"Well, yes, they all exist. It's just a part of what we can see. "

"These things are all related to each other. Although we can't see them at present, we may not be able to see them in the future." The patient said.

"Yes, that's right, but there's a fatal problem with your statement." Mu Qiu said.

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

"In fact, you are still using an explanation, not only your one, but also others. The same thing can be done with parallel universe theory Mu Qiu said.

Parallel universe is also a multiverse, which is a theoretical set of infinite or finite possible universes, including all existing and possible things.

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

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

Since all matter in the universe is made up of quanta, these scientists speculate that since each quantum has a different state, the universe may also be made up of many similar universes rather than just one.

The concept of parallel universe benefits from the scientific discovery of modern quantum mechanics.

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

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

This theory of parallel universe was said by a patient to Mu Qiu before. At first, the girl said she didn't believe it, but later she had to choose to believe it.

After listening to Mu Qiu's words, the patient was surprised and asked, "do you say parallel universe? What is this thing? Why haven't I heard of it before? "

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

After that, the patient said, "maybe I understand what this means."

"But there's a big problem with this theory, and that's the most important one."

After hearing this, Mu Qiu asked curiously, "what's the problem? Can you explain that? "

"Well, I'll explain it briefly."

"Your theoretical explanation just now is only limited to a certain physical level, or it is just an explanation of a phenomenon and a hypothesis."

"But there will be some new problems in other aspects, so it can't be proved at all." The patient said.

The patient then looked at Mu Qiu, Mu Qiu very polite back to the patient with a smile, said: "you continue to speak, I'm all ears."

"All right!"

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

"For this question, we only define it by ourselves, and there is no absolute answer." The patient said positively.

Mu Qiu heard this patient say here, in the heart appeared different opinions and produce a little difference, said: "sorry, I interrupt."

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

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

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