E=mc^2, Inertia, Pair Production, why? |
In 1905, Einstein wrote a paper called "Does the Inertia
of a Body Depend on Its Energy Content?". The idea is
summarized as:
1. the old definition of work (W=Fd), combined with
2. the new fact, nothing can go faster than the speed
of light expressed by F=(ma)/[(1-v2/c2)^3/2]
3. the work goes into making the body heavier. Therefore
4. work adds to the inertia of a body and by implication
inertia has energy and to make it concrete
5. the relationship between energy and inertia is
E=mc^2
6. but remember... nobody really knows what inertia
is - or why objects have it in the first place
This was in 1905.
Particle accelerators began operating decades later.
From E=mc^2, M=E/c^2. This means if you can give enough
energy (photons + electric field for example). You
can literally create matter out of pure energy.
Isn't it odd how Einstein formula could have predicted
it. This shows Einstein must be a super genius and one
of a kind.
But what does inertia.. which has a lot to do with the
equation of E=W+mc^2 (where work is zero) relate to
pair production and actual precipitations of particles??
Albert argues that as you give an object more and more
energy, instead of going faster and faster it gets
heavier and heavier. So if you gave a rocket
1 x 10^1000 foot pounds of thrust, it would stil be
going less than the speed of light. So Einstein
thought that if work goes into giving the body more
inertia.. then inertia must contain energy. What
Albert is saying is that even if work = zero. If you
don't put in any work at all, then the electron still
has an energy equal to e=mc^2
Decades later, Particle Accelerators have been
precipitating particles out of pure energy. My
question is.. What is Inertia relationship to the
energy inherent in matter?? How could Einstein equation
produced in 1905 foresee all of the accelerator
results?
Einstein is such a genius I can't understand how
some of you plan to outsmart him and reworking all
his equations.
