The universe is massive and filled with mysteries. Scientists have spent years looking up at the stars, eager to uncover its secrets.
Even though we’ve learned a lot, some questions still haunt us. If black holes and alien invasions seem scary, wait until you hear what Professor Brian Cox is truly worried about.
When asked if we might find alien life, this famous physicist revealed his biggest cosmic fear:
“I would be delighted if we found life elsewhere because I feel it would take some of the pressure off,” he said in a BBC Earth Science video.
Then he shared something more unsettling:
“My fear, the thing that keeps me awake at night, is that life is extremely rare in the universe and complex life is so rare that we might be the only planet in the Milky Way where complex life exists currently.”
Imagine that! In the vast Milky Way, which has about 100 to 400 billion stars, Cox worries that Earth might be the only home to intelligent life.
He isn’t the only one grappling with this concern. The Fermi Paradox points out a curious contradiction: The universe is big, and the chances of alien civilizations seem high. Yet, we haven’t found any solid evidence of them.
What if civilizations always self-destruct before they can connect with others? In his humorous style, Cox joked that maybe the lack of contact is because civilizations fall apart right after creating the internet:
“I’m increasingly of the view that the reason for The Great Silence is that civilizations are inevitably crushed by the weight of n**heads shortly after inventing the internet.”
Even with his worries, Cox keeps a sliver of hope for finding alien life. He joked that if a flying saucer landed during one of his interviews, he would feel a sense of relief:
“Thank God that it’s not only down to us now, because you know, we’re not making a very good job of it,” he said with a laugh.
If life is indeed rare, then we have a big responsibility to care for our planet, and that’s not an easy task.
As scientists continue the search for extraterrestrial life, Cox’s worries linger: What if our universe is vast but also empty? With tools like the James Webb Space Telescope and ongoing exoplanet studies, we might find some answers soon. Until then, the question of being alone in the universe will keep many people, including Brian Cox, awake at night.
