Vacuum Can Be Measured

Vacuum Can Be Measured

Russian physicists claimed they had successfully measured the essence of emptiness.
      
      Frankly speaking, what we call vacuum is not just an empty space its a complex environment full of interstellar plasma. Parameters of space gas, such as density, speed, magnetic field and others, change randomly at any measurement scales.
      
      Russian physicists succeeded in estimating so-called outer scale of turbulence (the length scale at which the structure function for Kolmogorov turbulence breaks down at large scales is called the outer scale of turbulence) and found it to be 0.03 parsec.
      
      However, researchers still fail to explain these changes, they can only measure turbulence spectrum by observing changes in parameters of radio waves, piercing interstellar plasma. Pulsars radio waves are powerful enough to be easily registered on Earth by means of radio telescopes.
