Scientists have figured out why photons from other galaxies do not reach Earth

Scientists believe that some photons from stars in other galaxies are deflected by magnetic fields, and some by contact with intergalactic matter..

There are extragalactic objects in our universe, such as blazars., generating powerful streams of electromagnetic radiation. Only one part of the photons this stream reaches the Earth, and the other on the way is transformed into electrons, then back into light, and only then gets to us. The problem is that far fewer photons reach our planet than mathematical calculations predict..

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

The first assumes that after the photon is converted into an electron, it enters the magnetic field and deviates from the original trajectory, therefore, does not reach the Earth even after the second transformation into a particle of light.

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

Scientists from the Immanuel Kant Baltic Federal University say that it is not yet possible to test this in practice, but they are confident that someday humanity will be able to repeat the extreme space conditions within our planet..

Humanity is still at the initial stage of its development and is not owns the technology for the empirical study of deep space, but we are rapidly developing. For example, a breakthrough was recently made in rocket engine technology, which allows the flight to be extended from several hours to a month.
