Thomas Gold (1920–2004) was an Austrian-born American astrophysicist and cosmologist at Cornell University, known for bold, often contrarian scientific hypotheses. He co-developed the Steady State theory of the universe with Fred Hoyle and Hermann Bondi, which posits continuous matter creation rather than a singular origin event, and later proposed the abiogenic theory of petroleum formation and the deep hot biosphere hypothesis.
Co-developed the Steady State cosmological model, positing continuous spontaneous matter creation as an alternative to Big Bang cosmology
Correctly predicted that pulsars are rotating neutron stars (1968)
Proposed the abiogenic origin of petroleum, challenging the fossil fuel consensus
Advanced the deep hot biosphere hypothesis, suggesting microbial life exists kilometers underground
Contributed to understanding of lunar surface properties prior to Apollo missions
