Humanity’s End Was Determined from the Start<\/a><\/h3>\n
The moment a species learns to manipulate its environment for gain is the moment the clock starts ticking on its demise.<\/strong><\/div>\n<\/header>\n

Given the vastness of the universe, it’s possible that 1 billion intelligent civilizations exist.<\/p>\n

So why is there no sign of these civilizations?<\/p>\n

It is likely that all advanced civilizations are eventually destroyed by a “Great Filter”. And it’s probable that humanity is currently going through its Great Filter right now.<\/p>\n

First, Let’s Examine Why Alien Life\u00a0Should<\/em>\u00a0Exist<\/strong><\/p>\n

The Milky Way, our galaxy, is home to approximately 100 to 400 billion stars. Assuming that a portion of these stars are central to solar systems, similar to our own, it’s conceivable that the Milky Way could contain tens to hundreds of billions of such systems.<\/p>\n

Adding to this, the discovery of thousands of exoplanets, many found in systems with multiple planets through missions like Kepler and TESS, reinforces the idea that planetary systems are a common feature around stars. This widespread occurrence of exoplanets suggests that a significant majority of stars throughout the universe might host their own solar systems.<\/p>\n

Expanding this view to the larger cosmos, with an estimated 2 trillion galaxies in the observable universe, each potentially holding as many stars as the Milky Way on average, the numbers become even more astronomical. This implies a universe where hundreds of trillions to quadrillions of solar systems could exist, each with its unique characteristics and potentially life-supporting conditions.<\/p>\n

To crudely estimate the number of solar systems with planets that have conditions favorable to life, let’s use the higher end of the estimate: one quadrillion solar systems in the universe. If 1% of these solar systems have planets with conditions favorable to life, there could potentially be about 10 trillion solar systems with planets that have\u00a0conditions conducive to life<\/em>.<\/p>\n
