It is my understanding of Feynman's description of anti-matter, that
it is totally consistent to say that anti-matter is nothing more than
real matter moving backward in time. In other words there is no need
to postulate a different type of matter – ordinary matter moving

According to Dr. John G. Cramer, Professor of Physics, University of
Washington, Seattle, the most accurate measurements to date for the
mass of an e-neutrino are too fantastic to believe. (What is actually
being measured is e-neutrino mass-squared).

What if an electron has a radius - how could a quantum field theory be
built from this idea?
Here's one idea.We look for something invariant:
Let's use the  idea of  (mass x length) = constant.

The Higgs particle may never be found - Stephen Hawking doubts that it
exists.
If mass isn't due to the Higgs, could it be caused by
electromagnetism?

If I have two negative electric charges, one of them with a far larger
magnitude than the other, orbiting a positive charge,this system of
charges could represent a rotating electric field vector and a
rotating magnetic field

Paul Dirac proposed that gravity was stronger in the past because G,
the gravitational constant, is getting smaller as time passes.People
who object to this idea say that the Sun would have burned up far more
fuel by now if gravity had been a lot stronger millions of years

The Paradox of Zeno
    The Paradox of Zeno is 2000 years old and its apparent ability to prove
that all motion is impossible was not resolved until the mathematical
techniques of Calculus became available, even though that technique is not

How does one explain that particles associated with a force
('force-carrier') must have integer spin?
I have read the following  in "Feynman Lectures on Gravitation." (for the
special case of a graviton):

Can the speed of radioactivity be measured, it beats the speed of light.

Are Unified Field Theories Justified?
    Modern physics seems to be searching for ways to incorporate all physical
phenomena into a single unified theory. The question that comes to mind is why?
The question arises as to the conceptual need for such an activity and whether

Could someone remind me why a meson must necessarily be a quark and an
anti-quark rather than two of one or the other?  I assume that there is
some fundamental symmetry that requires it (and I have a sneaking
suspicion that someone has already explained it to me, although I ...

If a hypothetical aether contained positive and negative electric
charges,
then a "local" electric field could exist between a proton and one of
the charges.If the aether also contained magnetic charges and the

Consider that with the logic used on the zenon paradox, you will have
to accept that you cant move at all and that you cannot get nowhere,
because if you cannot reach your target, or wherever you wanna get,
you cant even get the first half of the distance to that target,

That's GREAT!

A team of nearly 100 physicists from around the world have achieved
results verifying that the elementary particle known as the neutrino

does anybody know why large-rapidity gap events at Hera are called
diffractive events? I don't see the link between those events and
diffraction in optics. Is there any?
Thanks a lot!
