It’s one thing just like the “Holy Grail” of physics: unifying particle physics and gravitation. The world of tiny particles is described extraordinarily properly by quantum idea, whereas the world of gravitation is captured by Einstein’s basic idea of relativity. However combining the 2 has not but labored – the 2 main theories of theoretical physics nonetheless don’t fairly match collectively.
There are lots of concepts for such a unification – with names like string idea, loop quantum gravity, canonical quantum gravity or asymptotically secure gravity. Every of them has its strengths and weaknesses. What has been lacking thus far, nevertheless, are observable predictions for measurable portions and experimental information that would reveal which of those theories truly describes nature finest. A brand new research from TU Wien might now have introduced us a small step nearer to this bold aim.
