When he saw the praise Xu Yun wrote about him, Newton couldn't help but let a proud smile curl up at the corner of his lips.
But soon after,
that smile was quickly replaced by seriousness.
Because he then saw Xu Yun's reply related to his own bucket experiment.
The bucket experiment.
This was a cleverly designed combination experiment Newton came up with three years ago (in this timeline), and through it, he established what he considered to be an unbreakable concept of absolute space and time.
Newton was even proud enough to think,
that the value of this worldview concept might even surpass the law of universal gravitation, becoming one of the theoretical cornerstones supporting this world.
But in a subsequent experiment,
Newton suddenly discovered something that delivered a direct shock to his understanding.
As the famous inventor of the Newtonian reflecting telescope, Newton was also experienced in making mirrors, basically a standard DIY enthusiast.
