Ten-dimensional space and supersymmetry. What does string theory explain?

We all die. But this is not accurateTen-dimensional space and supersymmetry. What does string theory explain?

Could our Universe be a “shadow” of multidimensional space and what does “sticky” membranes have to do with it? Why don't we see additional dimensions, and how are they “packed”? Why physicists look for symmetry between elementary particles, and why string theory requires twenty-six dimensions to work.
What if we imagine an elementary particle not as a ball (point), but as a string coiled into a ring that vibrates with a certain frequency? What answers (hypothetically) can such a view of the world give, explained Maria Savina, senior researcher at the JINR Laboratory of Theoretical Physics.
About 95% of the composition of the Universe is dark matter and dark energy, the nature of which cannot be explained by the best existing physical theory, the Standard Model. What questions does this theory not answer Maria talked about in the episode “The parameters are known, there is no explanation. Problems of physicists with the Standard Model.”
About where the energy for the Big Bang came from, what the Metaverse (Multiverse) could be, and could You can find out whether “everything” is born from “nothing” in the episode “Accidents are not accidental. How quantum theory explains the emergence of the universe.”

Why we haven’t been able to “catch” dark matter particles for almost a hundred years, and what role they could have played in the evolution of the universe, we talked about in the episode “Dark Matter: The Main Misconception or Great Discovery?”.

How can you explain that the density of dark energy is the same at any point in the universe, and whether it can be a cosmological constant, find out in the episode entitled “Out of one liter they made ten. How to solve the riddle of dark energy.”
What is wrong with the quantity black holes, and how gravitational waves will help study the Universe, listen in the episode “Interactions that distort space-time”.
We talked about why no one refuted Einstein’s main work, whether the great scientist was a bad mathematician, in the episode “Why Einstein was right? Theory of relativity and black holes.”
The episode was prepared jointly with the Joint Institute for Nuclear Research – an international intergovernmental scientific -research organization in the science city of Dubna (Telegram/VK/YouTube).
