-Is Mr. Lindley right? He concludes: "We are already at the point where experiments are becoming impossible for technological reasons and unthinkable for social and political reasons. An accelerator bigger than the supercollider would be a vast technical challenge. . . . Experiments to test fundamental physics are at the point of impossibility."​ Physicists, he says, seem to be returning to the days of the ancient Greeks, who did physics "by means of thought alone."​ Maybe he doesn'​t know about the Livingston curve. Mr. Lindley, I'm sure, would hate the Livingston curve. It's one of those mathematical curiosities that are probably meaningless. In the 1950'​s,​ a physicist named Stanley Livingston drew a line on a graph that plotted the energy available in laboratories from the time of J. J. Thomson (circa 1897) to his own era, then extended it into the future. He found a logarithmic relationship:​ the energy increased by roughly a factor of 10 every 10 years. The Livingston curve has accurately predicted accelerator energies in the 1960'​s,​ 70's, 80's and 90's. Extrapolated to the future, it predicts that we'll have what is called Planck-scale energy in the lab by the year 2150. A Planck-scale accelerator would be powerful enough to prove one of the most popular unified theories, superstring theory.

 +<​blockquote>​A particle collider is essentially a large microscope. It doesn’t use light, it uses fast particles, and it doesn’t probe a target plate, it probes other particles, but the idea is the same: It lets us look at matter very closely. A larger collider would let us look closer than we have so far, and that’s the most obvious way to learn more about the structure of matter.<​cite>​https://​backreaction.blogspot.de/​2018/​03/​the-multiworse-is-coming.htmly</​cite></​blockquote>​
  
---Common Question 2#+<​blockquote> 
 +Richard P. Feynman once said that doing elementary particle physics is a lot like banging two fine Swiss watches against each other and trying to figure out their workings by examining the debris. That was the challenge.
