The definition of ‘virtual’ in the dictionary refers to a presumed existence or subject that is treated as if it does not exist in reality. However, in contemporary usage, ‘virtual’ describes something that cannot be physically sensed by human beings. For instance, ‘virtual currency’ exists in the form of bits, as it cannot be perceived sensibly. Just because you can’t feel it doesn’t mean it doesn’t exist. In fact, human senses cannot detect the smallest unit of atoms that compose all things, yet that does not negate their existence. If something that does not exist but can exist as a hypothesis is called ‘virtual,’ then it exists in reality as a concept as soon as it is assumed! When something is hypothesized, the entity that is assumed originally did not exist, and the subject who made the assumption had not existed from the beginning, thus proving its existence by expressing the will of that assumption. Therefore, distinguishing between virtual and real holds no ontological signifi...
In September 1999, NASA’s unmanned Mars climate probe “MCO” exploded in Mars’ orbit. Manufacturer Lockheed Martin set up the data unit as a “yard,” but NASA mistook it as a “meter.” The MCO entered the atmosphere of Mars 100 km below the original orbit and exploded in friction. Communication error had blown away $ 125 million. With this opportunity, NASA decided that the units used in space development were “meters”. A slip of the tongue in business doesn’t end just a mistake accidentally. It must undoubtedly damage the “cash flow”. - Joseph’s “just my thoughts”
