Is a football a sphere?
Most modern Association footballs are stitched from 32 panels of waterproofed leather or plastic: 12 regular pentagons and 20 regular hexagons. The 32-panel configuration is the spherical polyhedron corresponding to the truncated icosahedron; it is spherical because the faces bulge from the pressure of the air inside.
Is a football a 3D shape?
3D shapes are not flat shapes, they are solid shapes like a football or an ice cube.
Is a football a 2D shape?
it is made of lots of leather pieces- 12 black pentagons and 20 white hexagons, all of which are regular. (Yakimento, 2015) On this football the 2D shapes are tessellated together as to leave no gaps between the shapes. The pentagons an the hexagons must have the same length of sides for this to happen.
Can we travel to other dimensions?
We have a universe with three dimensions and if you include space-time, four. So in Stranger Things, characters don’t travel to another dimension but rather another version of Earth in a parallel universe. Hypothetically, this holds true.

The different universes within the multiverse are called “parallel universes”, “other universes”, “alternate universes”, or “many worlds”.
How does universe look like?
The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (46.5 billion light-years or 4.40×1026 m) in any direction. The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×1026 m).
