What Happened Before the Big Bang?

   A few centuries past, people thought the Universe was static. Then we invented better and better telescopes and finally eccentric astronomer Edwin Hubble found that star cities called galaxies exist, that everything out there is moving, and that galaxies are dispersing.

   So cosmic theory went from static to expansive with the logical probability that expansion ought to eventually slow down under gravitational attraction and then contract all the way back to a singularity that might again expand into a new Universe.

   But then we discovered that the Universal rate of expansion is not slowing at all but is instead accelerating under some strange unknown repulsive force we're calling dark energy, posing the prospect that the Universe we know and love is doomed to eventually cool, with star and planet formation slowing and eventually ceasing, and the whole grand show dying.

   We know our lives can't last forever and neither can our solar system because our private star only has a finite fuel supply and is already in middle age, having burned for 4.5 billion of our years. But to think the whole Universe also has a finite life with only utter darkness before and after is supremely depressing. It has been some 13.5 billion years since the Big Bang and maybe the Universe is middle aged or more, too.

   There has been a theory floating around that ours is just one of multiple parallel universes, but this is intuitively improbable and unsupported by any evidence whatever, lacking even credible theoretical support from various disciplines such as astronomy, mathematics, and physics.

   Leaving us with a profound question. We think we know the sad fate of our Universe, but what happened before the big bang birthed it?

   Some highly respected scientists believe they have a good idea.

   Sir Roger Penrose is a genius Oxford physicist, mathematician, and philosopher. He and several equally bright colleagues from various disciplines have developed a promising theory they call Conformable Cyclic Cosmology or CCC, which suggests there has been and will continue to be a succession of Universes, one after the other, each growing from a singularity and eventually dissipating. They call the whole process from birth to death an eon. Their theory says it's possible there has been eon after eon in the past before ours and there will be still more eons in never ending succession after ours is gone. There is both mathematical and geometric support for this theory, and there may even be hard evidence for it in physics. Part of the theory says that effects lingering from the previous eon to ours should be detectable.

   In 2002, a physics experiment called LIGO was set up in Hanford, Washington, and Livingston, Louisiana. to detect gravitational waves for fundamental studies. That has been a success. They found those waves with much deserved exuberant celebration. The experiment, however, also picked up signals thought to be mere noise, and this data was summarily discarded as unhelpful. But Sir Penrose suggested they take a closer look at the noise. The Universe has been thoroughly mapped by various means over the years and is known to have a filamentary structure of stars connecting clusters of galaxies. Our own Milky Way galaxy lives within a cluster called the Local Group. Here and there within this Universal structure there are odd patches empty of stars but filled with a mysterious magnetism. Sir Penrose suggests those areas may be leftover ingredients from the previous eon cycle.

   And that in turn suggests the good news that life itself may well regenerate and endure.
