Well, the simple answer is we didn't. The more complicated answer involves, if you want to believe these kinds of things, extraterrestrial technology. It's hard to provide evidence on something your government doesn't, at all costs, regard at true for some strange reason. But evidence for this claim ofnon-human technologies "leaking" into the corporate sector can be found and many places if you know where to look. For example, one company which receives a great deal of money from both the U.S. military and NASA is the Analex company. And I don't know if they changed this on their site for obvious reasons or not, but much of the company's doings are in "retro-engineering". One must ask themselves, what would a company in the world's technological super power, let along one funded by NASA, ever find themselves with the need to retro-engineer technology, presumably being the foremost in technology?
It wouldn't be worth mentioning if it was a singular case, but...
Sadly, you can find companies like this all over, typically concerning military, aeronautics, or advanced medicine and computing, ect... It's great that the technology is springing up, its sad that few people are bringing the technology's origin to public attention however. Chances are, as with all technology, we just *need* to misuse it for a little while first.
The point of impact or cataclysmic event.
The term ground zero describes the point on the Earth's surface closest to a detonation. In the case of an explosion above the ground, ground zero refers to the point on the ground directly below the detonation. The origins of the term ground zero began with the Manhattan Project and the bombing of Japan.
Mayans developed zero as a placeholder around A.D. 350 and used it to denote a placeholder in their elaborate calendar systems. But Mayans never used zero in equations.

Henri Becquerel discovered in 1896 the natural radioactivity.
zero point energy generators exist in the modern world only in theory. Any you find that have been made are scams. Scientifically, the zero point energy generator is an ideal that cannot yet be reached.
The kinetic energy of the car becomes zero when the car halts. If it halts on top of a hill, the energy changes to potential energy.
Zero point energy, or the energy of the vaccum, remains speculative. No one is currently using it for anything, and no one knows how to access it, if such a thing indeed will ever be possible.
Zero point energy is the lowest possible energy state that a quantum mechanical physical system may have, even at absolute zero temperature. Dark energy, on the other hand, is a hypothetical form of energy that is believed to be responsible for the accelerating expansion of the universe. They are distinct concepts in physics.
There are no references online to this exact expression, but perhaps it refers to Zero Point Energy which is the energy still present even when matter has been cooled to absolute zero. This energy is locked up within the atom in the form of particle spin and electron orbit momentum as well as more exotic quantum effects. There is speculation that zero point energy and a corresponding zero point field is part of the most fundamental properties of matter and of the universe as a whole.
Because absolute zero (or 0k) is the point at which EVERYTHING freezes. More specifically, absolute zero is defined to be the point where there is no energy. You can't have less than no energy.

The value of ΔG at the melting point is zero for a substance undergoing a phase transition because it is the point of equilibrium where the free energy of the solid phase equals the free energy of the liquid phase.
No. From what I understand, the Uncertainty Principle won't allow this - so even at absolute zero (a temperature that can't really be achieved 100%), there will still be some vibrational energy left.
The measurement scale that has an absolute zero point is the Kelvin scale for temperature. This means that zero Kelvin represents a complete absence of thermal energy.
Space-energy, also known as zero-point energy is the lowest possible energy that a quantum mechanical physical system may have and is the energy of the ground state, which is non-zero.
