Final answer:
Cyberspace is distinguished from physical space by its lack of tangible dimensions and freedom from physical constraints, enabling virtual interactions like virtual reality without material costs. It operates under different rules, where information travels freely through electromagnetic waves, not bound by physical mediums.
Step-by-step explanation:
According to Dyson, what distinguishes cyberspace from physical space is fundamentally rooted in the nature and concepts of interaction and existence within each realm. Cyberspace, as opposed to physical space, does not have tangible dimensions and does not conform to traditional physical constraints that govern our everyday lives.
In cyberspace, humans can engage in activities such as virtual reality, which allows for virtual travel and exploration without the material costs and limitations of physical travel. This notion aligns with the idea of engaging with space-time in a way that is divorced from the physical scale, as we do when experiencing interstellar travel through a movie.
In cyberspace, electromagnetic waves, comprising the transmission of information, need not physical mediums like air or water to travel - much unlike sound or water waves, which require a medium.
The interaction renders cyberspace as a realm governed by different rules, bridging philosophical and neurological constructs without adhering to the physical laws, such as those found in the realm of physics, that dictate speed limits or the conservation of energy.
