Scientists have discovered why photons from other galaxies do not reach the Earth

Scientists have discovered why photons from other galaxies do not reach the Earth

Scientists believe that some photons from stars in other galaxies deviate under the influence of magnetic fields, and partly due to contact with intergalactic matter.

Extragalactic exist in our universeobjects, such as blazars, generating powerful flows of electromagnetic radiation. Only one part of the photons of this stream reaches the Earth, and the other along the way is converted into electrons, then again into light, and only then gets to us. The problem is that our planet reaches a much smaller number of photons than predict mathematical calculations.

An international team of scientists has improvedA computer program that helps simulate the behavior of radiation in intergalactic space. Scientists currently have two versions of dispersion.

The first assumes that after the photonis converted into an electron, it enters a magnetic field and deviates from the original trajectory, so it does not reach the Earth even after being converted back into a particle of light.

The second explains this by the fact that particles flying towards us interact with hydrogen, which is in the form of a plasma in intergalactic space.

Scientists from the Baltic Federal Universitynamed after Immanuel Kant they say that it is not yet possible to verify this in practice, but they are sure that someday humanity will be able to repeat the extreme cosmic conditions within our planet.

Humanity is still in its infancyof its development and does not own the technologies for the empirical study of deep space, but we are developing rapidly. For example, a breakthrough has recently been made in rocket engine technology, which allows you to extend the flight from several hours to a month.
