Some scientists claim they have found the size of Universe.

They say there are 10^11 stars in a Galaxy and their are 10^11 Galaxy
in universe. Taking average size of Galaxy they figure a sphere with
10^11 Galaxy.

But what is at the end of Universe. Lets consider Universe as a big
Ball. Then what is outside that Ball. Why we do not consider things
outside that ball to be part of Universe.

Does light stop going outside that Ball. If no then what is the Medium
wherethe light will be travelling outside the Ball.

If everything is vaccume outside the Universe then also that is a
space and we have to count that vaccum space as part of universe. But
how big is that Vaccume Is that Vaccume never ending or it again is
surrounded by a big Balloon.

And here again the same Question what is outside that Balloon. The
size is never ending it seems still Scientists have found the size of
Universe.

There is no vacuum outside because there is no outside.

Nobody claims to know the topology of the universe. And as far as "size"
goes, we're talking about the Hubble bubble. Which is all we can currently
"see" (as it were).

Far as what's "outside" everything, well, there isn't...

As I understand it, most scientists accept a finite and boundless
universe. I.E., there are no edges but there is a limited size. For this
to be possible of course, the universe must warp around itself in some
dimension that we don't have access to.

So, the part "outside the ball" isn't part of the universe because we
can't get to it.

The light can't escape the "ball".

Well i do not think that universe is either curved or infinite, i
think the guys behind the orginal Asteroids got the shape pretty much
right, except it is a 2D matrix transformed into a 3D matrix.

Whereever you decide to go your still in the matrix the Asteroid
matrix has boundaries that translate over the x, y field and of course
our universe has boundaries that translate over the x,y,z field.

It's like asking what's beyond the edge of the surface of the earth?
Nothing, there's no edge to the earth. Now, think 3D instead of 2D.
Except that we can cheat in the case of the earth and travel up/down
over it if we wish to, adding one more dimension to the surface, but
with the universe as 3D, we exhaust the spatial dimensions, so all you
see is all you get.

Hi Sanny, The radius of the known Universe is 45 Giga_Light_Years.
The Universe has no birth nor death,
just a soft limit to what can be observed.

Like ever-active yeast in a loaf of bread,
the cosmos expands everywhere, all the time.
It has no center of gravity, i.e. it's flat, Minkowskian.

When you tune-in the Cosmic Microwave Background radiation
on your radio ( it's in the static ) you're picking up photons
who's source is, at this precise moment in cosmological time,
45 Giga_Light_Years away.

See " The Cosmic Symphony ", Scientific American, February 2004,
at " "

I say " at this precise moment " because this souce is coming from
an ever-expanding sphere that has us, the observers, at its center;
so the actual source is never the same from one " moment " to another.

Also... 13.7 Giga_Years ago that sphere was ( notionally ) a point,
and was Planck dense, Planck hot, with unimaginably huge gravitational energy.
General Relativity tells us Gravity is the flip-side of Pressure/Density:
" 4D_Field = 8 * pi * G * T_αβ / c^4 ".

In 2-D, I visualise cosmological " time " as the Y axis and
( ever-flat, ever-static 4-D ) Minkowskian spacetime as the X axis.
But the Y axis is " Cosmic_Energy ", not time. " d Cosmic_Energy " is
a slice of cosmic spacetime in " cosmological time ".
Adding up the slices forms something like a " static 5-D hyperbola ".

w( z ) always equals -1, I posit, and Omega_Lambda is always .74,
i.e. Rho_Lambda ( and inflation ) was higher when Rho_Crit was higher
because a higher density dissipates ( i.e. " ticks " ) faster.

So, " Pressure_Cosmos = - ( .74 / .26 ) * Density_Matter * c^2 "

That last question is easy, we don't consider things outside the ball
to be part of the universe because there is nothing outside the ball.

Does light stop going outside that Ball. If no then what is the Medium
where the light will be travelling outside the Ball.

There are two possibilities:

1) The ball is a closed space. So the light continues in a straight
line and eventually winds up back where it started.

2) The ball is surrounded by a potential infinity of empty space which
is literally nothing (not even really space). In this case, the light
continues and the ball expands. (For example, you can only count to a
finite number, so what happens when you count past that number?
Answer, the finite number gets greater but is still finite.)

If everything is vaccume outside the Universe then also that is a
space and we have to count that vaccum space as part of universe. But
how big is that Vaccume Is that Vaccume never ending or it again is
surrounded by a big Balloon.

Space that is not between two things may literally be nothing. It is
also possible that the universe is closed.

And here again the same Question what is outside that Balloon.

Nothing.

The
size is never ending it seems still Scientists have found the size of
Universe.

Not if the universe is closed or empty space that is not between two
objects is literally nothing.

So, the part "outside the ball" isn't part of the universe because we
can't get to it.

More to the point, there is no "where" to get to and thus no "outside".
It's sort of like the orignal poster is asking, "what number is outside
the set of all numbers?"



Does light stop going outside that Ball. If no then what is the Medium
wherethe light will be travelling outside the Ball.

The light can't escape the "ball".

Given that (1) there is nowhere to escape and (2) light is a component of
the material universe, so we wouldn't expect that it could somehow exist
apart from it.

To make this a little more on topic, no god could exist "outside" the
universe either, since the universe is defined as "everything that ever
was, is or will be". Therefore god couldn't create the universe,
because, if he existed, he had to exist in the context of some universe.
Consequently, if god is eternal, so is the universe. However, since we
have evidence that the universe exists, it's easier and simpler to merely
postulate that the universe existed for all time without need for some ad
hoc "creator" to explain that which didn't need to be created.
