Physics, Astronomy & Cosmology / Can we detect the death of other universes?

I assume most of you reading this are familiar with the most accepted theories on how our universe will come to it's inevitable ending. The crunch, rip, decay and freeze theories all have logical consistencies and scientists today are still debating amongst these four hypothetical endings. Lots of astrophysicists tend to agree on the big crunch, which is considered to be the reversal of the big bang. While it's still unclear to them in what time frame this would happen, we won't have to worry about it just yet. This theory implies that at some point, all the matter in our universe will return to it's previous state, a singularity. This raises some (maybe obvious) questions to me, which I hope one of you could answer as my interest in the origin of the universe seems to be gradually growing each passing day.
As all matter collapses back into a singularity, I assume a new big bang like event will take place. Fairly recently, a scientist (forgot the name) stated that before the big bang a different universe might have existed before ours. The ending of which resulted in the creation of our current universe. The well known footprint of this event is cosmic microwave background radiation. However, considering our universe is just one amongst infinite others. One would think that like ours, other universes might go through the same hypothetical process. My question is, could this mean that other universes go from singularity to an expanded universe and back? And should this happen, do you think there's any hypothetical way to detect or measure other universes going or having gone through this process?
As you probably might be able to tell, I'm anything but a scientist. But that doesn't mean I don't share your interests. These questions spontaneously popped into my mind and I attempted to find some articles and/or papers mentioning my current dilemma, but with no current success. I hope one of you might be able to explain this or refer me to other sources discussing the topic.
