I want to thank everybody who answered my nebula question. No wonder I couldn't find the name of earth's nebula on Google. No, I wasn't confusing nebula with anything else... I swear!

So life is sequence, energy is found in all living things. Light uses energy and the expansion of the universe is maybe disrupted by black holes that light cannot escape. So if energy is vaccumed in and the essence of life is the energy that has superceeded us. Is light the shadow of energy represented by the same sequence or one thats been vaccumed and rearraged into a chaotic representation of the expanding universe pushing our expelled energy farther away?

I would like to build a radio receiver capable of receiving around 140-160 mhz in NFM. I want to be able to get a clear signal to feed to my computer sound card, and also posibbly to a ADC later on. I want to be able to record in at least 96khz audio, if not higher. I have some basic knoledge of electronics, and was wondering if anyone knows how dificult this will be, and what parts and schematics i will need to have in order to build it.

Help:( I'm not so much interested in the answer to this as how to do it. I'm not sure how you figure out what the most stable ion would be for aluminum.

I have 2 parents, each of them has 2 parents and each of them has 2 parents etc etc. If i were to draw a family tree back from me and go back 30 generations (only 1000 years) the top line would have over 1 billion ansestors. and the total number of poeple in this tree would have more poeple than ever lived. This off course is not possible, where is the maths gone wrong?
