[net.misc] Fifth Force

browning@ttidcb.UUCP (George Browning) (01/15/86)

        There was a recent article in the Los Angeles Times which said
a  fifth  force  had been discovered.  It is called hypercharge and is
about 100 times weaker than gravity.  It changes the answer of the old
question of whether a feather or a iron ball will hit first if dropped
in a vacuum; the feather hits first as iron has a higher  hypercharge.
I  have been unable to find any other references to this new force and
would be interested in reading anything else available on  it.  Is  it
for real?

	  :-) This should send the Unification fiends
	  back to the drawing board! BTW I saw a report
	  on the same thing in the NY Times.

This fifth force has NOT been "discovered".  Its existence has been SUGGESTED,
based on the reanalysis of some old experiments.  I expect that there are
at least a few grad students out there rushing to throw together experiments
to test this.  We should hear soon.

This talk of "hypercharge" is strange to many including me.  Apparently
hypercharge is equal to baryon number for ordinary matter.  So forget
hypercharge and talk about baryon number.

Finally, this publicity IS about something real, premature perhaps, but
not quackery.  The paper they are talking about is "Reanalysis of the
Eotvos Experiment" by Fischbach, et. al. in Physical Review Letters,
January 6, 1986.

I would like to know how the original Eotvos experiment was done.  I have
the paper, but it's in German.  Would anyone care to look it up and report
back to us?

Could someone post a reading list on Superstring Theory?  I'll wade through
technical journals but I'd rather have informative popular literature (assuming
that isn't a contradiction in terms.)

Oh, and by the way; Hypercharge?

?????

Does anyone have any more information on this?

        Yes, the newspapers jumped the gun a little bit, and
misrepresented the research as well. Someone has performed a
reanalysis of certain minor anomolies in some old experiments to
*suggest* that there *might* be a fifth force. Another author has
since asserted that the reanalysis is faulty and there is no basis for
postulating a fifth force.

	The original paper can be found in Physical Review Letters (I don't
know which issue, but very recently I would assume).  It was inspired by
recent anomalies in data from accelerator labs.  The authors, principally
Ephraim Fischbach, then went back to look at the data from a famous 1922
torsion experiment by Roland von Eotvos.  The force is hypothesized to act
on particles no more than 600 feet apart.

	The theory is certainly "for real", and the paper was actually publ-
ished, but, as Harvard's Sheldon Glashow says, "The work suggests an inter-
esting direction, but by no means should be taken as a real discovery."

1) Look in last week's Newsweek or Time.  Or "the newspapers", if you
can find the article.  Then you'll at least have the people's names.

2) If hypercharge is really important to you (your neutron accelerator
functions, or your car won't go into the garage :-) then telegram the
researcher and exchange results.

3) Wait 6-12 months for other publications with longer lead time to
pick up the story and do a citation or author search at your library.
(It's easy..just like using a big index)

4) Come back to the net and let us know the net helped cause yet
another breakthrough :-)
