Evolution of the Universe
Outline
Why do I talk about this topic? I am
just a nuclear physicist!
What happened during the last 15 x 109
years?
Going back in time: Astronomy
Nuclear physics allows us to describe
stellar nucleosynthesis
The binding energy per nucleon Source
of nuclear energy
Nucleosynthesis in stars forms all elements
heavier than Lithium
Nucleosynthesis
Experimental nuclear physics: Measuring
stellar reaction rates
The evolution of stars
Formation of heavy elements (beyond Iron)
Better techniques/facilities =>Better
info far from stability
Nucleosynthesis is an ongoing process.
Star Formation: 1 x 109 yr after the
Big Bang

the world!
From ABC News The Doomsday Machine!
Will the world survive the first collisions
at RHIC?
