Mauritius & Manchester Scientists: Probing Aliens Spotting Earth from Light-Years

Scientists from Mauritius and Manchester University have explored the possibility of an alien civilization detecting Earth from light years away.

Using crowd-sourced data to simulate radio leakage from mobile towers, they studied the potential signals that could be picked up by extraterrestrial beings.

Ramiro Saide, an intern at the SETI Institute, developed models to simulate Earth’s radio power as it rotates and mobile towers rise and set.

The team suggests that unless aliens are significantly more advanced, detecting current mobile tower radio leakage would be challenging.

However, as technology advances, more sensitive systems may increase our detectability.

Saide’s simulations reveal a significant contribution from developing countries, especially Africa, in Earth’s mobile radio signature.

Professor Mike Garrett emphasizes Africa’s success in skipping the landline stage of development and directly embracing the digital age.

Despite claims of Earth becoming radio quiet, Garrett argues that the proliferation of mobile communication systems globally has created a detectable spectrum for advanced civilizations.

Supervisor Dr. Nalini Heeralall-Issur supports Saide’s findings, highlighting the continuous progress in understanding exoplanets through missions like Kepler, TESS, and the upcoming James Webb Space Telescope.
