Is the universe infinite?

Here's an interesting video on the subject.

For all intents and purposes.

 

[Lasirius]

Who knows.

 

[wiegeabo]

I like the theory that the universe is finite, but with no boundary.

 

[RKO]

Infinite. Something that doesn't end.

How do we know something doesn't actually end until we reach it?

 

[Rocketman]

It has to end. **** this infinite stuff.

 

[Darthphere]

Who cares? We can't even get to Mars.

I think the universe is like a loop of string and the knot tying the ends together is a black hole. Go to the very ends of the universe and enter the black hole and it'll take you back to the opposite end (or at least your scattered atoms).

Do we exist in a universe that is infinite?

(infinite?) Macrocosm - Galaxies - Us - Atoms - Microcosm (infinite?)

Is there an infinite level of substructure to both the macrocosmic universe and the microcosmic universe?

We view the universe from our perspective and see that galaxies are large and atoms are small

Suppose we were able to view the universe from the perspective of the galaxy, how would it look?
Would we be able to see atoms if we looked down a microscope?
What would we see if we looked through a telescope?

Suppose we were able to view the universe from the perspective of the atom, how would it look?
Would we be able to see galaxies through a telescope?
What would we see if we looked through a microscope?

If we were to go on a journey deep into the microcosm, passing level after level of substructure, until we arrived say, 1000 levels below the atomic, what would the universe look like?

I know right?

Universe ain't gonna help me pay the rent. **** the universe.

Anyone wanting insight into this question needs to read Brian Green's The Hidden Reality, and read up on String Theory.

Math and physics points to an Inflationary Multiverse being the most likely possibility. Whether our universe is infinite, well, from an inside observer's perspective it would appear infinite. However, to an outside observers view it would appear finite.

As to your last question, scientists believe these extra deminsions are curled up in the microcosm in what is known as Calabi-Yau shapes. The energy required to delve this deep into the subatomic realm is lightyears beyond anything we are capable of harnassing on this planet.

Most people know so little about the universe its no wonder they pay it so little attention.

 

[Asteroid-Man]

Spacetime is "finite" - but if you go beyond that, technically, yes the Universe is "infinite". Time is ever surpassing as the tangible universe is ever expanding, but that said, that would require "emptiness" for spacetime to expand over, BUT we know that reality goes beyond just "spacetime" (as Einstein proved with his most famous equation). The answer is rather relative, as in a SPECIFIC moment, the Universe is finite, but it is ever expanding, and time is continuously passing (another form of expansion of spacetime), and then there's also different kinds of energy and unknown dimensions beyond that.

I know a lot about the universe and I don't pay much attention to it because I got bills to pay ya heard!

 

[8wid]

Time and gravity are finite. I think the real question is is dark matter infinite? The answer is maybe and the universe does not go on forever though because it is one of an infinite number of universes. Look up the theory of the multiverse to see what I mean, that could be infinite.

I hear ya. Without the universe I wouldn't have a profession to pay my bills.t:

I don't really understand the point you're trying to make.....not giving a rats fuzzy derriere about the universe doesn't = the universe not existing. The universe exists whether we understand it or not....which is why whether it's finite or infinite, or actually is the contents of a snow globe owned by a 7 year old autistic kid, or is actually a speck of dust on a night stand owned by Gil Gerard, doesn't matter, cuz come the 1st and the 15th, mofos got bills to pay.

My point was that the universe is my profession, or will be my profession eventually after god knows how many hours of schooling and ball busting work. My field of study is Astrophysics.
