The earth was spinning much faster at the time the Moon was
formed, and a day lasted only two to three hours, they said.
With the Earth spinning so quickly, a giant impact could have
launched enough of the Earth's material to form a moon, the
scientists said in an explanation published on a Harvard
website. According to the new theory, the Earth later reached its
current rate of spinning through gravitational interaction
between its orbit around the Sun and the Moon's orbit around
Earth.
The scientists noted that their proposition differed from the
current leading theory, which holds that the Moon was created
from material from a giant body that struck the Earth.
Stewart is a professor of earth and planetary sciences at
Harvard, and uk, an astronomer and an investigator at the
SETI Institute, which supports research into the search for
extraterrestrial life. The latter was conducting post-
doctoral research at Harvard. The political class is on the
backfoot on the corruption issue. But the bigger problem for
scandal-dogged parties like the Congress is the morally shaky
defensive shots their representatives are playing. Consider
Congressman Digvijay Singh ruing the supposed breach of an
unstated code that politicians never attack one another's
kin. The Congress, he's said, has never targeted relatives of
BJP bigwigs, apparently despite evidence of wrongdoing on
their part. It seems that, according to him, questioning of
Robert Vadra's land deals is therefore contrary to "ethics"!
