I mean who came up with this whole Giant Wall Idea?

I think you are referring to the so-called "Great Wall". Nobody said it's at the end of known space, though (whatever that is).
The "Great Wall" is a sheet of galaxies at least 500 million light-years long, 300 million light-years wide and 15 million light years thick (possibly more; the Milky Way cuts off part of it) situated some 2-300 million light years away from us, and is the second-largest known structure in the Universe.
It was discovered in 1989 by Margaret Geller and John Huchra based on redshift survey data from the CfA Redshift Survey. It was at the time the largest known structure in the Universe, but has since been displaced by the Sloan Great Wall, discovered in 2003 in data from the Sloan Digital Sky Survey, which is about a billion light-years away, and about 1.4 billion light-years in length.

Great question : )
Isn't that a legacy from the image of the original edition cover print of the alchemist on the cover of the 'Godel, Escher, Bach' book?
Maybe there are different editions nationally? We can't even count all the planets in the Solar system right now, or decide which are planets and which should be reclassified. I've always thought it was a cartoon of what is imaginable here & now, not an actual diagram. It really served to illustrate our sense of wonder at discovery, not depict a Wall. That's my two cents!

I didn't know that was a theory. If they would listen to the news once and a while, they would learn that space goes on and is unending. Giant telescopes view what no man can see. I think I would trust the scientists that run the telescopes to be telling me what is at the end of space.....

I don't know who said that. Anyway, space is so vast man shouldn't even worry about ever seeing the end of it. Man will become extinct before he ever finds it if it exists. We are only a speck of dust in this Universe and our time here is only a spark in time. Trying to find the end of the Universe is futile. I would rather spend my life doing something that has a possible goal in sight.

What's behind that Giant Wall I wonder...

people just cant conceptualize something with no end because everything that any human has ever known has an end. it may sound dumb to you, but when you tell someone the universe is infinite they dont reely know what the concept of infinity is because it is impossible to experience anywhere on earth.

i've never heard of Giant Wall Theory. are you sure you didn't make it up?

The universe is curved 4-dimensionally on itself (like the earth but one dimension higher). If you started out in a rocket ship on a straight path and could travel fast enough (faster than light), you would end up where you started (again, just like on the earth).

I didn't know that anyone had. Are You talking about the one out past Alpha Centura? The one they use to keep Us away from the civilised inhabitants of the universe?

I've never head this "theory" either. Maybe the guy from City Wok built it.
