Expanding Earth - xkcd

After the first day, the Earth would have expanded by 864 meters. Gravity would take a long time to increase. If you weighed 70 kilograms when the expansion started, you'd weigh 70.01 at the end of the day. What about our roads and bridges? Eventually, they would have to break up, right? Not as quickly as you might think.

Jun 15, 2009 . The fluctuations in gravity are “possible” (heavy emphasis on the quotes!), but only in the sense that a super-strong magnetic field can affect neutral matter by diamagnetic properties. In fact, it's just not gonna happen by accident out in the wild. And the Moon, as an orbiting satellite, can only spiral steadily.
