"Hmm, yes, all of this actually exists. In fact, that's just a part of what we can see."

"These things are interacting and interrelated. Although we can't see them at the moment, we may not be able to see them in the future." The patient said.

"Yes, that's right, but your statement is a bit fatal." Mu Qiu said.

"What's the problem?" the patient asked.

"In fact, you are still using one kind of explanation, not just yours, there are others. The same thing can be done with the parallel universe theory," Mu Qiu said.

A parallel universe is also a multiverse, a theoretically infinite or finite collection of possible universes, including all existing and possible things.

All space, time, matter, energy and the physical laws and physical constants that describe them.The universes contained in the multiverse are called parallel universes.

A long time ago, when some physicists were observing quantum, they found that the quantum state of each observation was different.

Since all matter in the universe is composed of quanta, these scientists speculate that since each quantum has a different state, it is also possible that the universe is not just one, but is composed of multiple similar universes.

The proposal of the concept of parallel universe benefited from the scientific discoveries of modern quantum mechanics.

Some scholars used this analogy when describing parallel universes. They may be in the same space system but different time systems, just like two trains running on the same railway line.

They may be in the same time system, but the space system is different, just like cars driving in the upper and lower passages of an overpass at the same time.

This cosmic parallel theory was told by a previous patient to Mu Qiu. At first the girl said that she did not believe it, but then she had to choose to believe it.

After hearing Mu Qiu's words, the patient asked in surprise: "You mean parallel universe? What is this thing? Why haven't I heard of it before?"

It took Mu Qiu almost an hour to briefly explain to this patient the most basic point of the parallel theory.

After speaking, the patient said: "Maybe I probably understand what this means."

"But this theory also has a big problem, and this is the most important."

After hearing this, Mu Qiu asked curiously: "What is the problem? Can you explain it?"

"Well, then I will explain briefly."

"The theoretical explanation you just gave is actually limited to a certain physical level, or it is just a certain phenomenon, but a hypothetical explanation."

"But if there will be some new problems in other areas, it is impossible to prove it at all," the patient said.

The patient looked at Mu Qiu immediately after speaking. Mu Qiu politely returned the patient with a smile and said, "You continue to speak, I will listen to her."

"Ok!"

"The parallel theory you mentioned is actually a question of time and space."

"For this question, in fact, it is just our own definition, and there is no absolute answer." The patient said affirmatively.

When Mu Qiu heard this patient say this, different opinions appeared in her heart and a little disagreement, and said, "Excuse me, let me interrupt."

"In fact, you just said that my parallel theory is not absolute, but our own definition is wrong. I thought so at first."

"But then I discovered that this concept has actually been put forward in many places." Mu Qiu said.

As soon as Mu Qiu finished speaking, the patient was stunned.
