The Big Bang Makes Waves

Astronomers announced Monday that they had discovered what may be one of the greatest triumphs in modern day observational astronomy – ripples in the fabric of space-time that are echoes of the massive expansion of the universe that took place just after the Big Bang some 14 billion years ago.  Predicted by Albert Einstein nearly a century ago, the discovery of ripples, called gravitational waves, would provide evidence how the universe began and evolved into the countless galaxies and stars, dust, and vast stretches of empty space that make up the known universe.


Confirming inflation would mean that the universe we see, extending 14 billion light-years in space with its hundreds of billions of galaxies, is only an infinitesimal patch in a larger cosmos whose extent, architecture and fate are unknowable. Moreover, beyond our own universe there might be an endless number of other universes bubbling into frothy eternity, like a pot of pasta water boiling over.
