The truth of science changes once we make new discoveries. As we advance through science, we end up "disproving" old theories that we once thought were true. Thus, with each and every new discovery we make, we can only name them "theories," because hypothetically in the future someone is ought to disprove it.
In class, we read an article titled "When Science Gets it Wrong." The article showed several examples of scientific discoveries that disproved old ones. One example was of genes and DNA.
The genes of a chromosome were once thought to be like instruction manuals for writing who we are, our bodies. Each gene would represent some trait of our body, as believed by the biologists of the 1950s. However, it turns out that a strip of genes can actually be cut up into different areas, and create new forms of instructions. The strands are cut up into introns and exons - the introns are removed from the strand, while the exons are kept in the strand. This is happens when proteins modify the RNA strand before it exits the nucleus. This results in a totally new strand that is made out of pieces from the original DNA, that can code for other proteins in the body.
I think it is amazing how science can move forward and prove itself wrong after time. I think that science is a very humbling subject, because scientists will eventually have to admit flaws in their theories as new theories are made. When we are young, however, we were taught theories in science as if they were facts. I remember some of my old-aged science teachers, who used to attend school long, long ago, used to say that some of the theories they are teaching now were different from the ones they learned when they were young. Even in one's lifetime, "scientific facts" around us can change. I think science is amazing because we are discovering the world while we are naive. We try to discover, with the knowledge that we will never eventually be able to discovery everything in the world. Yet, people still continue to discover.
