This reminds me of that quote from Mass Effect:
"This, recruits, is a 20-kilo ferrous slug. Feel the weight! Every five seconds, the main gun of an Everest-class Dreadnought accelerates one to 1.3 percent of light speed. It impacts with the force of a 38-kiloton bomb. That is three times the yield of the city buster dropped on Hiroshima back on Earth. That means: Sir Isaac Newton is the deadliest son-of-a-bitch in space! (...) I dare to assume you ignorant jackasses know that space is empty! Once you fire this hunk of metal, it keeps going 'till it hits something! That can be a ship, or the planet behind that ship. It might go off into deep space and hit somebody else in ten thousand years. If you pull the trigger on this, you are ruining someone's day, somewhere and sometime!"
141Responding to the last comment in the image:
You could literally just do reverse Starship Troopers, the movie at least.
You're a bunch of aliens and blam out of no where the nuclear launched manhole obliterates a holy site on your homeworld, your scientists track the trajectory back to Earth, conclude they must have launched it intentionally, and then launch an interstellar jihad against totally unaware Earthlings.
38The calculation of its speed was made by high speed camera, as you've probably seen the Mythbusters do. In this case the manhole cover was seen in flight in precisely one frame of high speed camera footage, and for it to go "installed, in flight, gone" in three frames means it would have had to be moving at mach jesus.
It likely didn't make it to space intact; it would have had ultrasonic compression heating on one side and a nuclear explosion on the other. It's probably still here in the form of iron oxide dust scattered about the Northwestern hemisphere.
26I love the idea that our first message to aliens might be "FRESH WATER ONLY. NO WASTE."
19Tl;dw: Vaporized
19Surprised no one has posted this but Kyle hill made a video on it
15The foundry that made that manhole cover has some great potential advertising claims.
9One thing that no one ever talks about with this is the massive air resistance on it going Mach 164 through the atmosphere would incur (albeit for a very brief period)...I bet that would knock 25-50 kmph off it easily.
8Ok, tin foil hats for this one, our universe isn't exactly infinite in the way people traditionally think like numbers. The edges of the universe bend and form a large shape, say a sphere for simplicity. That cover speeds through and circles back eventually, but do to it's speed and travelling along the edges of everything and relativity, when it returns it's not at the same point or even at the same speed. It arrives before it initially left, quite a bit before it left... So much so that it kills off the dinosaurs.
8How to solve the Three Body Problem.
7Most likely it just evaporated, or disintegrated or something, but I think its pretty unlikely it survived that absolutely bonkers acceleration.
7The Parker Solar Probe moves 120 miles per second as it passes around the Sun. That's nearly half a million miles per hour!
6In Stargate SG1 they do that to destroy and invading alien ship approaching Earth.
4So has it been replaced ?
3Maybe it desintegrated and thus vanished from the consecutive frame?
Atomic blasts are kind of powerful versus an iron lid.
1Man. I haven't seen an ifunny logo in so long. Are people still on it?
1Any time this comes up I'm reminded of this little interaction in Mass Effect 2:
1Fact check , some of those comparisons were wrong. https://chatgpt.com/share/674ffea4-35e8-800a-8e9a-555180b4c18c
