| Gravitation of subatomic particles | 30 Jun 2004 16:51 GMT | 3 |
Some people seem to think that Gravitation only
happens between large groups of particles, and
not between individual particles. Have any
experiments actually measured gravitational

| decay of radioactive isotopes | 30 Jun 2004 00:22 GMT | 1 |
Is it possible for a certain radioactive isotope to decay into
different elements? For example, can potassium-40 (K-40) decay to
argon-40 (Ar-40), as well as to K-39 or K-41? Is this or any similar
example possible?

| A new symmetry in nature | 25 Jun 2004 15:00 GMT | 7 |
If I take a large mass such as the sun and change its negative
electric charges (half the total number of charges) into positive
charges, so all electric charges are positive, and I transform the
electric force so that like charges attract, the charges would be

i read on one of the messages that the mere fact that the sun emmits
light proves that photons dont have mass.....why ? ¿ because if not
the photons will fall back into suns gravitiy?
