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

General relativity 🤝 neural fields This simulation of a black hole is coming from our neural networks 🚀 We introduce Einstein Fields, a compact NN representation for 4D numerical relativity. EinFields are designed to handle the tensorial properties of GR and its derivatives.

Using a novel dome-shaped structural design, researchers in Science present a chemically diverse collection of aerogels that remain elastic and mechanically intact under extreme temperatures. The findings open the door for the fabrication of new aerogel materials suited to extreme environments.

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

This animation shows the binary black hole system of OJ 287. Every 12 years, the smaller black hole punches through the accretion disk of the larger black hole and results in a flash of light that is over a trillion times brighter than the sun. By KFRMAN

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.

🚨 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?

Light carrying chip patterns through a lithography system can heat the system’s optics and deform the patterns. With wavefront optimization – computational lithography tools to correct chip patterns just before they reach the wafer – we ensure patterns appear exactly as intended.

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
