1908 – 1995
Hannes Alfvén (1908–1995) was a Swedish plasma physicist and Nobel laureate whose work on magnetohydrodynamics fundamentally shaped modern astrophysics and cosmology. He developed the theory of Alfvén waves and pioneered plasma cosmology as a naturalistic alternative to Big Bang models. His cosmological views carried implicit philosophical commitments to causal continuity and skepticism toward singularity-based origins.
