I was watching a program which were comparing various Big Bang theories
against each other. In it, they said one way to falsify Inflation vs.
Cyclic Universe theories is that a Cyclic Universe will *not* produce
gravity waves. Does anybody know why this would be the case? One would
think that whatever mechanism lead to the BB, would always cause a lot of
gravity ripples.
I found some info on it, but it doesn't really explain what leads to this
conclusion:
The one possible test that they point to that could distinguish the
inflation and cyclic scenarios is the expected more sensitive measurement
in coming years of a possible B-mode polarization signal due to gravity
waves in the CMB. They claim that inflation predicts a significant amount
of B-mode polarization, whereas the cyclic model doesn’t.

"That's a valid point. But physics is not a story. One has to be
cognizant of the difference between Reality and the stories within
Reality about Reality.
Example: Say for the sake of brainstorming, we as humans lost all
records of the past. Lost all the books and symbols that the past has
impressed upon us. Don't ask how, just assume so.
Now, what would happen? It is highly unlikely that the stories of the
Religions of the world would be recreated the same as they exist
today. The chances are nearly zero. On the otherhand, the laws of
physics would be exactly the same when rediscovered. Only the names
and faces of the discoverers would change.
In this objective sense, physics is not a story. While everything else
is. The laws of physics are independent of the cultural and
traditional biases, including the religious ones, of any society
contemplating this entity called Physics."
