I have heard that the M Theory is capable of solving every problem related to the origin of the universe...is it true? If so, how is it possible?

M Theory doesn't (yet) exist. It is a speculation about what a Theory of Everything might look like, by Ed Witten. As a speculation, it's now a decade old and it hasn't materialized yet. Like many non-existent theories, it is immensely powerful and has enormous explanatory power

Almost nothing is known about the dynamics about most of the very large number of M theory vacua that do not fall into one of the classes described above. As emphasized even dynamics about stringy vacua is completely understood only in the trivial case of zero string coupling. Indeed our ignorance about M theory is great. Until recently there have been no candidates for a complete (note 6) description of the dynamics of fluctuations about even one nontrivial M theory vacuum.
However, work inspired by a conjecture made by Maldacena in 1997 seems to have established that dynamics about certain families of M theory vacua is identical to that of certain well understood quantum field theories called gauge theories

Let me put one thing staright to you.. M- theory is NOT about the origin of the universe. It says that like our universe, there are other parallel universes which co -exist. These universes they say are again contained in an infinite dimension which is again contained in an infinite dimension and so on...
The m- theory is all about understanding the behaviour of our universe through the eyes of an imaginary observer standing on the infinite dimension. Scientists are first trying to guess what the shape of our universe is... ios it in motion.. if yes then in which direction,, with what velocity... does it have any chance of colliding with another universe.. etc etc...

No, it's not true.
Science can tell us much about what happened since a split second after the universe was formed. It tells us nothing about it's origin, nor is it likely to in our lifetime.
As a famous physicist once said:
"The big bang theory says nothing about what banged, how it banged, why it banged, or even if it banged at all."

No, it can't. It still has plenty of problems, and loads of it can't be tested experimentally, yet if ever.
