Is deep Space deep?

[Jet2]

If yes, how deep?

[sanctus]

How do you define deep?

[Tormod]

Is a high mountain high?

13.7 billion lightyears deep (within 1%) - measured in any direction from any contained point. Science 315 59 (2007).

The depth of space, while quantifiable, is virtually impossible for us to conceive, yet is still only a matter of perspective.

Me too.

May be Space shouldn't be measured or understood by Earth's standard?
But then how can we comprehen all the things around us?

Again, I don't know if the above questions make any sense...

I must harken back to 1972 with Hawkwind and their classic space rock album, Doremi Fasol Latido.

Space Is Deep.

Space is dark, it is so endless
when you're lost it's so relentless
It is so big, it is so small
why does man try to act so tall
Is this the reason deep in our minds

It does not feel, it does not die
space is neither truth nor lie
Into the void we have to travel
to find the clue that will unravel
Is this the reason deep in our minds

The secrets lie with our tomorrow
in each of us a hidden sorrow
The path goes onward through the night
beyond the realms of ancient light
Is this the reason deep in our minds.

I think they not only imply the physical depth of space but the profound answers we find there.

Isn't that the size only of the visible universe? It is the distance light can have travelled from the beginning of time no?

So space might be bigger (or deeper if you want), we can only talk about the part of the universe which can have (or actually has since we see the early light) causal contact with us...
