So my question delves more into the metaphysical and philosophical than super scientific, but it relates back to what we know about physics and science. Recently a friend and I had a mentally stimulating conversation and it got me wondering about something. Since the beginning of time, people have said they can do something, and the general public has denied that said person would be able to do it. The Wright brothers with flying, someone probably told Magellan he couldn't circumnavigate the world, and plenty have times has the mass public denied scientific postulates and theories that either later turned out to be true after refinement, or turned out to be true from the beginning. We now live in an age where we know more than ever before, there's so much to learn out there about ourselves, the Universe, the laws that bind us. We can use the internet, go to College, research, visit the library, there's so many ways to learn new things. My question comes back to this, now, I haven't delved much into physics yet. I am a physics major, but I have yet to take a physics class because of a few prerequisite conflicts and all that, but I'm highly interested in the subject. Certain scientific theories pose that certain things are impossible, Special Relativity says an object can not accelerate to the speed of light, right? Laws of thermodynamics state that as time goes on, entropy increases, the law of conservation of energy and mass says that mass nor energy can be created or destroyed. The scientists who came up with these laws are clearly not your basic nay sayers on the side of the street saying it's impossible because they don't believe it's possible, they're saying it because there is evidence and scientific proof. But as we all know, sometimes theories turn out to be wrong, or need to be adjusted, as we gain more information and insight. Are these laid out theories and laws set in stone? Excluding loop-holes like the theoretical Alcubierre drive which would bend space for transportation at "FTL" speeds, even though it's not technically travelling at the speed of light but bending space around it, will these theories and laws always be there for us to fall back on? Or will we someday learn that Einstein was wrong? That maybe there's a way to reverse entropy, that matter or energy could possibly be created? As impossible as these things sound, I would like intelligent individuals with an open mind to share their thoughts on this matter. Am I crazy, or will these theories and laws forever be in place and we will never actually be able to directly break or ignore them? I apologize if my basic understanding of Physics and Science isn't enough to articulate what I'm trying to ask. Hopefully if it's not, you guys can extrapolate.
