This represents approximately 4,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 of which SIX-Ft. the number of photons emitted by the stars since the time of the universe as a result of the Big Bang of about 13.7 billion years ago – it's actually the amount of light from the stars in the space.
"Our measurement allows us to reach the first billion years of the universe, and this is a very interesting time in the universe that is so far away from us that it does not attach any powerful telescopes. The objects there are so distant and so weak that we do not, we can see, but we are seeing light from these objects, "the scientists explain.
According to them, from the Big Bang, about one trillion galaxies containing hundreds of trillions of stars have formed. The calculation of the light volume of these cosmic bodies is an effective tool for understanding the structure of the primitive universe.
Based on data from the gamma-telescope of NASA Fermi Gamma-ray, researchers analyzed the light of 739 blazars (strong sources of gamma rays) in the visible universe to determine the rate of death. absorption of extragalactic background light or accumulated background radiation.
The astronomers then removed the light emitted by other sources, for example, black hole compression discs, zodiacal light and the weak radiation of the Milky Way, p. The result has been multiplied by the volume of the universe.
As a result, they received a number equal to 4.10 to 84 degrees, that is, 4,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 1,000,000,000,000,000,000,000.
Passing through space, gamma rays can be absorbed by interacting with photons of stellar light. And the more stellar photons there are, the more light absorbs. Based on this theory, we can calculate the number of absorptions we see to understand the density of starlight.
