So... Just turn a blank round into a live bullet...

Maybe we can fire it at the planet that keeps sending those asteroids that nearly hit us.

[–] Hupf@feddit.de 25 points 10 months ago

Why yes, I would like to know more.

Excellent analogy, but now I want the math. Think we could push this past the gravity well? Fuck space elevator, I got ejecto-volcano cuz.

[–] Scubus@sh.itjust.works 10 points 10 months ago

I would imagine very small section might be able to? I know one of jupiters moons has geysers that shoot water into space and out of orbit.

Isn't a space cannon or whatever it's called a very old sci-fi idea?

It's like the oldest, it's how Jules Verne sent men to the moon in "From the Earth to the Moon"

Pretty much as soon as a cannon got invented and shot, some guys were like "...maybe we could shoot ourselves out of that..."

New idea: build a small town on top of the block that's placed on top of the vulcano and start exploring space(and colonise other planets).

Apparently launching a metal cover with a nuclear weapon might not even be enough to reach space

Very rough Google math (mostly because of "fuzzy" answers on the energy required and how you define space) suggests that the 1980 Mt St Helens eruption had enough energy to orbit three billion kilos...

I based that on the eruption being rated at 24MT, which converts to 100b MJ, and a minimum of 30MJ/kg being enough for orbit. Didn't find a straight answer on escaping the gravity well, could be way higher.

That doesn't seem right to me, but that eruption did, in fact, move the entire top of a mountain a pretty silly distance, so as ridiculous as it sounds, it could be accurate? I mean... 500 billion KGs of ash was spit out of it...

That's the most terrifying thing I've ever googled i think. I feel like I don't actually want to know the actual math on this. It's fucking plausible dude.

I'm pretty certain that it would destroy whichever object was launched. The air friction alone would tear it apart.

Or a cheaper space program.
