Did scientists find Dyson spheres around stars? Neil deGrasse Tyson explores what an alien civilization might look like to us, the Kardashev Scale, and Dyson Spheres.
Learn what researchers found around previously discovered stars. We break down the Kardashev Scale and what to look for when detecting alien civilizations. Plus, learn about Freeman Dyson and how he thought a Type II Civilization might work.

Bro, you are not pronouncing kardashev right
Why there is always a Kardashian involved
I’m very curious now about the paper Dr. Tyson references. My first question is why heat is considered waste energy. Would a Type II Civ not capture that heat using technology heretofore undiscovered by this, our Type 0 Civ? Even a Type I Civ should be capable of capturing heat energy if we say they have achieved the means to harness the power of a planet. Much of the energy of a planet exists in the form of heat.
“ If we could control that “ Those words seem to be a thing for humans. The thing is, humans need to control their ego & selfishness, imagine that.
“the simplest, most elegant explanation is usually the one closest to the truth”. – Occam’s razor.
Aliens that can use the entire energy of their solar system or some gas clouds, probably the gas clouds.
We are not even type 1 yet and they think they have enough materials bigger than earth and need millions of it to cover our local sun? Lol not likely.
What’s your problem man ?
