Dark energy and the anthropic principle

Popis výsledku v původním jazyce

The Hubble constant is split into two terms H = H1 + H2 , where H1 is a decreasing function due to the Big Bang and the subsequent gravitational interaction that slows the expansion of the Universe and H2 is an increasing function that corresponds to dark energy which accelerates this expansion. For T = 13.7 Gyr we prove that H2(T) > 5 m/(yr AU). This is a quite large number and thus the impact of dark energy, which is spread almost everywhere uniformly, should be observable not only on large scales, but also in our Solar system. In particular, we show that Earth, Mars and other planets were closer to the Sun 4.5 Gyr ago. The recession speed 5.3 m/yr of the Earth from the Sun seems to be just right for an almost constant influx of solar energy from theorigin of life on Earth up to the present over which time the Sun?s luminosity has increased approximately linearly. This presents further support for the Anthropic Principle.
