89,942. The physicists found a second version of it. And then a third. Soon they had found five different string theories. That wasn’t single and it didn’t sound very definitive. String theory had begun to unravel. It seemed as if the dream of a theory of everything was as far away as ever. But just as the scientists were about to give up hope, a new and startling discovery would be made. This would inspire them to begin their quest again and force them at last to confront their least popular idea: parallel universes.

89,943. Super-Gravity though had been convinced there were exactly eleven dimensions. (M Theory & Parallel Universe & String Theory & Universe & Dimension & Gravity & Multiverse) ibid.
100,601. String Theory was in trouble. Its five different versions meant it couldn’t be the all-embracing theory Physics was looking for. Everything it seemed had been tried to save String Theory. Well, almost everything. In a final desperate move, the String Theorists tried adding one last thing to their cherished idea: they added the very thing they had spent a decade rubbishing – the 11th dimension. (M Theory & Parallel Universe & String Theory & Universe & Dimension & Gravity & Multiverse) ibid.
80,005. The tiny invisible strings of String Theory were supposed to be the fundamental building blocks of all the matter in the universe. But now with the addition of the eleventh dimension they changed: they stretched and they combined. The astonishing conclusion was that all the matter in the universe was connected to one vast structure: a membrane. In effect our entire universe is a membrane. (M Theory & Parallel Universe & String Theory & Universe & Dimension & Gravity & Multiverse) ibid.
80,006. When M Theory emerged, [Lisa] Randall and her colleagues wondered if it might provide the explanation – could gravity be leaking from our universe into the empty space of the eleventh dimension? Randall tried to calculate how gravity could leak from our membrane universe into empty space. But she couldn’t make it work. Then she heard the theory that there might be another membrane in the eleventh dimension. Now she had a really strange thought: what if gravity wasn’t leaking from our universe but to it? What if it came from that other universe? (M Theory & Parallel Universe & String Theory & Universe & Dimension & Gravity & Multiverse) ibid.
3,227. Dr [Laura] Mersini-Houghton’s idea was to manipulate the mechanics of that wave form with a branch of mathematics called String Theory. It seemed to provide an elegant solution as to why our universe emerged in the first place. (Big Bang & Universe & Science & String Theory) Horizon: What Happened Before the Big Bang? BBC 2010
86,172. String Theory ... Instead of the seventeen particles of the standard model, everything is made from a single object – an incredibly tiny loop of string. (Quantum Physics & String Theory & Dimension) Horizon: How Small is the Universe? BBC 2012
86,173. String Theory is underpinned by some fiendishly complex maths ... We live in eleven-dimension hyperspace. (Quantum Physics & String Theory & Dimension) ibid.
86,199. We don’t know what we are talking about. Many of us believed that string theory was a very dramatic break with our previous notions of quantum theory. But now we learn that string theory, well, is not that much of a break. The state of physics today is like it was when we were mystified by radioactivity. They were missing something absolutely fundamental. We are missing perhaps something as profound as they were back then.

115,193. String theory says that every single particle of matter and energy in the universe is actually a tiny vibrating string. A string that vibrates not in three dimensions but in nine. (Dimension & String Theory) Morgan Freeman’s Through the Wormhole s2e4: Are There More than Three Dimensions?
3,260. In our picture, there was a universe before the Big Bang, very much like our universe today: a low density of matter and some stuff called dark energy. If you postulate a universe like this, but the dark energy within is actually unstable, then the decay of this dark energy drives the two branes together. These two branes clash and then, having filled with radiation, separate and expand to form galaxies and stars.
Then the dark energy takes over again. It's the energy of attraction between the two branes: It pulls them back together. You have bang followed by bang followed by bang. You have no beginning of time. It’s always been there. (Big Bang & Matter & Dark Energy & Universe & String Theory & M Theory) Neil Turok
3,267. String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string. (Big Bang & Particle & String Theory) Edward Witten
3,443. Technically you need the extra dimensions. At first people didn’t like them too much, but they've got a big benefit, which is that the ability of string theory to describe all the elementary particles and their forces along with gravity depends on using the extra dimensions. (Gravity & String Theory & Particles & Dimension) Edward Witten
3,270. String theory has the potential to show that all of the wondrous happenings in the universe – from the frantic dance of subatomic quarks to the stately waltz of orbiting binary stars; from the primordial fireball of the big bang to the majestic swirl of heavenly galaxies – are reflections of one, grand physical principle, one master equation. (Big Bang & String Theory & Universe) Brian Greene
70,272. One of the strangest features of string theory is that it requires more than the three spatial dimensions that we see directly in the world around us. That sounds like science fiction, but it is an indisputable outcome of the mathematics of string theory. (Dimension & String Theory) Brian Greene
