So what do we call all the space outside our universe? 

Our universe may show bruises from smacking four other universes  DVICE  Universe shows bruising from smacking up agansint other universes. 

REALITY CHECK
So what do we call all the space outside our universe? 

DILDs: A Lot


Fascinating idea. So I guess the idea is that another universe shortly overlaps with our universe, creating a concentration of background radiation. I suppose that would look like a convex disk. 


Lost count of how many lucid dreams I've had

Uhm, that article is on SyFy. Anyways, the talk about other universes outside of space bumping into each other makes no sense, because the universe is space. There is no space outside of space. derp? 

I assume you mean that the comment made no sense yes? 

I could be wrong but this is probably a brane world type of idea. So our 'universe' would be a 3brane in a higher dimensional space. Another universe would be another 3brane, also in the higher dimensional space. So they could 'bump' into each other. That's how you have 'space outside of space'. Just more space. The collisions would affect the distribution of matter leading to large 'bald patches' in our 3brane where there was very little matter and hence things like stars and stuff. Apparently, one was successfuly predicted and later observed a few years ago.

This is superconfusing, I was told the universe is a selfcontained space, which could even be infinite, and questions of expansion 'into' something are meaningless.

hmmmm.... the article is shit btw. Don't bother arsing yourself. 

Empty space still requires spacetime/dimensions. 

All space within our universe has stuff in it. There isn't actually any 'empty' space within our own universe, so when we say there is nothing outside our universe, that nothing is a lot different than the seemingly nothing we have within it. And when we say there is nothing outside our universe, that isn't including the theories of other universes that might be outside our own. 

How is there not empty space in our universe? Everywhere there is not stars, there is space. Tonnes of it. 99% of "solid" objects is also space. 

Space is not nothing by any means. For a start is has structure: it can be curved. Secondly, it ain't empty: space is continually frothing with quantum fluctuations. The 'Nothing' part of the 'Everything and Nothing' BBC series covers this if you're interested. 

I'll check it out. 

Most articles by reporters are shit ... As an aside it strikes me as weird that many people who have no problem rejecting mainstream reporting as incompetent suddenly are willing to judge the credibility, humility, and motives of scientists based on an even lower standard of journalism.

I understand the mathematics behind this, but I fail to see how to prove those bruises can be from other universes. There is so much of that level of physics that is yet to be understood, they could very easily be bruises cause by other things, such as concentrations of negative energy. Negative energy is something still poorly understood. 

You.... understand the mathematics? 

This is the guy who thinks that Mercury pulls on the Sun harder than Jupiter because 'Mercury is much closer and gravity decreases exponentially with distance', and doesn't know what an integral is. So I'm sceptical. 

I understand the mathematical concept, I've never look at the math for this article. If the universe is truly just a set of vibrations in much larger branes, I certainly understand how two universes even coming close to each other can create bruises. The mathematics of vibrations interrupting other vibrations is elementary, in MTheory, you would just have to expand that into 11 dimensions, a tedious task, but possible for someone with the time.

Ehh I just distinctly remember in chat when you said you never understood what Riemann sums were and I thought 'lolwat'. Not trying to be rude, I just find it unlikely that you couldn't get that but knew the mathematics of Mtheory... all you're really giving now is a dubious heuristic, that's not the same thing as understanding the mathematics.
