"Appetizer? Main course?"
When those two words slipped out of Xu Yun's mouth,
Old Fa, Stokes, and the other professors all felt a strange sensation well up inside them.
A measurement of the speed of light, enough to shake the scientific world at present, was nothing but an appetizer in Xu Yun's eyes?
Are you kidding me?!
Don't be fooled by how fancy "speed of light" sounds.
In reality, it's a fundamental property—just a data point among physics 'basics.'
First, it represents the upper limit of light's motion.
Or, to put it another way, the upper limit for the transmission of information and energy.
Which means that events occurring in different regions of the universe won't reach Earth—or any planet with life—instantaneously, and living beings won't be drowned in a flood of information.
In this way,
the macroscopic world can function properly—from a modern perspective, you could say it enables the normal course of evolutionary life.
