Light speeds unimpeded at c (~299,792,458 m/s)
Lossless information transfer via light
Complete blockage of light
Inaccessibility of light-encoded information
Sound reigns supreme as c (~343 m/s)
A medium that negates vacuum forces reliance on alternative information carriers (sound, mechanical waves) and challenges light-based tech
So the event horizon, cross that and lig htspeed is demoted to the speed of sound, thus even the plank length would variate for information takes longer to traverseSound waves (limited by the speed of sound).
Other mechanical waves (dependent on medium)
In a vacuum, light propagates unimpeded at its maximum velocity. This allows for lossless transmission of information encoded in light signals. However, in a medium that completely obstructs the passage of light, communication and information exchange would necessitate reliance on alternative carriers not based on electromagnetic radiation.
Contemporary communication technologies are heavily reliant on light-based transmission. The advent of a medium that completely blocks light would necessitate a radical shift in technological paradigms. New technologies would need to be developed.
Even in the most empty regions of space, quantum field theory predicts the constant creation and annihilation of virtual particles. These fluctuations mean that a true vacuum is never truly empty.
In the vast spaces between stars and galaxies, there exists a very diffuse interstellar medium consisting of gas, dust, and cosmic rays. While extremely dilute, it's not a perfect vacuum.
Creating a perfect vacuum in a laboratory is impossible with current technology. While we can achieve extremely low pressures, some residual particles and gas molecules always remain.
The Pauli Exclusion Principle states that no two fermions (a type of elementary particle) can occupy the same quantum state simultaneously. This principle limits how closely particles can be packed together, preventing the creation of a truly continuous, matter-filled space.
The strong and weak nuclear forces govern the interactions of particles within atomic nuclei. These forces prevent matter from collapsing into an infinitely dense state.
A completely matter-filled space would likely require new physics beyond our current understanding. We don't yet know how matter would behave under such extreme conditions.
Even though perfect vacuums and anti-vacuums are unattainable in practice, they serve as valuable theoretical constructs:
A black hole with its hawking radiation, is like the "vaccuum" of space. Never constant. A black hole demotes lightspeed into soundspeed into 1The negation of a vacuum presents intriguing questions regarding the nature of information transfer. While alternatives exist, the technological hurdles would be considerable. Further exploration could yield valuable insights into communication and information propagation, with added insight into applicable interdomain data transfer: As one domain can have multiple child nodes, so there are cognate dimentions that follow same pattern behaviour as biology, linguistics, and
