    • Before we delve more deeply into the details of particular kinds of collisions, what do you think are the limitations of particle accelerators/colliders in achieving even higher particle energies? Explain your answers.

    • Reach higher energies. I think building a collider that achieves even higher energies is challenging from a technological point of view.

    • There is a speed limit cap for the particles. We know that C is the fastest speed we can have, and we can say that we can achieve higher particle energy with higher speed, but there will be a point where that speed will capped out. We need to find another way to increase particle energy other than speed.

    • cannot figure out a way to isolate Planck size particles. or more particulars about Higgs field.

    • yes

    • The amount of energy required to continue to accelerate particles to incrementally higher speeds approaches infinity asymptotically as their speed approaches the speed of light.

    • One large problem is the safe management of the stored energy while operating the machine

    • The B-field energy required for centripetal acceleration of particles is more so a limiting factor than the speed of light (no energy limit due to asymptotic nature).

    • C is the maximum speed any particle can achieve as at now and this presents a liability to discovering new physics beyond bombarding protons at c. Maybe accelerating the particles beyond c may result into something more complex and new, who knows!

    • “what do you think are the limitations of particle accelerators/colliders in achieving even higher particle energies” mainly the issue is the power of the magnetic field that keeps particles in curvature. As far as I know at the moment the biggest “jump” in technology was to switch to magnets operating as superconductors. Since there is no great way to improve that part of hardware the only way to have higher energy which means higher speed (closer to ‘c’) is to make the whole accelerator bigger.

    • There limit is the energy composing angelic entities.

    • Collider energy is directly proportional to its size, therefore collider size is the limiting factor. For exciting developments we would need to build it in space.

    • You are almost correct. Due to the fact that Dark Energy would require asymptotical amounts of energy, the collider would have to be larger than the universe.

    • I think if we find Higgs Boson, it would strongly support the supersymmetric Standard Model, which in turn supports the notion that string theory is indeed the right approach to nature.

    • Reaching higher energies

    • To the best of my understanding of how particle accelerators work, I think there are two reasons that pose potential challenges when we try reaching to even higher energies,

      1. Very strong magnetic fields are used to focus the energetic particles to make sure that the collisions happen at higher energies. As the particles gain more and more energy, the strength of the magnetic fields used to keep the particles in focus must increase too. At very high energies, the magnetic fields needed to focus the particles rises which forms a challenge.

      2. For Linear accelerators, the length of the accelerators must be large to energize the particles to high energies. This forms another potential challenge for high energy particle accelerators.

      In general, despite the design of the particle accelerators, as we reach out to higher and higher energies, the size of the accelerators go up which in turn cause the cost to go up.

    • Higher energy means higher costs to build and maintain accelerators which will make it difficult to get funding

    • very interesting and enlightening for a layman.

    • Hello Ladies and Gentlemen,

      In reading of this, we see funding limits the tools built for experiments.

      Also, when listening to the production manager for the JWST, he cites the need for space facilities to work from. This may be a wishlist item for scientist in collider work also.
