Astronomers detect signals from space that seem to defy Einstein's laws

Astronomers from around the world have detected phenomena that challenge Einstein's laws. Although this is not about matter traveling faster than light, the observations generate optical illusions that can reveal secrets of the universe.

These effects allow scientists to study stellar explosions, jets of particles from black holes, and regions of extremely high energy. They offer a unique perspective on extreme processes in the cosmos.

History and early explanations

The phenomenon is not new. In 1901, Thomas Anderson saw that the remnants of Nova Persei appeared to expand five times faster than light.

Decades later, Paul Couderc proposed the concept of a "light echo". The geometry in which the radiation reaches Earth creates the illusion of impossible speeds. Since then, cases have been recorded in supernovae, pulsars, and active top-tier nuclei.

Recent example: Centaurus A galaxy

In 2024, researchers observed that a jet from Centaurus A showed different values depending on the wavelength: 80% of the speed of light in radio, and up to 2.7 times that value in X-rays.

According to astrophysicist David Bogensberger, this indicates the coexistence of two plasma populations moving independently. This is key to understanding the dynamics of these massive energy jets.

Relativistic jets

Matt Nicholl, from Queen's University, explains that the apparent superluminal speeds help calculate the energy of the jets relative to Earth. If they point directly at us, they appear to exceed Einstein's limit.

This data is vital for studying extreme phenomena such as gamma-ray bursts or neutron stars, which are impossible to reproduce in terrestrial laboratories.
