** [[http://en.wikipedia.org/wiki/Tsar_Bomba Tsar Bomba]] being a [[BigBulkyBomb 50 megaton atomic bomb]] that the Russians let off during the UsefulNotes/ColdWar, the largest ever tested. Could have been 100 megatons on paper, but the Russians were concerned about fallout and the fact that the plane dropping it wouldn't have escaped the blast radius even with parachute retardation, so it was scaled down for the one that was made and detonated. [[note]]: Most early airdropped atomic weapons had parachutes so that the drop plane could get out of the blast zone of the weapon. Since this affected the aim of the bomb a lot and generally let them drift off target, the bombs had to have massive yields to ensure that even being off-target by a few miles wouldn't matter too much due to the massive blast radius. The invention of [=ICBMs=] and reasonably accurate delivery of warheads allowed for nuke yields to scale back to less overkill[[/note]]

* Supernovae, where an entire star is blown up to kingdom come, either after accreting too much matter from a companion and inducing a runaway nuclear fusion (Type Ia) or after ending up with an iron core -which cannot be fused to release energy-, and the star's remaining layers collapsing over it (the rest).

To give a sense of scale, a star going supernova can briefly outshine the ''entire galaxy'' it's in (consisting of hundreds of thousands to hundreds of billions of stars or more.)

* While extremely ambitious, Someone at the Chinese space program didn't get the memo that reusable rockets are meant to be launched in places where the boosters can be recovered safely. At first, this was due to geopolitical concerns - launching rockets in the East where they'd fly over South Korea and Japan isn't exactly a good idea - as tensions have slightly relieved themselves, construction work on new spaceports is still slow going. This ultimately means that the Chinese administration has adopted an 'out of sight, out of mind' mentality to rocket launches, even if that means [[https://www.youtube.com/watch?v=VFyFpo3iTqc villages in the Chinese countryside get flattened in a huge explosion in the process.]]
