It's to my understanding that the Large Hadron Collider is so 'large' due to the fact E=MC^2 and that when the accelerated particles approach the speed of light their mass increases logarithmic to a near infinite mass, meaning the magnetic force applied to the particle, to stop it from touching the sides of the chamber and slowing down, has to be equal to the particles new weight. Taking this to be correct, if we were to build a Hadron Collider/particle accelerator in outer space where the effects of gravity are almost negligible, would it have to be so large? My reasoning is that it would need less force to keep the particles from touching the sides as there will be less of a gravitational force attracting it to the side. I can see obviously that with my ‘Small Space Hadron Collider’ it would take longer for the particles to reach 99.999% the speed of light like they do in the LHC due to the smaller magnets and less of a Horizontal component accelerating them around but i believe building one in space would also be more efficient as LHC uses a lot of energy to become as close as we can to absolute zero as we can, however this would be a much easier task in space as for one we are in space which is already really really cold (2.6 kelvin or so) and two the SSHC would be smaller and not as much would need cooling. The two major flaws with my idea, which i can see, is first of all getting it into space, which is of course expensive and logistically challenging and secondly powering the thing, solar panels are great but I’m doubting their ability to run the magnets long enough to approach C, even with batteries, capacitors and fuel cells a lot of electrical engineering would be required to supply sufficient power for long enough, in my opinion. So why do it? My main reason is the production of antimatter, the more we can make and test the closer we get to antimatter rockets and the future of space propulsion, the SSHC could be the very first space fuel station. it can also answer a lot of fundamental questions scientist have had about not only approaching the speed of light but how these new wondrous particle we discover at the LHC behave in space. I would love to hear you thoughts on this, especially any other ideas on uses, any other major flaws i am not seeing and your general opinion.
