What is Kardashev Scale? - Science Feed

Have you ever imagined what is the sheer scale of our universe and how the future of human civilization is. There is scale of things that can be framed in and outside of our Universe. In this article, we have discussed the same curious question.

Kardashev Scale is the method by which we measure scale of a civilization about their technological advancements, developments, scale etc. is based on the amount of the energy being used. 

This was proposed by a Soviet era astronomer Nikolai Kardashev in Byurakan Conference 1964 inside the article of Transmission of Information by Extraterrestrial Civilizations. 

Type I, II and III are the original types by Nikolai Kardashev. There are others types too since these three are not enough for complete explanation of civilization's scale.


Type 0 Civilization

This type of civilization is not able to harness and use energy levels of 4×1012 watts/sec, basically less than that. In other words, the civilization must be able to use all the light received from its Sun, parent star. Currently, not exactly but close, we are near Type I but still in Type 0. There can be controversy on this statement.

Type I Civilization

Type I Civilization is able to use all the light or energy falling on its home planet from its parent sun. So, we can say 4×1012 watts/sec is consumed on average. We are pretty close to achieve this amount. Carl Sagan says that Type I Civilization will be achieved around 2100.

Type II Civilization

For Type II Civilization, it must be able to harness the amount equivalent to 4×1026 watts/sec and use it simultaneously from its parent sun. For getting this marvelous engineering architecture, few design has been proposed in scientific community that is: a Dyson Sphere which surrounds the Sun all around like numerous rings or a Matrioshka Brain which also surrounds the Sun small plates at different distance from it.

Type III Civilization

Type III Civilization is supposed to farm the entire galaxy for its immense requirements. The amount is approximately equal to  4×1037 watts/sec. This type of civilization is predicted to be found somewhere around the center of our galaxy.
It has been called that Type III may capture upto 75% of the light emitted by the galaxy using Dyson Sphere type structures.

Type IV Civilization    

Type IV Civilization is beyond Kardashev's comprehension. According to Zoltan Galántai, the Type IV civilization will be able to harness energy of the entire energy and possess the divine capabilities of manipulate universal laws at their own will. This scale is defined to be around 14 billion parsecs.

Type V Civilization

Whatever the possibilities are left that can be defined in Type V Civilization. It was brought up by Carrigan. These civilization may have control over multiple universes and exist anywhere in the realities beyond our imagination.

There are even more theories related to the explanation of scale and advancement of the civilization. It is in the minus scale also. There have been new discoveries related to this topic by means of latest deployed telescopes.

How does a NPU, Neural Processing Unit, works? - Science Feed

By
A NPU (Neural Processing Unit), also knows as AI accelerator, is a computing unit specially designed for the running artificial intelligence and machine learning models efficiently and effectively on a single motherboard with other computing units.  There has been significant rise in the use of NPUs in personal devices like smartphones, laptops, PCs etc. to do personalized recommendations and offline AI processing.  NPUs are capable of parallel processing, low precision arithmetic, hardware acceleration.  These have silicon architecture to kind of simulate the human brain working like human where instruction set of AI efficiently ran. NPUs are not for computing traditional problems as it lacks important physical capabilities. Because of these, AI systems are able to learn faster without wasting time and energy. The parallel computation feature give wings to matrix operations ease, activation functions of neural networks, dot product.  NPUs have got dedicated compute ...

What is Dark Energy? - Science Feed

By
There are different forms of energy. But, there has been speculation of an hidden form of energy that has been kind of hiding from us which constitutes a large part of our universe.  The universe has been found to be expanding faster than the speed of light. The traditional form of energy that we have found has been to be not able to provide that much of push. So, there must be something. This type of energy is called Dark Energy. Dark Energy is that form of energy that is not understood by us but it is fundamental in nature and drives the process of the universe. In Theory of General Relativity, there is concept of cosmological constant which says there is a negative of gravitation or empty space that is all over the interstellar space.  The researchers of DES and others have found that the universe is expanding not alone of known form of energy but some mysterious form of it. This is also related to Big Bang. Dark energy is told to be constituent of 68 to 70% of total univer...

How are LIDARs changing field of Robotics - Science Feed

By
In the field of robotics, there is crucial role of sensors out of which the LIDARs (Light Detection and Ranging Sensors) are very important.  LIDAR sensors send the light and detects back the reflected light from any object to estimate how much far away the object is based on the calculations. Laser is used as primary light source as it can bounce back on most surfaces. These are used to make maps of the area where the robot will move around for navigation.  There are different kinds of LIDAR sensors like 1D LIDARs, 2D LIDARs, 3D LIDARs and even 4D LIDARs.  1D LIDARs are most basic type of it because these emit laser in one direction at a time and a point for point cloud is created. A point cloud is a group of large number of points that create map of the area. 1D LIDAR then moves in other direction and make different point after that.  2D LIDARs are the better version of 1D LIDARs as if you are rotating the 1D LIDAR in continuous rotation to project it in a circular...
