Evidence hints at multiple universes

Edit: A side note; there's more to look forward too

If collisions with other universes did indeed create these patches, they should have left other calling cards in the CMB, such as a telltale signature in the orientation, or polarisation, of CMB photons. The European Space Agency's Planck satellite, which launched in 2009, should be able to detect these signs. Its first full maps of the sky are expected in 2012.

Wow. It is so popularized with all the talk of bubbles and a sea of space time and so on, that I have no idea what they are actually saying.

The best way I can think to explain it, is a sort of swiss cheese theory (the theorist analogy not mine), where space/time/the vacuum of space is sort of everywhere, and is constantly expanding.... The quantum event's that triggered the "big bang" i.e. an "explosion" of energy/matter/anti-matter and forces causes a "bubble" to form inside the "cheese"(space). It expands in all directions equally.
The idea is that, as with swiss cheese.... you don't usually get one bubble >.<. So wherever the quantum effects are just right that are required to "ignite" the big bang creates a new "universe"....
It's hard to prove as distances are so great and things beyond our visible horizon are moving fast enough away that we will never catch a glimpse let alone a sample >.<.

Anyway I guess someone theorised if this multiverse theory had some validity you might be able to see where other universes "bubbles" (essentially a sphere in space time containing localised matter/energy etc. that spawned from a similar event as ours.) have interacted with ours early on. I guess the bubble implies the outward flow of energy that happened during inflation as opposed to matter from other universes colliding with ours...

BTW
I have no credentials in physics, this is just stuff I've picked up from reading science web sites, documentaries, books etc. So take what I say with a grain of salt. I THINK that's how the current theories of the universe(s) and their origins are leading away from our big bang being the centre of everything.... just like earth wasn't the centre of everything ^.^.... Just another ordinary planet, orbiting another ordinary star, orbiting another ordinary Super Massive Black Hole in the centre of another ordinary galaxy which is part of an ordinary galactic cluster (or local group) which just so happens to be in just another ordinary universe...

Hell the closer and more precise we look, the more we find as we go smaller and smaller and smaller.... quarks, gluons etc. I don't see why the same wouldn't necessarily apply in the opposite direction... The further out we look, the better equipment we use to examine how far we can see, the more we reveal about our universe, the greater cosmos, and everything within....

I love science.

Sorry I don't have better sources... Please feel free to correct me if I've miss interpreted or simply stated something incorrectly.

I don't buy it. There might be other reasons why CMB could be preferentialy polarized in one direction in oposite to others. We shouldn't get ahead of ourselves.

This isn't the sole piece of evidence, there's many other things that conflict with the standard model of the big bang theory and are leading people to wonder if we aren't but one of many "bubble" universes..... but I think I'll stop before I step too far out of my area of knowledge and into someone else's area of expertise. Would prefer to hear from one of the many noted physicists on these boards.

Meh, these papers come and go. Last month, there was a paper from Gurzadyan and Penrose where they stated that patterns in the CMB hint at a cyclic universe. So who's right?

As Sarah Kavassalis said on her blog, finding patterns in the CMB is a bit like finding bible codes: there's only one CMB, so even if the fluctuations are purely random, you can find any pattern you want if you try hard enough. Extraordinary claims require extraordinary evidence, and they don't have it (yet).
