Surfing the Net I found five breathtaking pictures that I want to share just to make you witness the magnificence of our world ...... so fasten your seatbelts and get ready for an astonishing voyage!

EVERYTHING IN OUR UNIVERSE HAS A LIMIT

 

Everything in our universe has a limit. It may seem obvious, but it is something worth-considering. If everything has a limit, than there’s no such thing has “infinity”. Something without a limit cannot exist, because it is incompatible with our own reality. We know that there’s a limit to how cold something can get: that’s 0 Kelvin degrees, the minimum possible temperature. We know that there’s a limit to how fast something can go: that’s 300 000 000 meters per second, the speed of light. And we know that there’s a limit to how much of the Universe we can see and interact with.

THE LIMITS OF HUMANITY

The Large Magellanic Cloud  , a galaxy which belongs to the Local Group 

With our current technology sending a human to the closest star will take thousands of years. Even assuming that humanity will become a type 3 civilization ( an example of type 3 civilization is the galactic empire in the Star Wars series ) there will always exist a boundary beyond which  we could never go further: the Local Group. The Local Group is the group of galaxies to which our galaxy belongs; it includes about 70 galaxies , most of which are small in size, which is 0.00000000001% of the observable universe .

ARE WE ALONE?

Hi everyone! Today I want to start asking you a question: how big is the universe? “Huge” many of you will answer. And  that’s true! Our universe is enormous, maybe even infinite.  And from our small planet, we can only see a tiny portion of it. So, if it is so big, then it should be reasonably full of life, right? I mean, statistically speaking is very improbable that ours is the only planet in the entire universe in which life flourished. There must be others.
