Why does a singularity explode?

Why does the singularity explode? How long was it stable before exploding? Where does the singularity come from? Where does the energy contained in the singularity come from?

Since according to the law of conservation of energy, energy cannot be created or destroyed out of thin air, then where does the energy contained in singularities come from? Did it happen out of thin air?

According to quantum theory, the universe cannot remain at its smallest size forever, and it has a certain probability of spontaneous collapse. Although this probability is very, very small, since the time before inflation is infinite, no matter how small the probability is, it will definitely happen. In other words, if we live in an emergent universe, it cannot exist forever. If the beginning of the universe comes from quantum effects, then quantum theory must have existed before the beginning of the universe. So the question arises: Where did quantum theory come from? We don't know.

The universe may be like an eternally boiling ocean, with bubbles constantly appearing and expanding everywhere, and we are in a large bubble that was created 13.7 billion years ago. Space is expanding exponentially, and as time goes by, the volume of the vacuum will become extremely large. If there are more other cosmic bubbles out there, it's unlikely that this bubble of vacuum we call the universe formed early on. Therefore, the real beginning is likely to be as far away as the universe, too far away to leave any mark on our universe.

As a physical theory, the Big Bang has phenomena that can be explained and phenomena that cannot be explained.

The singularity is the beginning of time. There is no point in asking about the time before the beginning of the universe.

The purity of our universe Energy is close to zero. Add the mass, dark matter, and dark energy of all celestial bodies and subtract the potential energy between all celestial bodies (because the expansion of the universe requires overcoming gravity to do work, so the accumulated potential energy is negative), the result is infinitely close to zero. In other words, the net energy, or net mass, of the entire universe may be equivalent to that of a single elementary particle.

Answer in a scientific way: I don’t know, I don’t know, I don’t know, I still don’t know.

Answer in a religious (Christian) way: God did it, God did it, God did it, God did it.

"Before the explosion "There is no such statement. Before and after is the concept of time. In the explosion theory, there is time after the explosion.

Why does the singularity explode? Explosion theory cannot explain

Where do singularities come from? Where does the energy contained in the singularity come from? "Where" is the concept of space. There is space after the explosion

The universe that we can understand is approximately within a very small area. But for us, this is already the limit of the size of the universe that we can understand.

The singularity theory can only be established if it is assumed that this area is the entire universe.

The so-called singularity may just be a giant black hole with the same size as the universe we know.

As for the structure of the universe outside this area, and the connection between time, space, energy, and matter inside and outside the area, humans are not yet able to understand it.

And this connection may be the key factor in solving the mystery.

Maybe the universe outside our cognitive area has existed for countless billions of years. Maybe there has never been a big bang or a singularity. Maybe many newly generated matter particles are just the products of the death and explosion of black holes. And those matter particles that are tens of billions of years older than we think the age of the universe are just prodigal sons who have not been entertained by black holes for a long time.

God does not do boring things. The big bang and sending points may also be the same as heliocentrism. It is just a joke that we humans confidently play on ourselves in an era when technology is still very backward.

The laws of physics are derived from observation and derivation. The view of the Big Bang is also derived from actual observations. The observation result is that the universe is expanding, so the inference is that it was a point a long time ago. The expansion of the universe, also known as the Big Bang.

WHY

I don’t know if there is such a singularity and THE BIG BANG, but these are very interesting. Maybe these appear cyclically, the energy of the entire universe is conserved, and humans also have reincarnations. I think the universe should be an ultimate "0", which can be infinitely stretched forward and backward from countless dimensions. For example, the dimensions of negative infinity and positive infinity appear in pairs, but the total amount is always 0. But "who" pulled it apart? Alas, I don't know. Thinking about such a question can easily drive people crazy. The above is purely bragging, welcome to take advantage of it.

As long as you don’t abandon time, Without being able to escape the constraints of time, how can humans understand things "before the singularity"?

I personally believe that if the singularity ever existed, then this thing was the "genetic ceiling" set by the universe for human beings

I remember that the Big Bang is related to the phenomenon of quantum fluctuations. .

Quantum fluctuations are also like generating energy out of thin air, but they comply with the law of conservation. .

The matter and energy produced by the Big Bang should be equal to negative energy and negative matter. .

This can only be explained by those who engage in theoretical physics. .

This cannot be explained by physics, nor can it be understood by humans. . The Buddha does not answer how the world came into being, nor how it will eventually perish. If there was a big bang, the physical laws of the universe would have come about after that, and it could not have been speculated before.

< p>Whatever truly exists must be eternal.

These people actually believe that the entire universe was exploded from a single point

Then they lie to you and tell you that there are two possibilities,

One is explosion - Shrink-explode-shrink back and forth.

One way is to finish it after the explosion.

No matter how you compile it, the above big bang hypothesis can lead to the conclusion that the universe has a boundary.
