Even as a Fourth Rank powerhouse, Su Yu couldn't sense their existence.
However, they possessed gravity and could be collected by the Manifestation Space.
"Is this... dark matter or dark energy?"
Su Yu pondered for a moment, thinking to himself.
The so-called dark matter refers to the vast amounts of invisible gravitational sources calculated by scientists to exist in the universe.
They do not emit light, only gravity, maintaining the stability of star systems and even the entire universe.
These things are collectively known as dark matter and dark energy.
Before his traversal, Su Yu had some understanding of dark matter and dark energy.
At that time, these things were still unsolved mysteries to him.
Of course, after his traversal, they were no longer unsolved mysteries.
Especially after encountering the Mechanical God, Su Yu acquired a vast amount of knowledge and learned the realities about dark matter and dark energy.
