Colliders Are Like Real Experiments

We have created matter just from colliding light. In order to do it, we need higher energy beams of light than even x rays can provide. These are like real experiments you've done in colliders. The issue is that while lazers are really good at making coherent sources of monochromatic light, they're not actually grated making very high energy photons. Even x ray lazers are hard to do. We need things like well above x rays, well above gamma rays, like super high energy photon.
