One of its most famous aspects concerns objects moving at the speed of light.  Simply put, as an object approaches the speed of light, its mass becomes infinite and it is unable to go any faster than light travels. This cosmic speed limit has been a subject of much discussion i...

The kardashev scale (Advanced civilizations)

Image
First of all to get kardashev scale we have to learn about Dyson sphere. Because Dyson shpere has some connection with these civilizations. Let's learn Dyson sphere -Dyson sphere- In 1960's a scientist called freemendyson has told that sun will release 3.8×10^26 jouls per second in all that the directions.  But our Earth 3.9×10^20 jouls. It Means earth takes nearly the engery given by the sun at 1second. And for this to get all the sun energy, freemen Dyson has told that he has created a sphere called Dyson sphere. In this Dyson sphere we have to create a sphere like settings around the sun and receive all the energy. And also to do this Dyson spheres we are not having much technology to do that. And also we can say it's Impossible with our present technology Now let's go to kardashev scale -Kardashev scale- Kardashev is a Russian scientist. He has told 3 future civilizations for a planet –Civilization type 1–: This is also called as planetary civilization in this Civil...
