Anilkumar Posted November 24, 2012 Share Posted November 24, 2012 Hello Michel123456, hello everybody, We have to see it like this. This sounds a bit offbeat but it gives the necessary insight. I am not being speculative here. I am just trying to give the theoretical interpretation of the mathematics. The nature is governed by this law, [subject to correction by the knowledgeable]; "Any particle with mass cannot move at the speed of Light. And any particle without mass moves at the speed of Light." Here Mass & c are constraints on matter. Matter has either Mass or c. If Matter has mass it has no c. If it has c, it has no mass. Accordingly, Momentum has two definitions. It is either mass times its velocity or it is Energy conveyance [light propagation] at c. There are dual definitions because Matter is dual in nature. Its manifestations either have mass or is pure mass-less energy at c. I.E. Matter is either a mass moving at a velocity less than c or a mass-less manifestation [named as Photon] at c. Therefore, accordingly. Momentum of Matter is either a mass moving at a velocity less than c times it's velocity or a mass-less manifestation moving per c. To put it simply, Matter either has mass or c and accordingly Momentum is, either m*v or E/c. Or, Matter/Energy either has mass or c and accordingly Momentum is, either m*v or E/c. Let me put it in another way, 'If you transform a matter particle with mass into a mass-less one it starts moving at c and vice versa'. So, Matter either has mass or c and accordingly Momentum is, either m*v or E/c. It is the same thing. A massive particle moving at less than c or a mass-less particle at c. Both have Momentum. They don't lose that Momentum when they are transformed into one another. That Momentum does not vanish just because Matter gets transformed into a different manifestation. If we are concerned about the units, even there too there is nothing much complex to understand. And, This thread has become interesting, with the why? and other things. Let us see if the OP gets answers to his why's & how's. I liked Steven Weinberg thoughts & Juanrga's 'the descriptive science is just a part of science. Answering "why" is another part of science'. I think man will be able to answer everything including all the why's in the very near future. Have a nice day. Link to comment Share on other sites More sharing options...
