I read somewhere some scientist predict Universe is donut shape. With
size of 156 Billion Lightyears.
We use light to see our universe.
So say a star is 1000 light year away then we can see it what it was
1000 years Back.
Age of Starts is arround 9 Billion years.
So when we see thing 100 Billion light years away. If a star was
present there then It is dead after 9 Billion years.
So Any Star we see outside 9 Billion years away are not present and do
not exist.
It may happen some star has born 5 Billion years back at a distance of
15 Billion light year away. So it will take another 10 Billion years
for light to reach us from that star.
So talking about any Galaxy/ Star which is away from 9 Billion years
is meaningless as there are high Chances that it do not exists now.
Since we cannot see Whole Universe at a single time we can never say
its correct shape.

If space has dimensions like, height, width, length and time, etc...
then wouldn't the appearance of space and the shape of space be
something inside of space only? I mean since there is nothing outside
of space and no dimensions the shape would not exist would it?

Above picture is a nice picture. If I think shape of the Universe I
would draw
a similar picture (where one space dimension is shrunken away from
full
3+1 dimensional space-time) except I would use instead a finite long
pseudosphere of radius about 13.8 Ga light years ?

Just *loved* that last paragraph...
Dr. Levin was doubtful, ''I suspect every last one of us
would be flabbergasted if the universe was so small,'' she
said in an e-mail message. When she first heard about
the new (WMAP) satellite data, she reported, ''I tried on
the idea that we were really and truly seeing the finite
extent of space and I was filled with dread.
''But I'm enjoying it too.''
