The origin of singularity digital currency

Singularity is the existence in the universe predicted by general relativity when explaining the origin of the universe; Original & quot; Point. This hypothesis holds that the universe was proced by the big bang of singularity. Before the big bang, there was nothing in the universe, no space-time and matter, only a singularity with infinitesimal volume, infinitesimal curvature, infinitely high density and heat. There was neither time nor space before the big bang. Once singularity is involved, it means that space-time itself cannot be defined and all scientific laws are invalid

however, if any information from the previous universe can not affect the next universe, it is meaningless whether the previous universe really exists. To ask where the singularity of the big bang came from before is a matter of metaphysics. It is no longer a matter of science, because there is no such thing as before

1. mathematically:

   a singularity is usually a point that is called undefined on a mathematical object, or when it cannot complete the order under special circumstances, so that it appears in the set of exceptions. Such as derivatives. For example: in the equation

   real number, when a point appears & quot; Approach & quot; To ± The undefined point is a singular point x = 0. The equation g (x) = | x | (see absolute value) also contains the singular point x = 0 (since it is not differentiable at this point). Similarly, there is a singular point (0,0) at y = x, because this point contains a vertical tangent. An algebraic set has a singular point (0,0) in the (x, y) dimension system defined as y = 1 / x, because it does not allow tangent to exist here

2. physical singularity:

   singularity refers to the point where space-time begins to bend infinitely

   scientists believe that a singularity exists in the center of the black hole, which may be the starting point of how the universe began from the big bang. For example, inside a black hole, the mass of all stars compresses in a narrow space, and may even become a single point

   contemporary physics theory holds that this point is infinitely dense, although scientists believe that it is the proct of the collapse of physics e to the inconsistency between general relativity and quantum mechanics. In fact, scientists suspect that singularities are very dense, but not infinitely dense

   Space time -- a point of time with infinite curvature. Space - time, where it begins and ends. Einstein said that time and space are the illusion of people's understanding. Time is because of the change of everything in the universe, so that people have the concept of time. At the singularity, with the birth of the universe, there began to change, which is the beginning of the universe. The classical theory of general relativity predicts that there is a singularity, but because the existing theories fail there, that is to say, we can not use quantitative analysis to describe what is at the singularity

   if there is one or more time like or light like incomplete geodesic lines in a non extendable space-time, then the space-time is called a singular space-time, and the point that the incomplete geodesic lines tend to is the singular point of space-time

Before the birth of the universe,

in the quantum ocean of nothingness, nothingness is full of singularity waiting for the explosion

the energy burst out of these singularities has positive and negative effects, and will soon annihilate, but there is one exception

e to various uncertain factors, a certain particle did not annihilate, so huge energy burst, which is now called the big bang of the universe

the universe was born from this singularity, which contains all the energy and mass of the universe from the beginning. The universe was born from energy, procing time, space and matter

everything we see now is the result of this singularity

will the universe eventually become a big black hole, return to extinction, and then erupt from the singularity of the black hole

there are several versions of the end result of the universe, one of which is similar to this idea

according to the theory of great collapse, however, when the universe expands to a critical point, gravity will eventually defeat the dark energy, and the universe will begin to shrink, and it will shrink faster and faster, and finally form a collapse potential, shrink into its Schwarzschild radius, and become a big black hole with only one singularity left in the center

Yes, it's really hard to understand the big bang theory. We have such a huge universe, it is from the expansion and explosion of a point the size of an atom. So even if we can agree with this theory. Where does this point come from

singularity is generally regarded as a point, but in principle they can take the form of one-dimensional line or even two-dimensional membrane. According to the equation of general relativity, as long as a Schwarzschild black hole without rotation is formed, The matter inside the event horizon of the black hole must collapse into a point of infinite density under the action of gravity, namely a singularity (see Penrose, Roger). The uniform expansion of the universe from the Big Bang is the mirror reversal of the collapse of the black hole, which means that the universe was born in a singularity
