English: Cosmic Triple Jump. Hannes Alfvén suggested that by scaling laboratory plasma experiment results (assuming an experiment scale of ~10-1 cm) by a factor of 109 makes them applicable to magnetospheric conditions. Another scaling jump of 109 makes the results applicable to galactic conditions, and a third jump of 109 takes us out to the Hubble distance (~1026 cm).
