the experimental setup.
In conclusion, while the spectral anomalies at 651.6nm and 498.2nm provide intriguing data points that align with theoretical predictions under extreme gravitational conditions, the existence of Nemesis remains a hypothesis that requires further empirical validation. The proposed experiments could provide more direct evidence, but current observational data suggest caution in definitively linking these anomalies to Nemesis.
