Is gravity a cosmic fluid? Part 1: The weight of history By Marcelo Fontinele "What goes up, must come down." Since we were children, we have heard this phrase that simply expresses one of nature's most fundamental phenomena: gravity. However, behind this apparent obviousness lies one of the deepest mysteries of the universe. Throughout the history of science, we have tried to decipher its nature: Is it a force? A curvature? Or perhaps something even more fundamental, like a fluid that permeates the cosmos? In this first part, we revisit the visions of two geniuses: Isaac Newton and Albert Einstein. Understanding them is essential to taking the next step toward a new interpretation. Newton: Gravity as a Universal Force of Attraction Isaac Newton, in his work Philosophiæ Naturalis Principia Mathematica (1687), postulated the Law of Universal Gravitation , formulated as: $$F = G \cdot \frac{m_1 m_...
The wisdom of the cycle: Learning to breathe with the seasons of life We live in a world that is obsessed with a perpetual Summer. We are told to be "on" 24/7, to be constantly blooming, and to keep our productivity levels at a permanent high. But nature, the greatest teacher we have, tells a completely different story. If a tree tried to bloom all year round, it would eventually die of exhaustion. Why do we think we are any different? The courage of the autumn (The release) Autumn is perhaps the most visual lesson in vulnerability. It’s the moment the tree decides that keeping its leaves is more costly than letting them go. In our lives, Autumn is about auditing our energy . What habits are you dragging along that no longer serve you? What version of yourself are you outgrowing? Letting go isn't a sign of weakness; it’s an act of strategic survival. You are clearing space for what’s next. The sacred winter (The subterranean growth) This is the hardest stage for most of u...
