To be fair the human brain is simply not developed enough to be able to fully understand just how massive and complicated the universe is, however during this process we do get amazed and sometimes can’t believe what we are learning – Just watching the video will leave you scratching your heads.

How Massive Is The Universe?

With the advancement in technology, astronomers are now able to look back in time to the moment’s right after The Big Bang. This could actually mean that the entire universe may lie within our view. But the size of the universe depends on a number of things, including its shape and expansion. So how big is the universe? The simple truth is, it’s so large that no scientist can even give a number.

What About The Observable Universe?

Back in 2013, European Space Agency’s Planck space mission released the most accurate and detailed map ever of the universe’s oldest known light. From this map we learned that our universe is 13.8 billion years old. Planck calculated the age by studying the cosmic microwave background.

“The cosmic microwave background light is a traveller from far away and long ago,” Charles Lawrence, the U.S. project scientist for the mission at NASA’s Jet Propulsion Laboratory in Pasadena, California, said in a statement. “When it arrives, it tells us about the whole history of our universe.”

Because of the connection between distance and the speed of light, this means scientists can look at a specific region of space that lies 13.8 billion light-years away. To give an example: Just like a ship in an empty ocean, astronomers can position their telescopes to peer 13.8 billion light-years in all directions, which puts Earth inside of an observable sphere with a radius of 13.8 billion light-years. The word “observable” is key; the sphere limits what scientists can see but not what is there.

While we are not able to know what is beyond the observable universe we can compare some of the discovered planets and stars.

Now and again I come across a video that blows my mind and this is the latest one. Hope you enjoy it as much as I did. Much Love.
