 May 8 comment What would happen if I were to fall into a massive hollow planet? If you had a planet in such a configuration, note that the atmosphere would get sucked into the center (through the hole you fell in, if nothing else). So inside the shell you would experience (slight) gravitational pull toward the center, and potentially a lot of air resistance, depending on how much atmosphere the planet has. Jul 24 comment Is speed of light and sound rational or irrational in nature? @BobJarvis "Defined by" definitely doesn't mean "defined as". Specifically, its the distance traveled by light in 1/299,792,458 of a second. Jul 23 comment Is speed of light and sound rational or irrational in nature? @DavidZ Yeah, my phrasing wasn't terribly precise. By "the speed of light in m/s" I really meant c/(1 m/s). Jul 23 comment Is speed of light and sound rational or irrational in nature? In the metric system, the meter is defined by the distance light travels through a vacuum in one second, so the speed of light in m/s is definitionally rational. Jul 10 comment Why does wavelength affect diffraction? You stuffed the actual answer to the question in one sentence near the end. I don't see how "oh, and travel length to weight is based on wavelength" gives any intuition - you just stated what happens. The whole setup is only useful if you can explain why travel length->weight is dependent on wavelength.
