How electrons began to remain in orbits In the early hot universe, free electrons were being captured by protons, forming hydrogen atoms. The photons, emitted in this process called recombination, took away the difference between the summary mass of free … Continue reading
Increasing the visible size keeping the same amount of light emitted When we look at a distant source of light that spreads in all directions, we see only a portion of the photons emitted by it. As the distance from … Continue reading
How the decay of particles overtook that of antiparticles… It is observed that the number of baryons in the universe (protons and neutrons) exceeds the number of antibaryons at least ten thousand times. Such an asymmetry could arise in the … Continue reading
On changes in the rate of expansion of space In the first moments after the Big Bang, stretching the space of the universe occurred maximally rapidly, and the distance between the points grew from those microscopic to, possibly, exceeding the … Continue reading
On possible, but not soon change in the expansion of the universe The expansion rate of the space of the universe is governed by three major factors: the density of matter in it, the curvature of space of the universe … Continue reading
On the steady increase in all distances… After the Big Bang which occurred about fourteen billion years ago, space is expanding. It is possible to visually imagine the expansion looking as a figure drawn on the surface of a balloon … Continue reading
Changing the spectrum of light towards red as the distance from an observer There are astronomical observations showing that the rate of receding of galaxies from each other is approximately proportional to the distance between them. This law, named after … Continue reading
Variations in the rate of expansion depending on the predominant type of energy The equation written by Alexander Friedman on the basis of Einstein’s theory of gravity predicts the expansion of the universe dependent on density of the energy filling … Continue reading
On the stunning results of elementary particle physics and cosmology Modern knowledge of the microcosm and the cosmos is still far from perfect. For example, we can not describe in detail the strong interactions of elementary particles, or explain the … Continue reading
