Until recently, everyone believed that the Universe was infinite (including the scientific class), in schools this idea was taught in geography, science, physics and other subjects alike. The advancement of technologies and the techniques of observation of outer space, added to much study, led modern physics to derive another conclusion about the questioning about from the extent of the Universe, henceforth to this process, physicists created a method to calculate the cubic volume and arrived at the number that is expressed as follows: the digit 3 and 72 zeros.
As the Universe is immense, there are dispersed celestial bodies of different sizes, ages and great distances between them. As for age, the oldest are the stars of large proportions, which reach up to 10 billion years, these reach such a large size that even the sun configures itself as a star of dwarf category, in this we can mention the star Antares, its size is 300 times larger than the solar star, the space in which it is situated comprises together the orbits of Mercury, Venus, Earth and Mars.
However, Antares is not the largest star, one of the stars of the double Y of the constellation Cocheiro, has a diameter that represents 3,000 times. the size of the Sun, based on the grandeur of this star, it would be possible to easily house the entire solar system in the space that it occupies.
Dwarf stars with a white hue, on the other hand, are composed of very dense matter and generate a weight very large, so some even weigh approximately 100 tons per centimeter cubic.
