We don't know how big is universe but know how big is our planet. We learn all the things from this planet, and about limitation, sky is the limit, born, grown up, funeral all these are part of society that's why we say human is the social being, we can't make anything can change the shape only, practice makes a man perfect, it depends on ones choice what he wants to be, we can't force them, what we can do we can suggest them as you do. Have a nice time.
