There is one detail wrong in the first post; that is not the lids speed but rather it’s minimum speed.

Responding 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.

That reminds drag of Halo, though significantly more silly.
In Halo, the Covenant are on an interstellar crusade for holy artifacts left behind by the Forerunners. When they discovered the planet Harvest, inhabited by humans, they saw tons of artifacts on their scanners. So naturally, they landed on the planet and started blasting the humans to steal the artifacts. But the more humans they killed, the more artifacts disappeared from their monitors. The humans must be destroying the artifacts out of petty spite! What heresy!
The Prophet of Truth is curious about what kind of artifacts the humans have, so he goes to talk to an ancient Forerunner AI they have in storage, Mendicant Bias. Truth shows Bias the symbol that they keep seeing on human worlds. Bias says “You fool, you’ve got it upside down. Turn it around, see? It says Reclaimer. It means a person the Forerunners have chosen to inherit their empire. You’ve just been killing these humans? No wonder the reclaimers keep disappearing, you’re the one who’s doing it!”
So Truth realises that he’s been ordering his troops to kill what should rightfully be considered demigods by his religion, and who he should be worshipping. And he realises that if he reveals this information to the people, he and the other Prophets will lose all their political power since there are Actual Fucking Gods walking around. So naturally, Truth declares a Holy Genocide against humanity so that nobody will ever figure out that he’s guilty of Deicide and that their entire religious political structure is a lie.

Or, you just decided on first contact, but, suddenly, ship goes boom after being struck in the propulsion system with a bullet like manhole cover.

I love the idea that our first message to aliens might be “FRESH WATER ONLY. NO WASTE.”

Nope, it would just have bursted due to thermal schock and pressure. Escape velocity, what are you dreaming, is the lid made of tungsten?

Hypersonic heating is really weird. We only have data going to about mach 17 (the HTV-2 was the fastest solidly atmospheric vehicle I found) but as we go from subsonic, to supersonic, to hypersonic regimes air becomes pretty much incompressible, and forms a really solid shockwave in front of a fast-moving object. Air is a pretty good thermal insulator, so for very fast, blunt objects they actually heat much slower than you might expect.
Tl;Dr it absolutely vaporized, but it likely lasted longer than you might expect.

We should test this again, but with a fridge and someone inside it for the nuclear blast. I bet that would work out great

Ok, 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.

Sadly, the escape velocity of our galaxy is an order of magnitude higher than the manhole cover’s velocity. And even at that speed it wouldn’t hit with nearly enough energy to cause a mass extinction. Still a fun idea though. :)
- IrritableOcelot ( @IrritableOcelot@beehaw.org ) English8•13 days ago
One 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.

Most likely it just evaporated, or disintegrated or something, but I think its pretty unlikely it survived that absolutely bonkers acceleration.

The Parker Solar Probe moves 120 miles per second as it passes around the Sun. That’s nearly half a million miles per hour!
- Comment105 ( @Comment105@lemm.ee ) English1•11 days ago
Parker Solar Probe: 191 km per second.
Nuclear Manhole Cover: 55 km per second
Voyager 1: 17 km per second
Voyager 2: 15 km per second

The foundry that made that manhole cover has some great potential advertising claims.

Fact check , some of those comparisons were wrong. https://chatgpt.com/share/674ffea4-35e8-800a-8e9a-555180b4c18c
Don’t use gpt to fact check.

The escape velocity for the solar system and from Earth’s surface should not be the same. This is why you should always double check anything ChatGPT says.
