Dope thread, this is the most fundamental issue with current physics/technological advancements IMHO, and I think it has just has much to do with geopolitics, populace control and international finance, being that true applications of Einstein's theories would turn this world upside down in one day. First off I'd like comments on my post, if anybody feels it's wrong/incorrect, please comment, let's build knowledge brehs
With that said, first let's break it down as basic as possible with a few points:
1) Einstien's two part theory of relativity is a THEORY.
a)General relativity/Equivalence principle- states of acceleration motion = being at rest in a gravitational field. The big change between this and classical mechanics is that classical mechanics always has a "0" point. Meaning that you START to move with a certain impetus, meaning a certain applied inertial force. What Einstein basically said is that being at rest in a gravitational field does not mean you are still, or in other words, objects are ALWAYS moving. So essectially in in mechanical physics you are capturing an object from when its motion is 0 to when its motion is more than 0. Where as in the theory of relativity you aren't capturing anything, you are simply observing it over a period of time, of which that period of time differs according to who or how it is being observed. So meaning that all those Train A moving at 0 and Train B moving at 100 physics questions are basically erroneous relativistic physics, because you aren't taking into account the time-laps from which it's being observed. To a Newtonian physicist this is some
sh*t because Newtonian physics work 99.9% of the time on earth, F=ma on the macro and micro scale on planet earth.
b) Special relativity- laws of
physics are the same for all observers in
uniform motion relative to one another, and the
speed of light in a
vacuum is the same for all observers, regardless of their relative motion or of the motion of the
light source. To keep it simple the most important result of this is the now famous/infamous "E=mc^2", which basically means that mass = energy. Meaning that all entities with mass are actually entines with energy. Thus the inspiration for comics like the Fantastic Four character Silver Surfer or the X-man Cyclops. So basically you and I are balls of energy. So basically two things, 1) nothing is faster than light, since light is the free-est from of energy, and 2) basically mass and energy are proportional. So because mass and energy are proportional relative to speed, a small thing moving really is the same a big thing moving really slow, thus the origins of the atom bomb, particle acceleratios, nuclear fusion, etc. You can create huge amounts of energy moving small particles fast enough. The saddest thing about this theory is that it was developed in the early 1900s, here we are in 2014 still using fossil fuels to power our vehicles
Quantum Mechanics, while technically being a theory, is not in reality not. Your computer would not function without a clear understanding of quantum mechanics, electron spin direction, orbits, superpositions, etc. Personally I hate calling something a theory just because there is no mathematical redaction proving a formula that works 99.9% of the time, but math is harsh like that, there is no judge tougher than math in my opinion.
2) Einstein's theory is an assumption on basically why certain properties/physical laws go haywire in certain situations, it isn't a constructive theory. Meaning that meanwhile we use theory of relativity to account for certain issues with things like satellites sending signals back to the earth, we haven't created new technologies solely based on the theories/formulas of general relativity.
3) More than anything, Einstein's theories have to do with the time-space continuum. In mechanical physics, time is considered a physical constant, meaning that 1 second is 1 second, anywhere, anytime. In general physics velocity, acceleration, and force are the variables, meaning that you can contract/expand velocity, acceleration, and force with different vectors, what Einstein is saying is that you can affect TIME with different vectors, and that's what essentially is the trippy part. Thus the whole time travel generation etc. Basically, in essence, you can affect TIME with different vectors so to speak, meaning with the righ velocity/acceleration/force, etc, TIME changes.
The common example is holding your hand to the fire. To the observer 1 second is still a second, but to the person with their hand on fire 1 second feels like a million years.
In short, at least to me, the most fundamental part of Einstein's theory is that time is an object (if that's the correct word) that can be manipulated just like force. Meaning that with the right innovations we can make time move slower/faster, thus affecting/warping the physics within that "time-space". So basically, the next step to putting Einstein's theory to practical use is to manipulate time, and we all know the respective powers that be ain't gon' let Joe Schmo be allowed to start rolling the clock back whenever he feels like it
Let's build on this thread brehs, perhaps there's some developments in relativistic physics since I got out of school, and pleas dap, rep OP, and five star this sh*t
