Is the universe the smallest hole that man can fit his head into?

In Comparision with the Spritual Creation, the Vedic scriptures does discribe this Material Universe to be as good as a Stool Pit. \nWe have indeed put our head in this Pit, and we still think that this is a place of enjoyment, and this miserable existance is a way of life.

Yes.  Infinity goes in both directions.  Space is space, large or small.  IMHO  ;-)

Yes. There are absolute, eternal laws that exist in the universe. You break them at your own peril.

I asked that question to Dr. Brian Greene, author of "The Elegant Universe".  His answer was "the Universe is continually expanding", and therefore, you can't put a size on it.  The Universe, in a sense, CREATES the space it's expanding into.  It is all-encompassing.

You've probably seen the pictures of a grid with a giant funnel extending infinitely downward.  That's not the shape of the hole itself, but a map of the curvature of space near the singularity.  The singularity, or "hole" itself is a point of infinitely large density and infinitely small size.

the universe is finite yet has no boundaries. it may be something like the two dimensional surface of a sphere.  nothing inside or outside the sphere exists for the two dimensional surface.  nothing exists outside the universe in this model.

I ponder that a lot sometimes, when I get completely overwhelmed by the pace of my life and the obsessive narcissism of people.\nI have this little 'shoe-box' theory: We are really at a loss to begin explaining exactly HOW BIG the universe actually is, so we may as well just be this compact galaxy, stuck at the back of somebodys wardrobe in another space and time.\nYes, I'm a weirdo...

A black hole is a spacial anomalie with an extremely high gravitational mass, and supercondenses matter into an infinitismally small singular. If all the matter in the universe could be condensed into a ball the size of a speck of dust, then the size of the ball inside a black hole would be a fraction of a fraction of that, too small to see with the most powerful microscope on planet Earth. The hole however is much different, similar to a funnel. So at different points in the hole the size measurement is different. There is no actual hole however, more like a bend in the fabric of space, so nothing ever actually leave the universe, only changes density, form and location, among other things.

The Universe itself doesn't necessarily need something to hold it together, it just is.  \n\nAs far as what's outside the Universe, science cannot answer that question, so it is left to speculation.\n\nMy opinion: the Universe exists within the realm of God, so the spiritual world is outside of it, but that is just an opinion, not fact!

the universe WAS a singularity (everything packed into an tiny tiny tiny space) before the big bang. So, i guess, technically, you  can go see the consequence of a singularity by opening your eyes. but see one as a singularity, i have no idea, sorry.

'Outside the universe' seem to me to belong to the universe!\nYou think the universe is that small???\nI do not know the answer on your question.\nLet me ask you: can the space time be curved without mass or only thanks to mass?

No...man loses his wisdom even thinking about it.  As soon as his little head starts to think - this can be many times in a day - all the energy is drained from his big head and is redirected into his little head. This is the point he  loses reason.  It's interesting to note, the recovery process is almost immediate after he leaves the specific area, drained. That's when he remembers he's married...or whatever

The smallest anything can be is called Plank length and it is approximately 1.6 × 10 (to the -35th power) meters.  \nAssuming "we" is the earth, we are very small compared to the size of the universe.  The "volume" of the observable universe is about  1.9 × 10 (to the 33rd power) light years, and the earth has a volume of approximately 8.2 x 10 (to the 12th power) miles, or 4 x 10 (to the -26 power) of a light year.  The universe, then, is about 4.7 x 10 (to the 58th power) times bigger than the earth.

the universe is one big fractal and that is most likely true, but don't think to much about it or your head might explode. Our solar system is a tiny tiny aberration on the pinhead of space. There are parralels everywhere... in nature and in fractals. Think of it as so much bigger than your senses could ever understand and you'll be fine... just don't go killing busloads of people.

Currently man believes or percieves only 3 spacial dimensions.  Height, length and depth.  String Theory, the unification theory of quantum and relative gravity hypothesizes up to 11 other spacial dimensions.  God resides where man can not comprehend and angels fear to tread.  Remember, the heart has its reasons of which reason knows nothing.

The space-time continuum is the universe in four dimensions. And considering that I'm alive, then yes, we can survive in it.

Life would remain simpler with no strings attached.  However, string theory deals with a universe with more that the dimensions we know day-to-day.  For example, you can calculate the diagonal of a square or a cube and the result has physical significance you can deal with.  The forth demension is time but what is meant by the diagonal of that figure no longer a plane or a solid?  What do we know of even greater dimensions, especially if they describe the very small that we can never see?  Certain of the equations that have been produced have enoumous numbers of solutions and it is difficult to find the correct solution and how to test it.  And that is only scratching the surface of a subject that has attracted some of the best brainpower on the globe.  Good luck.
