The discovery that could rewrite physics

Hi everyone,

What do you think?

-> The discovery that could rewrite physics
On March 17, 2014, a group of physicists announced a thrilling discovery: the “smoking gun” data for the idea of an inflationary universe, a clue to the Big Bang. For non-physicists, what does it mean? TED asked Allan Adams to briefly explain the results, in this improvised talk illustrated by Randall Munroe of xkcd.

Yes it is a very important discovery but It is very difficult for me to fully understand it.

Hi Gérard, everyone !
I have been reading all over again that discovery because it is awfully important and interesting. There in fact two discoveries : the universe is expanding and gravitational waves exist.
Gravitational waves are a feature of the theories of relativity and cosmic inflation a feature of quantum mechanics.
They think they can reconcile the two incompatible  theories.

This suggests the cosmos is constantly giving birth to parallel universes

What do you think ? Have I misunderstood the whole thing ?
