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.

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.
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.
I’ve been absent for a while, but now I remember why I used to love this website. Thank you, I will try and check back more often. How frequently you update your web site?
Hi! I usually put a new content once in month, after I have a seminar.
