Heidelberg physicist develops a new theoretical model in
which the Big Bang stretches into the infinite past
Did the universe begin with a hot Big Bang or did it slowly
thaw from an extremely cold and almost static state? Prof. Dr. Christof
Wetterich, a physicist at Heidelberg University, has developed a theoretical
model that complements the nearly 100-year-old conventional model of cosmic
expansion. According to Wetterich’s theory, the Big Bang did not occur 13.8
billion years ago – instead, the birth of the universe stretches into the
infinite past. This view holds that the masses of all particles constantly
increase. The scientist explains that instead of expanding, the universe is
shrinking over extended periods of time.
