Nothing comes from nothing, therefore god exists?
What is energy, where does it come from?
How does a nuclear reaction stop?
Thank you for your time.

In physics and other sciences, energy (from the Greekenergos, "active, working") is a scalar physical quantitykinetic, potential, thermal, electromagnetic, chemical, nuclear, and mass have been defined to explain all known natural phenomena.
Energy is converted from one form to another, but it is never created or destroyed. This principle, the conservation of energy, was first postulated in the early 19th century, and applies to any isolated system. According to Noether's theorem, the conservation of energy is a consequence of the fact that the laws of physics do not change over time.
Although the total energy of a system does not change with time, its value may depend on the frame of reference. For example, a passenger in a moving airplane has zero kinetic energy relative to the airplane, but nonzero kinetic energy relative to the earth. that is a property of objects and systems which is conserved by nature. Several different forms, such as ενεργός,
zaa, thank you for spamming. I can search wikipedia, too. wikipedia only says the energy is something that is measurable. are you saying that energy is a concept, like other characteristics such as color, firmness, fluidity, etc...
i am not asking what energy is defined as, within the limits of our language. i want to know the essence of energy. am i illogical in asking what energy is, that it only can be defined in relation to a tangible 'thing'. Is energy intangible?
Energy; the equivalent of or the capacity for doing work.
The best way to keep a secret:- Tell everyone not to tell anyone.
a popular encyclopedia must contain no substantial concepts, so that the layman may understand it. For nonscientific purposes, the widely accepted "ability to do work" definition of energy is sufficient. I doubt that energy is an intangible characteristic, which is what the encyclopedia defines energy as....
e=mc^2
btw you cant calculate the exact moment the nuclear reaction stop
There are different types of energy.
Active energy; this includes wave power, wind etc.
Inactive or dead energy; coal ,oil, wood etc. This needs a catalyst to release it.
