What is the shape of the universe? Scientists are trying to understand

Despite the controversy between the conspiracy of the flat world, science has already found that the planet has almost a global shape and that the poles were a little flat because of the rotation force. But what is the form of the universe? Was it a triangle, a circle or completely flat?

According to experts, it is essential to understand the form of cosmos, because this is directly related to various phenomena observed in nature. For example, it is essential to understand the form of the universe, to examine the expansion, to determine whether it is finite or infinite, and to benefit from other features.

Although there are still aspects that we still don’t understand, the science structure is essentially dependent on two factors: the density and expansion rate.

In an area known as geometric topology, mathematicians and other experts examine the dimensions of shapes and areas, including the form of the universe.

As you walk in an open area, you probably have the feeling of being in a flat environment. However, this field can be considered as two -dimensional (2D), because any point in it can be defined by only two coordinates such as latitude and longitude.

Although the surface of the world is global in the global direction, it is also the surface of a 2D space (latitude and longitude) and a giant glasses (Toro), because all these areas allow two dimensions of action.

When scientists observe the universe, it can be seen that there is a three -dimensional (3D) area, just as the surface of the Earth appears to be two -dimensional (2D). It is on a publication on the website SpeechMathematics Teacher John Etnyre It explains that geometric topology can better understand the exact structure of the universe.

First, let’s understand what 2D and 3D gaps are:

• The surface of the world is considered a two-dimensional (2D) area, because we can move in two directions: north-south and east west.
• Since it allows movement in three independent directions in the three -dimensional area, the universe looks like three -dimensional (3D).

However, it is also possible to try 3D on earth; A practical example of this is the experience of flying on a plane. In addition to moving forward and sides, the aircraft can climb and go down.

What is the form of the universe?

Experts argue that the universe may have one of these three formats:

In the closed universe, it has a positive curvature similar to the surface of a sphere. Open, the surface has a negative curvature and forms a shape similar to a horse saddle. Already in the flat universe, there is no significant curvature; The area really looks straight, like a paper on a table.

Most experts argue that the most compatible format with the observations of the universe is the plane, because the measurements of the background radiation show that the curvature is extremely small, if any.

It is important to emphasize that there is still no definite result; Mathematicians and geometric heel experts continue to work to understand the real form of the universe.

“A flat universe corresponds to a universe with zero energy. We can measure the curvature with some uncertainties, so that the curvature is zero at a certain level of uncertainty. Although we can reduce this uncertainty, we can limit the most geometry, Prince Princeton University (USA) astrophysics professor and David Spergel astrophysicist, Live Science website.

Other dimensions of the universe

If the estimates are true, the universe may be flat, but with the properties of a three -dimensional curvature (3D), as we can move in three different directions. However, there is another important factor in understanding this format: time.

In addition to the three spatial dimensions, time is considered as the fourth dimension and forms the concept of space -time in the theory of relativity. However, some of the theories of physics, such as Sagittarius theory, make it think that there may be other dimensions beyond this four – this is still a hypothesis.

A flat universe can also help scientists who examine the standard cosmological model known as Lambda-CDM, which defines the expansion of the universe and the effect of dark matter and dark energy.

Although most of the scientific community agree with a straight universe theory, Other measurements of cosmos show that perhaps closed.

In any case, the debate continues and scientists are still looking for an answer based on a solid scientific evidence set.

We and the Evren

Investigation of the nodes, A main role in geometric topology is a role in geometric topology because they help to understand how it can be in the other. In this area, mathematical nodes represent different interconnected areas.

For example, imagine a wired wire with a knot. This wire represents an area of ​​one -dimensional (1D) in a three -dimensional environment. As if one was in the other.

“The theory of nodes in mathematics is to examine the closed curves in three dimensions and to examine the possible deformations that will exceed one another. The nodes can still be seen as forms created by intertwining and cheering a piece of rope, and then combining their ends. ”

Generally, Understanding mathematical nodes helps scientists examine the structure of 3D and 4D gaps. In addition, it has applications in various fields such as nodes theory, wire theory, physics, DNA rekomination and other fields of science.

Our universe seems to have three space dimensions, but can life exist in an area with only two? Do you want to know more? Understand why almost all objects in space are round. Until next time!
