MadSci Network: General Biology |
Question #1: has life ever been recreated in the lab? Answer: No. But, by an amazing coincidence, I just came across a news release telling about some work done by physicists (who apparently have taken Biology 101) who have created cell-free protein readout systems "analogous to a conventional electrical circuit." As you put it: "an electro-biochemical process." http://www.rockefeller.edu/pubinfo/news_notes/rus_121203_h.php It is only a matter of time before artificial membranes are added and... Voilą! A man-made cell. Thus, the cell will be "reinvented" not "recreated" in the laboratory. Question #2: Where did the dust, and energy come from? I believe I remember someone saying that it always was. Is that about right? Yes, except that the available evidence suggests that the Universe did have a beginning. The theory is called "The Big Bang." The upshot of a "Big Bang" is that the dust (atoms, matter) and energy did take quite a while to develop into the forms we recognize today. Physicists revel in it. Here is a quote from one of many Web sites: "About 15 billion years ago a tremendous explosion started the expansion of the universe. This explosion is known as the Big Bang. At the point of this event all of the matter and energy of space was contained at one point. What existed prior to this event is completely unknown and is a matter of pure speculation. This occurrence was not a conventional explosion but rather an event filling all of space with all of the particles of the embryonic universe rushing away from each other. The Big Bang actually consisted of an explosion of space within itself unlike an explosion of a bomb were fragments are thrown outward. The galaxies were not all clumped together, but rather the Big Bang lay the foundations for the universe." http://www.umich.edu/~gs265/bigbang.htm Here are some other good links that discuss the Big Bang Theory in what seems to be an authoritative way: The Hot Big Bang Model http://www.damtp.cam.ac.uk/user/gr/public/bb_home.html The Big Bang Theory http://liftoff.msfc.nasa.gov/academy/universe/b_bang.html Big Bang Cosmology Primer http://cosmology.berkeley.edu/Education/IUP/Big_Bang_Primer.html Further reading at these sites may be enlightening. I wish you well with your commendable effort to reconcile the human need for spiritual satisfaction and answers to questions of existence with the reality of our current understanding of the Universe. I hope I have been of some help. Good luck!
