This work is based on modification of the general relativity, which includes effects of production /absorption of matter by the vacuum. The theory (without fitting parameters) is in good quantitative agreement with cosmological observations (SnIa, SDSS-BAO and reduction of acceleration of the expanding universe). In this theory we get rid of controversies (Big Bang, critical density of the universe, dark energy, inflation). It is shown that an effective age of the universe is about 327 billion years. Production of dark matter particles have started 43 billion years later. As an additional bonus in this theory, we got interface between dark and ordinary matter, which very likely exist not only in cosmos, but everywhere, including our body and our brain.
Key words: cosmology; age of the universe; dark matter; interface between dark and ordinary matter; subjectivity.
