Could aliens destroy us from light years away? Another day at Kurzgesagt Labs, where we answer the most important questions with science.
Today: how might civilizations wage war across light years? What kind of devastating weapons could they use and what would they look like?

Wut
War 0:00
Thank you Kurzgesagt, I was planning to wage an interstellar war soon, this will surely be helpful
Bro is goin to do it
against who?
ok who we fightin
İm ready
What about the Droid attack on the wookies ?
For anyone interested, the bookseries of “Trisolaris” briefly, and “The Forever War” more intensely deal with the concepts of interstellar warfare.
You mean “remembrance of Earth’s past?”
@gomshom67 You’re right! Trisolaris seems to be the name for it where I’m from, but not the actual name of the series.
Charles Pellegrino’s “The Killing Star” is also worth a read. Several of the ideas in the Remembrance of Earth’s Past series came from that novel.
Alternatively, the Dune series… if you want the really weird, perverted answer. The answer is not in “the Spice.” It’s in the theoretical “Golden Path” which is essentially “spread far across the universe, mutate, evolve, and get so weird that even humanity as it exists can’t predict what you might do.”
I want to do a skibid toilet episode
An interesting idea from the Bobiverse series of books: If you shoot a nuclear missile at relativistic speeds, after detonation the resulting EM waves get red-shifted into even more damaging gamma radiation. It still doesn’t have a planetary area of effect (for that you’d need to scale up to more warheads), but it allows a single warhead to be directional and much more fatal to all life. The advantage here is that you only need to accelerate a relatively small payload, so you don’t need a skyscraper-sized missile.
The waves would not be shifted, they are the result of the collision and do not travel at the speed of the object. But if you sent an emitting body, then yes that could happen and would multiply the energy of the emitted particle
@Adrien Foulon There would be no collision. The missile detonates before reaching its target.
Maybe I missed something but in the video we also have small payload, just 300kg. Rest is huge fuel tank so our missile get enough speed
@Damian Waluszko The relativistic missile is a purely physical weapon, simply having an insane momentum due to its ridiculous speed and thus a devastating impact. This idea is more like the ultra-relativistic electron beam in that the “killer” is high-energy particles that break down DNA.
You mean blue-shifted?
An interesting follow up video would be how a more advanced humanity might defend against such existential weapons.
Agreed, I was just thinking about that.
The quallity of the animation has increased a lot! I love this! And the way Kurzgesagt explain things to us!
it’s a team of professionals
@A UFO’s Lab Indeed!
I’ve always thought that there’s nothing to fear about hostile more advanced aliens. If they strike we won’t even see them coming
Good
I love how instead of deciding to help humanity build the weapon, kurzgesagt instead decided to help the aliens
Yeah what is the name of that very alien you mentioned? Oh yeah Israel
@aliya wahid cry to your dictator
Atleast we were not the villains
It’s because they know creating existential dread gets clicks.
Fun fact: The background’s audio of Kurzgesat’s videos can tell you the whole story by itself! So much quality!
Yeah it is a remix of one of their older tracks
Yep it’s the remix of the audio from the Dyson sphere video, really awesome track!
The most interesting of the three was the ultra relativistic electrons. If you could get a spaceship to a speed like that, humans could settle on other galaxy groups.
Don’t forget about acceleration and deceleration, you don’t want to turn into a puddle.. But you might not need the deceleration part if you settle next to a black hole, the acceleration part though is not optional, and so it would still take you years to reach a speed of “just” 99.99% the speed of light, remember the unit of acceleration is m per second per second (yes second squared) and the faster you go, the slower time (or the smaller the meters, you chose the reference frame) and thus the less effect your acceleration has towards the speed of light while still having the same effect on your body
I seriously doubt any vessel that could carry human beings and the necessary equipment could ever get that close to LS.
Our only true hope is warping and whilst that is physically possible, it is practically absurd.
In the book series Remembrance of Earth’s Past, humans develop an ultra relativistic spaceship to travel to the heat death of the universe for science in a single lifetime. It was acknowledged to be suicide but was done out of curiosity
Along with a massive boatload of other technology
