Rather than alien spacecraft, could some UFOs actually be living beings which normally inhabit the cosmic void?
"Zeroid" is the generic term applied to bioforms which may populate the recesses of free space. This domain is characterized by virtually zero temperature and zero atmospheric pressure.
While biologists might contend space is unsuitable for biogenesis, Russian astrophysicist Dr. V.l. Goldanskii argued that appreciable quantities of prebiotic material should be able to accumulate in the regions surrounding nebulae, or titanic gas clouds.
With the protracted passage of time, such matter could ultimately evolve into some form of life, suited to the brutal confines of space. Already dozens of organic compounds have been identified in space, including formaldehyde, prussic acid, and cellulose. In short, there is an abundance of basic building blocks out there to allow for the evolution of zeroids.
Considering that our island universe is approximately 13.7 billion years old, it is conceivable that zeroids represent the earliest life forms in the cosmic backdrop, perhaps even existing for nearly that entire time!
With such an elongated span of time at their disposal, zeroids could easily have trod many different evolutionary paths: They may range in dimensionality from the microscopic to the macroscopic.
Morphologies may vary from the utterly simple to the extraordinarily complex. They may live singly or in vast colonies. It should, of course, be stressed that humanoid forms are not to be expected. But, intelligence might be a developed feature.
For sustenance, zeroids' primary bill of fare might well be intergalactic dust and gas. Also not to be overlooked is the distinct possibility that larger zeroidal entities might possibly feast upon smaller ones.
Zeroids may have migrated to all sectors of space -- both within and without galaxies. Endowed with both mobility and intelligence, it is conceivable that some may have actually penetrated our zone of existence and been seen as UFOs!
Atmospheric friction might parboil some zeroids to cinders, and our planet's gases and temperature might prove lethal to still others.
Yet, some may have evolved a protective shield -- either physical or electromagnetic in nature -- that has enabled them to survive entry into our domain. These would be the living UFOs!
Actually, two UFO cases appear to support this intriguing concept. In 1976, in the Cluj-Napoca region of Romania, there materialized what appeared to be a living sphere of light exhibiting decidedly-animate behavior. Photographs taken of the entity passed all tests for legitimacy.
And, in British Columbia in 1978, researcher Dorothy Wilkinson snapped the first of many shots of bizarre string-like forms of light that resembled space worms!
So, considering the vastness of both space and time, it is certainly within the realm of feasibility that at least some UFOs may actually be living space creatures!
