Thurisaz Posted October 24, 2013 Share Posted October 24, 2013 It would be cool if that was true, but I'm very skeptical; how can we ever be reasonably sure of things outside our universe? They would be as far outside our direct range of observation and verification as the fairy tale gawd of da babble. Besides, what would "outside" mean beyond our own spacetime anyway?

What if scientists have found evidence of more than one universe? Opinons? Ummm... I can't successfully open the first link, HZ. Can you cut n' paste the relevant info or try something else please? Thanks. . . . Peter Woit's blog, "Not Even Wrong" is where he criticizes the... lack ...of hard evidence for String theory. When String theory (which, as best as I know, has NO evidence for it) is linked with Cosmic Inflationary theory (which has several strong lines of evidence to support it) the result is a Multiverse. So, if hard evidence of a Multiverse were found, this would be a strong indicator that String theory is correct. This is why Woit focuses on the Planck data not supporting Dark Flow. Because he's an arch-critic of String theory. One strike against the Multiverse and String theory. However, the CMB Cold Spot, has been confirmed by Planck as not being an anomalous artifact in the data gathered by it's predecessor, the WMAP satellite. The spot appears to be real (though some scientists dispute this), but the claim that it's an imprint made by another universe 'bumping' into ours has not been verified. http://en.wikipedia.org/wiki/CMB_cold_spot http://sci.esa.int/science-e-media/img/67/Planck_anomalies_Bianchi_on_CMB_orig.jpg (The Cold Spot is ringed in white in the lower right quadrant of this Planck all-sky map.) Many different explanations have been offered as to what the spot is and how it originated - a Multiverse is simply one of the possibilities. Much work needs to be done to and the outcome is anything but decided. So, this 'hard evidence' seems to be somewhat lacking. Also, think of how much of a hullaballoo there was over the Higgs boson, not long ago. That was considered big news. Other universes besides ours would be the BIGGEST story ever!

Thanks. . There is also the super-void hypothesis, and some have even suggested that the void is evidence of a parallel (or a sister) universe -meaning that both our universe and our sister-verse belong to a larger multiverse. Credit: Scientific American (Source) The last controversial idea – one than many physicists want to believe in – was cooked up by Laura Mersini-Houghton, who subsequently made five predictions about the nature of this cold spot in hopes of vindicating the existence of a multiverse. The idea proposed was essentially a “landscape multiverse” idea. This is something that is believed to be inherently tied to the multiple dimensions of string theory, which gives us an idea of the principles that must be met in order for life to develop in any given universe. In this scenario, our universe is but one in a massively huge number of universes – perhaps it’s just one in an INFINITE number of infinitely large universes–hurts your head, doesn’t it? (it does mine too) Out of the five predictions made in Mersini-Houghton’s paper, entitled “Cosmological Avatars of the Landscape I: Bracketing the SUSY Breaking Scale,” 4 have been verified, or at least they haven’t been ruled out. Here they are as follows: One of her predictions said that no evidence of supersymmetry (one of the hallmarks of string theory, which postulates the existence of a corresponding “super-particle” for all elementary particles with an integer-valued spin) would be found at the Large Hadron Collider. No evidence was acquired that gave supersymmetry leeway. (we did find the Higgs boson though – so that counts for something!) She was also one of the first scientists that believed dark flow (an eery observation that revealed that distant clusters are being “pulled at” from some great force outside of our local universe) was not tied to the great attractor, but something different. Some signs indicate that the force may be another universe tugging at our own. Instead of finding that the temperature variations inthe Cosmic Microwave Background radiation are random, a preferential pattern should be obvious. Upon inspection, we saw that instead of the patterns appearing completely at random, these “lumps,” which are slightly warmer or slightly cooler than the surrounding temperatures, are aligned with each other – along what has been dubbed the “axis of evil.” The so-called “preferred” direction of energy fluctuations (how the lumps were formed). This could essentially mean that we are off about certain aspects of the big bang model – if the big bang even happened at all. (OR, it could be that the shape of spacetime is much stranger than we previously anticipated. We’ll see.) (& 5) The team suggested that voids might have formed as a result of a sister universe pushing against us, repelling the gravity and matter of our own universe as a result. If one was found, a similar void should follow in the opposite hemisphere.. two things that rang true. The first of which, was the Eridanus supervoid, which we covered up top. The second one in the opposite hemisphere was found very recently. Could this mean we have finally seen some empirical evidence that we live in a multiverse? Maybe. Maybe not.

Sexton Blake Posted October 27, 2013 Share Posted October 27, 2013 If there can be one universe, there could be endless more. What is between them? Space. Endless space. Several years ago we detected something we call the Dark Flow. It is a BILLION light year hole in our universe. http://www.dailygalaxy.com/my_weblog/2013/10/is-our-universe-one-of-billions-new-planck-data-has-anomalies-caused-by-unknown-gravitational-pull-t.html Our universe is said to be expanding, but with this, things are heading into it. I say heading because they are not being pulled by some fantastic hidden mass. They are moving at constant speed, like as if a universe were contracting instead of expanding. Some say this is another universe inside ours or touching ours. Link to comment Share on other sites More sharing options...
