A Quote by Michio Kaku
The next big accelerator might be the ILC in Japan, a linear collider which might be able to probe the boundaries of string theory. So we physicists have to learn how to engage the public so that taxpayers money is used to explore the nature of the universe.

The beauty of string theory is the metaphor kind of really comes very close to the reality. The strings of string theory are vibrating the particles, vibrating the forces of nature into existence, those vibrations are sort of like musical notes. So string theory, if it's correct, would be playing out the score of the universe.
We need a theory that goes before the Big Bang, and that's String Theory. String Theory says that perhaps two universes collided to create our universe, or maybe our universe is butted from another universe leaving an umbilical cord. Well, that umbilical cord is called a wormhole.
For a theory to be scientific it must be capable of being refuted by the evidence. Given that we have had three decades of rising temperature followed by a decade of stable and slightly falling temperatures worldwide, how many decades would you require before you are convinced that the theory on which you are committing £400bn of taxpayers' money might be slightly wrong?
It might seem paradoxical that the biggest scientific instruments of all are needed in order to probe the very smallest things in nature. The micro-world is inherently 'fuzzy' - the sharper the detail we wish to study, the higher the energy that is required and the bigger the accelerator that is needed.
I sometimes think about the tower at Pisa as the first particle accelerator, a (nearly) vertical linear accelerator that Galileo used in his studies.
When we understand string theory, we will know how the universe began. It won't have much effect on how we live, but it is important to understand where we come from and what we can expect to find as we explore.
Superstring theories provide a framework in which the force of gravity may be united with the other three forces in nature: the weak, electromagnetic and strong forces. Recent progress has shown that the most promising superstring theories follow from a single theory. For the last generation, physicists have studied five string theories and one close cousin. Recently it has become clear that these five or six theories are different limiting cases of one theory which, though still scarcely understood, is the candidate for superunification of the forces of nature.
With billions of years, who knows what science might make possible? Why, it might even make it possible for an intelligence, or data patterns representing it, to survive a big crunch and exist again in the next cycle of creation. Such an entity might even have science sufficient to allow it to influence the parameters for the next cycle, creating a designer universe into which that entity itself will be reborn already armed with billions of years worth of knowledge and wisdom.
The best theory comes from string theory, which states that dark matter is nothing but a higher vibration of the string. We are, in some sense, the lowest octave of a vibrating string.
So when you ask me how string theory might be tested, I can tell you what's likely to happen at accelerators or some parts of the theory that are likely to be tested.
Some string theorists prefer to believe that string theory is too arcane to be understood by human beings, rather than consider the possibility that it might just be wrong.
In acting, you get to explore such an artistic side with different characters to research and learn and explore different things inside yourself and I do that anyway, so I might as well be doing something that I already do, as in a second nature to me, on film.
Turn around, and the people you thought you knew might change. Your little boy might now live half a world away. Your beautiful daughter might be sneaking out at night. Your ex-husband might by dying by degrees. This is the reason that dancers learn, early on, how to spot while doing pirouettes: we all want to be able to find the place where we started.
Is the universe 'elegant,' as Brian Greene tells us? Not as far as I can tell, not the usual laws of particle physics, anyway. I think I might find the universal principles of String Theory most elegant - if I only knew what they were.
I hope we find evidence of dark matter in the lab and in outer space. This would go a long way to proving the correctness of string theory, which is what I do for a living. That is my day job. So string theory is a potentially experimentally verifiable theory.
String theories, for instance, they require seven additional dimensions. So, as experimentalists we should, with our high-tech instruments like the Large Hadron Collider, just listen to nature and to what nature wants to tell us.
