I believe that it is so funny we as a species are so valiant and confident that mere physics, a man creation, will be something that will question how something as complex as our universe works. I think it's safe to say that what we think we know in regards to anything is far from what the actual truth is considering that we barely got to the moon!

Arrogance, greed and political correctness will ensure that our existence will be extinct. I think that something such as a super-massive black hole from another universe is a very practical idea, considering we have only mere human instruments that can barely detect anything within our own galaxy. We live in in such a tiny bubble and focus all of our time trying to bully and control each other that something as simple as a tiny black hole that we'd NEVER be able to detect could lurking within a distance and destroy this entire solar system and there's not a thing we could do about it.

We're all left overs from what ever happened and because of that we all have the right to speculate. I think if people spent more time trying to figure out plausibility rather than pointing out flaws especially in the scientific community, we'd probably have a better idea about a few things...

The space-times are not the same.

 

 

 

It would also be very complicated, if at all possible. Matching the physics in both space-times is going to be hard.

 

 

 

A duality would state that the physics is identical in both space-times. This is not the case, or at least it is not clear. However, like I said you can use the same global techniques to analyse things. I don't see that is a duality.

 

 

 

They say that under reasonable assumptions (quite technical, but reasonable) that gravitational collapse in classical general relativity always leads to the creation of a singularity. In "reverse" they state that the expansion of the universe must have started from a singularity, again in the context of general relativity. I don't think they state that these are the only singularities as such. There is a conjecture that naked singularities cannot exist, again with some technical assumptions. However, I do not think this is really proved.

 

 

 

But the universe is under no obligation to be "simple". Occam's razor will only help when we have two equally valid explanations. Even then, experiments and observation trump and simplicity.
