How Vast Of The Universe
It is not possible for the human brain to acquire an overview of how the vast size of the universe, we not only don't know how great our brain size, but were not able to imagine how vast the universe is.
if we start from the earth where we are based, and then spread to the outside, then we will understand why it is the case, the Earth is just one of a very small part.
the solar system consists of the Sun, the planets that revolve around the Sun, the asteroid was composed from the start correspond, which is the small planets and a meteor.
throughout our solar system is only a small part of the from series bigger solar system again, called " the Milky ways'. the of the milky way was made up of millions of starts, most of these have far greater than our Sun, and they formed a solar system of its own, too.
so the stars we see in the series of our Milky ways, which we call milk lines, all of which shaped the Sun, they are on such a distance away from our Earth, so we measure distance with the "light years" and not according to the size of the miles.

that light can traverse a distance of 6 trillion miles in a year, the brightest star, that is located closest to the Earth is Alpha Centauri, do you know how far? he is 25 trillion miles from Earth.
lets us confine these talks with the environment of our milky way galaxy, it is estimated to contain 100,000 light years, we mean 100,000 x 6 trillion miles! being the milky way we did recently is a fraction of the solar system.
maybe there are still millions of milky way, behind of milky ways, and probably all of the milky way, when compiled, will is also part of a series of larger solar system again, it is therefore impossible for us to obtain the shadow of the vast size of the universe.
incidentally, according to estimates of experts of science, the universe was in the stage of developing expanded, this means that, after passing through a number of billion years two groups of the milky way will form a distance twice as big, between one another, compared with the distance they owned previously.
