Just get it over with and start building an equatorial particle collider already.

Can we get a collider between moon an earth? I know, a lot of particles out there, but if we isolate it?

We currently can't block enough radiation to make space travel safe for humans in long term situations unless we are blessed with the calmest of space weather based on some recent news about the long term effects on the kidneys in the conditions of space travel (source, I believe the research still needs to be corroborated https://phys.org/news/2024-06-astronauts-kidneys-survive-roundtrip-mars.pdf )

We're still not at the Star Trek radiation screen level, unfortunately. So I'm not confident we can isolate this well enough. Earths magnetic field and atmosphere do a lot of work for us, and we still cannot replicate their function well enough to make it safe for humans long term. And this is a project that was put underground because it was more sensitive than humans.

Put one of them magnet floating trains on top please.

The equator express.

Free power as well. I see no downside to this.

Accidentally accelerates the whole mass of the sun in a fragile ring of superheated plasma at ridiculous speeds.

Orbital particle collider or bust

[–] [email protected] 6 points 1 year ago

That's what the asteroid belt is for!

[–] [email protected] 1 points 10 months ago

The GEO Particle Collider.

[–] [email protected] 5 points 1 year ago

Just put it in orbit! Let's commit and put a ring on this planet!

[–] [email protected] 4 points 1 year ago (1 children)

Honest question could this be feasible with a few dozen satellites positioned above the Van Allen Belts to accelerate particles, and just letting the particles raw dog the solar wind and ride around Earth's gravity well between each acceleration satellite? Cause that would be badass

[–] [email protected] 4 points 1 year ago (1 children)

No, to orbit the earth at an height of let's say 1000 km you would need a speed of around 7km/s. If you go faster, you don't follow an circular orbit. Wirh around 11km/s you would be so fast to leave the gravity well of earth. The particles in those colliders are almost moving at the speed of light. To be exact, they move only 3.1m/s slower than the speed of light, so almost 300000km/s. They would fly almost straight and would be barely influenced by the gravity well.

[–] [email protected] 2 points 1 year ago

Ok, so a huge circular tube it is then

[–] [email protected] 2 points 1 year ago

Skip that. Put it in orbit and make it double as a solar collector array and beam the extra energy back down.

Saturn is one step ahead of us

[–] [email protected] 1 points 10 months ago

Perfect! A bunch of raw materials are already there! We just need to refine them and assemble them into a particle collider.

The two first are the same?

[–] [email protected] 7 points 1 year ago

Ops, I meant the Proton Syncrotron.

[–] [email protected] 15 points 1 year ago (3 children)

It'll still be called the Future Circular Collider when it's shut down after forty years of service. You gotta commit to a scale in the proposal, like the Overwhelmingly Large Telescope.

[–] [email protected] 12 points 1 year ago (1 children)
[–] [email protected] 8 points 1 year ago

Maybe that's the real Kardashev scale...

[–] [email protected] 12 points 1 year ago

Just one more collider bro I swear just this one and we'll fix the standard model bro just one more I swear

[–] [email protected] 10 points 1 year ago (2 children)

The last time? aaaahahahaa... no. There are several phenomenon that require energy levels that only stellar objects can throw off. They'll be asking for bigger colliders even when they're dedicated space stations firing what would be equivalent to weapons of mass destruction at each other.

Unless scientists can figure everything out just by observing space, there will always be a demand for a bigger collider. Since scientists like to control variables and don't like waiting for random events that they then almost have to reverse-engineer to explain (without most all of the sensitive detectors built in to these colliders), there will always be a demand.

[–] [email protected] 6 points 1 year ago

I said 10y, but yes it will need a lot more colliders.

“We just want to smash two little planets together at 99% speed of light!”

Larger Hadron Collider

[–] [email protected] 7 points 1 year ago (1 children)

Why does a larger loop mean better results?

[–] [email protected] 12 points 1 year ago

More size = more speed and more particles colliding = more bang = more data = for example possibility for dark matter and/or heavier particles to be found.

[–] [email protected] 4 points 1 year ago

I like how it went from second to third picture. Borders? Who needs borders?

[–] [email protected] 3 points 1 year ago (2 children)

I can probably look this up but how does size effect the result in these things?

[–] [email protected] 8 points 1 year ago (2 children)

The limiting factor is the bend. The subatomic particles want to go in a straight line. A magnetic field is used to bend the beam around into a circle. The faster the particles are moving however, the more energy is needed to bend them. A larger circle has less bend. This lets you get your particles faster.

Since E^2 = M^2 C^4 + P^2 C^2 (the full form is E=MC^2 ). If you can force the particle to stop rapidly, then you can force the energy from momentum into mass. This is done by hitting 2 beams into each other. The faster the beams, the more energy is available to convert to mass.

Most of the time, this creates a lot of mundane particles. However, ever so often it creates something interesting. They rapidly decay into mundane particles, but the shower they create tells us a lot about them. The catch is that all the energy needs to be present at once. You can't use more particles, you need to make them move faster.

As for why. The more particles we have to study, the more we can figure out about the underlying rules. We have a number of theories. They all agree at lower energy levels, but disagree at higher energy levels. By knowing which is correct, we can pry deeper into the workings of reality.

Thanks! I'm personally in favor of doing things for knowledge's sake. That said, what is the stated practical benefit when some government body is writing a check?

[–] [email protected] 4 points 1 year ago

There's a story, though I'm not 100% sure on how true it was. Queen victoria did a royal visit to the new lab overseen by Michael Faraday. She asked him what use this new "electricity" was? His response was along the lines of "mam, we're not completely sure, that's why we are researching it.

As for actual uses. It could give us the theoretical key to room temperature super conductors. It could give us a foundation for exotic space drives. It could help crack new forms of fusion reaction.

Ultimately, it's a foundational block. What gets built on there is hard to predict. By comparison, GPS is not an obvious extension of relativity. However, without an understanding of relativity, GPS would basically be useless. It would drift km/day

More size = more speed and more particles colliding = more bang = more data = for example possibility for dark matter and/or heavier particles to be found.

[–] [email protected] 2 points 1 year ago

Just wait until the day somebody makes one that's a full 1 AU in radius.

[–] [email protected] 2 points 1 year ago

Honest question: why is a larger collider even needed? Just make the particles run more loops around your track.

[–] [email protected] 1 points 1 year ago

10 years? Hahahahahaha, sure
