Dear Ilya ,
Thank you for your questions.
1. Вы говорили, что темная материя может быть либо стабильной, либо нестабильной, с "темными" стабильными продуктами распада. Может ли темная материя быть динамически изменяющейся системой из нестабильных компонент, превращающихся друг в друга?
Yes, there may be an hierachy of decays of different unstable dark matter species. In the 2 semester we'll discuss such model. In the simplest variants they cannot convert in each other, since decays are irreversible processes, in which heavier species decay to lighter species, but not vice versa. However, in the models of interacting dark matter and dark energy, transitions from one form to another are also possible.
2. Если мы обнаружим из чего состоит темная материя (или ее часть), то будет ли обнаруженное по-прежнему называться темной материей?
There is no reason to change the name. This would be discovered dark matter, will remain dark (nonluminous) and nonbaryonic.
Regards

I think it's something wrong with video "The Universe" part 2. After 11th minute there's silence and no action.
It doesn't matter what you write, it matters who is your advisor!
