Due to the vastness of the gap in energy levels, this hypothesis is called the "Big Desert." The vast majority of civilizations die of thirst midway, unable to see the next step.
Thinking of this, Zhang Yuan sighed to himself, "The Universe is so vast, I wonder if there are any super civilizations willing to undertake god-like projects such as the Galactic Ring Accelerator..."
However, on second thoughts, colliders are not necessarily the only way.
As early as the 20th century, scientists had proposed that to continue exploring nature, one must rely on another method, instead of brutishly probing with proton colliders.
For instance, cryophysics might just yield an unheard-of new particle when solving the conditions at absolute zero.
Unfortunately, to date, countless geniuses, in their dedicated work, still have not found a new breakthrough.
