## Dark Energy from Quantum Gravity

Here are my slides from the presentation about dark energy at the Czech Technical University in Prague.

## Dark energy

Here is my presentation from the Tux Workshop 2022. I talked about dark energy. People tried to solve this problem in classical physics, but I explained the possible solutions in quantum gravity.

## Adventures of modern cosmology

Cosmology is a science about the origin and evolution of the whole Universe. These are my slides from the seminar in Banská Bystrica in Slovakia, 17.1.2022.

## Seminar 14.12. 2021

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).
