So, for example, while you would be technically correct in arguing that it takes a shorter amount of time for the Earth to fall to the Sun's surface than it would take to fall to the Sun's center under the assumption that all the Sun's mass is ...
Sunspots and the Rise and of Civilizations Maurice Cottrell
There appears to be a correlation between the rise and of civilizations with the rise and of radiation from the sun.

In the of 1831 Faraday attempted to determine just how an induced current was produced. His original experiment had involved a powerful electromagnet, created by the winding of the primary coil.
Meteors fall into the Earth's atmosphere all the time... tons of them every year. But when the Earth passes through the debris left behind by a comet, then you get lots of meteors at once.... a shower.

During the of 1995, the comet had a huge outburst in activity and shortly afterwards four separate nuclei were identified and labeled "A", "B", "C", and "D", with "C" being the largest and the presumed principal remnant of the original nucleus.
Moon rocks fall into two main categories, based on whether they underlie the lunar highlands (terrae) or the maria.
