How many of you actually know what a solar sytem, a galaxy and a universe is?

Question

I see so many people who have no idea! our solar system is in a spiral arm of the milkyway galaxy. There are some 200 billion other suns here. There are other galaxies, in fact, as Carl Sagan stated....there are as many galaxies in the universe as there are grains of sand on the Earth! You want to see more galaxies?

There is every kind of life you could imagine! In fact, there is every kind of lif you CAN'T imagine!

Answer 1

Thank you! Very informative (and correct) information!
Well, according to Physics, the same vast quantities, dimensions etc., we have to the large scale, we also have to the small scale, going from our size into smaller (cells, moles, atoms, electrons, nuclei, ....)
Further, according to my theory, the Universe we described above is the connection between other universes! As a matter of fact, each one of us is a Universe greater that the one we usually talk about! After all, people discover the dimensions, Greeks named 4 of them and we, somehow think we understand them! People understand only what has been named! That is why we can not comprehend the other dimensions, since we have not discover how the Greeks named them!
