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?

Thank you Kurzgesagt, I was planning to wage an interstellar war soon, this will surely be helpful
-
I love how instead of deciding to help humanity build the weapon, kurzgesagt instead decided to help the aliens
-
"planning a hyper-space bypass through our solar system" I see a Hitch-Hikers Guide To The Galaxy reference, and I like it!
-
The three body problem is the greatest series of novels I have ever read to do with alien invasion. Read this series and instantly double your perceived imagination of space. It's that mind blowing. I highly recommend it.
-
If the aliens sent a message like "Surrender within 24 hours or face destruction" we could send a message back "Is that 24 hours in your time or our time?". Considering the distance involved, we could gain millions of years of extra time just by trying to sort that out.
-
If you sent a pebble fast enough you’d be able to destroy an entire planet
-
“The bigger it is, the longer its range.” Didn’t think I would be able to take a kurzgesagt audio bit out of context.
-
Imagine waiting 84 years just to hear that your intergalactic weapon hit a random planet that was in the way.
-
So fascinating to learn that humanity is completely defenseless to advanced hostile aliens in at least three different ways!
-
Absolutely loving how with the Electron Beam you can hear the narrator carefully counting each '9'
-
Love how you's went full "3 Body Problem" in this video 👌🏽
-
This would honestly be such a great idea for a show
-
An interesting follow up video would be how a more advanced humanity might defend against such existential weapons.
-
I love that I've grown up to Steve Taylor. He has such a calming, yet captivating voice!
-
Helldivers pay close attention

Lesson 1: don't attack from your home base. Use another star as your attack base. If anyone retaliates, they attack right into your honeypot, revealing themselves. Welcome to interstellar war. Interstellar assassination with rockets: You don't have to go relativistic from your home base. Use light sails at the outskirts of your home star's corona to accelerate to 0.1c and go for a somewhat nearby white dwarf (not too near). Use the flight time to assemble the rockets underway. This should be possible totally unseen and costs just a couple of years more. That's totally unimportant since nobody knows about you anyway. At the white dwarf use an Obert maneuver going relativistic. The direction of attack is changed because of the gravity of the white dwarf (that's one of the reason's for the Obert maneuver, the other is the masking of the drive's radiation), masking the true origin of the attack and since the Obert maneuver is happening very near to the surface of the white dwarf everybody thinks this is a normal astronomical event on the surface of the white dwarf. You don't have a cooling problem because of the vicinity of the white dwarf since you have the technology to cool your rocket from the immense radiation of your drive which should be very much higher than the radiation coming from the white dwarf, so that's not a problem. If necessary you could even fake a real astronomical event using your antimatter. Nothing points to your home base. If anyone figures out anything it should be clear to them that the home base couldn't be have been the white dwarf and they remain silent.

After finishing ‘The Dark Forest’ by Cixin Liu, every science video suddenly feels different. I’m seeing the universe in a way I never did before.
