One of the problems, as I mentioned earlier, with measuring the amount of absorbing gas along our line of sight to a star, is that measurements of the 21cm line emission are made using a very wide beam, hence low spatial resolution. So it is not known whether there is any fine structure in the ISM o ...

Conservation of energy
In physics, the law of conservation of energy states that the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can be neither created nor be destroyed, but it transforms from one form to another, for instance chemical energy can be converted to kinetic energy in the explosion of a stick of dynamite.A consequence of the law of conservation of energy is that a perpetual motion machine of the first kind cannot exist. That is to say, no system without an external energy supply can deliver an unlimited amount of energy to its surroundings.
