It is known for long time that the Universe went through the hot Big Bang stage, with extraordinarily high temperatures of matter and extremely rapid expansion of space. It is less known that existing observational data strongly suggest that the hot Big Bang stage was not the first one, but was preceded by yet another epoch with completely different and unusual – properties. The best guess for that early epoch is cosmic inflation, but alternative theories are not yet ruled out. It is reassuring that future cosmological observations will most likely be capable of unveiling the nature of the earliest epoch  and physics that governed the Universe at that time.
