量子力学、弦论:近期很难受吗?

               

听说了下面两个网页。可惜看不懂。

哪位物理学的有关老师给科普一下?感谢!

有什么比较明确的结论或观点吗?

Quantum theory breaks down when it comes to black holesNASA/CXC/M.Weiss

By Stuart Clark and Richard WebbGeneral relativity and quantum theory are the two pillars of modern physics, peerlessly accurate in their respective realms of the very large and the very small. But where they meet, they produce contradictory answers – and other problems they create mean they provide a far from complete picture.

For more on the basics of the theories, take a look at Reality guide: The essential laws of cosmology and Reality guide: The essential laws of quantum physics.

PROBLEM 1: Dark matter

Galaxies rotate too quickly for their visible matter

Earth whirls around the sun at a speed determined by its distance, the sun’s mass and gravity’s strength, which is a universal constant of nature. You don’t need general relativity to work that out: Newton’s old-school gravitation will do. The same law should apply to distant galaxies swirling around their common centre of mass.

In the 1930s, however, the astronomer Fritz Zwicky discovered that the outer parts of the Coma galactic cluster were rotating far faster than the cluster’s estimated mass allowed. In the 1970s, Vera Rubin confirmed the huge mismatch in a clutch of spiral galaxies ...

String theory has so far failed to live up to its promise as a way to unite gravity and quantum mechanics.

At the same time, it has blossomed into one of the most useful sets of tools in science.
