👉 The q-fluid, also known as the Q fluid or Q liquid, is a theoretical model proposed to describe the behavior of highly compressible fluids under extreme conditions, such as those found in astrophysical environments like neutron stars or during supernova explosions. Unlike conventional fluids, the q-fluid exhibits unique properties where its viscosity decreases dramatically with increasing pressure, a behavior attributed to the formation of a highly ordered quantum state. This state reduces internal friction, allowing the fluid to flow with minimal resistance. The concept of q-fluid is crucial in understanding phenomena where traditional fluid dynamics fail, providing insights into the internal structure and dynamics of ultra-dense matter in extreme cosmic settings.
