There were produced gravitational waves during the cosmological inflation epoch in the evolution of the Universe. First step for obtaining the spectrum is to do the perturbation of action, which composes from Einstein-Hilbert action and the action for scalar field.
Gravitational waves from Inflation
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.

Have you ever considered about including a little bit more than just your articles? I mean, what you say is valuable and everything. But imagine if you added some great visuals or videos to give your posts more, “pop”! Your content is excellent but with images and videos, this website could certainly be one of the most beneficial in its field. Wonderful blog!
Thank You for a comment. I plan to do it later. Have a nice day.
