Our universe is big. It’s huge. It’s massive. And it’s expanding. But expanding into what? Does our universe resemble a balloon, expanding out into some grander space? Questions like this may seem simple, but they have s
In some ways, TREE(3) mirrors the boundaries of the universe itself. Just as there are cosmic horizons we cannot cross—where galaxies fade beyond sight, where information from black holes is lost forever—there are also i
But the effects of time dilation are still visible today. When we look at distant galaxies, we’re seeing them as they were billions of years ago—closer to the time of the Big Bang. The light we observe from these galaxie
But the thing is that our brain is made up of a complex network of nearly 100 billion neurons that form 100 trillion neural connections. These neurons are organized into networks of nodes, filaments, and clusters that sh
Cosmic voids represent the most enduring time capsules in the cosmos, remaining largely unchanged over billions of years. Defined by their sparse matter content, these voids provide a pristine and unparalleled environmen
Let’s begin from the beginning, or at least what scientists tell us is the beginning. Around 13.8 billion years ago, all of existence—the universe, space, time, and every speck of matter—erupted from a single, infinitely
Physics has reached a point where many things aren’t directly measurable. If we create a theory that explains everything in the observable universe and requires a multiverse, some scientists would accept that we may neve
Over time, through various experiments, we've discovered something interesting about tiny particles called quanta. These particles act like both waves and particles at the same time, and what we see depends on how we cho
Kardashev’s question can be asked in another way: What are the universal steps in a civilization’s journey toward advanced technology? The idea is that most, if not all, civilizations would go through certain stages as t
To understand how the Universe creates intelligent life, we need to consider two things. First, we must understand the steps that led to our own existence. Second, we need to explore how intelligence could arise in diffe
Seeing the universe as one quantum object changes how we think about reality. It suggests that the separations we see are just an illusion—a useful one for everyday life, but an illusion nonetheless. At the deepest level
Among the fundamental forces, gravity stands out as an outlier, being significantly weaker than electromagnetism, the strong nuclear force, and the weak nuclear force. This difference in strength isn't just slight; it's
Even though the universe is teeming with virtual particles, it doesn't entirely dismiss the concept of nothingness. Firstly, there's the mystery of the nothingness preceding the Big Bang, a realm we are yet to comprehend
Most people, when they envision chaos, see a myriad of phenomena intersecting and overlapping in berserk order. It is hard to envision chaos in a world that seemingly exudes order, but more often than not, chaos is found
Time is an illusion, a concept our brains create to make sense of the world. At its core, time might not even exist in the way we think it does. It’s a construct that helps us track changes and events, but in the deepest
Although the void appears completely dark to our eyes, solving its mysteries could paradoxically shine a light on outstanding problems in our theories of the universe’s evolution, structure, and perhaps even the nature o
The notion that the universe around us might be an elaborate illusion stems from knowledge's mediated nature. We perceive things not as they are in themselves, but as they appear to us through our senses and cognitive ab
Reality, if you want to call it that, isn’t some objective existence beyond what’s measurable or observable. In physics, describing what is observable and measurable as accurately and completely as possible is our highes
Even in completely empty space, with no external fields present, There's still some amount of non-zero field energy existing in any region. If quantum fields are everywhere, according to Heisenberg's uncertainty principl
When time reaches its limits, scientists call those moments "singularities." These can mark the start or end of time itself. The most famous singularity is the big bang, which happened around 13.7 billion years ago, kick
