Story summary

A team from Keio University, led by Tatsuya Kotani and Professor Tomoharu Oka, confirmed a key Big Bang prediction by measuring the cosmic microwave background temperature at 5.13 degrees above absolute zero.
The measurement derives from light traveling seven billion years and is the most precise for that period.
The findings reinforce the standard model of cosmological evolution and align closely with theoretical predictions, enhancing understanding of the Universe's history.
