Modeling Electrical Arcing in Vacuum (IMAGE) American Physical Society Caption Even in a vacuum, voltages can literally tear metal apart. Current research is using molecular dynamics to show what happens at the atomic level when material is damaged by arcing in vacuum. Credit J. Norem, Z. Insepov, Th. Proslier, D. Huang, S.
