Big bang Quote by Henning Genz
““The same energy density that we reach today in electron-positron collisions pervaded the entire universe one ten-billionth of a second after the Big Bang. At that time, the universe was the size of our solar system today, and its temperature was one million billion (or 10^15) degrees Celsius. All over space the same processes happened that we observe today in the elecron-positron collisions we just described. The LEP machine in Geneva has permitted the detection of millions of such mini-Big Bang events-truly, it has been a machine for the exploration of the vacuum!””
About This Quote
Source Speech: Talk on LEP at CERN, 1995
The early universe was a tiny, extremely hot region where particle collisions resembled those in modern accelerators, showing that today’s experiments recreate conditions moments after the Big Bang.
In simple terms: Early universe was like a tiny particle collider.
