Each weaver ant can pull on a leaf much harder when in a group than when it works alone. The ants’ sticky feet and coordinated legwork, researchers believe, improve the ants’ collective efficiency—a finding that may provide insights into how to build and coordinate swarms of robots that work together.

Black Hole Singularity; It is the theoretical center of a black hole, predicted by general relativity as a point of infinite density, zero volume, and infinite spacetime curvature. It is where matter is crushed, laws of physics break down, and gravity is absolute, representing a "point of no return" within the event horizon.

Bees generally can’t fly at night, they use the sun as a compass. Even if the sun is behind clouds, bees can infer it’s position using patterns of polarised light So they may sleep in flowers, many blossoms close up at night, creating a warm space

I've broken up some of my lengthy presentations into 1 minute videos so people can be introduced to some credible challenges to Relativity. Cater to those shorter attention spans. And also show main points in favor of a simpler model from Dr. Edward Dowdye's Extinction Shift Principle. Natural Laws Only using elementary math within 3D Euclidean Space. Yielding the same predictions and solutions as Relativity... but NO need for "space-time", NO Time dilation, NO velocity dependent mass, NO Aether, NO 4th Dimension, NO Lorentz Transformations. This flash snippet is to prepare your brain and subconscious for some of the information that will be presented over the next month or so. #Science #math #dowdye #astrophysics

🚨 SCIENTISTS MAY HAVE DISCOVERED “CRYSTALS” OF SPACE AND TIME THAT CAN COLLAPSE INTO TINY BLACK HOLES. Not metaphorically actual mathematical structures hidden inside spacetime itself. Researchers from TU Wien and Goethe University found that during a process called “critical collapse,” spacetime can organize into repeating, crystal-like patterns. If even a small amount of extra energy is added, the entire structure can suddenly collapse into a microscopic black hole. This challenges the usual picture. Most black holes are thought to form from the collapse of massive stars. But this research suggests some could emerge directly from unstable geometric states woven into spacetime itself. What makes the finding even more unusual is how they solved it. The equations became more manageable when the researchers moved into a hypothetical universe with infinite dimensions, then translated the results back into our 4D reality. In other words, they briefly had to leave our universe mathematically to understand it better. The deeper implication is strange: Spacetime may not be a fixed, empty stage. It could behave more like a dynamic structure capable of reorganizing itself into entirely new states, including black holes. What if the fabric of reality is closer to a crystal lattice than an empty void?

A white hole is a hypothetical formation opposite a black hole on the space-time arrow. Scientists have not discovered a single white hole, but in theory there should be at least as many of them as black ones. There is an idea that they can be used to travel enormous distances.

$The very fabric of space-time at the smallest scales is thought to be extremely turbulent and chaotic, described as a frothy sea called quantum foam. This concept, stemming from quantum mechanics and general relativity, suggests that the very nature of space-time is bubbling with tiny wormholes and fluctuations that appear and disappear within fractions of a second. 📷by Johann Rosario$

When a spacecraft leaves Earth, it doesn’t just fire its engines and head straight to its destination. In many missions, especially those going beyond low Earth orbit, there’s a more subtle and elegant strategy at play, one that uses gravity itself as part of the navigation system. This is often called a gravity assist, or a slingshot maneuver. But in the case of missions like #Artemis II, what’s being used is a closely related idea known as a free-return trajectory. At first glance, it might sound simple: the spacecraft goes to the Moon, loops around it, and comes back. But the physics behind it is anything but simple. Instead of relying on continuous propulsion, the spacecraft follows a carefully calculated path through the gravitational field of the Earth–Moon system. It is launched with just the right speed and direction so that, as it approaches the Moon, the Moon’s gravity bends its trajectory. The spacecraft is effectively flung around the Moon, redirected onto a path that naturally brings it back toward Earth. No major engine burn is needed for the return. Small trajectory corrections may still be required, but gravity does the heavy lifting. That’s the key. This kind of trajectory is not just efficient, it’s also safe. If something goes wrong with the spacecraft’s engines or onboard systems, gravity itself ensures the return. It’s an inherent backup plan, built into the trajectory from the very beginning. The same fundamental idea appears in gravity assists used across the Solar System. When a spacecraft flies past a planet, it can gain or lose speed by exchanging momentum with that planet. From the spacecraft’s point of view, it’s as if it has been accelerated without using fuel. In reality, it has borrowed a tiny amount of orbital energy from the planet itself. That’s how missions like Voyager reached the outer planets, and how probes continue to explore regions far beyond what their onboard fuel alone would allow. But there’s an important distinction. An interplanetary gravity assist is typically used to change speed and direction, often increasing the spacecraft’s energy. A free-return trajectory, like the one used in Artemis II, is designed for something more specific: a path that naturally loops back to Earth without requiring additional propulsion. It’s less about gaining energy, and more about shaping a trajectory that guarantees a return. To understand why this works, it helps to stop thinking in straight lines. In space, motion follows curves defined by gravity. The spacecraft is constantly falling, first toward Earth, then toward the Moon, and then back toward Earth again. What looks like a loop is really a continuous free fall through a changing gravitational landscape. This way of navigating space reveals something deeper. We tend to think of engines as the drivers of motion, but once a spacecraft is on its way, gravity does most of the work. The art of spaceflight is not just about thrust. It’s about knowing when not to use it. #GoodLuck #Artemis NASA Artemis

Yes, that was space junk spotted in our bay area skies this evening… video by Jamie Li spotted from San Mateo. As a general rule: meteors, move, much faster and usually end with a flash of light, the orbiting space junk tends to move more slowly and can be easily followed across the sky as the materials burn up on reentry. 9/25/2025 NBC Bay Area

Some microorganisms may have little trouble surviving being blasted into space on planetary debris when an asteroid hits. That finding comes from subjecting a particularly hardy species of desert bacteria to a simulation of the immense forces produced by an asteroid collision. The research lends support to the idea that life jettisoned off world could spread to and seed new worlds by clinging to space rocks. Learn more: News from Science

Physical AI won't just be limited to controlling robots and spatial computing; it will usher in a new era of machine design. You will be able to "vibe design" a robot - or a part of a robot - or a machine that manufactures robot parts - using high-level specifications such as preferred architecture, material constraints, cost constraints, supply chain and geographic limitations and scalability. AI will provide preliminary designs that human experts can tweak and tune, corresponding supplier catalogs, and machining options. It will also project the talent and CAPEX required at various phases of hardware development.

Like a stadium full of sports fans doing the wave, neurons coordinate their electrical signals in rhythmic patterns that sweep across the cortex, the brain’s outermost layer. Recent studies in humans and animals have shown these patterns, called traveling waves, can take on complex shapes, among them a rotating spiral that has been observed during deep sleep, memory retrieval, and other brain processes. A new study has now captured the fast-spinning waves spanning whole brains, offering clues to how they’re organized and what they might do. Learn more: News from Science
