👉 The epic fluid, also known as the cosmic fluid or interstellar medium, is a vast, diffuse substance that permeates the space between stars within galaxies. It primarily consists of gas (mostly hydrogen and helium) and interstellar dust, with temperatures ranging from a few tens to thousands of degrees Kelvin. This fluid plays a crucial role in the lifecycle of galaxies, acting as the raw material for star formation when it collapses under gravity. It also influences galactic dynamics and can affect the propagation of cosmic rays and magnetic fields throughout the galaxy. Despite its low density, the epic fluid is essential for understanding the structure and evolution of galaxies.
