The
universe!!!!!!!!! Can you imagine how big it is? Obviously we can't.
There are many scientists, astronauts out there even they can't imagine
how big our universe! They believe that we discovered just a tiny part
of our universe till now and also they guess that there may be
multi-universe out there. So, we live in one universe of them and
exactly where it is? There are billions of galaxy in our universe and
millions of solar system in a single galaxy. We live in one solar
system and our planet world is one of 8 planets of our solar system.
Can you imagine now how big our universe? In our galaxy there are
millions of solar system and scientists also don't find out exact
number. In our galaxy the biggest star discovered which is 2000 times
bigger than our own solar system star the sun. The sun is 1.3 millions
times bigger than our world. Do you have any idea how tiny place we have
for living compare to the vast universe? Oh my god, my head is
spinning. Below here a comparison of volume among planets, stars,
galaxy, universe are given. Each of them are acquired just a small part
compare to the next bigger one. World < The Sun / Solar System < Interstellar Neighborhood < Milk Way Galaxy < Local Galactic Group < Virgo Super-cluster < Local Super-cluster < Observable Universe
