In that case, the Projectile would
remain forever in the same spot, perfectly motionless as far as regards
the Earth and the Moon, though of course following them both in their
annual orbits round the Sun.
Such was now the state of things, which Barbican tried to explain to his
friends, who, it need hardly be said, listened to his remarks with the
most intense interest. How were they to know, they asked him, the
precise instant at which the Projectile would reach the neutral point?
That would be an easy matter, he assured them. It would be at the very
moment when both themselves and all the other objects contained in the
Projectile would be completely free from every operation of the law of
gravity; in other words, when everything would cease to have weight.
This gradual diminution of the action of gravity, the travellers had
been for some time noticing, but they had not yet witnessed its total
cessation. But that very morning, about an hour before noon, as the
Captain was making some little experiment in Chemistry, he happened by
accident to overturn a glass full of water. What was his surprise at
seeing that neither the glass nor the water fell to the floor! Both
remained suspended in the air almost completely motionless.
