Anti-Gravity?
|
|||
|
|
|
|||
|
|
Japanese scientist's findings not expected to survive further
|
|||
|
|
investigation. Japanese scientists have reported that small
|
|||
|
|
gyroscopes lose weight when spun under certain conditions,
|
|||
|
|
apparently in defiance of gravity. If proved correct, the finding
|
|||
|
|
would mark a stunning scientific advance, but experts said they
|
|||
|
|
doubted that it would survive intense scrutiny.
|
|||
|
|
|
|||
|
|
A systematic way to negate gravitation, the attraction among
|
|||
|
|
all masses and particles of matter in the universe, has eluded
|
|||
|
|
scientists since the principles of the force were first elucidated
|
|||
|
|
by Isaac Newton in the 17th century.
|
|||
|
|
|
|||
|
|
The anti-gravity work is reported in the Dec. 18 issue of
|
|||
|
|
`Physical Review Letters,' which is regarded by experts as one of
|
|||
|
|
the world's leading journals of physics and allied fields. Its
|
|||
|
|
articles are rigorously reviewed by other scientists before being
|
|||
|
|
accepted for publication, and it rejects far more than it accepts.
|
|||
|
|
|
|||
|
|
Experts who have seen the report said it seemed to be based
|
|||
|
|
on sound research and appeared to have no obvious sources of
|
|||
|
|
experimental error, but they cautioned that other seemingly
|
|||
|
|
reliable reports have collapsed under close examination.
|
|||
|
|
|
|||
|
|
The work was performed by Hideo Hayasaka and Sakae Takeuchi
|
|||
|
|
of the engineering faculty at Tohoku University in Sendai, Japan.
|
|||
|
|
|
|||
|
|
Unlike the exaggerated claims made for low-temperature, or
|
|||
|
|
"cold," nuclear fusion this year, the current results are
|
|||
|
|
presented with scientific understatement. The authors do not claim
|
|||
|
|
to have defied gravity, but simply say their results "cannot be
|
|||
|
|
explained by the usual theories."
|
|||
|
|
|
|||
|
|
More important, the experiment is outlined in rich detail,
|
|||
|
|
ensuring that other scientist can try to duplicate and assess it.
|
|||
|
|
|
|||
|
|
"It's an astounding claim," said Dr. Rober L. Park, a
|
|||
|
|
professor of physics at the University of Maryland who is director
|
|||
|
|
of the Washington office of the American Physical Society, which
|
|||
|
|
publishes `Physical Review Letters'. "It would be revolutionary if
|
|||
|
|
true. But it's almost certainly wrong. Almost all extraordinary
|
|||
|
|
claims are wrong."
|
|||
|
|
|
|||
|
|
The experiment looked at weight changes in spinning
|
|||
|
|
mechanical gyroscopes whose rotors weighed 140 and 176 grams, or 5
|
|||
|
|
and 6.3 ounces. When the gyroscopes were spun clockwise, as viewed
|
|||
|
|
from above, the researchers found no change in their weight. But
|
|||
|
|
when spun counterclockwise, they appeared to lose weight.
|
|||
|
|
|
|||
|
|
The rate of decrease was small, ranging up to 11-thousandths
|
|||
|
|
of a gram when the gyroscopes turned at 13,000 rpm. But two
|
|||
|
|
effects were significant. First, the weight loss increased as
|
|||
|
|
speed did. Second, the pattern was stronger with the larger
|
|||
|
|
gyroscope, indicating that the results might be applied to still
|
|||
|
|
larger objects.
