along depends describe elementary forces particles people string theory using
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.
describe directions particles string therefore turns vibrate ways
Having those extra dimensions and therefore many ways the string can vibrate in many different directions turns out to be the key to being able to describe all the particles that we see.
physics strings theory
String theory is 21 st century physics that fell accidentally into the 20th century.
thinking littles strings
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.
might strings theory
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.
important strings theory
One very important aspect of string theory is definitely testable. That was the prediction of supersymmetry, which emerged from string theory in the early '70s.
concept precisely theory
On the other hand, we don't understand the theory too completely, and because of this fuzziness of spacetime, the very concept of spacetime and spacetime dimensions isn't precisely defined.
regardless supposed
Regardless of any deviations, it was clear I was supposed to end up in math and physics.
It's an exaggeration to say that I came up with M-theory.
trying
If you are a researcher, you are trying to figure out what the question is as well as what the answer is.
discovered particles physicists trying vibrate
You have that one basic string, but it can vibrate in many ways. But we're trying to get a lot of particles because experimental physicists have discovered a lot of particles.
badminton movies tend
I don't care about movies. I tend to play badminton once a week.
long might gravity
There was a long history of speculation that in quantum gravity, unlike Einstein's classical theory, it might be possible for the topology of spacetime to change.
giving shapes different
One of the basic things about a string is that it can vibrate in many different shapes or forms, which gives music its beauty.
