Ming Dynasty: Teaching The Prince Dragon-Slaying Skills At The Beginning

Future: As soon as these words of Yan Changqing came out, they caused huge waves among the people of future generations even 1,500 years later.

Later officials could not help but ask directly:

"May I ask Kesheng Banheng, what do you mean by the 'original me' and the 'me in the more distant future'?"

Future · Yan Changqing raised his head and looked through the stars in the universe at the people of future generations 1,500 years later, and said with a smile:

"The original me naturally refers to the me you see in the history books of later generations, that is, the original Kesheng Banheng who pushed Ming's scientific and technological civilization to the steam age and touched the electric and petroleum age!"

"And I in the more distant future will be the future Keban Hengshi created by you and other future generations!"

However, Yan Changqing's explanation in the future not only failed to relieve the doubts of future generations 1,500 years later, but instead made them even more confused.

What is the future that they and other descendants have jointly created?

What have they accomplished?

How come they don’t know!

Although fifteen hundred years apart, Future Yan Changqing seemed to see their doubts and explained gently:

"Since you can officially observe the past, then the younger generations starting from you can also observe the past. Is this understandable?"

Everyone in the later generations nodded, expressing their understanding.

After all, they are now able to observe the past, so people after them will definitely be able to observe the past, and there is nothing wrong with that.

"Then on the basis of being able to observe the past, the descendants after you will go a step further and be able to transmit future information to the past, which is the era when the original Kesheng Banheng clan lived. Is this understandable?"

Future·Yan Changqing continued.

Fifteen hundred years later, everyone in later generations nodded, expressing their understanding.

After all, now that they are able to observe the future, it is not impossible for future generations after them to further transmit information from the future to the past.

Maybe it’s bullshit!

Observing the future and transmitting future information17 to the past are not the same thing at all!

Not to mention how the younger generations after them passed information from the future to the past.

Even if the descendants after them can pass the information of the future to the past, the original scientific saint Ban Heng must have passed away long ago!

How did the original Ke Sheng Ban Heng accept the information from the future?

Or is it that the younger generations after them are really so powerful that they directly invented the time machine, and then took the time machine to travel from the future to the era when the original Kesheng Banheng clan was still alive?

Then all the knowledge of the future was transmitted to the original Kesheng Banhengshi, and finally the original Kesheng Banhengshi became the future Kesheng Banhengshi they see now?

Future Yan Changqing seemed to see through their thoughts, shook his head and said:

"Future technology has not yet developed to the extent of inventing a time machine that truly travels through time and space. At most, it can only interfere with the past in the future, but cannot directly go back to the past.

"Interfering with the past, or transmitting future information to the past, is actually not as difficult as you think."

"I wonder if you have understood the "Special Theory of Space-time Relativity" and "General Theory of Space-time Relativity" that I proposed?"

Fifteen hundred years later, later generations of scientists nodded repeatedly. How could a scientist not have studied the "Special Theory of Space-time Relativity" and "General Theory of Space-time Relativity" proposed by the scientific saint Ban Heng?

Even if you haven't studied it in detail, you must have understood it more or less, and even if it's not good, you have at least heard of it.

Then Future Yan Changqing did not care whether they had understood "The Theory of Space-Time Relativity" or not, and simply introduced:

"In "The Theory of Space-Time Relativity", I made these points."

"First, the relativity of time!"

"Time is relative, and its passing speed will change with the motion state of the object."

"Therefore, two characteristics have been extended. One is the time delay effect."

"The time-stretching effect means that when two objects move relative to each other, their time passes at different speeds.

"Specifically, when an object is moving close to the speed of light, time passes slower for it compared to an object at rest."

"The second is the bending of time."

"When an object is in a strong gravitational field, time will also be affected by curvature. This is because the gravity of the mass will bend the surrounding space-time, thus affecting the passage of time.

"Second, the relativity of space!"

"Space is also relative, and its length will change according to the motion state of the object."

"This also extends two characteristics. One is the space shrinkage effect."

"The space contraction effect means that when an object moves at a speed close to the speed of light, its length shrinks."

"This phenomenon is called length contraction, and length contraction causes objects to be observed to have different lengths in different reference frames."

“The second is, curved space-time.

"When an object is in a strong gravitational field, space is also affected by curvature."

"Third, the relativity of simultaneity!"

"The relativity of simultaneity means that two events that appear to occur at the same time in one frame of reference may not occur at the same time in another frame of reference."

"This phenomenon suggests that the sequence of events depends on the observer's state of motion."

"Fourth, the influence of gravity!"

"This also extends two characteristics. One is the influence of gravity on time."

"The gravitational field causes changes in the speed at which time passes. A stronger gravitational field causes time to pass slower, while a weaker gravitational field causes time to pass faster."

"The second is the impact of gravity on space."

"The gravitational field also causes the surrounding space to curve, thus affecting the trajectory of the object."

"And mass, energy equivalence, etc."

"Although "The Theory of Space-Time Relativity" is in the more distant future, it has also discovered its limitations and shortcomings."

"But in the era you live in, it is still applicable and correct for the time being."

Listening to the words of the Future Science Saint Ban Heng, most of the later generations of scientists 1,500 years later fell into a thoughtful state, and even vaguely thought about how to transmit information from the future to the past.

However, in the future generations of 1,500 years later, there will still be a small number of people who can become scientists, and there will also be a small number of people who can understand the words of the future Ke Sheng Ban Heng, so most of the humans in the Interstellar Chinese Empire still haven't understood it. .

Seeing this, Future Yan Changqing further explained:

"Through the relativity of time, the relativity of space, and the influence of gravity, we can know that the speed of time and the size of space are not relatively constant."

"Time and space are affected by the speed of movement of objects and the strong gravitational field at the same time."

"In a sense, the faster an object travels, the stronger the gravitational field it experiences."

"Then the time flow rate of the object within a certain spatial range will be slower than that of another reference object, and it can even reach a relatively stationary state!"

"Through the relativity of simultaneity, we can know that two things that seem to happen at the same time in the same frame of reference may not happen at the same time in the tenth frame of reference."

"Even two things that have happened one after another in the same frame of reference may also happen at the same time in another frame of reference!"

"For example, suppose the Earth moves at the speed of light and the Moon remains relatively stationary."

"Then if the earth itself is used as the frame of reference, there is a distinction between what happened inside the earth one minute ago and what happened one minute later89."

"But if the moon is used as the frame of reference, then what happened inside the earth one minute ago and what happened one minute later, from its observation point of view, are two things that seem to happen at the same time."

"For the same reason, conversely, even if thousands of years have passed inside the moon, it is relatively stationary in front of the earth moving at the speed of light. In fact, it is the same before and after a thousand years, and nothing has changed."

"What the earth, moving at the speed of light, sees is the moon from thousands of years ago."

"Using the moon itself as a frame of reference, people who have disappeared thousands of years ago have actually always existed in front of the earth moving at the speed of light.

"In addition to the movement speed of objects that can affect time and space, an overly powerful gravitational field can also do similar things."

"When the gravitational field is strong enough to a certain extent, it will distort time and space, causing the collapse of time and space, eventually causing the scale of time to disappear completely, and finally reaching a state of static space and stagnation of time and space."

"And inside this powerful gravitational field where space is still, time disappears, and space-time is stagnant, the phenomena that can be observed by observing anything outside are all when the powerful gravitational field becomes space still, time disappears, and space-time stops. The external scene at that moment!”

"Assuming that the powerful gravitational field achieved space stationarity, time disappearance, and space-time stagnation a thousand years ago, then for this powerful gravitational field, what it observes will always be the scene a thousand years ago!"

"The scene a thousand years ago has always existed compared to this powerful gravitational field and has not disappeared in the past."

"This is the so-called "Theory of Space-Time Relativity"!"

"As for the original Kesheng Benheng clan 1,500 years ago, compared to the earth and the humans on the earth, then it has indeed disappeared.'

"But for other objects that moved at the speed of light or even super-light speed 1,500 years ago, or for some cosmic objects with huge mass whose gravitational field is strong enough to make space stand still, time disappear, and space-time stagnates. In terms of "1

"The original Ke Sheng Ban Heng clan 1,500 years ago is still living well and has not passed away!"

Hearing this, the scientists of later generations, 1,500 years later, were all excited and uncontrollable. They had already understood the answer given by Future Science Saint Ban Heng, and even now they have thought of how to transform the future. The information is passed back to the past.

Maybe their specific operation process of transmitting future information back to the past is not necessarily the same as the operation process of future generations after them, but the theoretical principles of both parties must be the same.

To give 897 examples, the "Relativity Theory of Space and Time" written by Future Science Saint Ben Heng is equivalent to telling them that the answer is eight.

So under the premise that the answer is equal to eight, no matter whether they or the descendants after them multiply two times four to equal eight, or whether four plus four equals eight, it is just a different process, not the final answer that has been determined influential.

However, although the scientists of later generations understood it 1,500 years later, most of the humans in the Interstellar Chinese Empire still had a blank look on their faces that seemed to understand.

A thousand and five miles away

A hundred years later, the future Ke Sheng Ban Heng could not help but sigh.

At this moment, most of the humans in the Interstellar Chinese Empire 1,500 years later felt inexplicably guilty.

It's like a bad student listened to the top student's hard explanation for most of the day, but in the end the top student talked dryly, but he, the bad student, still didn't understand.

After the future Kesheng Ban Heng sighed, he gave another example:

"To give a very loose and unscientific example, suppose that at the speed of light, time is a one-way straight line, and then coincides with a two-dimensional plane space.

"

"Then in this two-dimensional plane space, the moving speed does not reach the speed of light, or it is an object that reaches super-light speed [or its own strong gravitational field does not reach enough to cause

An object that makes space stand still, time disappear, and space-time stagnate. "

"They are objects in this two-dimensional plane space that are constantly shuttled by the timeline.'

"You can only see each time point under the timeline, and the past of each time point cannot be traced back!"

"Time is a long line for objects in this two-dimensional plane space."

"However, if the moving speed reaches the speed of light, or if it is an object that exceeds the speed of light, or if its own gravitational field is strong enough to cause space to stop, time to disappear, and space and time to stop.

stagnant objects. "

"Then the object will break through the constraints of the two-dimensional plane space [and become a condescending existence in the main three-dimensional space."

"At this time, when the object looks at the time in the original two-dimensional plane space, it will be found that there are traces of the original time points.

"Then the traces left by these time points will become timelines, and finally these timelines will turn into a time plane that is similar to a two-dimensional plane!

"

"After the timeline becomes a time plane, the object has the ability to trace past time points and past timelines in the two-dimensional space from the three-dimensional space."

"So it also has the ability to transmit information from the future to the past."
