The last section on getting to the Planck energy is amusing.

Future Colliders for Particle Physics - "Big and Small"

(Submitted on 9 Jan 2018)

     Discoveries at high-energy particle colliders have established the 
standard model of particle physics. Technological innovation has helped 
to increase the collider energy at a much faster pace than the 
corresponding costs. New concepts will allow reaching ever higher 
luminosities and energies throughout the coming century. Cost-effective 
strategies for the collider implementation include staging. For example, 
a future circular collider could first provide electron-positron 
collisions, then hadron collisions (proton-proton and heavy-ion), and 
finally the collision of muons. Cooling-free muon colliders, realizable 
in a number of ways, promise an attractive and energy-efficient path 
towards lepton collisions at tens of TeV. While plasma accelerators and 
dielectric accelerators offer unprecedented gradients, the construction 
of a high-energy collider based on these new technologies still calls 
for significant improvements in cost and performance. Pushing the 
accelerating gradients or bending fields ever further, the breakdown of 
the QED vacuum may set an ultimate limit to electromagnetic 
acceleration. Finally, some ideas are sketched for reaching, or 
exceeding, the Planck energy.
