Who Do You Want To Squeeze Cute Things?
Observing a clumsy kitten may evoke a sense of overwhelming adorableness, leading you to desire petting its soft fur and showering it with affectionate gestures. However, you may also experience a conflicting urge to squeeze or even nibble the kitten, which can be puzzling and alarming. This phenomenon, known as "cute aggression," is surprisingly prevalent, affecting approximately half of all adults. To delve into this peculiar behavior, let's explore the concept of cuteness.

Gravity vs Pressure
Ladies and gentlemen, get ready to witness the grandest showdown in the making of the universe. Brace yourselves for the epic clash of powers in the event known as the Big Bang! In one corner, we have the mighty force that draws all matter together, reaching infinitely far—the one and only gravity! And in the opposite corner, our formidable contender possesses the remarkable strength to repel matter with great vigor. When faced with challenges, this fighter only grows stronger—give it up for pressure! Over the next several hundred thousand years, these two contenders will engage in a cosmic wrestling match that will determine the destiny of the universe. Yes, folks, the ripple effects of this monumental battle will shape the very fabric of the universe we inhabit today. But what is at stake in this cosmic showdown? The answers will unfold as we witness the explosive arrival of the Big Bang! Let's zoom in for a thrilling play-by-play commentary.

How Many Universes Are There?
During long plane flights, I often find myself gazing at the vast mountains and deserts, trying to comprehend the immense size of our Earth. In those moments, I am reminded of the sun, an object we see daily, which could contain one million Earths within it. The sun's enormity is staggering, yet in the grand scheme, it is just one of around 400 billion stars in the Milky Way galaxy. On clear nights, we can observe the Milky Way as a pale, white mist stretching across the sky. The magnitude grows even more astonishing when we consider that there are approximately 100 billion detectable galaxies in the universe. If each star were akin to a grain of sand, the Milky Way alone could fill a 30-foot by 30-foot stretch of beach, three feet deep with sand. Such is the scale of the cosmos that the entire Earth cannot represent the multitude of stars it holds. A beach symbolizing all the stars in the universe would extend for hundreds of millions of miles.

Why Can’t We See Evidence of Alien Life?
Somewhere amidst the vast expanse of the universe, it is highly probable that countless other planets are teeming with life. Yet, why do we lack any tangible evidence of its existence? This intriguing question, famously posed by Enrico Fermi in 1950 as “Where is everybody?”, continues to baffle us. While some conspiracy theorists claim that UFO sightings are frequent but covered up, their arguments lack convincing proof. Nevertheless, the mystery remains. Over the past year, the Kepler space observatory has discovered hundreds of planets orbiting nearby stars. Extrapolating this data suggests that there could be approximately half a trillion planets within our own galaxy alone. Even if just one in every 10,000 harbors conditions suitable for life, we are left with 50 million potential life-supporting planets in the Milky Way. So, here lies the enigma: Earth formed approximately 9 billion years after the Big Bang. Countless other planets in our galaxy likely formed earlier, allowing life to potentially emerge billions, if not millions, of years before it did on Earth. If even a few of these planets nurtured intelligent life and developed advanced technologies, those technologies would have had ample time to evolve over millions of years. Just observing the rapid acceleration of technology within the past century on Earth exemplifies this potential. In the span of millions of years, an intelligent extraterrestrial civilization could have conceivably spread throughout the galaxy, creating colossal energy-harvesting structures, fleets of space-faring vessels, or awe-inspiring celestial artwork. At the very least, one would expect them to reveal their presence through deliberate or unintentional electromagnetic signals. Yet, we lack compelling evidence of any such phenomena. Why? Numerous possibilities exist, including some rather somber ones. It is plausible that a single superintelligent civilization has seized control of the galaxy, imposing strict radio silence out of fear of potential competitors. They might lie dormant, prepared to annihilate any perceived threats. Alternatively, perhaps intelligence capable of creating sophisticated technology is exceedingly rare—a phenomenon that has only occurred once on Earth in its 4-billion-year history. It could be argued that we were exceptionally fortunate. Another possibility is that civilizations inherently carry the seeds of their own destruction due to their inability to responsibly manage the technologies they create. Nonetheless, several more optimistic explanations can be considered. Firstly, our search efforts might be insufficient, with relatively limited resources allocated to the pursuit of answers. Only a small fraction of the stars in our galaxy have been meticulously examined for intriguing signals. Furthermore, our approach might be misguided. As civilizations progress, they may discover communication technologies far more advanced and practical than electromagnetic waves. Conceivably, the action takes place within the enigmatic realms of recently discovered dark matter or dark energy, which account for the majority of the universe’s mass. Alternatively, our focus might be misaligned in terms of scale. Intelligent civilizations may realize that life’s ultimate essence lies in complex patterns of information, interacting harmoniously but more efficiently on a smaller scale. Just as clunky stereo systems have given way to elegant, compact iPods on Earth, intelligent life may have downscaled itself to microscopic proportions, minimizing its impact on the environment. The solar system might be teeming with aliens, yet our perception fails to detect them. An even more audacious idea suggests that the very ideas within our minds could represent a form of alien life. Admittedly, this thought ventures into the realm of wild speculation. Nevertheless, it is intriguing to consider that ideas possess a life of their own, often outliving their creators. Perhaps biological life is merely a transient phase. Within the next 15 years, real spectroscopic information from promising nearby planets may shed light on their potential habitability. Meanwhile, the
