Chapter 523 Speed ​​changes the illusion of time

As for why this civilization did not take direct action, Liu Xiu guessed that perhaps it was the same reason why humans would mess with ants and other insects when they were bored!
But no matter what, no matter what the purpose of that alien civilization is, developing ourselves is the real truth. We can't just give up just because the enemy is too strong!

Liu Xiu agreed very much with what Li Yunlong said at the beginning, that is, even if he died, he had to bite a piece of flesh from the enemy, even if it was an ant, he could bite the enemy all over.

Not to mention the mysterious civilization that has always been weighing on Liu Xiu's mind, the space stone created by the prehistoric civilization that Liu Xiu brought back not only allowed the scientists of the wandering blue planet to re-understand space.

It makes the theory of relativity no longer perfect and applicable to the laws of the universe. More importantly, it breaks Einstein's conclusion that gravity distorts space and speed can change the speed of time.

The new definition of time is time. The new definition of time theory is that the flow rate of time will not change due to any object.

In the same universe, the flow rate of time is the same everywhere. The fact that time slows down as the speed increases is actually an illusion of material deception.

Speed ​​affects the passage of time, which stems from the time dilation effect mentioned in the theory of relativity. The faster an object moves, the slower the time passes for the object.

A theoretical example is the "twin paradox". The younger brother of twins leaves the blue planet in a sub-light speed spacecraft. When he comes back, the younger brother on the spacecraft is no different from when he left, while the older brother who stayed on the blue planet is already an octogenarian.

Another real-life example is a navigation satellite. The satellite orbits the blue planet at a speed of more than 7.9 kilometers per second, so the passage of time on the satellite is slower than on the surface of the blue planet. If the time is not calibrated in real time, the navigation position displayed will be far off, so the clock on the navigation satellite is calibrated at regular intervals.

So since the speed of movement affects the passage of time, how big is this impact?

This effect can be calculated using the time dilation effect formula of the theory of relativity. The effect of speed on the speed of time passing is not linear, but increases in geometric series.

For humans, 50% of the speed of light is already fast enough, a speed that is difficult for humans to reach, but the time dilation effect caused by this speed is only 1.15 times.

That is to say, if we fly a spaceship at 50 percent of the speed of light to leave the Blue Planet, without considering complex issues such as takeoff acceleration and return deceleration, if we fly one minute away from the Blue Planet, only 1.15 minutes will have passed on the Blue Planet, or 1 minute and 9 seconds.

However, if the speed is increased to 90% of the speed of light, the time dilation effect will be more obvious, about 2.29 times.

That is to say, if you fly a spaceship at 90 percent of the speed of light to leave the Blue Planet, one minute later, about 2.29 minutes will have passed on the Blue Planet.

So in the example of the twin paradox, if the brother on the blue planet is flying at 90% of the speed of light, he will not become an old man, but just a middle-aged man.

However, if the speed reaches 99 percent of the speed of light, the time dilation effect will reach 7.09 times, which means that if the spacecraft leaves the blue planet for one minute, 7.09 minutes will have passed on the blue planet.

If the speed is further increased to 99.99 percent of the speed of light, the time dilation effect will reach more than seventy times.

That is to say, if you leave Blue Planet for one minute in a spaceship traveling at 99.99% the speed of light, seventy minutes will have passed on Blue Planet, or one hour and ten minutes. At this point, the time dilation effect is already very obvious, and the situation described in the twin paradox can be realized. So, what if you fly at the speed of light? If you fly at the speed of light, the time dilation effect will reach infinity. In fact, for an object moving at the speed of light, time and space do not exist at all. No matter where you want to go, you can get there instantly.

Because in the theory of relativity, the time dilation effect and the length contraction effect are equivalent. When the time dilation effect tends to infinity, the length contraction effect also tends to infinity, so time is infinitely long and distance is infinitely short.

That is to say, for an object moving at the speed of light, even if it travels through the entire universe, it only takes a moment to complete. However, this is only theoretical and cannot be achieved in reality. Because we live in four-dimensional space-time, which is a world composed of three-dimensional space and one-dimensional time, for objects moving at the speed of light, there is no concept of space-time, so it is not a product of four-dimensional space-time. Based on this, we can also say that light is wandering on the boundary between four-dimensional space-time and high-dimensional space-time.

Because from the theoretical perspective of relativity, no matter how close to the speed of light, it is achievable, but to jump from infinitely close to the speed of light to the speed of light is an impossible task.

Because once an object with rest mass reaches the speed of light, its mass will tend to infinity, so infinite energy is required to achieve this. However, there is no infinite energy in the universe, so it is naturally impossible to propel it to the speed of light.

However, this result of various experiments proving the theory of relativity was only after several rounds of technological explosions on the Wandering Blue Planet, and it was finally successfully proved that the conclusion that the speed of light can change the speed of the passage of time is completely wrong.

The most important point is that superluminal speed has been achieved. Whether it is the superluminal speed of the curvature engine or the superluminal speed of space jump, it has been proved that the speed exceeds the speed of light and will not produce any theory of going back to the past.

But these are not important. After all, they all use opportunistic methods and are not true superluminal speed.

Antimatter spacecraft can easily reach a speed of 70% of the speed of light.

The spacecraft in this situation will indeed cause the time on the spacecraft to slow down. For example, after a long journey, this spacecraft found that the clock on its spacecraft was much slower than the normal clock.

It is basically the same as the situation on the positioning satellite, but is the actual result really like this? The closer to the speed of light, the slower the flow of time will be, and eventually you can achieve immortality.

However, the reality is that the measurement of time causes the deviation of time speeding up.

The current method of measurement is atomic clock measurement, which measures time by the frequency of transition electromagnetic waves. The time can be accurate to within one second in tens of millions of years.

In ancient times, people used water drops to measure the amount of time that had passed, but this method of measurement was not very accurate.

Because the falling of water droplets is sometimes affected by the size of the droplets themselves, the amount of water in the bucket, and even the atmospheric pressure.

For example, in places with high atmospheric pressure, because the air density is high, the water is affected by air resistance when falling, and the dripping speed is much slower than in the low-pressure environment of the plateau.

In this case, the same set of drip timing tools will naturally be inaccurate if taken to the plateau area.

Of course, what we can see is that in plateau areas, due to the low air pressure, the speed at which water droplets fall is fast, so the speed of time flowing in plateau areas is faster than that in plains!
