The little Big Bang

From Little Bangs to the Big Bang

The ‘Little Bangs’ made in particle collider experiments reproduce the conditions in the Big Bang when the age of the Universe was a fraction of a second. It is thought that matter was generated, the structures in the Universe were formed and cold dark matter froze out during this very early epoch when the equation of state of the Universe was dominated by the quark-gluon plasma (QGP). Future L...

Biologists use evolutionary theory to describe the development of life on Earth. The Earth is relatively young by astronomical standards, about 4.6 billion years, and the Universe is even older. It is believed that the Universe w...
