i hope someday we construct a collider that spans the entire circumference of the earth. But we'd probably have to build one that spans the circumference of the moon first, and then maybe mars, since the oceans are going to be a bit of a doozie to work around that we don't have the technology for, whereas the interior of a collider is supposed to be evacuated, so, the moon almost kinda already handles that for us. heat might be an issue of course, but if we can figure out thermal radiator panels that can dump the heat straight into space, maybe we could pull it off...
mars would address the heat issues, but those dust storms are no joke and the dust itself is microscopic toxic/caustic razors and it'll try to get in everywhere and ruin fine instruments it touches. Moon dust is also really bad but there's no wind to kick it up on the moon obviously...
but damn. DAMN. imagine the fucking science we could get done with a LUNAR-SCALE PARTICLE COLLIDER!!!
Halo
Just gonna throw that out there
Master Chief, we need you for one last mission >!bro!<
Fuck it, orbital collider. Earth deserves a cool ring
Yes. Encircling the Sun
queue halo theme
Gotta build it as an orbital ring.
Also, maybe add some biomes, oceans and wildlife. And absolutely no parasitic life forms trapped in there.
Hear me out okay. hits blunt Dyson ring. Maybe we start building it out between earth and Mars. We dig a big ass hole into Mars core and use some kind of laser technology to focus radiation into it perhaps "jump starting" the core. Or maybe we use some kind of cable and gymbal system to run a hard wire into it. hits blunt Then meanwhile we're crashing comets and shit into it to get us some oceans and atmosphere, badabing badaboom we got earth 2.0
You should put that blunt down, buddy.
never.
Well check this out: if it's big enough and can collect enough solar energy, it can be a self-powered gargantuan electromagnet and CREATE a magnetosphere for Mars itself. And the moon has a higher silver content than earth, which a) won't tarnish in the vacuum of space and b) is more conductive than copper or gold!
Aluminum alloy structures, silver circuitry, we could build this thing without sending ANY of it's raw materials from earth. It's all already up there waiting for us... ... Some assembly required :p
I'm sorry I'm just now seeing this reply because that is fascinating
The Moon’s daytime is half a month long and can reach 120 C so we’d need some pretty powerful heat shielding. And there’s no ozone layer to protect the electronics from radiation, and I’m pretty sure the Moon orbits outside of Earth’s magnetosphere. And the shielding used for such a project could also be used to fix climate change here (and terraform Venus later) with orbital parasols. And whatever unimaginable technology we’d need for such an ambitious project may as well be used to run a grid of electromagnets and power lines across Mars to give it a magnetic field
Most proposals for moon colonies are either built underground or covered up with a thick layer of regolith for both of the reasons you mentioned. It's very likely a collider would also be built underground for the same reasons. Digging a many-miles-long tunnel on the moon with the awful properties of moon regolith to deal with would have its own set of challenges though.
Yeah. I hear NASA and India are planning to send 3d-printer robots to lava caves to seal them off, cover/get rid of all moon dust and build permanent bases there (but as of now the priority seems to be researching the polar water-ice and using moon rocks to study what the early solar system’s geology was like)
There's probably opportunity to do some really large colliders in space, for much cheaper than on any celestial body.
But then, people are having a really hard time imagining the fucking science we could get done with a lunar-scale particle collider. That's why the merely 100km one isn't getting any money.
If gravatons are a real particle, we'd need one on on the order of earths orbit around the sun to see it. Maybe someday lol.
Or a different mechanism of detection,
Why do we need to do it around a planet? Origin of Halo confirmed
Linear collider to Proxima Centauri
I think on earth is preferential, and you'd have to build it underground anyways in order to shield it from interference.
Something something "resonance cascade."
Even underground there is tons of issues. One for example is that the ground is having tides.
As the moon passes above is the ground is moving by several cm so it has to be compensated by the collider.
At the energies involved, it's akin to a bacteria interfering with a supersonic goods train. The only bit that needs shielding is the detector systems, and that's not THAT hard to do in space. At least if you're at the point of building a space based accelerator.
