A law school professor and former criminal defense attorney advises as to why you should never agree to be interviewed by the police.

Officer George Bruch from the Virginia Beach Police Department speaks at 27:21, and corroborate the professor's advise.

The video is 48 minutes, but is well worth watching. The professor is also quite humorous. ﻿

Neat. The peer-reviewed journal entry is here: http://iopscience.iop.org/2041-8205/795/1/L12/

Scientists measure a light source's distance in order to determine how long ago the light was emitted. Through a phenomenon called "Hubble's Law", light from distant sources becomes more "redshifted" the further away the source is from the viewer. An inexact example would be a blue light 1 billion lightyears away and one 2 billion lightyears away. The closer one might look green, but the farther one might look orange. Astronomers can then use what's known as the "Lyman alpha line", a constant and strong reference line emitted by nearly all celestial bodies, to find a reference for how far redshifted the viewed spectrum is. If, for example, the line is observed to be at 200nm, they can use the reference wavelength of 121.6nm to determine how far redshifted the light is (in this case, 78.4nm). They can then use Hubble's law to determine the source's distance, and then using the speed of light ~= 3x108 m/s, they can determine the 'age' of the light.
