Their research findings come from the peer-reviewed journal
"Astrophysical Journal Letters," scheduled to be published on March 10,
2003, and have been released in the journal's website.
"If time doesn't become 'fuzzy' beneath a Planck interval, this
discovery will present problems to several astrophysical and
cosmological models, including the Big Bang model of the universe," said
Lieu. "The Big Bang theory supposes that at the instant of creation, the
quantum singularity that became the universe would need to have infinite
density and temperature. To avoid that sticky problem, theorists invoked
the Planck time. They said if the instant of creation was also a quantum
event, when space and time were both blurry, then you don't need
infinite density and temperature at the start of the Big Bang.
"If time moves along like business as usual even at Planck scales,
however, you have to reconcile the Big Bang model with an event that
isn't just off the scale, it's infinite!"
