Default How Big Is The Universe?



I say it is infinate, because:

1. the definition of universe "complex system of all things that exist", so
there is only one universe, that includes everything.

2. If the universe has some shape, any shape, what is beyond the
boundaries? (The rest of the universe)

3. If the universe is infinate, and matter is moving away, why is matter
still clumped in various galaxies? (Black holes feast on all matter near
them, until they finally begin to spit out the matter, and finally explode,
sending all the matter back out into the vicinity. Black holes keep matter
relatively placed throughout the universe)

4. If numbers are infinate, does it not stand to reason that something else
might be infinite?

5. All those that have measured and calculated the "limits" of the universe
have measured the limits of their technology to "see" into the universe, and
have calculated the limits of their knowledge.

That's enough for now, got to get back to work, infinity is a difficult
concept for most people to understand, since it can not be measured, except
in differential portions, but it is really quite simple, and even has its
own symbol. If this question won't get one to think, nothing will.

>I say it is infinate, because:

How would that definition imply that it was infinite? Perhaps all things
that exist does not take up an infinite space.


Nothing, I guess. How does that imply that the universe is infinite?


Matter could be clumped in galaxies regardless of whether the universe was
infinite of finite, as far as I can tell.


Actually, you are wrong, as no number is infinite. Can you give me an
example of any number that is not finite?


Perhaps. How does that indicate that the universe is infinite?

Perhaps if you had a clue, i might consider answering your queries, however,

Numbers are finite, if one is a moron, otherwise there is no limit, etc.,
etc.

Odin asked some important questions.

Unless and until you can answer them satisfactorily, your arguments cannot
stand.

Given an opportunity to address these questions, you chose an ad hominem
response.

You have just identified yourself as a common garden troll.

Plonk your brain, because users of this group should be sending messages to
the Kiddie Banter newsgroup. You clowns obviously are not capable of
intelligent thought, and one that argues with a fool is worse than a fool,
because they know better.

Guess how many fingers I am holding up? Now you are a psychic.

"All-inclusive" is not the same thing as "infinite."


The 2-dimensional surface of a sphere has a shape in 3 dimensions, but
it has no boundaries. The 3-dimensional volume of the universe has a
shape in 4 dimensions, but no boundaries. Your presumption of
'boundaries' to the universe is unjustified and empirically
unsupported. If you have trouble with the idea of 4-dimensional shapes
then you are not yet mathematically qualified to be participating in
this discussion.


Matter is not as 'clumped' as it used to be. The cosmic microwave
background radiation gives us a sort of 'picture' of the universe at
the moment when matter formed, and the universe was far more uniform
then. Still, there were local inhomogeneities that have since
'condensed' into galactic clusters and other structures we can now see.


....make that *most* of the matter near them. The infalling matter
interacts with otherinfalling matter, and can be ejected by something
like the 'slingshot' effect before it gets too close to the event
horizon of the black hole.


Not true. Anything that goes into a black hole stays there, like
alimony payments.


Gravity and inertia should get all the credit. Black holes are just a
part of that equation.


Congratulations, you have finally spelled 'infinite' correctly.
Unfortunately for your logic, it does not follow that any physical
object / phenomenon / quantity must behave exactly as any specific
mathematical abstraction does. Physics is all about finding somewhere
in the *infinite* universe of mathematical abstractions quantites,
operations, and relationships between them that behave in ways that
*MIMIC* what we observe in the real universe.


It is also possible to calculate *upper* limits to what *could be*
based on what we actually can see. For example, we can calculate an
upper limit to the mass of the black hole known as Sagittarius A in the
center of our Milky Way galaxy based on what we *do not* see the stars
near it doing.


There is far more to it that even *you* can imagine, as Georg Cantor
demonstrated:

Learning how to think like a mathematician, within propositional

I have never heard of black holes spitting out the matter or exploding. Can
you tell me where you got this information? Or did you just proudly pull it
out of your ass? Idiot.

I'll compare IQ's any day, and if you want to go further, I can be a double
for the late actor John Holmes. i suggest you brush up on physics, Balck
Holes send their matter out as they age, try NASA research center, they are
the "idiots" whose research I used.

And I used to think physics was what one took for an upset stomach, perhaps
I was right?

"The sign of a Intelligent man is not the realization of how much they know,
But rather the realization of how much they do not know."

But I know you think you already know it all, that much is painfully
obvious. You cant know it all, because I know some crack addict stands on
the street corner at a freeway off-ramp, and he assures me he knows
everything there is.

Hung like a gorilla, are you?


Perhaps you are taking about hawking radiation? That is the only way that
matter is thought to be possibly leaving a black hole. But that can hardly
be described as spitting out the matter or exploding. And Hawking radiation
has nothing to do with the black hole aging. Also, existence of Hawking
radiation still remains controversial today.


Ummm.. you lost me on that one...
