Scientists figured out three general possibilities:
1.) CLOSED - The Universe can be like a sphere, thus having a positive curvature. (imagine a ball) Therefore it will be finite in size, but it would have no boundaries. If you would go long enough in one direction you would end up in the same place. In such a Universe, a large enough triangle would have more than 180 degrees and parallell lines would eventually meet. A closed Universe would end up in a 'Big Crunch', meaning that eventually it would stop expanding and due to its own gravity it would shrink back. We live in such a Universe, if its density is greater than a so called critical density.
2.) FLAT - The Universe is like a sheet of rubber that can be pulled in every direction forever, thus its space is infinite and would have no boundaries. Triangles add up to 180 degrees and parallel lines remain parallel, just like on a sheet of paper. However, don't get confused in here. I used the analogy of a sheet of paper or rubber, to explain that the geomatrical characteristincs would be the same as of a 2D model. The Universe is obviously not literally flat (we're not some shapeless cartoon characters, right?). Such a Universe is possible, if its density equals the critical density.
3.) OPEN - The Universe is saddle-shaped, thus having a negative curvature. Therefore its space would be infinite and it would have no boundaries. It would keep expanding forever at an accelerated rate. Large enough triangles would have less than 180 degrees and paralell lines would move apart if long enough. If the Universe's density is smaller than the critical density, then we are part of such Universe.

Explain the shape of the universe please?
There really is no shape of the universe. It is like air, it really has no shape. But maybe many, many light years away it reaches to the end of the universe and it has shape. But right now our technology cannot tell, or go that far.
What shape do you think the universe is?
Since all of the planets, and moons, and stars seem to have a spherical shape, it is possible that the universe may be a sphere.
Is the universe has a definite shape and definite volume?
No
Where is earth in relation to size of universe?
The universe's shape is unknown, therefore we cannot tell where the earth is. but compared the the universe the earth is a tiny tiny speck
What controls the size and shape of the universe?
big bang explosion
Why will the big dipper change in shape?
the universe is always changing
What is the most common 3D shape in the universe?
The atomic sphere.
The fate of the universe depends on 2 things what are they?
1.the shape of the universe 2.the rate of acceleration or de-acceleration
Are all 100000000000 galaxies in our universe be any size and shape?
Yes, galaxies can be any size and shape.
What are the three current theories on the shape of the universe?
Sphere, Hyperbola and Flat.
What is the shape of the space?
space, or the universe, has no defined shape it is constantly expanding, as everything gets farther and farther apart When it comes to the universe the size and shape are undefinable, unless you get into really hardcore theoretical physics that make sense only to Stephen hawking
What was the role in gravity on shaping your universe?
maintains planets in their orbits; makes stellar bodies round
