The Kardashev Scale

As technology advances with more and more energy used, a soviet astronomer named Nikolai Kardashev, came up with a method to determine a civilizations technological advancements with the amount of power that is accessible to that civilization ( in watts ). Originally, this scale uses three categories but over the years it’s been modified with adding other categories but in this article, we’ll only go over the four types.

The Kardashev Scale can go beyond Type IV but it’s highly unlikely for humanity to reach these types. Source:https://www.youtube.com/watch?v=rhFK5_Nx9xY
  • Type II: A Type Two civilization can be known as a stellar civilization having the capability of controlling all of the energy from its solar system. This civilization would consume 10²⁶ w of energy. This type of civilization would be capable to change who they are with the ability to read and engineer their genetic code. Concepts like the Dyson Sphere with encapsulating their home star is out of this world! Literally!
  • Type III: A Type Three civilization, also known as a galactic civilization, would be able to control all of the energy its host galaxy has to offer. This would be around 10³⁶ w of energy. This type of civilization is capable of manipulating molecules and molecular bonds creating new materials. This is every Star Wars/Star Trek fan’s dream of our civilization reaching this level!
  • Type IV: A Type Four civilization, which could be known as an intergalactic civilization, has the ability to control all of the energy it’s whole Universe has to offer! Consuming around 10⁴⁶w of energy! This type of civilization would be able to manipulate individual atoms and creating complex A.I. ( The original scale does not include a Type IV due to the speculation of it being impossible) Alright this civilization is god level!
Kardashev Formula

K = Type

P = Power a civilization uses (watts)

Using this formula, if we input the global amount of energy used which is about 18.40 TW or 1.84 × 10¹³ W, we’ll end up with a Type 0.73 civilization. Not yet a Type I civilization but in a few hundred years we’ll definitely make it to Type I! This is a surprisingly simple equation to determine how advanced a civilization is. You may now be thinking, “Wow! There must definitely be life out there” and this is where the Drake Equation comes into play.

Drake Equation

The Drake Equation (not the singer haha) was made by an American astronomer and astrophysicist Frank Drake in 1961. This equation’s solution gives you the number of intelligent civilizations out in the Milky Way using 7 variables:

These variables can be hard to attain since some of these numbers we don’t know and are using estimates with what we know. Source: https://www.lsntap.org/node/207/webinar-drake-equation-access-justice

Fermi Paradox

The Fermi Paradox was created by Enrico Fermi, an Italian physicist from the 1950s who made a lunchtime remark that holds the attention of multiple astronomers and scientists today:

“Where is everybody?”- Enrico Fermi

So simple but yet so deep! (*brain thinking intensifies*) The Fermi Paradox is the apparent contradiction that the Universe seems so empty with no life at all but with the high possibility that life out there does exist! There are around 10,000 stars for every grain of sand on Earth, the Universe is around 90 billion light-years in diameter, and has existed for more than 13.8 billion years! Surely someone should’ve answered our calls! Below are some thoughts and possible ideas to why:

1. The Limits of Humanity

2. Communication

Communication is a possible barrier to discovering aliens! Source:https://www.youtube.com/watch?v=1fQkVqno-uI

What’s the reason to explore?

Key Takeaways

Awesome! You just finished this whole article(more like finished frying your brain)! Or you just want to know the basic summary of this article, so here you go:

“Two possibilities exist: Either we are alone in the Universe or we are not. Both are equally terrifying”

— Arthur C. Clarke

With the existence of extraterrestrial life, it could mean some bad news for us, it would be comparable to Christopher Columbus landing into the Americas making contact with the Native Americans. In this case, if we were visited by a super-advanced civilization from the cosmos, we would be the Native Americans, and we know how that played out and also in multiple sci-fi movies. But knowing that we are alone in Universe, leads into seeing that it’s as if we’re not supposed to exist and that the Universe is dead, which means we’re the only hope for life to exist out there in the Universe. It gives us a responsibility to explore and experience the quiet but beautiful Universe and to continue the delicate flame of life.
