As far as our current understanding of the laws of physics and the capabilities of the universe, there is no evidence to suggest the existence of infinite strength or power. The concept of infinity often resides in the realm of abstract mathematics rather than the physical world.
In the realm of physics, there are fundamental limits and constraints that govern the behavior and capabilities of objects and systems. For example, in the theory of general relativity, which describes gravity, there is a limit to the strength of gravitational forces based on the mass and distance between objects.
Similarly, in quantum mechanics, there are limits to the amount of energy that can be contained within a given system. The Heisenberg uncertainty principle sets bounds on the precision with which certain pairs of physical properties, such as position and momentum, can be known simultaneously.
While individuals or characters with superhuman or seemingly limitless powers are often depicted in works of fiction, such as superheroes, these portrayals typically go beyond the boundaries of what is currently understood to be possible in the natural world.
It's important to note that our understanding of the universe is constantly evolving, and future scientific discoveries may uncover phenomena or principles that challenge our current knowledge. However, until such evidence is found, the existence of infinite strength or power remains speculative at best.
