APOD 3.1

Take a look at this. One star outshining an entire galaxy. This is a supernova, where, at the end of its life, one dying star shines brighter than the core of the spiral galaxy, composed of millions of other stars. Talk about going out with a bang. The description following this APOD is somewhat technical, and beyond my grasp. Basically, it deals with the majority of energy in the universe not being vested in stars, but in the actual void of space. How else could a single star outshine an entire galaxy? There seems to be much discord in the astronomical community as to the validity of this claim. The new (old) theory involves the use of a value designated as lambda, or a cosmological constant. The use of a mathematical concept sounds fine at first, but in use, it seems to muddle up things more. Cosmologists can accurately interpret data without the use of this constant.
