The Largest Structures in the Universe "two quintillion years"

[adamdyerseve]

i'm sorry, isn't the diameter of the universe: 93 million light-years?

then how the hell is "the vastest structure ever is a collection of superclusters a BILLION light-years away"?!!!!

there are only 93 million light-years!

@adamdyerseve yes the observable universe. But outside that is a whole different ball game. That is far beyond our leavel of measurement with todays tech. and of course the speed of light untill we get that data.

[wateronglass]

@yourboycal No, the observable univ. is about 13.6 Gly (13.6 billion light years). And then there's the unobservable part outside that caused by cosmic inflation and the limited time for light to reach us since the universe became transparent (surface of last scattering, cosmic background radiation being the first radiation observable today).

[yourboycal]

@wateronglass The observable universe is thus a sphere with a diameter of about 29 billion parsecs[15] (93 billion, or 9.3 × 1010, light years). wiki . Or is the cornoving distance?

[wateronglass]

@adamdyerseve Where did you get the figure 93 million ly from? The observable universe has an age of about 13.6 Gyr (13.6 billion light years = 13600 million light years).

[adamdyerseve]

@wateronglass although the universe is 13.8 billion years old, its diameter isn't respectively13.8 billion light-years (as first expected) but highly larger for many reasons that i do not have the knowledge to explain. only one of the reasons is that the universe has constantly expanded like a balloon due to the activity of the dark energy and dark matter which have functioned as anti-gravity elements, and thus the universe is estimated to be 93 billion light-years in diameter.

@adamdyerseve sorry man, but whoever told you the diameter of the universe was 93 million light years has seriously misinformed you. . Quasar 3C 321 is approximately 1.4 billion light years from Earth, Streams of particles that blast from the nucleus of 3C 321 are some 185,000 light years long.

This makes me feel big!

YOU JUST MADE ME FEEL small

I'd say we live on a pretty nice rock.

Molto bello!

[sex4xes]

but astonishingly our imagination is even bigger than that.Most likely we'll never know much about the physics of the extraterrestrial space,but our imagination always trys to fill the scientific gap,nevertheless how enormously big the object of venture finally is.In former times profane/religious beliefs manly formed the cognition of our environment,but even with the aid of modern science,we are pending on figments of our imagination to visualize(that is actually mostly not the genuine truth)=(

Pause the video at 3:34 please. Now sit back and watch... Does this image imply that we are in the middle of the universe?

[SmartGuy4today]

The Universe is not 3-Dimensional. Every single spot in the Universe is the middle. If you went across the edge of the universe, you'll end up on the other side. It is like how gravity has made the Earth roundish and as a result you can travel across and end up where you were. Except the Universe is hyper roundish. In retrospect, you'll end up where you are no matter what three dimensional form of travel you went by.

[Scorp316]

@SmartGuy4today In other words, no matter where you are, you're there.

[donte957]

@Scorp316 Being everywhere and nowhere is one of the same......

[Scorp316]

@donte957 It's a joke...

[ArchangelExile]

Should have zoomed into cities to further show how insignificant we are.

[NANOFORGE]

Thats amazing, once you travel 70 Light years from Sol you won't even beable to see it thus you would'nt even know it exists. We are so insignificant it is unreal.

[NANOFORGE]

Wow that thing is huge, and I mean huge. And people think the Earth is pretty big, well in relation to the universe our planet is'nt even worth mentioning.
