More Kurzgesagt reactions please! There is so much more existential dread to experience.

I recommend the "What if...?" series for more creative ways to destroy everything.

Now imagine being on the I.S.S. watching the ultimate nuclear event happen, and slowly realize you're never going back home to earth.

I wonder if their video takes into account blast wave interactions. A single nuke with the same combined yield as many smaller nukes would only create one single explosion, as opposed to many individual ones, and I feel like maybe a lot of force would be lost as the blasts interact with one another - but I'm no physicist so...

<a href="https://www.youtube.com/watch?v=J1SR6wpH7CM&t=614">10:14</a> Yes please! Two Kurzgesagt videos I would recommend are ‘what if we nuke a city’ and his video on how interstellar aliens could annihilate us

If you like this video you should REALLY watch their video "what if we nuke a city?" It details the horrendous and devastating effects of one singular nuclear blast in a populated area, including going into great details regarding the aftermath and how difficult it would be to send aid and what would happen to the people in and around the city. It's truly a chilling video, because unlike this one, it depicts something realistic that could actually happen and what the consequences of it would be. I've never been able to watch it without starting to cry.
