The Scarcity of Life Bearing Planets
"Great spirits have always encountered violent oppositions from mediocre
minds." - A. Einstein
    There is considerable interest in the possibility that there may be a

The fine structure constant can be calculated using the following
formula,
alpaha = kC.e^2 / hbar.c
where,

The  photon is known to have no mass
The neutrino has mass
yet the  neurtino is a particle in motion-
so behaves  wave like .

Has this equation got a name?
aG = G.m^2 / hbar.c
where,
aG = gravitaional equivalent of fine structure constant

my question is as in the title
Does HUP prevents us from knowing any geometric property
of the NUC.???
TIA

While looking at a patent recently, I came across the following simple
expression for the range (R) of an energetic electron in the atmosphere
(at sea level pressure):
R = 543*E - 106

"For each kind of particle, there is an associated antiparticle with
the same mass but opposite electromagnetic, weak, and strong charges,
as well as spin." from wiki.
Electrons and positrons can have a spin of +1/2 or -1/2, so if an

All space, energy, and matter is made up of the same thing. The best
way I can describe this same thing is electromagnetic energy or waves.
This energy or waves at different frequencies determine what is space,
energy, or matter and determines how we experience gravity and time.

Are "Strong Nuclear" really strong, or we feel they are strong , since
they are so small that we cannot reach easily , for example , if I have
a feather below a heavy metal sheet and I have job to disturb the
feather by hitting as hard as possinble on top of metal sheet so that

I always hear how, under rotation, a spin 1/2 particle doesn't return to its
origin state until the rotation angle is 4\pi. Mathematically this is no
problem for me being just some facts stemming from the 2-forld cover of the
Lorentz group, but what does this rotation mean ...

If particles with spin possess a magnetic moment, does this mean that
neutrinos have a magnetic moment?
If so, how can this be since they are electrically neutral, and
according to special relativity, a magnetic force is a manifestation of

In my quantum mechanics text book it states that if the normalisation
condition for a wave
packet Psi made of a superposition of states is
Psi*Psi=1

I just want to ask if the Standard - Model of Leptons has a theory for the
decay times of the Myon and the Tau.
What Environment Parameters (Bonding in an Atom, Temperature etc. )
influence the decay ?
