James Peebles¡¯s insights into physical cosmology have enriched the entire field of research
and laid a foundation for the transformation of cosmology over the last fifty years, from speculation to science.
His theoretical framework, developed since the mid-1960s, is the basis of our contemporary ideas about the universe.

The Big Bang model describes the universe from its very first moments, almost 14 billion years ago,
when it was extremely hot and dense. Since then, the universe has been expanding, becoming larger and colder.
Barely 400,000 years after the Big Bang, the universe became transparent and light rays were able to travel through space.
Even today, this ancient radiation is all around us and, coded into it, many of the universe¡¯s secrets are hiding.
Using his theoretical tools and calculations, James Peebles was able to interpret these traces
from the infancy of the universe and discover new physical processes.

The results showed us a universe in which just five percent of its content is known, the matter which constitutes
stars, planets, trees – and us. The rest, 95 percent, is unknown dark matter and dark energy.
This is a mystery and a challenge to modern physics.
