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.
Well spoken people never say "this point in time." We say "now" or "at present" or "currently" and informally "nowadays."
A pendulum moves at its fastest when it is at the bottom of its swing, also known as the equilibrium position. At this point, all the potential energy has been converted to kinetic energy, resulting in the highest speed of the pendulum.
It is a potential source of energy that is readily available where there are people who need it.
A tangent line touches the circumference of a circle exactly at one point.
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.
Tangent
point of intersection.
Definition: a tangent is a line that intersects a circle at exactly one point, the point of intersection is the point of contact or the point of tangency. a tangent is a line that intersects a circle at exactly one point, the point of intersection is the (point of contact) or the **point of tangency**.
same risk as anything nowadays, everything seems to be dangerous at some point
No, the comma does not always go after "nowadays" at the beginning of a sentence. Whether a comma is needed depends on the context and the rest of the sentence. If "nowadays" is being used to introduce a contrast or emphasize a point, a comma may be used. However, if "nowadays" is used as part of the subject or the main idea of the sentence, a comma may not be necessary.
EXACTLY : precisely, to the point
To intersect.
