Like normal when the questions get tricky rather than dealing with them the thread is removed like the one just from main that as been locked.No, it's when they get to the point of being ridiculous.
NO we don't, nobody observes single photons making contact with the retina, that is of the imagination, stop lyingBefore you accuse people of lying you might take the trouble to check facts, it would at least be polite.
Space - space is the volume of ''empty'' distance that surrounds an observer
Distance - An isotropic unbounded quantity of N-dimensional space extending away from the observer
Length -1. A measured distance of finite bounded space between two light reflective or light emitting point sources.
2. A measurement of an objects physical dimensions of its form.
Universe - an unbounded N-dimensional space
Visual Universe - a finite observed length within a Universe
Matter - Solidity or substance that occupies space
Energy - A group category for various types of power.
Power - The ability to do work : the generation of electrical energy at an atomic level
Objects - matter existing in bonded clusters.
mass -The rest force measurement of a body at rest relative to an inertial accelerating reference frame.
Motion - the continuous displacement of matter in space
Dimensions- The measurement of a physical object : the measurement of a volume of space
Gravity - the property of matter that has directly proportionate attractive ability.
Force - 1. The exchange of energy to create work
2. The inertia existing between two bodies at relative rest mass to each other.
Second of all, look up "binding energy." When a photon is absorbed by an atom, its energy becomes mass, plain and simple.
Third of all, mass/energy "equivalence" means exactly that. Mass can be converted to energy, and energy can be converted to mass. They are the same thing in different states.
Did you know that when matter and antimatter annihilate each other, you get energy? Sounds to me like "matter" is probably made of energy ...
So stop arguing with me for saying the same damned thing.
Electrons don't flow. They oscillate. It's the energy that travels. A good mechanical analogy is dominoes. Stand them up in a row next to each other. Push the first one over, and they all fall down one by one, but it is the energy that travels from domino to domino. No dominoes actually travel from one end of the line to the other. They stay in a row, in order, as the energy travels from one to the next. Another example would be one of those desktop kinetic sculptures with a row of suspended stainless steel balls, bounce one at the end, and the two end balls bounce while the ones in the middle stay in place.
A photon is a carrier of the electromagnetic force. When a photon is absorbed, its electric and magnetic components tell the particle that absorbed it to oscillate faster. There is no "flow" of electrons.
Energy is equivalent to mass times the speed of light squared. When a photon is absorbed, it stops travelling at the speed of light and contributes a tiny amount of mass to the system that absorbed it.
But... before I depart, and on the basis that this forum has a 'Cambridge University' symbol attached to top of page... so I am expecting a 'definitive' answer on this...This forum is hosted by TNS Cambridge University, but the forum is open to anyone and my understanding is that the University doesn't have a team of experts standing by to give definitive answers.
