That's tantalising, and I never considered it before. I just supposed they would come into contact to annihilate. Do they actually annihilate from a distance, or does one tunnel into the other, or something?

That is what I suspected. So much for the topic header. Next... Which parts of quantum theory specifically led to entanglement and how? What specifically convinced these physicists that it was a real phenomenon?

In 1935 Albert Einstein, Boris Podolsky, Nathan Rosen, and Erwin Schrödinger introduced the notion of quantum entanglement. What prompted that notion and what justified their belief it was a real phenomenon?

So you are as sceptical as me about Susskind's claim for future Boltzmann structures in a universe with accelerated expansion?

This is ridiculous. I should have titled the original post 'All matter bounces off event horizons and returns'. And subtitled it 'There are no black holes, only white holes: official' It's ridiculous. How can it stand? It's unphysical.

I certainly have trouble grasping that. It is quite counterintuitive to me, with no physics training. A positive cosmological constant means zero density everywhere eventually, no? Could you post a link or two that would explain why it's a finite system? 'are now' - sure, granted; it would be...

@timmdeeg Thanks for that very interesting link. The author mentions Susskind, contextualising: "... even if the universe consists of more or less empty space at a temperature of 10^-30 kelvin, random fluctuations will occaisionally [sic] create atoms, molecules... and even solar systems and...

Also, it's General Relativity that explains why things approach horizons asymptotically.

First, apologies for giving the wrong link in my original post. It's http://www.cornell.edu/video/leonard-susskind-1-boltzmann-and-the-arrow-of-time "Boltzmann and the Arrow of Time: A Recent Perspective", a talk by Leonard Susskind. Or - the same talk for Webkit browsers if the first link...

Given enough time Boltzmann freak structures will appear, assembled from drifting matter, in the maximum-entropy universe if it is static, I.E. not expanding to eventually sweep all matter into the far horizon. In a lecture...
