When I see sky I only see small stars twinkling at night.

Now When I see sky with a large telescope I will again see many stars.

How do I know whether a twinkling Object is a Star from our Galxy or
it is some other Galaxy.

How do scientist see the very far away Galaxies and see Billions of
Stars in it.

Can they really see each star in the Galaxy and how do they count that
there are 100 Billion stars in that galaxy.

It may happen That is just a Star with a Billions of small planet
sized things.

And when we are living inside the Galaxy how do astronomers descide
that our galaxy is spiral.

As far as I know whichever direction I see I can see infinite number
of stars.

So what are they basis of these assumption?

What I bilieve is stars are randomly distributed throughout the
Universe.

And Universe is Finite or Infinite is again a Question.

Say Universe is Finite then it must have some Shape.

Lets assume it has a Shape of a Sphere.

Then That sphere must have some radius.

What happens about the place outside that sphere.

Say our Universe Radius is "r"

What are the things ar a distance 2r, 3r, 100r, 1000r. Why do we not
consider the things at a distance 1000r as part of our Universe?

Why we confine our Universe to be a Sphere of radius r ????

So far, so good.

Still OK.

I knew it was too good to last.

Get an education. Learn some optics.

In general, stars in other galaxies are not resolveable as individual
stars.

Learn some optics.

Telescopes.

Can they really see each star in the Galaxy and how do they count that
there are 100 Billion stars in that galaxy.

No.

Get an education. Learn some optics. Learn some math.

It may happen That is just a Star with a Billions of small planet
sized things.

Not a chance.

You mean "our galaxy"?

Simple observation.

As far as I know whichever direction I see I can see infinite number
of stars.

That's because you are uneducated.

So what are they basis of these assumption?

You mean your assumptions?

Ignorance.

What I bilieve is stars are randomly distributed throughout the
Universe.

The universe doesn't care what you believe.

And Universe is Finite or Infinite is again a Question.

Not to anyone with an education.

Say Universe is Finite then it must have some Shape.

Lets assume it has a Shape of a Sphere.

Then That sphere must have some radius.

Just about right.

What happens about the place outside that sphere.

There is no outside the universe.

Say our Universe Radius is "r"

With a bit of reading you would know that r is currently estimated
to be about 46 billion light years.

Obviously typing "size of the universe" into a Google search is beyond
your capability.

What are the things ar a distance 2r, 3r, 100r, 1000r. Why do we not
consider the things at a distance 1000r as part of our Universe?

There are no "things" beyond r.

Why we confine our Universe to be a Sphere of radius r ????

There is nothing beyond r.

Get an education.

I regret to inform you that the fascist imperialist Google has
prevented me from replying to you in the style and manner I wished
to. Fraternal greetings, Mars is the People's Planet.

There is no outside the universe.

There are no "things" beyond r.

So you know the Radius of Universe it is 46 billion light years.

We cannot see things beyond r = 46 billion light years

Since we cannot see things beyond r We assume there is nothing outside
it.

So according to you 2r, 3r, 100r, 1000r do not Exist just because we
cannot see that distance.

It is just like saying a Blind person says Since I cannot see anyone
in this world there exist no Human Beings on earth. Is it not absurd.

I think Light travels using photons. and Photons decay after 46
Billion years So light from sources 46 Billion Years away cannot reach
us.

Just like Every particle on earth has a lifetime after which it
decays.

Everything including proton, nutron, electron decay after a long time.
Sameway I think photon decays after 46 Billion years So any thing
which is 46 Billion Light years away we cannot see them.

May be I am correct who knows? What do you think?


So according to you 2r, 3r, 100r, 1000r do not Exist just because we
cannot see that distance. May be the photons comming from those
Sources do not reach us as they get decayed.

1) You look up the sky coordinates in a catalogue or use software.
2) You look at the (resolved) image. Stars don't have structure or
extent.

Stars in it.

Bifocals.

Can they really see each star in the Galaxy and how do they count that
there are 100 Billion stars in that galaxy.
[snip rest of crap]

103,475,223,482 stars. Oops, supernova! 103,475,223,481 stars.

I think you are a babbling, ignorant, idiot.

If you bothered to read the links I provided you would know everything
you posted is blindingly ignorant.

The universe is expanding hypersphere surface. It is 4 dimensional
sphere. There is no boundary of edge to the universe. This is Albert
Einstein's closed universe; finite yet unbounded. 3 dimensionally
there is no center either.
