    Imaginary large numbers in determining the size of the Milky Way

    Weird and exciting numbers related to the Milky Way galaxy, which were produced by researchers and astronomers, and were mentioned in a report published on the "Life Science" website, which specializes in scientific news.
    Researchers said that the mass of the Milky Way is about 890 billion times the mass of the sun in our solar system, according to the report that the New York Post extracted some parts of.
    This number equates to 1.8 tradeshilion kilograms, or the number 1 followed by 42 zeros.
    According to the report, the mass of the galaxy is also equal to about 6 billion billion billion elephants.
    Compared to planet Earth, the mass of the Milky Way is equal to 296 quadrillion the mass of the Earth, knowing that a quadrillion equals a million billion, or 1 and to the right of it 15 zeros.
    The Milky Way is also 135 times the mass of the supermassive black hole.
    Researchers tend to "weigh" galaxies by studying the movement of stars within galaxies, and to show how gravity affects those stars.
    The disk of our galaxy, for example, is rotating in an irregular spiral, according to the study's co-author and Imperial College London astrophysicist, Fabio Ioco.
    "The bodies at varying distances from the center of the galaxy revolve around the center at different speeds," Ioco said in a statement to "Life Science".
    The researchers compared their findings with previous work in this field and found that they are compatible, according to the study, which was published Monday in the ArkSev database.
    "If you do this based on the varying distances from the center to the very far ends, then you will get an estimate of the mass, and thus it is possible to calculate not only the total mass, but also the mass distribution," said Ioku.
