For the first time in a while, there’s no real significant chance of any showers in the forecast for the next week. We will see temperatures drop a bit from the mid-60s on Thursday (under partly cloudy skies) to the upper 50s on Friday (with mostly sunny skies.) As we head into the weekend, the sunshine will continue, and the high temperatures will rise into the upper 60s Saturday and then into the low 70s on Sunday.

So does light go out of headlights of a car travelling at the speed of light? It’s comforting to know that even Einstein struggled with this concept prior to coming up with his theory of Special Relativity. But he discovered that time and space are not absolutes, and therefore the answer depends on your point of reference. If you are travelling inside the car, the lights will “beam out” at the speed of light from your frame of reference. But anything they shine on (including an observer) will look very different, thanks to a huge Doppler Shift, rendering it invisible to the human eye. So theoretically, an observer outside the car couldn’t see the car, and an observer inside the car couldn’t see anyone it was driving by because the Doppler shift would change the visible light into wavelengths beyond ultraviolet.

This is why I went into meteorology, and not theoretical physics.
