• Researchers Find Evidence of Other Universes Lurking in the Cosmic Background

[QUOTE]Just when the search for exoplanets looked like the undisputed fashionable field of study for 2010, the cosmic microwave background (CMB) is stepping to the forefront of astronomy and cosmology. Last month, it was Oxford’s Roger Penrose claiming that he’d found evidence of a cyclical universe in patterns of concentric circles in the CMB, suggesting our universe is just one of many that have come before it (and will come after it). Now, another group of researchers are claiming the CMB contains evidence of other universes that exist concurrently (and outside of) our own. The new evidence, put forth by a group of researchers at University College London, is based upon the model of “eternal inflation,” which is predicated on the idea that our universe is part of a larger and ever-expanding multiverse. Our universe is contained in a kind of cosmic bubble that exists alongside other universes contained in their own bubbles, and in these universes the rules of physics could be far different than in our own. If the eternal inflation theory is correct, it follows that our universe and other universes have likely collided in the past as they violently bounced around the larger multiverse, and those collisions should be evident in the CMB (the cosmic microwave background is a leftover from the Big Bang, and thus is of interest to astronomers and cosmologists for the long historical record it contains – if researchers know what to look for). The University College team went looking for “cosmic bruises” in the CMB that indicate places where other universes collided with our own at some point, and it claims to have found them in data from the Wilkinson Microwave Anisotropy Probe (WMAP), which has been measuring temperature differences in the CMB over the past decade. If indeed the spots are found to be “cosmic bruises,” it would lend a lot of credence to the idea that there are other universes out there that at some point collided with our own. But that’s a big “if.” If the earlier CMB findings by Penrose are any indicator, proving or disproving these sorts of claims rooted in WMAP data is extremely difficult. Fortunately, as Tech Review points out, the ongoing Planck mission should soon provide a much better picture of the CMB to astronomers, allowing them to hopefully prove or disprove some of these cosmological theories. Until then, the time is ripe to attribute statistical anomalies in the vast CMB data set to complex cosmological theories.[/QUOTE] Source: [url]http://www.popsci.com/science/article/2010-12/researchers-find-evidence-other-universes-cosmic-microwave-background[/url]
something tells me that I don't want to know what happens to matter inside our universe when another collides with our own. :ohdear:
:science:
My head...
[QUOTE=STREWTH_99;26683721]something tells me that I don't want to know what happens to matter inside our universe when another collides with our own. :ohdear:[/QUOTE] Nothing. The space between stars is pretty great compared to the size of stars, so when another cluster of stars comes in they most likely fit into the empty spaces. If not, some may collide and be ejected from the galaxy, but the chances us getting ejected is really small. Our galaxy is actually consuming a bunch of small galaxies right now, but it doesn't really affect us. Bah, broke my automerge. Well I feel retarded. When I read his post I thought he said galaxy rather than universe... As far as colliding universes goes...I have no idea.

And even if that were not to happen, I think the barriers of the universes would affect each other in some way. But I don't think anyones ever tried figuring out what the barriers of our universe are like, so I can't be sure.
Does this mean... VideoGame Universes Exist!?
If this were true would just raise more questions. First, it was, what was beyond the universe? Now it will be what is beyond the multiverse?
I wonder if there is a cowboy universe.
Think of the possibilities guys all sorts of universes Pokemon Digimon Halo MAss effect think of the possiblities that family guy multiverse come into mind.
Which means it's certain we will live the exact same life once again. It's like throwing a dice, one day the exact same universe will be created. Since we lose perception of time the moment we die we will instantly be reborn, without the knowledge of our previous lives. I hate to think about it. [editline]value[/editline] But I don't mind because my life is awesome, I got to experience some great shit in the 90's.
It hurt's my brains. But Dang.

[QUOTE=UnidentifiedFlyingTard;26684260]I wonder if there is a cowboy universe.[/QUOTE] Ya'll be gosh darn right there is. There be cattle drivin', horse wrangling, and horseshoe makin' every gosh darn day, partner.
I wonder why the only branch of science that seems content to work almost entirely with speculation is cosmology.
...implications are endless...think beyond the simple OOh cowboy universe, OOH starwars universe the article said [quote]in these universes the rules of physics could be far different than in our own.[/quote] ...the possibilities are endless nothing is impossible.(anymore) [editline]14th December 2010[/editline] if you think about it another universe much less a multiverse is beyond our comprehension for what exists inside of it...

I don't like news like this because it always reminds me of what I will never be able to see in my lifetime. [i]But I still have hope...[/i] :gbsmith:

Hmm, if the other universes have exactly the same laws of physics (which i dont see why they wouldn't), wouldn't that mean there would be a super-symetrical effect and that the other universes would be exact replicas of this one?

Also this could explain dark energy, could be repulsive forces leaking through universal membranes into our universe, which means that universes aren't necessarily isolated and transport across the membranes are possible in some way.

[QUOTE=MisterLANCE;26686372]I could listen to michio Kaku for days and not get bored.[/QUOTE] Kaku tends to over dramatise stuff, to the point of bullshit sometimes, when he said the multiverse was real in the past, that was one of those moments.
[QUOTE=bravehat;26686397]Kaku tends to over dramatise stuff, to the point of bullshit sometimes, when he said the multiverse was real in the past, that was one of those moments.[/QUOTE] I think the main thing he does is simplify things for the general public, and then when someone knowledgeable comes along they point out the problems with what he said. You can't [i]really[/i] simplify something like that to the point that the general public understands and not lose precision. He is really good at explaining things for the more down to earth crowd though.

This is the kind of news I love, it makes me happy yet sad. The universe/multiverse(?) is an amazing, mysterious thing which we will never completely understand in our lifetimes or possibly ever. :frown:
