Hi, again people! I played with small frequencies between 1-10 Hz this time. I had to use a square wave as my speaker wouldn't produce enough vibration on sine waves to have any moving light reflections. Unfortunately, video lost some of its sparks by reducing framerate from 50 which it was recorded at, to 24 FPS for youtube, it's all about FramePace ;-). I will keep that in mind when recording next time.

This video is about how Russian physicist Aleksandr Fridman corrected Albert Einstein about the expansion of the universe. Einstein thought that general relativity implied that space had to be static and unchanging, but he had made a technical error regarding the differentiation of the metric (in particular, I believe he mistook the determinant of the metric for a scalar rather than a tensor density of weight 2). Friedmann didn't make this differential geometric mistake, and the cosmologies he found from the Einstein Equations were more varied in their properties - they could be expanding, or contracting, or (with the cosmological constant), static.

In this video, Karl Battams of the Naval Research Lab talks us through a visualization of the comets that SOHO has witnessed. Since its launch nearly 20 years ago, NASA and the European Space Agency's Solar and Heliospheric Observatory has spotted 3000 comets. The mission's The Large Angle and Spectrometric Coronagraph (LASCO) instrument blocks out the bright solar disk, making it easier to see the corona of plasma and dust around the Sun, normally only visible during solar eclipses. This instrument also provides a very large field of view of the region around the Sun. This visualization utilizes SOHO data from 1998 - 2010 and shows over 2000 comets. Comets that were first observed by SOHO carry no labels, and comets witnessed by not discovered by the spacecraft are represented with their labels. Trails on the comets are color coded based on family: yellow - unaffiliated comets, red - Kreutz group, green - Meyer group, blue - Marsden, cyan - Kracht, and magenta - Kracht 2.

Planets and stars can be really big, but they pale in comparison to some of the largest black holes out there.
