How large is the universe in Planck lengths?
Easy, I’ll let you work it out. The Planck length is 10−33
centimeters.
A light year is a years’ worth of seconds (about π
centimeters per second.
Our observable universe particle horizon is 45 billion light-years.
So how many orders of magnitude, 33, plus 7.5, plus 10.5, plus 10.6 is ….
It turns out to be a rather interesting number since it may relate to the 120 or so orders of magnitude by which dark energy is much weaker than the straightforward particle physics first estimate. Take the square root of 10120.
It
is a curious cosmic coincidence that may have something to do with the
fact that space is quantized, tiled, and in fact an emergent property of
quantum entanglement of particles and fields.
