One of the biggest unsolved problems of cosmology is to find a model for dark energy. People developed already many classical modifications of gravity, but it looks like that the correct explanation would be in the full quantum gravity. This is my presentation from a seminar in the department of mathematics at the Czech Technical University (Faculty of Nuclear Sciences and Physical Engineering).

I was studying theoretical physics at the Charles university in Prague. My interest is cosmology, quantum gravity and some areas of mathematical physics. Other my activity is playing the piano. I regularly give concerts. My favourite authors are S. Rachmaninoff, A. Scriabin, J. S. Bach, B. Martinů, J. Brahms and J. Cochran.
