If the universe is finite in size, which it obviously should be, because its size is finite at the starting point of the clock (the big bang happened) 13.7 years ago, then at that point it should have some general size and so called , an obvious form only one would expect to see it from a reasonable distance. Anyway, what is the size and state of our universe and what confirms it?

To achieve this, the total size of the universe cannot be determined, because 1) it is expanding, and therefore its size is constantly expanding, but more clearly, 2) we can measure what we can actually observe. Since light has a finite speed, regardless of whether it is the fastest, there can be protests so long that their light has not yet had time to contact us, so we know nothing about them or about the existence of space. they live.. However, one can conclude that if the 13.7 million megadetonation happened a long time ago, and since the speed of light is the fastest known speed, then at that point the universe should probably have a range of 13.7 billion light years. .

However, just to confuse matters, we also cannot have a vague idea of â€‹â€‹the explicit size of our universe due to the Big Bang event and its consequences due to the fact that the rate of development of our universe keeps changing. Traditionally it was thought that the expansion rate of the universe should slow down under the same gravitational pull as the universe. If it finally stopped, and the opposite direction was not known: the jury was out. Then, in the last part of the 1990s, it was discovered that the expansion rate of the universe accelerates due to a secret repulsive force that cannot be absorbed much, called “mode energy”. Therefore, the current assumption is that the universe will continue to expand, growing continuously, at some point with increasing speed due to this repulsive force, “weak energy”.

We can in any case, in principle, measure the state of the universe. Anyway, the shape really depends on how much mass there is and how that mass plane shapes existence, or spacetime. This means that if you can trace the path of a light ray, the way it ultimately travels depends on the mass it passes through, so the path of the light characterizes the shape. It all comes down to math. Since the Big Bang is seen as a kind of explosion of matter and energy in this way, it certainly does not mean that the universe is round.

Assuming that the universe will eventually tend to become infinite in size (never catching but always trying to catch), that is one possibility. This situation can arise if the expanding universe is flat (where the points of the triangle are 180 degrees) or if it is sessile (where the points of the triangle are less than 180 degrees).

The testbed universe suggests that the light emission will spread anywhere from the parent and beyond, although experiments with various problems will result in short, small deviations. So if you emit two beam focuses aligned with each other, they will both travel very slowly.

The flat universe suggests that the emission of light, bending everywhere, to the right and to the left, back and forth, when it meets various giant objects (twist of light), in any case, eventually and measurably it moves generally in a general straight line. The two bulbs that radiate equally will remain the same in the long run.

Imagine a scenario where mass scattering has as its ultimate goal that the light fringe is eventually forced to bend back like a bug sliding around the outer shell of a sphere. So the universe is a closed universe. The universe is actually a round universe. Our lampposts will eventually circle the universe and repel us!
