Since then, when people still imagined the Earth as flat and standing on three whales, humanity has sought to understand the structure and dimensions of the world in which it lives. Modern scientific thought has gone immeasurably far from the notorious three whales. But even with the entire arsenal of telescopes and computers, scientists can only express more or less plausible and witty hypotheses about the size and structure of the universe.

Step 1
“An abyss has opened, full of stars; there are no numbers of stars, the bottom of the abyss,”wrote the genius Russian scientist Mikhail Vasilyevich Lomonosov in one of his poems. This is a poetic statement of the infinity of the universe.
Step 2
The age of the "existence" of the observable Universe is about 13, 7 billion Earth years. The light that comes from distant galaxies "from the edge of the world" has been traveling to Earth for more than 14 billion years. It turns out that the diametrical dimensions of the Universe can be calculated by multiplying approximately 13.7 by two, that is, 27.4 billion light years. The spherical model has a radial size of approximately 78 billion light years and a diameter of 156 billion light years. This is one of the latest versions of American scientists, the result of many years of astronomical observations and calculations.
Step 3
There are 170 billion galaxies like ours in the observable universe. Our galaxy is, as it were, in the center of a giant ball. From the most distant space objects, relic light is visible - fantastically ancient from the point of view of mankind. If you penetrate very deeply into the space-time system, you can see the youth of planet Earth.
Step 4
There is a finite age limit for luminous space objects observed from Earth. By calculating the age limit, knowing the time it took for light to travel the distance from them to the Earth's surface, and knowing the constant, the speed of light, according to the formula S = Vxt (path = speed multiplied by time) known from school (path = speed multiplied by time), scientists have determined the probable the size of the observable universe.
Step 5
Representing the universe as a three-dimensional ball is not the only way to model the universe. There are hypotheses suggesting that the universe has not three, but an infinite number of dimensions. There are versions that it, like a nesting doll, consists of an infinite set of nested and spaced spherical formations.
Step 6
There is an assumption that the infinity of the Universe is inexhaustible according to various criteria and different coordinate axes. People considered the smallest particle of matter to be a "corpuscle", then a "molecule", then an "atom", then "protons and electrons", then they started talking about elementary particles, which turned out to be not at all elementary, about quanta, neutrinos and quarks … And no one will give a guarantee that the next Universe is not located inside the next supermicro-particle of matter. And vice versa - that the visible Universe is not just a microparticle of the matter of the Super-Mega-Universe, the size of which is not even given to anyone to imagine and calculate, they are so large.
