Planck era

subject fact

Planck era is followed by hadron era, inflation era 2001-09-27 09:29:58.0
has duration 10^-43 s or the time at which the size of the universe was roughly the Planck length (the time it takes light to travel the Planck length; G h bar / c⁵)^1/2 where G is Newton's constant of gravitation, h bar is Planck's constant, and c is the speed of light has source: Greene, B. 1999 The Elegant Universe, W.W. Norton and Co., New York, 2001-09-27 09:29:57.0
is preceded by Big Bang 2001-09-27 09:29:58.0
has start time 0 s after Big Bang
has definition The Big Bang era, prior to which Einstein's theory of gravitation breaks down and a quantized theory of gravity is needed. Density was so high that gravitational force acted as strongly as the other fundamental forces on the sub-atomic scale. has source: Silk, J. 1990 The Big Bang, W. H. Publishers, New York, 2001-09-27 09:29:57.0
