Professor David Lyth (21 June 1940) is a researcher in particle
cosmology at the
University of Lancaster. He has published over 165 papers as well as two books on
early universe cosmology and
cosmological inflation
In physical cosmology, cosmic inflation, cosmological inflation, or just inflation, is a theory of exponential expansion of space in the early universe. The inflationary epoch lasted from seconds after the conjectured Big Bang singularit ...

Research
He is noted for his work in the area of ''inflation model building'' and the ''observational consequences of models of inflation''. In 1997, he discovered the
Lyth bound which relates the tensor-scalar ratio of perturbations in the
CMB
In Big Bang cosmology the cosmic microwave background (CMB, CMBR) is electromagnetic radiation that is a remnant from an early stage of the universe, also known as "relic radiation". The CMB is faint cosmic background radiation filling all spac ...
