schwit1 shares a report from ScienceAlert: Sound waves fossilized in the maps of
galaxies across the Universe could be interpreted as signs of a Big Bang that
took place 13 billion years earlier than current models suggest. Last year,
theoretical physicist Rajendra Gupta from the University of Ottawa in Canada

Gupta's suggestion isn't even entirely new -- it's loosely based on an idea that
was shown the door nearly a century ago. In the late 1920s, Swiss physicist
Fritz Zwicky wondered if the reddened light of far distant objects was a result
of lost energy, like a marathon runner exhausted by a long journey across the
eons of space. His 'tired light' hypothesis was in competition with the
