"There is a huge force of gravity between the earth and moon some 70 million trillion pounds ... This causes the land and (especially) sea surfaces to bulge in response, as is apparent to us in tides. Because the presence of the moon over any part of the earth does not cause an immediate bulging response, this slight delay results in a continuous, slight, forward 'pull' on the moon, causing it to spiral slowly outwards, away from the earth. The rate at which the earth-moon distance is presently increasing is actually being measured at about 4 centimetres a year. It would have been even greater in the past. This immediately raises the question as to whether the earth-moon system could be 4.5 billion years old, as most evolutionists insist .... extrapolating backwards, the moon would have been in physical contact with the earth's surface 'just' 1.4 billion years ago.

"It can be demonstrated from known physical laws that the earth and the moon could not survive being within 11,500 miles of each other (the so-called Roche Limit), because the resulting tidal friction would be massive."

A star in the making
"The birth of a star has never been observed. The principles of physics demand some special conditions that make star formation very rare - if it occurs at all! A cloud of hydrogen gas must be compressed to a sufficiently small size so that gravity dominates In space, however, almost every gas cloud is light years in size, hundreds of times greater than the critical size needed for a stable star. As a result, outward gas pressures cause these clouds to spread out further, not contract A number of mechanisms have been proposed to explain the beginning of star formation. Most popular is a pressure or density wave in space, which might squeeze dust clouds down to star-forming size. This pressure is suggested to originate from a nearby supernova or exploding star. The net result of this reasoning is that stars are said to form from other stars. But where do the first stars come from in this circular reasoning?"
