Trying to refactor the flock evolution so that the entities can continuously grow with new parameters for the size and the intervall of sizes that are prey.

This image of the Helix Nebula from the ground-based Visible and Infrared Telescope for Astronomy (left) shows the full view of the planetary nebula, with boxes highlighting Webb’s field of view (right). The new image of a portion of the Helix Nebula from NASA’s James Webb Space Telescope highlights comet-like knots, fierce stellar winds, and layers of gas shed off by a dying star interacting with its surrounding environment.

A breathtaking look at a dying star. This new image of the Helix Nebula is just in from JWST.
We've never seen this level of detail, as the star's remains stream back out to interstellar space. Our Sun will look something like this 7 billion years from now. 🧪🔭

Gravity is the curvature of spacetime. So, how curved is the spacetime we are in right now?
Let’s start by looking at the effect of curvature in a very simple situation. Two meridians on a sphere, like the red and blue ones in the diagram, will come together and move apart …
