EVOLUTION OF MATTER
|
The Universe from the Big Bang to the future
Theories of the birth of the Universe, the formation of the first galaxies, stars and black holes, and their evolution to the present will be presented and discussed in the light of the latest observations.
Most of the Universe seems to consist of mysterious dark matter and even more mysterious dark energy. A major challenge of present cosmological research is to understand the origin and roles of these invisible players in cosmic evolution, and how they determine the structure of the visible Universe.
As in living organisms, the evolution of the Universe is determined by a continuous feedback from cosmological to star-size structures. Gamma-ray bursts, detected throughout the Universe at rates of about one a day and lasting form a few milliseconds to several minutes, are incredibly violent signals of other mysterious events - perhaps the merger of neutron stars, the collapse of a massive star or neutron star-black hole binary. Metals, essential constituents of life on Earth, are ejected by exploding stars at the end of their lifetimes and provide raw material for the next generation of stars. New telescopes in space and on Earth are revealing ever more about the most distant and oldest parts of Universe and are scanning near stars for other solar systems.
