Why is the Big Bang cone shaped?

The apex of the cone represents the beginning of the universe. Its flat circular base represents its current radius. The height represents its age, while the slope of the cone represents the age and radius or its space time.

Why is the universe not a sphere?

The shape of the universe deals with the shape of space. A spherical balloon can expand as it is inflated, just as a flat rubber sheet can be stretched and remain flat. So our expanding universe could be flat, open, or closed. If the density parameter is 1, then the universe is flat.

Why is the universe not uniform?

The answer is that in the first 10−23 or so of a second after the Big Bang the universe went through a process of exponential expansion called inflation. This was driven by a field called the inflaton field, and during inflation quantum fluctuations in the inflaton field got magnified up to cosmological scales.

Is the universe shaped like a cone?

The roughly cone-shaped structure is our 4-D universe. The lines along its length and around its circumference show how the galaxies evolve and where they are located. The shape (in cross-section) is a parabola. Where everything starts in 4-D is the Big Bang.

What kind of curvature geometry of space does the universe have if the universe had a density that is equal to the critical density?

flat
If the density of the universe exactly equals the critical density, then the geometry of the universe is flat like a sheet of paper, and infinite in extent.

Is the universe flat or not?

Most cosmological evidence points to the universe’s density as being just right — the equivalent of around six protons per 1.3 cubic yards — and that it expands in every direction without curving positively or negatively. In other words, the universe is flat.

What is uniform universe?

The results indicate that the universe formed uniformly in all directions, as predicted by current cosmological theories. The 1995 image was taken in a small patch near the Big Dipper constellation, which astronomers previously thought was completely blank.

Why the universe is not expanding?

In addition to slowing the overall expansion, gravity causes local clumping of matter into stars and galaxies. Once objects are formed and bound by gravity, they “drop out” of the expansion and do not subsequently expand under the influence of the cosmological metric, there being no force compelling them to do so.

What do you see is the fate of the universe will the universe continue to expand or will it eventually contract because of gravity?

If the gravity within the universe is strong enough, it could reign in the expansion and cause the universe to contract. If not, the universe will continue to expand forever. Based on the matter we can see, such as galaxies, stars and planets, the density of the universe seems to be below the critical value.
