Of anti-protons! While it's not as visually cool as what Saturn has going for it, this is still an important development, even if we can't technically "see" the ring with our primitive Earthling eyes.

According to New Scientist, this anti-proton ring joins the previously discovered positron cloud that's also circling the Earth like an invisible shield. Ironically, the anti-protons are 2,000 times more massive than their positron counterparts, but were discovered second. Both are trapped in a donut-like ring called the Van Allen radiation belt that's held in place by the planet's magnetic field.

In the distant future, a spacecraft designed to use anti-protons (or other types of antimatter) as a fuel source could tap into this ring to top off its tanks and head out into the void, said Alessandro Bruno, a member of the University of Rome Tor Vergata team that confirmed the anti-proton area's existence. I'm really looking forward to that not happening in my lifetime!

Wow, being surrounded by all of these humourless, pussy-whipped virgins is starting to make me sick.

Check out my band!

makes me laugh, we discover something new about the planet earth and the first thing to be mentioned is using it as a fuel source. now maybe well be able to leave earth after weve raped all of its resources and spread our depletion out into space!!

How do the anti-protons not collide with spacecraft and orbital junk?


They do, but our ozone layer and clouds and everything don't let us see the explosions normally. When we see fireworks, the rocket is just temporarily destroying the atmosphere, so we see the pretty antimatter explosions high above our heads

because they are elementary particles, a fraction of the size of an atom

Thats like asking why UV light doesn't collide with us.

Elementary particles still collide with matter. I assume that they are evenly distributed throughout this ring and in constant motion around the earth, so if a spacecraft passes through this ring then a collision is likely.
Is it just probability that prevents a reaction from occuring? Are they repelled by the gravity of matter? Or by the weak nuclear force? I apologise for being an idiot, but I just don't get it.

But UV light does collide with us.

I'm confused now.

They're both collisions, but on the scale that they happen and have effects they don't register to the unaided human senses.

Except for sunburn, and maybe there would be similar effects for matter passing repeatedly through the proton belt.

the spacecraft wouldn't consists of any positrons so it wouldn't annihilate. it's the same as saying UV colliding with us because waves can act as particles but the effects of them being particles when they collide with us are negligible!
