Chapter 561: Quality detection

I saw a black hole about the size of a fist appeared in front of Yang Chen.
When all the light reaches the black hole, it seems to be completely swallowed, and it is completely invisible.
"Is this really a black hole?"
Yang Chen was not sure.
In addition to absorbing almost all light, black holes also have other characteristics: for example, super gravitation, all the objects and light that are drawn into the black hole, and the horizon of the black hole, strong X-ray radiation and thermal radiation.
However, when Yang Chen switched to the perspective of psionic energy, he could not see that the so-called "black hole" had any characteristics other than engulfing light.
It does not have super gravity, nor does it have a field of vision like a solidified image wall surrounding a black hole, nor any X-ray radiation or heat radiation.
You know, with the powerful gravity and mass of a black hole, even a fist-sized black hole can create a terrible disaster on the earth-it may even devour most of the earth's mass!
But none of this happened.
"Is this not a black hole?"
Yang Chen wondered.
For celestial bodies such as black holes, there is currently no direct evidence, only indirect evidence and theoretical basis-and most of them are unproven theoretical foundations that are only established mathematically. Its biggest theoretical basis is Einstein's general theory of relativity, and there is no more.
Therefore, the specific appearance of a black hole is not necessarily based on the characteristics inferred by scientists on earth. But no matter how different, at least not completely different.
So Yang Chen felt that this should not be a real black hole, could it be just a black body?
The so-called black body is an ideal object that absorbs all external electromagnetic radiation without reflection or projection. Light is originally a type of electromagnetic wave, so the black body will devour the light. In contrast, the black body should be closer to the thing in front of Yang Chen than the black hole.
"and many more……"
Before Yang Chen finally came to a conclusion, he was using the psionic perspective to suddenly discover something new:
"This thing... this thing seems to be in a strongly twisted space. It is not devouring light, but it is in a strongly twisted space, so that all light passing through this space cannot leave this space, but is twisted in this space. Looping back and forth in space and never flying out!"
What is the computing power of Yang Chen now? With just a little calculation, the pupil dilated instantly, which was a shocked look:
"If according to the present degree of spatial distortion, then according to the theory of relativity, this means that this thing will have at least...have at least a tenth of the mass of the galaxy!"
This result surprised him all: "This... how is this possible?"
Before the strong spiritual power extraction, Yang Chen's spiritual power was already exhausted. It's just because his cultivation level is too low, but the state is too high. The speed of recovery of this spiritual power is unimaginable. Now he also has almost full state (with the current cultivation practice) of spiritual power.
So he released a spirit spell: "Quality Detection!"
This is a relatively rare but magical skill that can often come in handy at critical moments.
This spiritism is only second-order, but on the battlefield, it often has a very important role.
That's right, as its name suggests, this is a spirit technique used to detect mass. It can detect the quality of all objects existing in space, regardless of whether you can detect this object.
That is to say, if there is an object invisiblely approaching you, then even if you cannot detect it with your eyes, electromagnetic waves, psionic waves, etc., you can’t find it, but as long as it really exists in this world, it has mass, Then it will be able to be discovered by your quality detection.
In combat, this method can effectively warn almost all stealth attacks: any stealth method, whether it is optical stealth, electromagnetic wave stealth, psionic wave stealth, or even higher subspace stealth, phase space stealth, etc. Wait, as long as it still exists in this world, or that it intends to have an intersection with the real world, then there must be quality, and it must be discovered by quality detection.
Of course, if you do not intend to intersect with the real world, it is equivalent to being in a universe independent of the real universe, and mass detection is indeed invalid for you. But in that case, you can’t touch everything in the real universe: you can’t see the light of the real universe, you can’t hear the sound of the real universe, and you can’t make any attacks or other actions on the real universe, then you run invisibly. What are you doing here? It's completely useless.
All in all, quality detection is of great use in later generations. Not only is it useful on the battlefield, it is also useful when engaging in scientific research, and even more useful. Of course, it is not easy to use well: everything in the world has mass. If you want to detect whether a specific target mass exists, you must first eliminate all ubiquitous non-target quality interference. This requires not only high accuracy, but also powerful computing power and algorithms to be able to find quality data representing the target among the vast detection results.
This is already quite a professional thing.
The quality detection spirit is only second-order itself, but its algorithm and high-precision detection method can only be mastered by monks with at least a fifth-order satellite! The importance of this algorithm and high-precision methods can be seen.
This is not a problem for Yang Chen now.
If there are no errors in his calculations, this thing that does not know whether it is a black hole or a black body will have a mass equivalent to at least one tenth of the Milky Way. Such a massive mass, no matter how, the spirit of mass detection cannot be ignored, and its data cannot be hidden: because that data will be very special, it will be a huge astronomical number, anyone can recognize it at a glance .
The light of the spirit spell representing mass detection flashed through, it was a white light that appeared to fall on the suspected black hole, but just flashed once, and the light was destroyed.
"What's going on? The theoretical basis of mass detection lies in the lowest physical laws, so its detection may be misleading and disguised by various means, but it is impossible to invalidate it. But what it just looks... is clearly a mass detection spirit. It's broken!"
Yang Chen was very curious, and suddenly remembered something, and suddenly the flash of light flashed: "Wait, I just used the active detection habitually. This detection method needs to actively release the aura to scan the target, which is easier to detect. Those smaller masses-as long as there is mass at the target location, it will inevitably disturb the detection of aura, then all invisible targets can be discovered as long as there is mass."
However, this technique is only applicable to the battlefield. Because the presence of detecting aura will inevitably cause disturbance to the target, or the quality of the target will inevitably disturb the measurement of the aura. In short, it can find that even if only a milligram or less of quality disturbance can not be accurately detected The precise quality of the target itself that caused this quality disturbance.
On the battlefield, this does not matter. Because this is fighting, not researching, the most important thing is to discover the invisible enemy, not to study whether the invisible enemy’s precise mass is one milligram more or one milligram less—there is no fundamental impact on the situation. to.
Moreover, to measure the precise quality of the target, the amount of calculation is also very large, and calculation also requires constant time. On the battlefield of time and time, there is no American time to slowly let you count.
Therefore, the technique on the battlefield is definitely inaccurate, and it is only fighting for time: I only need to find you earlier and be prepared for the invisible enemies, it is enough. It does not matter what invisible means this invisible enemy uses and the exact value of its own quality. It doesn't matter at least during the battle. Specific research can wait slowly after the war, but it can't be ignored on the battlefield.
Of course, quality detection is an important spiritual technique, that is, it has both active detection techniques and passive detection techniques. This technique is more accurate.
Yang Chen has been active on the battlefield in later generations, so he unconsciously released active detection techniques.
But even with his rich experience, the Trojans have emerged in an endless stream of stealth attacks that can almost be imaginative, but there has never been a situation that can actually lead to active quality detection failure.
Immediately after the reaction, Yang Chen changed the detection method to passive quality detection.
This time ~EbookFREE.me~ only his aura flashed faintly, and no aura was released: passive quality detection will reflect all the qualities within the detection range in full detail, and detect all, if not right Scientific research projects that require extremely high accuracy are really not useful.
The key is that the data in this way is extremely massive. Because the mass data of all objects with mass response on the earth will be detected. Do you think it is just the quality data of all objects within the detection range? No, of course not.
You have to know that because of the existence of gravitation, the gravitational response of all objects with mass in the universe can theoretically be found on the earth-that is, it can be detected by mass detection spirits.
Of course, in fact, the mass response that can actually be detected is either not too far from the earth or far away from the earth because of the excessively wide distance and the loss, interference, etc., but its quality is on the order of magnitude.
But even so, the large amount of data that can be detected, for a moment, still allows Yang Chen, who has the essence of planetary order spiritual power and even the powerful fortune teller, to feel that his brain seems to be brutally hardened by something. It's very stuffy, for a time the headache is split, Venus stares, and the brain instantly loses its processing power. (To be continued.) To find this site, please search for "" or enter the URL:
