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?
Have you ever wondered how long a billion years really is? Our human brains struggle to comprehend the vastness of time, but imagine this: every second represents 1.5 million years. Now, buckle up and join us on a musical train ride through Earth's entire history, compressed into just one hour. Prepare to witness the incredible story of our planet's evolution.
Have you ever pondered the enigma of life's evolution on our planet? For 3.7 billion years, life has been a silent witness to the universe's unfoldings. Yet, for most of this expanse, the story was one of monotony—microscopic cells drifting in primeval waters, devoid of the vibrant complexity we see today. So, what sparked the leap from simplicity to the kaleidoscope of life we know? The answer lies in a paradox: oxygen, the very element that sustains us, also triggered a revolution that shaped the course of life on Earth.
