Have you ever gazed up at the night sky and pondered the vastness of the universe? The celestial tapestry we see is but a fraction of what truly exists. Beyond the twinkling stars lies an enigmatic realm, where the most powerful objects in the cosmos reign supreme. Enter the world of quasars—beacons of immense energy that reshape the very fabric of the universe. But what are they, and how do they influence the cosmos?
In 1939, Albert Einstein declared the non-existence of black holes in nature. Fast forward a quarter-century, and the discovery of quasars challenged this notion. These enigmatic point-like sources of intense light at cosmological distances were later attributed to supermassive black holes at the centers of galaxies. Could it be that one such black hole influenced the evolution of life on Earth?
