Event Horizon II (The Beginning According to Planck)
On 21st March 2013 the European Space Agency released a map with details of the universe’s ancient light. This map was assembled with data collected by Planck, a space telescope that measures Cosmic Microwave Background and it shows that the universe is 80 million years older than previously thought.
This map fits with the standard model of cosmology – the idea that the Universe started in a hot, dense state in an incredibly small space. Data collected by Planck also supports a theory known as inflation, which postulates that in the very first moments of its existence the Universe opened up in an exponential manner.
Theory says that 380,000 years after the Big Bang, matter and light “decoupled”, matter went on to form stars and galaxies; the light spread out and cooled. We cannot measure the singularity before the Big Bang, we can only go as far back as a trillionth of a trillionth of a second after that moment.
