My lecture at the Indian summer school in Prague in 2017 about gravitational waves

One of the predictions of General Relativity are the gravitational waves. It was announced in February 2016 that the gravitational waves were finally observed for the first time in the history. It means that we obtain completely new window for the observation of the Universe. Before that event we observed the Universe almost only in electromagnetic radiation. But we have only theoretical models, what happened in the first second of the evolution of the Universe, because we are not able to detect any radiation from this epoch of evolution. But if we are able to detect primordial gravitational waves, this situation will change. Gravitational waves were already observed at LIGO and VIRGO terrestrial observatories. People prepare so called LISA observatory in space, it will be prepared for launch around 2029. And the next generation of observatories are BBO, which will be already able to detect primordial gravitational waves. I try to explain in this lecture, how we describe gravitational waves in modified gravities.

I was studying theoretical physics at the Charles university. I am interested in cosmological perturbation theory and mathematical methods of quantum gravity. I am also working in neuroscience. You could find my articles, for example, in online journal European Physical Journal C or mathematical journal Topology and its applications. I participated - during my Ph.D. - in many conferences, for example, in Odessa, Odessa International Astronomical Gamow Conference-School 2013, and cosmological conference Modern cosmology, CMB and LSS in Benasque 2014, or Winter School of Geometry and Physics in Srní 2015. Other my activity is playing the piano. I regularly give concerts. My favourite authors are S.Rachmaninoff, A.Scriabin and F.Chopin. You could find more informations at

  1. With havin so much content and articles do you ever run into any issues of plagorism or copyright violation? My site has a lot of exclusive content I’ve either created myself or outsourced but it looks like a lot of it is popping it up all over the web without my authorization. Do you know any solutions to help stop content from being ripped off? I’d definitely appreciate it.

    1. Hi Carleen. There are usually my presentations from seminars, which I have here in Czech republic or elsewhere. So I don’t have problem that someone will download it or spread it.
