The plasma behaves like a weather system in terms of being incredibly hard to predict using conventional techniques.
Recent breakthroughs, however, have brought the concept closer to reality.
The milestonewashailedas one of the most impressive scientific feats of the 21st century.

At Pulsar Fusion, hopes have been further buoyed bynew advances inAI.
Themachine learning simulations will guide the rocket engines design.
